DME fuelled truck

Following the development work of the individual parts of the project the integration of all parts into the vehicle was performed at Volvo. This was done to integrate into the vehicle the complete engine with new fuel system, fuel supply system and electronics and solve integration related issues as they appeared. This work was successfully carried out and resulted in the final AFFORHD truck.

In particular the following subsystems were put together in the vehicle:
- The fuel tank and fuel supply lines with integration of the tubes for low-pressure transport of the fuel and the cooler.
- The injection system on the engine.
- The electrical harness according to new-implemented functions.
The work also included final de-bugging for tuning.

Following the integration part was tuning the overall system on the vehicle to reach drivability target while maintaining the same emissions and fuel consumption. The vehicle development work was mainly concentrated on emissions and start up strategies. Calibration activities were limited to that needed to reach emission and consumption objectives, and such that the field test could be conducted without problems.

The experimental part was dedicated to the precise evaluation of the behaviour of the vehicle developed for running on DME. In combination with the fine-tuning of the transient driving behaviour and the speed governing of the engine resulted in a representative vehicle for validating the DME technology.

The main part of the vehicle control hardware is standard Volvo equipment, which has been put through an Electro Magnetic Compatibility [EMC] test. As the complete vehicle has been finally tuned for field tests it will be put through an EMC test to avoid any problems during driving with the interference of electro-magnetic radiation.
