AN INJECTOR EMULATION DEVICE

摘要

An injector emulation device for incorporation into a multiple fuel engine control system including a first control device (4) configured to operate a plurality of fuel injectors (10) to inject a first fuel into selected cylinders (8) of the engine (6) when the system is operating on the first fuel only and a second control device (54) arranged to operate, instead of the first control device (4), said plurality of injectors (10) to inject said first fuel when the system operates in multifuel mode, said first control device being connected to an injector emulation device for operation during said multifuel mode. The injector emulation device includes an electrical load device (157) arranged to mimic the electrical load characteristic of the injector (10) being emulated and further including electronic means which mimic the inductance and flyback characteristics of the injector (10) being emulated.
