摘要：
A gaseous fuel rotary piston engine has a rotor housing and a rotor. A side housing of the rotor housing is provided with an air intake port for supplying air to working chambers defined in the rotor housing and a gaseous fuel port which is connected to a gaseous fuel source through a fuel supply passage and through which gaseous fuel is supplied to the working chambers. The air intake port is formed to open near the top dead center on the intake stroke and close after the bottom dead center on the intake stroke. The gaseous fuel port is formed to open near the opening time of the air intake port and close substantially at the middle of the compression stroke.
