摘要： PROBLEM TO BE SOLVED: To provide a fuel injection system having a simple construction for achieving fuel injection with high control accuracy even when vapor occurs. SOLUTION: The fuel injection system comprises a liquid phase LPG supply system 31 for supplying liquefied fuel gas stored in a fuel tank 30 to a liquid spray injector 21 in a liquid phase condition, and a gas phase LPG supply system 32A for supplying the liquefied fuel gas stored in the fuel tank 30 to a gas phase fuel injection means 22B in a gas phase condition. On the midway of a gas phase LPG supply pipe 320 as part of the gas phase LPG supply system 32A, a relief valve 321 is provided where a direction from the side of the fuel tank 30 toward the side of the gas phase fuel injection means 22B is set as a forward direction. An ECU 6 selects the opening/closing of the liquid spray injector 21 and the gas phase fuel injection means 22B, and uses the gas phase fuel injection means 22B for correcting injection during the injection of the liquid injector 21 at starting.

摘要： PURPOSE:To prevent inefficiency of fuel expenditure in a supercharger possible to set in two stages of high and low supercharging pressures, by making it possible to convert the supercharging pressure to the low pressure side automatically when the engine does not require a high torque for a partial loading, even though the supercharging pressure is set manually to the high pressure side. CONSTITUTION:In the above-captioned device, a waste gate valve 13 installed at an exhaust bypass route 22 furnished to detour a turbine 2 of a supercharger 1, is controlled by a diaphragm type actuator 14. In this case, a transformer room 16 for the actuator 14 is connected to an intake pipe 6 at the lower stream of a compressor 3 through a bypass route 12, as well as connected to a negative pressure control valve 19 convertible to link or cutoff to the atmosphere. The negative pressure control valve 19 is controlled by an ECU 26 according to outputs of a pressure sensor 25 and a manual switch 27. When the pressure in the intake pipe detected by the pressure sensor 25 is less than a preset value, for example, the valve 19 is off, the rightward movement of the diaphragm 15 is allowed, and the supercharger 1 can be converted to a low supercharging pressure condition.

摘要： PROBLEM TO BE SOLVED: To provide simple constitution to perform the injection of fuel with high metering precision even during the generation of vapor. SOLUTION: An ECU 6 decides the generating state of vaporized fuel in a liquid injection injector 21 to perform injection of fuel in a liquid phase based on the detecting signals of a fuel pressure sensor 72 and a cooling water temperature sensor 75. A gas injection injector 22 to decide the generation state of vaporized fuel in a liquid injection injector 21 to effect fuel injection in a liquid phase and perform liquid injection in a gaseous phase according to the degree of the generation of vaporized fuel is caused to effect assist injection. Shortage in fuel due to injection of fuel in a gas liquid mixing state by the liquid injection injector 21 is prevented from occurring.

摘要： PURPOSE:To enable such a control that the air-fuel ratio becomes larger at a maximum shift stage without detecting a shift stage which is actually set. CONSTITUTION:An air-fuel ratio control device for a vehicle incorporating an internal combustion engine 1 which can change the air-fuel ratio so as to set the same to any of several output characteristics, and an automatic transmission which sets the regulating pressure level of engaging hydraulic pressure fed to a frictionally engine device 2 in accordance with a maximum output characteristic of the internal combustion engine 1, hydraulic pressure detecting means 4 for detecting a hydraulic pressure which is generated only when the transmission being set to a maximum shift stage, and air-fuel ratio setting means 5 for setting the air fuel ratio of the engine 1 to a value with which an output power characteristic is lower than a maximum output power characteristic, when the hydraulic pressure detecting means 4 detects a hydraulic pressure.

摘要： PURPOSE:To perform such a control that the air-fuel ratio is enlarged only at the maximum speed position without sensing the shift position set actually. CONSTITUTION:A max. speed position admissible region setting means 4 decides the region where the setting prohibition of the max. speed position of an automatic transmission 3 is disengaged on the basis of at least two parameters, the load of an internal combustion engine 1 and the revolving speed of a certain rotary member, while a running condition judging means 5 judges that the running condition decided upon the two parameters lies within the region where the setting prohibition of the maximum speed position is disengaged, and an air-fuel ratio setting means 6 sets the air-fuel ratio of the internal combustion engine 1 to a value presenting a lower output characteristic than the maximum in case the passed judgement is such that the running condition has entered the region where the setting prohibition of the max. speed position is disengaged.
