The engine is the heart of mechanical equipment, and this heart is related to the service life and efficiency of construction machinery. In the construction machinery industry, most engines are diesel engines, invented by the German inventor Rudolf Diesel in 1892. To commemorate the inventor, diesel is represented by his surname Diesel, while diesel The engine is also called a diesel engine.
The advantages of a diesel engine are high power and good economic performance. Each working cycle also undergoes four strokes intake, compression, work, and exhaust.
Cumbersome, loud noise and black smoke give many people have a wrong impression of diesel engines. After years of research and new technology applications, the status quo of modern diesel engines is no longer comparable to the past. Modern diesel engines generally adopt technologies such as electronically controlled injection, common rail, and turbocharged, They have made breakthroughs in weight, noise, and smoke, reaching the level of gasoline engines.
The diesel engine electronic control injection system consists of three parts: sensor, ECU (control unit) actuator. Its task is to electronically control the fuel injection system to realize real-time control of fuel injection volume and timing according to operating conditions. Using sensors such as speed, temperature, pressure, etc., the real-time detected parameters are synchronously input into the computer, and compared with the parameter values stored in the ECU, After processing and calculation, the actuator is controlled according to the optimal value, and the fuel injection system is driven to make the diesel engine operate in a state. Achieve the best.
