Main use

The injection pump and engine control module are now integrated into one and the same unit. Accordingly it is not possible to replace just the control module for example, but the complete unit is changed. The new engine control module can store information in flash memory, which can be reprogrammed with SPS via Tech 2.

The advantage of having the engine control module mounted on the pump is that there is less cabling and communication between pump and control module works more quickly. This results in the engine control module reacting very quickly when it has received information from the different sensors. The control module is manufactured to withstand vibrations, temperature and other outer influences better than the previous control module. The control module determines the maximum permitted fuel quantity per combustion, guided by preprogrammed limiting values and values from the different sensors. At the same time as this is taking place, a suitable time point is determined for starting the pressure build-up in the diesel pump. The control module, which is mounted on the diesel pump, has two 56-pin connections. One connection on each side of the control module.
