Abstract

in the past 20 years, rapid development in the automotive industry have been accompanied by increase in speed, loads and engine power. This paper is reports on review of modification of final drive mechanism in Toyota In nova car (diesel engine).Final drive mechanism is used in rear wheel drive engines. With the help of propeller shaft and differential, engine power is transmitted from engine to the rear wheels of the car. Now-a-days, Toyota In nova car makes too much noise and comparatively high RPM at high speed of engine (in running condition). The study shows that in today’s In nova car engine makes above 2500 rpm on reaching 100kph in 5th gear and makes loud noise in cockpit. Driving at 60 kph in 4th gear the engine is at 2000 rpm and changing up to 5th gear drops the revolution to more quite 1500 rpm. Driving at 50 kph in a fourth gear result in the same engine speed but the engine doesn’t like being driven like that, it labours a bit. At 80 kph in the 5th gear the engine is doing 2000 rpm and taking the Innova 100 kph in the 5th gear result in engine speed of above 2500 rpm. Thus at highway speed the loud engine noise makes one feels that an additional gear would have been handy. The core agenda of the project is to modify final drive mechanism of Toyota Innova to reduce RPM and noise of engine with the help of changing crown-pinion ratio, when car is in running condition. We have gathered a final and concurrent conclusion to this problem with use of the AUTOCAD and SOLID WORKS analysis.
