ME engine torque requirements - function - GF07.61-P-4015BK

ENGINE 113.967 in MODEL 219 

ENGINE 113.964 in MODEL 164.1 

ENGINE 113.971 in MODEL 251 

The function (torque interface) coordinates and prioritizes the requirements of all vehicle systems requiring torque. At the same time, the dynamics of the conversion for each requirement are established.

The engine torque is modified as follows:

• Increase or reduction of injected volume
• Early or late adjustment of the ignition angle (rapid)
• Combination of both options

If the injected volume is increased and the ignition angle simultaneously adjusted to "late", the engine torque first stays the same, but the option is available to rapidly achieve a subsequent torque increase by early adjustment of the ignition angle (torque reserve).

The following functions can require an engine torque:

• Driver preset
• Transmission control/protection
• ESP
• Cruise control
• Torque limitation, e.g. during startup
• Limitation of engine speed and max. speed
• Ancillary assemblies (e.g. refrigerant compressor)
• Functions such as idle speed control and deceleration fuel shutoff.

Implausible torque requests are recorded in the fault memory.
