According to the ignition method, gas-diesel can be classified as a forced-ignition engine
In a gas-cylinder installation, when the engine is running in gas-diesel mode, the gas pressure decreases from 20 MPa to atmospheric, which is accompanied by its cooling
The high pressure reducer is designed to reduce the pressure of compressed gas to 0.95 ... 1.1 MPa by one-stage expansion; has a safety valve 12 (fig.1),
The solenoid valve is used to pass gas to the low pressure reducer when the engine is switched to gas-diesel mode
The reducer is used to reduce the pressure of the gas supplied to the dispenser and then to the mixer
The dispenser is mounted on the mixer body and is designed to regulate the supply of the required amount of gas to the mixer in various engine operating modes
The mixer is designed to prepare a gas-air mixture, regulate the gas supply and, ultimately, obtain a given crankshaft speed; represents a cylindrical body 2 (Fig. 1), in which a diffuser 1 is inserted
The KamAZ-7409.10 gas-diesel engine is equipped with model 335 high-pressure fuel pumps
The control drive of the regulator and gas dispenser includes a system of levers and rods driven from the pedal through shaft 1 (Fig. 1)
Maintenance of the Kamaz gas-diesel power supply system
During the operation of the car, you need to pay attention to deviations from the norm that appear in the engine operation: knocking, interruptions, loss of power, difficulty starting
All devices designed to start automobile engines at subzero ambient temperatures are divided into two types: devices. ensuring the start of a cold engine, and devices that provide it with pre-heating
Fuel is supplied to the burner under pressure in a finely atomized state
Fuel pressure is generated by a special pump
Pre-heater PZD-30 for KamAZ
The electrical equipment of the preheater is designed to perform the following functions: induction coil 2 (figure) with a transistor switch generates high voltage current
Possible malfunctions of the Kamaz heater
Failure of the heater and improper handling of it can cause a fire
The electric torch device (EFD) is designed to facilitate starting a cold engine at ambient temperatures down to -30 °C
Kamaz vehicle clutch
The transmission serves to transmit engine torque to the drive wheels and allows you to change the magnitude and direction of this torque in accordance with the driving conditions of the vehicle
