We have seen how severe is bus disasters on fire, accident etc, to avoid causalities and human lives here we are proposing power window mechanism. On sensing any danger in the form of fire and smoke the window automatically will slide down making way for passenger way out from the vehicle. This cool device is the heart of a power-window system. The win-dow lift on most cars uses a really neat linkage to lift the window glass while keeping it level. A small electric motor is attached to a worm gear and several other spur gears to create a large gear reduction, giving it enough torque to lift the window. An important feature of power windows is that they cannot be forced open — the worm gear in the drive mechanism takes care of this. Many worm gears have a self-locking feature because of the angle of contact between the worm and the gear. The worm can spin the gear, but the gear cannot spin the worm — friction between the teeth causes the gears to bind.



A jack is an important accessory with a light motor vehicle as well as heavy motor vehicle. It is used to lift the vehicle in order to replace the wheels easily. All existing jack’s that are in use with a light motor vehicle are operated manually causing inconvenience and unnecessary wasting of time. This project is concentrated on modifying the existing screw jack to enable easy lifting of the motor vehicle in a very short interval of time by using starters, which are controlled by starter switch without any effort. In this project we are mainly replacing the nut of the screw jack with a couple geared with D.C. motor. In modern days, human being have become more fashionable that he does not want even a little bit of his effort to be used. So, we made a attempt in our project to reduce the human totally in lifting the vehicle with the help of our motorized screw jack.


Man has always been searching for various means to make life easier for him. With the advent of inflatable tyres, came the problem of punctured tubes and as a result the challenge to lift the car in order to place the wheel, the idea of jack was born. Today various types of jacks are available in the marked. With the objectives of reducing the human effort and comfortable lifting of vehicle, we are trying to make an attempt to modify the existing mechanical screw jack into motor-operated screw jack to lift the light motor vehicle.


1. Human effort is not required in lifting the jack.

2. Vehicle up to 5000 N can be lifted if high power motor provided

3. Since it is compact and occupies less space, it is portable

4. We have used starter motor, it can be driven by the car battery, hence it can be carried anywhere along with the vehicle and can be used to replace the tyres anywhere and anytime.

5. It produce music or sound while goes to upward and downward

6. Option we can connect the spy camera with this jack for monitor the bottom area of the car



Lack of space availability has always been a problem in urban areas and major cities and to add to it there are cars parked callously on the streets that further limit the space. In order to handle the issue of parking in busy places various types of vehicle parking systems are used worldwide namely Multi-level Automated Car Parking, Automated Car Parking System, Volkswagen Car Parking[1] and many more. The present project work is aimed to develop a reduced working model of a car parking system for parking 6 to 24 cars within a parking area of 32.17 m². It is an amalgamation of the already developed parking systems with the added advantage of reduced space occupancy by the design of a simpler and compact parking system that is rotary and occupies vertical parking space. The chain and sprocket mechanism is used for driving the parking platform and a one fourth hp brake motor shall be implemented for powering the system and indexing the platform. The platform is fabricated to suit the working model. The procurement and manufactured items are in hand and are ready to be assembled with the structure. This model is further useful for various branches of engineering in order to develop different types of automations like PLC, micro controller and computerization. By testing and analyzing the working model we can definitely get the view to develop the parking lots at difficult and busy commercial places.


