摘要： PROBLEM TO BE SOLVED: To materialize reduction of noise and vibration, and miniaturization of a rotary engine.
SOLUTION: A plurality of rotors 2a - 2d are stored in a common space enclosed by a rotor housing 1 and side housings 4a, 4b. Eccentric parts 3a - 3d rotatably supporting the rotors 2a - 2d interlock with an output shaft 3 while keeping eccentricity to the output shaft 3 and keeping a condition where inertia force in eccentric rotation of the rotor is balanced by the whole rotors 2a - 2d stored in the common housing. Consequently, dynamic unbalance caused by eccentric motion of the rotors 2a - 2d is suppressed and rotor intervals are shortened by just that much of omitting the side housings between the rotors 2a - 2d.

摘要： PROBLEM TO BE SOLVED: To improve the ignitability of an internal combustion engine employing gaseous fuel as main fuel.
SOLUTION: The internal combustion engine employing the gaseous fuel as the main fuel includes an ignition plug 140, a gas injection valve 32 for supplying the gaseous fuel to the engine, and a liquid injection valve 42 for injecting liquid fuel to the engine. An ECU 100 judges whether the ignitability obtained by the gaseous fuel is within an appropriate range or not. When the ECU 100 determines that the ignitability will exceed the appropriate range, the liquid fuel as auxiliary fuel for ignition is supplied to the engine in addition to the gaseous fuel. In the appropriate range of the ignitability, for example, a required discharge voltage of the ignition plug 140 is regarded as a reference. When the required discharge voltage actually exceeds a set discharge voltage of the ignition plug or when it is predicted based on required torque or the like that the required discharge voltage will exceed the set discharge voltage, the discharge voltage is lowered by employing both the gaseous fuel and the liquid fuel and the ignitability is improved by injecting the minimum amounts of the fuels.

摘要： PROBLEM TO BE SOLVED: To improve thermal efficiency of an internal combustion engine using reformed gas fuel as main fuel. SOLUTION: This engine is provided with at least reforming catalyst 230 reforming liquid fuel to gas fuel containing a plurality of gas components, an evaporator 220 for supplying gasified fuel to the reforming catalyst 230, a flow rate sensor 140 detecting flow rate of liquid fuel to the evaporator 220, and a catalyst temperature sensor 146 detecting reformed catalyst temperature. When liquid fuel is reformed by steam, water flow rate detection is also executed. An ECU 100 estimates reformed gas composition by using at least detection values of a flow rate sensor and a catalyst temperature sensor and referring a corresponding map of gas composition and a detection value stored inside. An estimated value is corrected according to measured specific gas composition concentration in the reformed gas and a detection value of temperature of input and output gas to and from the catalyst. The ECU 100 operates lean combustion limit concentration of air fuel mixture in a cylinder based on the estimated vale, and always materializes operation in a vicinity of lean combustion limit by controlling gas fuel supply quantity and air flow rate.
