The engine is of conventional mechanical design, optimized for this particular application. Lightweight reciprocating components give minimum vibration and reliability is assured by good design, high duty materials and advanced manufacturing techniques.

A deliberate decision was taken to use mechanically controlled fuel injection for the current engine, employing a purpose-designed injection pump. For the future, electronic control will allow further enhancements in performance. The engine is capable of operation on either diesel fuel (mineral and bio-diesel) or aviation kerosene.

The result is a simple, compact, lightweight power unit of more than twice the specific power output of conventional small diesel engines.

The usable engine speed range is also much greater than other diesel engines. Peak power of some 50 hp/litre is developed at around 5800 rev/min, with usable power available up to well over 6000 rev/min. This is combined with excellent low speed torque in a way which is unique for a diesel engine. The motorcycle thus has outstanding drivability with less need for gearchanging, which aids both on-road enjoyment and cross-country performance in the hands of expert and less experienced riders alike.

The technology is immediately transferable to
other applications requiring small, lightweight,
high speed diesel engines.
