Fuel-injected IC engine arrangement

摘要

The fuel injection system has a pressurised feed to an injection jet (10) at the end of an adjustable support (5). This varies the injection depth inside the cylinder as well as the rotational alignment of the jet. The jet position is controlled by a control system (15) and a servo drive. A common-rail pressurised fuel supply and a switching control provides the fuel pulses for each jet. The axial position of the jet is adjusted by the control system to give best efficiency coupled with lowest emission products. The spark plug position is also adjustable.
