A new concept of diesel engine fuel injection system with DDVC hydraulic actuator

One of the most important subjects for the ship in recent years is to decrease the environmental impact by the exhaust from diesel engine. This research proposes a new composition of a simple, cheap, efficient fuel injection system by using the Direct Drive Volume Control actuator. It is well known that fuel injection pressure, injection timing and injection pattern has big influence for efficient combustion and this study shows the proposed injection system has availability to optimize those parameters.
