Universal joints are used for connecting two shafts inclined at angles to one another. For transmitting the rotary motion from the engine to the road wheels throughout the variations in position of the rear axle with respect to the gear box and chassis, universal joints are most suitable. It shows the principle of universal joint.

It is caused by the fuel with a low octane rating and is the tendency for the fuel to autoignite in an engine combustion chamber. The resulting knock or ping is the sound of the pistons slamming against the cylinder walls. Severe detonation can break pistons and destroy engines. This early ignition of fuel creates a shock wave throughout the cylinder as the burning and expanding fuel air mixture collides with the piston that is still traveling towards T.D.C. (top dead center) .

All the engines have hydraulic valve lifters in one form or another. The most common types of engine that has them is your vehicle engine. They created to get rid of the need for combustion engines to have mechanical clearance in the engine valve train. The reason that clearance is required is to keep the valve from being held open and destroyed as the valve train goes through its process of thermal expansion. In in effect, hydraulic valve lifters keep the valve healthy and protected from an engine normal thermal expansion process.