The Rotary Automated Car Parking System (RACPS) belongs to the class of rotary smart car parking systems. The traditional parking systems such as multilevel or multi-storey car parking systems (non-automated), robot car parking systems, automated multilevel car parking systems etc have been implemented on a huge scale. But these systems have a major disadvantage of large space consumption which is successfully eliminated with the use of a rotary car parking system [2]. Moreover, the latter provides the added benefits of flexible operation without the need of an attendant and added security and least chances of vehicle damage. Since the model makes use of composite parts, it is easy to assemble and dismantle and is thus more convenient than the traditional car parking systems. The rotary model is specifically designed to accommodate multiple cars in the horizontal space of two. The structure can accommodate six cars in the space of two and can even be customised to hold a greater number depending upon the requirements of the user and can be efficiently put to use in much space crunched areas. Parking spaces cannot cope with the growth of the number of vehicles. In many urban housing societies, the parking space ratio is 1:1. The vehicles parked randomly, cause the major problem faced in most of the metropolitan cities. depicts the interconnection between the various subsystems of the project. Mechanical parking equipment is also called stereo garage. As compared to the existing parking arrangements, the most obvious advantage is maximum space utilization; it is safer and more convenient. The RACPS is totally automated with the user being given a unique ID corresponding to the trolley being allocated to him/her. This kind of equipment is useful to solve the issue of limited parking space available in busy cities. Evidently, it can be seen that the number of private cars is increasing every year. Private garages, where only a single car can be housed at a time, do not provide a feasible solution to the problem since many families own more than one car. So the task was to design mechanical equipment that can store 6 cars in one normal garage. It is called a rotary parking shaft. The idea is to park and move cars with no disturbance to the already parked cars in RACPS.


It ensures quick and automated parking and easy retrieval of vehicles.  Up to 6 cars can be easily and safely parked in the designed model.  The surface space required is equivalent to the parking space of two cars only.  Most suitable for parking in offices, malls and similar places .  The RACPS is engineered to ensure driver safety by use of an electronic safety zone.  Low maintenance levels are required by the system.  Does not require any parking attendant.  It can be easily constructed in a small area, just requiring a simple concrete base and 3 phase electricity. FUTURE ENHANCEMENT The RACPS can be installed with a safety installation such as, whenever there is human movement in the system, the rotation of the system should be immediately stopped. The platforms can also be equipped with safety sensors guiding the movement of vehicles in the platforms. Moreover, the model can be programmed in such a way that the trolleys traverse the minimum possible distance during parking as well as the retrieval of the vehicle.


Although the construction of this system seems to be easy, it will be difficult to understand without the knowledge of material’s , chains, sprockets, bearings, machining operations, kinematic and dynamic mechanism’s. All the calculations are done and accordingly each and every part of the parking system is bought into reality.


For designing the parking system proper views of the design were made. Top,Front and Side views are made, as shown below, according to the model of Rotary Automated Parking.




Brakes are employed to stop or retard the motion of any moving body. Thus, in automobiles the brakes are having the most important function to perform. In conventional braking system the motion is retarded or stopped by absorbing kinetic energy by friction, by making the contact of the moving body with frictional rubber pad (called brake liner) which causes the absorption of kinetic energy, and this is wasted in form of heat in surroundings. Each time we brake, the momentum of vehicle is absorbed that it has gained and to re-accelerate the vehicle we have to start from the scratch to redevelop that momentum by using the more power from an engine .Thus, it will ultimately result in huge waste of energy. As the basic law of Physics says „energy can neither be created nor be destroyed; but it can only be converted from one form to another‟, it will be good if we could store this energy somehow which is otherwise getting wasted out and reuse it next time we started to accelerate. That’s the basic concept of regenerative (“regent”) brakes, which provide braking for the system when needed, by converting the available energy to some usable form. These are widely used in electric trains and the latest electric cars.


Regenerative brake is an energy recovery mechanism which slows a vehicle by converting its kinetic energy into another form, which can be either used immediately or stored until needed. Thus, the generated electricity during the braking is fed back into the supply system (in case of electric trains), whereas in battery electric and hybrid electric vehicles, the energy is stored in a battery or bank of capacitors for later use. Energy may also be stored by compressing air or in a rotating flywheel. Electric and hybrid electric vehicles typically employ motor-generators that can convert electric current into torque (like a motor) or torque into electric current (like a generator). When the brakes are applied, the motor-generator provides the resistance necessary to slow the vehicle as it supplies current to the battery. In the event that the motor-generator cannot slow the vehicle fast enough, a torque coordinator module will apply traditional friction brakes to the extent necessary. Some regenerative braking systems store the recaptured energy mechanically, typically by pumping hydraulic fluid into an accumulator where the energy is stored in a REGENERATIVE BRAKING SYSTEM FOR BICYCLE USING FLYWHEEL


