摘要： Disclosed herein is a device for controlling a vehicle engine by controlling a throttle valve by the drive-by-wire method. Using the fact that an acceleration is proportional to an excess torque, a target torque is determined in accordance with a predetermined functional equation by using as input information a target acceleration determined based on the degree of operation of a man-controlled member, the current running acceleration and the current output torque. A target throttle opening rate is set further from the target torque. The throttle valve is then controlled to achieve the target throttle opening rate to predictably control the acceleration, whereby high-accuracy engine control is materialized and drivability is improved.

摘要： An NOx sensor 27 detects the concentration of NOx released from an occlusion type NOx catalyst 25 into the atmosphere. Based on the output of the NOx sensor 27, a total NOx discharge A is computed. When the total NOx discharge A reaches an NOx emission judgment amount A0, corresponding to an NOx emission judgment amount designated by NOx emission regulations, before a distance traveled C reaches a predetermined distance traveled C0, an exhaust air-fuel ratio is changed to a rich air-fuel ratio to release NOx from the occlusion type NOx catalyst 25 efficiently. Then, the exhaust air-fuel ratio is changed to a stoichiometric air-fuel ratio to purify and reduce NOx by a three-way catalyst function.

摘要： A running control method and a running control system for a vehicle to control the engine output according to the effects of slope, wind, and change in vehicle weight, in which a reference traction force is determined as the sum of a mechanism friction, an acceleration force, and an air drag, the difference between an actually measured total traction force an the reference traction force is determined to obtain an environmental effect value. The environmental effect value represents an increase or decrease in traction force with respect to that in a flat, windless road for a standard vehicle weight. A throttle valve or a fuel injection control governer is feedback-controlled according to the environmental effect value, thereby improving the control response.

摘要： An engine cooling device comprises an oil jacket surrounding a cylinder portion of an engine, an oil gallery supplying high-pressure oil to various parts of the engine, and an oil pressure regulator disposed between the oil jacket and the oil gallery to reduce the pressure of the high-pressure oil supplied from the oil gallery and to supply the oil at a reduced pressure to the oil jacket. Thus, the required mechanical strength of the oil jacket can be decreased to decrease the weight of the engine cylinder block.

摘要： An in-cylinder injection type internal combustion engine, which includes a main fuel injection control unit that drives a fuel injector to inject fuel directly into a combustion chamber, is provided so that premixed combustion or stratified charge combustion takes place depending upon operating conditions of the engine. The engine further includes an additional fuel injection control unit that drives the fuel injector to inject additional fuel during an expansion stroke after the fuel injector is driven by the main fuel injection control unit, when it is necessary to increase the temperature of a catalyst provided in an exhaust passage for purifying exhaust gas. An exhaust manifold includes an exhaust chamber, in which the exhaust gas remains, and the additional fuel that is left unburned is re-burned in the exhaust chamber.

摘要： An exhaust gas purifying apparatus, which is intended to improve hydrocarbon purifying performance and simplify the after-treatment of adsorbed hydrocarbon, an in which a three way valve 51 is operated under the control of a controller 80 to cause a bypass exhaust gas passage 30 to be communicated with a main exhaust gas passage, so that hydrocarbon in exhaust gas is adsorbed onto an adsorption catalyst 40 when the temperature of a three way catalyst 20 in the main exhaust gas passage 13 is low. When the three way catalyst temperature increases, the bypass exhaust gas passage is shut off from the main exhaust gas passage by the three way valve and the adsorption catalyst is heated by a heater 60, so that the adsorbed hydrocarbon is oxidized at the adsorption catalyst to form a harmless substance.
