They hold the other half of journal bearing and have two holes in their casing through which we insert bolts and fasten them in internally threaded holes of engine head thus we hold our camshaft between the casted journal seat in engine block and cam-caps and fasten them up with long bolt. Obviously, it is a very important part of the automobile because in the absence of an engine, the automobile may not move at all, and its basic function of transporting passengers or goods would be defeated. The diameter of these holes is called the bore of an engine. The suspension system absorbs the vibrations due to up and down movement of wheels. It is also called as oil sump. The moving parts in an engine need regular lubrication to reduce unwanted friction. It is an ‘I’ shape structure whose one end is connected to piston and other one to crankshaft. It may be a ‘dead’ axle if no power is supplied to it and it is just supporting the weight of the vehicle. The mold is made such that we should have required number of holes in the casted block, which are said to be the number of cylinders of an engine or engine cylinders. It retains lubricating oil in it which is pumped to different engine parts. The mold is made such that we should have required number of holes in the casted block, which are said to be the number of cylinders of an engine or engine cylinders. Hydraulic and Pneumatic Systems . Obviously, when we have reached our destination, we would like to stop; and therefore, the vehicle should come to rest. The other parts of the chassis are suspension system, axles, and wheel. Compressor 2. Two studs are used for holding one bearing-cap in place. Wait what it would cause?, friction if one cylinder (piston) moving up and down in another cylinder? Springs and shock absorbers connecting the frame and the axle perform this function. This causes a reduction in speed of the vehicle and brings it to rest when necessary. It also withstands the centrifugal forces while cornering and takes up stresses due to the rise and fall of axles. We have some more holes along the length of engine cylinder, these are water and oil flow paths required for cooling and lubrication of an engine. The differential is the next component of the transmission system. The engines used are multi-cylinder engines. ... or fiberglass parts that form the passenger compartment and serve as an attractive covering for the chassis.
