Abstract
In a two cycle internal combustion engine (2), a fuel injection system is provided with a low profile compact intake manifold (22) mounted to the crankcase (8) by an adaptor plate (24) and defining an intake air flow path in a first direction (28) behind the manifold (22) through a gap between the manifold (22) and the crankcase (8) provided by the adaptor plate (24). Intake air then flows (32) into throttle bore passages (30) from behind the manifold and then reverses direction and flows through supply passages (34) having fuel injectors (38) and then into the crankcase (8). The passages share a common plenum (42) within the manifold. The fuel injectors (38), their electrical connectors (48) and a common rigid fuel supply rail (44) are all in the common plenum (42) entirely within the low profile manifold (22) and sealed from moisture and salt in a marine environment.
