Abstract

As one of key components in a common rail fuel injection system, a solenoid valve is used as an execution unit in controlling fuel injection amount, injection timing, injection duration and injection rate, which has a decisive impact on the performance of the common rail fuel injection system, AMESim simulation model of marine low-speed fuel injection system is built and the experimental data were used to verify and optimize the experiment, the simulation model showed that using self-developed fuel injection control valve can achieve multi-injection performance of marine low speed engine, The minimum time of single injection is 1.2ms, the minimum interval between two injections is 1.9ms.
