Diesel generator set is a diesel engine that extinguishes diesel oil to obtain energy release. The advantages of diesel generator set are high power and good economic performance. The operation of the Diesel generator is similar to that of the diesel generator set. Each operation cycle goes through four strokes: intake, compression, and exhaust.
However, since the fuel used for diesel generator set diesel engine is diesel, its viscosity is larger than that of joint venture Cummins, and it is not easy to evaporate, and its Autoignition temperature is lower than that of Cummins, so the formation and incineration method of combustible mixture are not the same as those of Sino US joint venture Cummins. The main difference is that the mixture in the cylinder of a diesel engine is compression ignition, rather than ignition. When the diesel generator set is running, the atmosphere enters the cylinder. When the air in the cylinder is compressed to the end point, the temperature can reach 500-700 ℃ and the pressure can reach 40-50 atmospheres. When the piston is close to TDC, the low pressure pump on the diesel engine radiates diesel oil into the cylinder at low pressure. The diesel oil forms fine oil particles, which are mixed with the atmosphere of high pressure and low temperature. The diesel oil inclusions extinguish themselves, shrink violently, and generate explosive force. The diesel generator set pushes the piston downward. At this time, the temperature can reach 1900-2000 degrees Celsius, and the pressure can reach 60-100 atmospheres, producing great power.
Fuel radiation control: Fuel radiation mainly includes: fuel supply (injection) quantity control, fuel supply (injection) timing, fuel supply (injection) speed and injection pressure control, etc.
Supercharging: The turbocharging control of the diesel engine of the diesel generator set is mainly completed by the ECU according to the diesel engine speed signal, load flag, boost pressure signal, etc., by controlling the opening of the wastegate or the emission angle of the exhaust injector, the turbocharger turbine exhaust gas inlet cross-section size and other methods, so as to improve the torque characteristics of the diesel engine and improve the acceleration performance, Remove emissions and noise.
Emission control: the diesel engine's emission is mainly exhaust gas regeneration (EGR). The diesel generator set ECU mainly controls the EGR valve opening according to the diesel engine speed and load flag, and the diesel generator set controls the EGR valve opening according to the memory method to adjust the EGR rate.
Start control: diesel engine start control of diesel generator set mainly includes oil supply (injection) quantity, oil supply (injection) timing control and preheating device control. In particular, oil supply (injection) quantity and oil supply (injection) timing are opposite to other working conditions.
Fault self diagnosis: the electronic control system of diesel generator set also includes two subsystems: fault self diagnosis and failure. When a malfunction occurs in the electronic control system of the diesel engine, the self diagnostic system will light up the "system fault light" on the dashboard, remind the driver to pay attention, and store the fault code. During the test, the system fault code and other information can be retrieved through a certain sequence of use; At the same time, if the system fails, the corresponding protection mode will be activated to ensure that the diesel can continue to run or stop.
