It was manufactured by Rudolf Diesel in 1892 and works with a self-ignition system. In this case, the spark plug is not needed to ignite the fuel and air mixture. Air suction is performed with suction power and suction intensity at the highest level. Thanks to the compressor, the temperature rises to an estimated 700-900 degrees. Diesel fuel is added to this heat and it is spread thinly by the injection pump. In this way, the mixture is ignited. Thanks to this ignition, pressure builds up and the pistons move downwards. This becomes the only real and functional movement. The exhaust gases are thus directed to the exhaust via the valve.
Diesel vehicles are distinguished from others thanks to the injection system. Older engines run with a tank injection system. In this system, the fuel is not directed directly to the ignition area, but to the front tank area, located at the top of the cylinder. Here ignition takes place and is transferred to the ignition area. Newer diesel engines have direct injection. In this way, the fuel is sent directly to the ignition area. This requires a stronger spray. Modern diesel engines work with a pump-injection or Common-Rail-injection system. In the pump-spray system, the injection pump and the injection nozzle create equality. Therefore, an injection of 2000 bar is possible. In common rail operation, there is a full-length tank in the cylinder head, where diesel fuel is held at high pressure, around 1200 bar. Spraying takes place over the injectors. These are electronically actuated and can perform multiple spraying motions with a single finesse. In this way, ignition is optimized.
Diesel Engines
Diesel engines have a higher efficiency rating than Otto engines. For this reason, fuel consumption is lower. However, in the ignition of the fuel, particles that harm health are formed. In newer engines, filters are installed for the substances that are harmful to health, and thanks to this filter, a reduction of up to 95% has been achieved.
