Diesel engine (also known as compression ignition or CI engine), named after Rudolf Diesel engine, is an internal combustion engine. In this engine, due to mechanical compression (adiabatic compression), the air temperature in the cylinder increases, causing the fuel to ignite. The best thing about a four cylinder engine is that it's very sophisticated. Now all engines are four stroke engines (intake, compression, power, exhaust). With the 4-cylinder engine, the overall balance is perfect. The 4-cylinder engine is more suitable for delicate and powerful power output. A four cylinder engine generates power every 180 degrees of crankshaft rotation. 4 Cylinder Diesel Engine we produced always match to buyers demand with low price and high quality.
