摘要： An internal combustion engine includes fuel injectors which directly inject high pressure fuel into combustion chambers of the engine. Spark plugs are provided in the combustion chambers, a catalytic converter is provided in the middle of the exhaust pipe for purifying the exhaust, and a temperature sensor is provided for detecting the temperature of a catalyst of the catalytic converter. A control unit which receives as input the engine rotational speed, load, and the detection value of the catalyst temperature sensor controls the engine such that, when the temperature of the catalyst is lower than a predetermined target temperature, the fuel injectors inject additional fuel into the combustion chambers during at least one of the expansion stroke and the exhaust stroke to mix the fuel with the exhaust. Thereafter, the exhaust having the additional fuel mixed in is reignited upstream of the catalytic converter to heat the catalyst to the target temperature.

摘要： An engine comprising a fuel injector arranged on the inner wall of the cylinder in the vicinity of the intake valve. When the engine is operating under a heavy load, fuel is injected by the fuel injector during the intake stroke toward the rear face of the valve head of the intake valve. At this time, the injected fuel impinges upon the rear face of the valve head of the intake valve and is reflected thereon. Then, the injected fuel flows into the intake port.

摘要： A fuel injector (6) and spark plug (7) are arranged in a combustion chamber (5) of an internal combustion engine. By forming by stratification a self-ignitable preliminary air-fuel mixture in the combustion chamber (5), a spatial distribution is given to the density of the preliminary air-fuel mixture in the combustion chamber (5). Part of the preliminary air-fuel mixture formed in the combustion chamber (5) is ignited by the spark plug (7) to cause combustion by flame propagation, then the remaining preliminary air-fuel mixture is successively made to self-ignite and burn with a time lag. The ignition timing is set so that the ratio of the preliminary air-fuel mixture made to burn by self-ignition becomes more than a predetermined lower limit and less than a knocking generation limit.

摘要： A gasoline in a material fuel tank is separated into a high-RON fuel having a higher octane value than the material fuel and a low-RON fuel having a lower octane value than the material fuel, by a separator device equipped with a separation membrane. Using a fuel switching mechanism, one or both of the high-RON fuel and the low-RON fuel are supplied to the engine in accordance with the state of operation of the engine. As the octane value of a fuel can be changed in accordance with the engine operation state, the state of combustion in the engine improves, so that both an increase in engine output and an improvement in an exhaust property can be achieved.

摘要： A fuel pump is constructed of a pump casing, a rotating member and a reinforcing member. The pump casing internally forms a pump chamber, in which the rotating member is received, such that the rotating member rotates to pressurize fuel in the pump chamber. The reinforcing member reinforces the pump casing against fluidic force applied to the pump casing. The pump casing is formed of resin. The reinforcing member is insert-formed in the pump casing, so that the reinforcing member is at least partially embedded in the pump casing.
