The all-mode engine crankshaft speed regulator is located in the camber of the high-pressure fuel pump housing and is driven by its cam shaft;
For every hour of operation, more than 800 m3 of air is sucked into the engine cylinders, which, especially in conditions of heavy dustiness, is clogged with many tiny grains of sand, which are stronger than steel in their hardness
To increase the liter power in the KamAZ-7403.10 engine, supercharging is used, i.e. air is supplied to the cylinders using a compressor under pressure 1.5-1.9 times higher than atmospheric
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 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
