Diesel engines
The engine is the power plant of the vehicle. In general, internal-combustion engines are used operating with some fuel (petrol, benzol oil). Depending on their combustion process, the engines are fundamentally classified as carburettor engines and Diesel engines
Sometimes, the carburettor engines are called light-oil engines and the diesel engines are called heavy-oil engines.Another difference results from the working method of the internal-combustion engine. A difference is made between Four-stroke cycle engines and two-stroke cycle engines.
The engine is assembled of various cast pieces: its foundation and main stationary body is formed by the cylinder block with the top portion of the crankcase to which the cylinder heads and the bottom portion of the crankcase are bolted. The crankcase with its main bearing houses the crank-drive assembly, comprising the pistons, the wrist-pins, the connecting rods and the crankshaft. Besides, the valves, valve-operating mechanism with camshaft, control gears and valve tappets, ignition system, carburetor, water pump, fan, fuel feed pump and oil pump are parts of the engine.
Arrangement and number of cylinders in the engine are decisive for its external shape. There are motorcar engines with two, there, four, six, eight, twelve and more cylinders arranged in various forms to each other. In most cases they are arranged in one block (cylinder block).
