Fuel Injection Rate

Fuel injection rate shaping is one way to improve fuel efficiency and reduce harmful emissions in IC engines. Piezoelectrically actuated fuel injectors have a particularly fast response, which makes them capable of rate shaping operation. In this paper, a model-based closed-loop controller is designed to control the fuel injection rate passing through the nozzle of a piezoelectric fuel injector, by compensating for the injector’s nonlinear behavior. The performance of this controller is verified with simulation results.
