Engine operating modes

Start. Regardless of the position of the accelerator pedal, but depending on the temperature, the engine receives a different amount of fuel when starting. From 600 min^-1 (depending on coolant temperature) You can adjust the speed with the accelerator pedal. The higher the coolant temperature, the less fuel is required to start.

idle mode. The crankshaft position sensor, depending on the speed, transmits signals to the control unit, which compares the set and current values \u200b\u200band regulates the amount of fuel supply.

Set RPM Mode. Its task is to prevent vibration during movement. At the same time, depending on the number of revolutions, the crankshaft position sensor regulates the smoothness of the fuel supply, thereby avoiding «disturbances» from changes in engine speed. The amount of fuel injected for each cylinder individually changes so much that it is again set «calm» engine operating mode. However, the idle speed remains constant.

Full load mode. Before the mechanically created maximum fuel supply, the amount of fuel injected is somewhat limited, which ensures smooth acceleration. The amount of fuel supply is also limited when the injection system is faulty (EDC lamp is on).

The engine goes to «spacing». In this mode, the control unit, receiving the appropriate signals, immediately stops the fuel supply.

Compressor control. At low engine speeds (less than 1100 min^-1) and the engine load is greater than 90%, the A/C compressor is briefly switched off to allow full power to be used for the payload. For normal operation of the compressor, up to 9 kW is required.
