Engine Working Of Car Engine Helpful Information Engine's are designed to have any number of cylinders and are created in all sizes. The pistons are designed to fire consecutively to rotate the crankshaft inside the engine block. Motor oil is used to cool and lubricate internal engine parts including the crankshaft, camshaft, cylinders, pistons, piston rings, wrist pin, lifters, rock arm, followers, intake and exhaust valves, timing gears and chain. The oil then travels back into the oil pan creating a recirculation system. The oil pump determines the amount of oil pressure the engine will have via a pressure spring fitted into a relief valve of the pump. There are primarily two styles of valve train systems, "overhead cam" which consists of a camshaft mounted on top of the cylinder head, and  "in block" systems which consist of a camshaft mounted inside the engine block, designs to perform this action will vary depending manufacturer. The cylind...

Serpentine Belt Tensioner Working Of Serpentine Belt Tensioner Helpful Information There are many configurations of belt tensioners but all follow the same principle. When these units wear they allow the belt to squeal and pop with eminent failure in the near future. These units are non-adjustable and require no maintenance expect for replacement. Some tensioners feature a replacement pulley separate from the housing a spring assembly. Step by step guide on how a serpentine belt tensioner works, this information pertains to most vehicles. Step 1  - A serpentine belt tensioner is designed to hold a prescribed amount of tension to ensure the proper operation of the serpentine belt, his tensioner is comprised of a housing, spring, idler pulley w/bearing, pivot and mounting bolts. Serpentine Belt Tensioner Step 2  - In time, the pivot bulkhead will wear allowing the belt to become misaligned which results in belt operation failure, the tensioner must then ...

Camshaft Variable Valve Timing Working Of Camshaft Timing Camshaft A Camshaft is commonly used to operate poppet valves in an internal combustion engine. A camshaft is situated in the cylinder block or cylinder head which has oblong lobes or cams which causes a tappet or lifter to open and close the intake and exhaust valves. This force is applied on the valve directly or through an intermediate mechanism such as a rocker arm, lifter, follower or tappet. Push rods are used to connect the camshaft to the rocker arm via the lifter. Each valve utilizes a spring which returns the valve to their original position (closed.) Camshafts are designed according to the RPM and horsepower range desired. When the intake valve is opened, the piston travels downward pulling in an air-fuel charge into the cylinder. This intake charge is a mixture of air and fuel which is ready for combustion. The faster the engine is running the faster the air and fuel mixture moves into the cylinders. Th...
