摘要： In an internal combustion engine of gasoline direct injection type, there is arranged a gasoline vapor purging system. The vapor purging system has a vapor purging section which temporarily traps gasoline vapor produced in a fuel supply section of the engine and feeds the gasoline vapor through a vapor purge conduit into an intake section of the engine upon operation of the engine. In the vapor purge conduit, there is installed an electrically actuated valve which controls the flow of the gasoline vapor toward the intake section. The vapor purging system has further a control unit which controls operation of the valve so that a target purging rate of the gasoline vapor toward the intake section is determined based on an amount of gasoline injected to each combustion chamber of the engine through an injector.

摘要： In a, so-called, lean burn engine having a vaporized fuel processor, a concentration of a vaporized fuel purged into an intake air passage (so-called, a purge concentration) is estimated using a normal type oxygen concentration sensor. Whenever a predetermined interval of time has passed, the engine combustion condition is forcefully and temporarily transferred into a stoichiometric air-fuel mixture ratio combustion condition during which the purge concentration is estimated on the basis of an output signal from the oxygen concentration sensor during an air-fuel mixture ratio feedback control.

摘要： An apparatus is provided for controlling an intake valve of a vehicular internal combustion engine. The apparatus includes a variable valve operating mechanism configured to vary a valve lift and a valve phase angle of the intake valve, and a controller. The controller calculates a desired first target value at a current engine operating condition, a reacceleration estimated value based on an engine rotational speed and estimated operating load upon reacceleration, and a second target value at which engine torque is equivalent to engine torque at the first target value. The controller sets the first target value as a control target value, and then switches the control target value to the second target value when a minimum clearance between the intake valve and a piston is determined to become less than a permissible value during variation of the intake valve from the first target value toward the reacceleration estimated value.

摘要： A throttle actuator varies an actual throttle valve opening degree for an engine in response to a control signal independently of driver's accelerator operation. An engine control unit determines a target torque (or a variable quantity representing the target torque) in accordance with an accelerator opening degree, and normally controls the actual throttle opening degree in a normal mode based on the target torque. In a predetermined operating region where the throttle opening responds too sensitively to a change in the target torque, the control unit controls the throttle opening degree in a constraint mode in accordance with a parameter, such as the accelerator opening degree, independent of the target torque.
