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.

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. Additionally, a hydrogen engine is connected to a hydrogen discharging tank containing a hydrogen storage alloy by way of a heating medium passage and a hydrogen supply passage. A pressure tank is provided in the hydrogen supply passage. A control means for limiting the starting of the engine until the pressure of the hydrogen gas in the pressure tank reaches a predetermined value is provided on the engine. When the engine is to be started, a heating medium in the heating medium passage heats the hydrogen discharging tank to discharge hydrogen gas therefrom. The discharged hydrogen gas is supplied to the pressure tank to increase the pressure of the hydrogen gas in the tank. The control means detects the pressure to limit the start of the engine until the pressure reaches the predetermined value.
