The engine is the heart of a car. It is a complex machine built to convert the heat from combustion gases into the forces that turn the wheels on the road. It consists of two main parts. The heavy part at the bottom is the cylinder block, which is the housing for the main moving parts of the engine. The cylindrical block supports pistons, crankshaft, connecting rods and oil pans. The detachable upper cylindrical head supports the camshaft, cam, intake and exhaust valves to open and close as the air-fuel mixture enters the combustion chamber. In most automobile engines, the explosive force of the air-fuel mixture drives the piston. The pistons turn the crankshaft to which they are mounted. The torque of the crankshaft causes the wheels of the car to rotate.
Here we will look at the major parts that make up an engine.
