Air Fuel Ratio Controller of Jichai Diesel Generator Set

In recent years, a new type of air-fuel ratio controller has been used in the turbocharged diesel engine of Jichai diesel generator set, which can supply oil reasonably at any time according to the amount of air entering the cylinder, replacing the vacuum air-fuel ratio controller controlled by the fuel switch in the early days and the transfer of residual oil. The air-fuel ratio controller of JICHAI diesel generator set is installed between the PT pump throttle valve and the fuel cut-off valve. In the PTG-AFC fuel pump of JICHAI diesel generator set, the fuel of JICHAI diesel generator set leaves the throttle valve and passes through the AFC device, then reaches the fuel cut-off valve on the top of the pump body of JICHAI diesel generator set.

After the turbocharging of JICHAI diesel generator set, the fuel supply of the fuel injection pump of JICHAI diesel generator set increases, so that the air entering the cylinder of JICHAI diesel generator set can not keep up with the rapid increase of fuel supply under low speed, heavy load or acceleration conditions, resulting in incomplete combustion of JICHAI diesel generator set and easy to appear black smoke.

Fuel oil flows out of the governor of Jichai diesel generator set and enters AFC through throttle valve. When the turbocharger of Jichai diesel generator set does not provide air pressure, the plunger is in the upper position, and the main fuel flow circuit of Jichai diesel generator set is closed. The control valve of Jichai diesel generator set is directly installed in the second channel controlled by the throttle position to supply fuel oil for Jichai diesel generator set. When there is no inflation, the control valve of JICHAI diesel generator set is directly installed on the upper side of the throttle shaft in the throttle cover plate.
