Abstract A compressed natural gas injection device with moving-coil electromagnetic linear actuator and mushroom type poppet valve was designed to supply a large-bore intake port injection type engine with sufficient fuel timely. The transient engine CFD model combined with the poppet valve's motion was established to research the effect of injection conditions on the mixing homogeneity in the intake port and cylinder. Computed penetration distances of impinging jet with different k-ε models and different wall functions are compared with measured results in the literature to validate the model. It was observed that the gas injection location and number of nozzle holes have a significant effect on mixing performance both in the intake port and cylinder.
