The diesel power system serves to supply air and fuel to the engine cylinders
The filter is installed on the left side of the car on the frame and is designed to remove mechanical impurities and water from the fuel (Fig. 1)
The fine fuel filter is designed to remove from it the smallest mechanical particles that were not retained in the coarse filter;
The low pressure fuel pump is installed on the high pressure fuel pump (on the rear cover of the speed controller) and is designed to supply fuel from the tank through the coarse and fine filters to the high pressure pump
The injection pump supplies the injector of each cylinder with strictly dosed portions of fuel under high pressure in accordance with the operating procedure and the specified mode
The fuel injection advance clutch is used to ensure economical engine operation at various speeds
The nozzle is used to spray fuel in accordance with the shape and volume of the combustion chamber
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;
The fuel supply control drive (Fig. 1) consists of a pedal, rods, levers and transverse rollers
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
The exhaust system is designed to release exhaust gases into the atmosphere
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
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