The regenerative braking system delivers a number of significant advantages over a car that only has friction brakes. In low-speed, stop- and-go traffic where little deceleration is required; the regenerative braking system can provide the majority of the total braking force. This vastly improves fuel economy with a vehicle, and further enhances the attractiveness of vehicles using regenerative braking for city driving. At higher speeds, too, regenerative braking has been shown to contribute to improved fuel economy – by as much as 20%. Consider a heavy loaded truck having very few stops on the road. It is operated near maximum engine efficiency. The 80% of the energy produced is utilized to overcome the rolling and aerodynamic road forces. The energy wasted in applying brake is about 2%. Also its brake specific fuel consumption is 5%. Now consider a vehicle, which is operated in the main city where traffic is a major problem here one has to apply brake frequently. For such vehicles the wastage of energy by application of brake is about 60% to 65%.

Types of Regenerative Braking System Based on the storage of energy, there are four types of regenerative braking systems:

1. Electrical Regenerative Braking

2. Hydraulic-based Regenerative Braking

3. Mechanical Regenerative Braking

4. Regenerative Braking using Compressed Air FLYWHEEL Flywheels have been used in cars for a very long time, but they haven‟t been used as kinetic energy restoration systems until recently. The flywheel‟s main use in cars is to convert the power from the engine and transfer it to the clutch plate. An internal combustion engine generates its power by firing pistons. Only one in four of these strokes actually drive the vehicle. This means that the output power of the engine is not steady. This problem is less severe the more cylinders a car has, since the pistons will be firing at different times to make up for the long gaps. Regardless of how many cylinders are present a flywheel is still needed to maintain a steady power supply. The idea of adding a flywheel is very appealing because it could increase the efficiency of what is already considered an efficient machine. The only concern could be the weight of the flywheel. However when added to the bike it would make a significant difference in accelerating the bike. The basic idea is that the rotating part of the engine incorporates a wheel with a very heavy metal rim, and this drives whatever machine or device the engine is connected to. It takes much more time to get a flywheel-engine turning but, once it’s up to speed, the flywheel stores a huge amount of rotational energy. A heavy spinning flywheel is a bit like a truck going at speed: it has huge momentum so it takes a great deal of stopping and changing its speed takes a lot of effort. That may sound like a drawback, but it’s actually very useful. If an engine supplies power erratically, the flywheel compensates, absorbing extra power and making up for temporary lulls, so the machine or equipment it’s connected to is driven more smoothly


The main objectives of this project are: 

To fabricate a regenerative braking system on a bicycle using a flywheel.  To decrease the energy lost from braking by storing that energy in a device, which in this case is a flywheel.  To achieve efficient braking by converting the energy loss into energy gain.  To store energy while braking.  To return the stored energy to the main drive.


Advantages of Regenerative braking

1. Efficient use of brakes.

2. Energy loss is converted into energy gain, i.e., energy is effectively utilised

3. In electric vehicles, it allows batteries to be used for longer periods of time without the need to be plugged into an external charger.

4. In some cases, it has helped in increasing the fuel efficiency of a vehicle.

5. In case of regenerative braking in electric trains, when the motor is not receiving power from the battery pack, it resists the turning of the wheels, capturing some of the energy of motion as if it were a generator and returning that energy to the battery pack, hence helping in wear reduction.

6. Braking is not a total loss, because in regenerative braking there is no heat loss associated with braking.


1. Regenerative braking is not effective at lower speeds, because the energy generated is not sufficient.

2. It is not possible to bring the vehicle to a full halt in case of regenerative braking.

3. The friction brakes are a necessary back-up in case of failure of regenerative brakes. Hence regenerative brakes are always used only in conjunction with conventional brakes.



