Experimental study and 3D modeling of the working process of a hydrogen engine running on a lean mixture

A 3D mathematical model for a hydrogen engine based on the Navier—Stokes transport equations in the Reynolds form is developed and verified. The influence of the crankshaft rotating frequency, excess air ratio and ignition timing on the engine performance is established. The expediency of operation of a hydrogen engine with external mixture formation and forced ignition on a lean combustible mixture is proved.
