TRI-BRID VEHICLE

ABSTRACT

In automobile sector, the need for alternative fuel as a replacement of conventional fossil fuel, due to its de-pletion and amount of emission has given way for new technologies like Fuel cells vehicles, Electric vehicles.
Still a lot of advancement has to take place in these technologies for commercialization. The gap between the current fossil fuel technology and zero emission ve-hicles can be bridged by tri-brid technology. Tri-brid ve-hicles are those which can run on three power-ing sources/fuels. Feasibility of this technology is been proved in four wheelers and automobile giants like Toyota, Honda, and Hyundai have launched successful vehicles like Toyota prius, Honda insight etc.

This technology maximizes the advantages of the three fuels and minimizes the disadvantages of the same. The best preferred tri-brid fuels are compressed air, electric and fossil fuel. This increases the mileage of the vehicle twice the ex-isting and also reduces the emission to half. At present, we like to explore the tri-brid technology in the two wheeler sector and its feasibility on road. This paper deals with an attempt to make a tri-brid vehicle with compressed air, electric start and petrol run. Further a design of basic tri-brid elements like motor, battery, compressed air and engine. As on today, tri-brid products are one of the best solutions for all pollution hazards at a fairly nominal price.An investment within the means of a common man that guarantees a better environment to live in.

INTRODUCTION TO TRI-BRID VEHICLE

Since the last two decades the judiciary and policy mak­ers all over the world are deeply concerned about the urgent need for protection of the environment, ecol­ogy and humanity at large, there has been a steep rise in the accumulation of greenhouse gases particularly

CO2, which effect global changes in weather. Motor vehicle contribute about 14% of CO2from all sources besides, pollution due to both petrol and diesel engine driven vehicles caused by the emission of CO, no un­burnt hydrocarbons, particulate and oxides of tetra ethyl, Lead are injury to health and environment.

Regulations on exhaust emission from vehicle engines have been made progressively more and more stipend towards the year 2000 and beyond, Vehicle manufac­tures have been hence obliged to meet these stan­dards by designing cleaner and fuel efficiently engines and through provision for treatment of exhaust gases to satisfy the specified limits. So to satisfy and over­come these two problems namely.

•Pollution and

•Efficiency

THE PROJECT

The project entitled “Tri-Brid vehicle”, mainly concentrated on designing , drafting, fabrication of a vehicle that runs on the energies of petrol, battery, compressed air. The vehicle consist of a air cylinder which stores compressed air at certain pressure that is required to drive the piston in the reciprocating motion. The power is then transmitted to the rear wheel with the help of chain drive connected to the sprocket of rear wheel and shaft of the motor.

The vehicle is basically rear wheel driven and the direction is guided using the handle employed at the front wheel and the braking system is provided with a drum brake at the rear wheel.

The compressed is sent into the engine with help of the nozzle pipes connected at the inlet and the energy in the compressed air drives is the piston in reciprocating motion. The reciprocating of the piston is converted into rotational motion by the help of the crankshaft.

The chassis is designed in such a way that it is optimal for a two wheeler and designed for a concept that driving a single wheel is easier than driving two wheels. The whole vehicle has comparatively low kerb weight than the regular automobile vehicles because of the metal than has been used in fabricating the chassis.

The lubricating is similar to that of an engine by inducing gear oil that reduces friction between the piston and cylinder and enables smooth run of the engine.

The project employs an air cylinder which acts as the prime centre of providing the source of power for whole system. The air inside the cylinder is passed into the engine with help of the pipes that operates on open and close of the valve provided at the driver.

This cylinder when runs out of air, can run it with petrol and later can run on battery also until u refill the compressed air tank with the compressed air.
