Natural gas fuel metering assembly and engine with same

摘要

A fuel metering assembly for a natural gas fuel engine having an engine block from a diesel engine with a diesel engine injector pump flange integrally cast as part of the engine block. The metering assembly has inlet and outlet manifolds for fuel and a plurality of fuel injectors therebetween. The manifolds are held in a fixed position relative to one another by a plate on one end that fits to the injector pump flange on the engine block to mount the metering assembly to the existing flange. In addition, the inlet manifold includes pressure and temperature sensors inside the inlet manifold to sense pressure and temperature at the point of metering.
