An automobile is a self propelled vehicle driven by an internal combustion engine and is used for transportation of passengers and goods on ground eg bus, car, jeep, trucks. Modern automobile consists of a frame supporting the body and certain power developing and transmitting units which are further supported by tyres and wheels through springs and axles. The engine supplies the power which is delivered by the transmission system to the wheels through the clutch or fluid coupling.
The following are the uses of diesel engine in cars, the diesel fuel is more cheaper than petrol, the diesel engine uses 50% less fuel in heavy traffic than does the available spark ignition engine and note that one extra economy is that diesel's good low-speed torque makes it possible to drive at low speeds in a higher gear. The high thermal efficiency of the diesel engines reflected in low specific fuel consumption given its high advantages in the matter of range.
The crankshaft speed of about 5000 rpm enables the diesel engine to propel cars at high speeds with acceleration comparable to that of the spark ignition engine. The diesel engine is somewhat amazing and many individuals would actually appreciate this if they study a lot of them. The use of diesel eliminates the complication of spark ignition with its spark plugs, breaker points, condenser, ignition cables, distribution rotor and other components that may have to be replaced several times during the life of the engine.
Operating tests are further reduced by having no carburettor to service periodically. Owing to the absence of electrical ignition equipment, non-volatile fuel and power exhaust temperature, the diesel engine has a much smaller fire risk than the petrol engine when working in closed places and in the neighbourhood of inflammable material.
In all my research of the diesel engines, there is something that I really love and it is a special feature of the diesel engine called "torque back up" ( an inbuilt performance feature) makes it convenient for the vehicle to climb a steep incline with low consumption at high load.
