Abstract

An engine assembly includes a cylinder head having an intake side and an exhaust side opposite the intake side. The cylinder head has an intake port, an exhaust port, and a combustion chamber in fluid communication with the intake port and the exhaust port. The engine assembly further includes a port fuel injector coupled to the cylinder head. The port fuel injector is disposed closer to the exhaust side than to the intake side of the cylinder head. Further, the port fuel injector is fluid communication with the intake port to allow fuel to be injected directly into the intake port. The engine assembly further includes a direct fuel injector coupled to the cylinder head. The direct injector is in fluid communication with the combustion chamber to allow fuel to be injected directly into the combustion chamber.
