摘要： A cylinder comprises a cylinder axis, a cylindrical wall, and an exhaust port defined in the wall. At least one central transfer port and at least two side transfer ports are defined in the wall. Each of the at least one central transfer port and each of the at least two side transfer ports has a transfer channel extending therefrom. For each of the at least one central transfer port, an angle about the cylinder axis between a center of the central transfer port and a center of the exhaust port is greater than 135° and less than or equal to 180°. For each of the at least two side transfer ports, an angle about the cylinder axis between a center of the side transfer port and the center of the exhaust port is less than or equal to 135°. Engines and cylinder blocks are also disclosed.

摘要： A marine outboard engine includes an internal combustion engine including at least one fuel injector; a fuel vapor separator including: a separator body, a fuel reservoir defined by the separator body, and a first fuel pump fluidly connected between the fuel reservoir and the fuel injector; a fuel tank; and a second fuel pump fluidly connected between the fuel tank and the fuel vapor separator. The fuel vapor separator includes a heat exchanger disposed in the separator body. The heat exchanger includes at least one fuel channel defined by the heat exchanger body, the at least one fuel channel including: an inlet adapted for receiving fuel from the engine, and an outlet fluidly communicating with the fuel reservoir; and at least one coolant channel defined by the heat exchanger body, the at least one fuel channel and the at least one coolant channel being in thermal communication.