As the world is hard pressed with the energy and fuel crises, compounded by pollution of all kinds, any technologies that bring out the solutions to this problem is considered as a bounty. In one of such new technologies, is the development of a new engine called as compressed air engine which does not require any of the known fuels like diesel, petrol, CNG, LPG, hydrogen etc. this works using only compressed air. This replaces all types of to-date known fuels and also permanently solves the problems of pollution as its exhaust is clean and cool measured practically as low as 5ºC. A proto type, a horizontal, single cylinder low speed engine was modified to run on compressed air. Since this engine runs only on high pressure compressed air, the exhaust of which is undoubtedly only air, making it a zero pollution engine. No heat is generated because there is no combustion of fuel, hence this engine needs no cooling system and it result in reduced cost, weight, volume and vibration. Early cost analysis shows that it’s very cost effective and the operational cost is ten times less than that of petrol or diesel. Experimental analysis were carried out on this modified engine to find out its performance characteristics like brake power, mechanical efficiency, overall efficiency, air to Air ratio, volumetric efficiency, cost analysis etc. Though the efficiencies were low as the frictional forces were high for the proto designed engine, however the concept can be applied on a professionally designed engine to improve its performance. Introduction Gasoline is already the fuel of past and also main reason behind global warming. But here we have the solution. A compressed air vehicle (CAV) is powered by an air engine, using compressed air, which is stored in a tank. Instead of mixing fuel with air and burning it in the engine to drive pistons with hot expanding gases, compressed-air vehicles use the expansion of compressed air to drive their pistons. One manufacturer claims to have designed an engine that is 90 percent efficient.



The aim is to design and develop a control system based on intelligent electronically controlled automotive braking system is called “INTELLIGENT REVERSE BRAKING SYSTEM”. Sensor Operated Pneumatic Brake consists of IR transmitter and Receiver circuit, Control Unit, Pneumatic breaking system. The IR sensor is used to detect the obstacle. There is any obstacle in the path, the IR sensor senses the obstacle and giving the control signal to the breaking system. The pneumatic breaking system is used to brake the system. So basically here the car brakes on its own by determining the distance from the object. The IR TRANSMITTER circuit is to transmit the Infra-Red rays. If any obstacle is there in a path, the Infra-Red rays reflected. This reflected Infra-Red rays are received by the receiver circuit is called “IR RECEIVER”. The IR receiver circuit receives the reflected IR rays and giving the control signal to the control circuit. The control circuit is used to activate the solenoid valve. If the solenoid valve is activated, the compressed air passes to the Single Acting Pneumatic Cylinder. The compressed air activate the pneumatic cylinder and moves the piston rod. If the piston moves forward, then the breaking arrangement activated. The breaking arrangement is used to break the wheel gradually or suddenly due to the piston movement. The breaking speed is varied by adjusting the valve is called “FLOW CONTROL VALVE”. The compressed air flow through the Polyurethane tube to the flow control valve. The flow control valve is connected to the solenoid valve. Braking is nothing but bringing a moving vehicle or moving body to a stop. Nowadays safety is an important feature in the automotive industry. The intelligent braking system is the next step to automation. Presently cars have the alarm system where when the car gets too close to an object an alarm is triggered which warns the driver about an object close by. But this feature has produced lot of problems and are prone to human error. We have enhanced the facility by using the same system but we have altered it so that the car brakes automatically when an obstacles close by. The aim is to design and develop a control system based on intelligent electronically controlled automotive braking system


FABRICATION OF AIR BRAKE SYSTEM USING ENGINE EXHAUST GAS SYNOPSIS The aim is to design and develop a brake system based on exhaust gas is called “AIR BRAKE SYSTEM USING ENGINE EXHAUST GAS”. The main aim of this project is to reduce the work loads of the engine drive to operate the air compressor. In this project, we used exhaust gas from the engine to rotate the generator turbine. Then the power is loaded to the D.C compressor and it is used to the pneumatic cylinder to apply brake. INTRODUCTION This is an era of automation where it is broadly defined as replacement of manual effort by mechanical power in all degrees of automation. The operation remains an essential part of the system although with changing demands on physical input as the degree of mechanization is increased. Degrees of automation are of two types, viz. Full automation. Semi automation. In semi automation a combination of manual effort and mechanical power is required whereas in full automation human participation is very negligible.
