Fundamentals of fuel properties influences for diesel PCCI & HMCCI combustion

Investigations made during Space Light project have shown that for PCCI combustion a fuel, in order to suit the needs of homogeneous combustion should meet the following characteristics:

- Fast vaporisation.
- Self-ignition features.
- Low aromatic content.
- Ability to be injected at high pressures.

This will ensure a good homogeneity of mixture and an almost simultaneous burn begin in the whole burning chamber.

Such a fuel must be newly developed that is why a closed co-operation between automotive and fuel industry is required. During SPACE LIGHT the first steps were already made in that direction.

The results obtained during this project have shown that there is potential for the development of HIMCCI even with actual fuels, that is however in a limited engine range. By using new developed fuels this range can be increased and eventually extended to the whole engine range when using also appropriate injection strategies and fully variable valve timing.

In the coming years, attention should be given to transient engine conditions and also in car tests, with a suitable fuel.

The availability of a fully variable timing system suitable for in-car test will ease the development of such burning processes.

Costs for this system should be in an acceptable range and they hang up on the whole system complexity. When such a system combined with an HIMCCI burning process will be cheaper to implement as the traditional after treatment system.
