摘要： Disclosed is a device for calculating an amount of an air introduced to a cylinder of an engine. An air-intake passage introduces the air to the cylinder. An air-exhaust passage exhausts gas from the cylinder. Both passages respectively have an intake valve and an exhaust valve. Both valves are respectively driven by an intake valve drive mechanism and an exhaust valve drive mechanism in accordance with a rotation of a crank shaft to alternatively and selectively open and close, and simultaneously open during a valve overlap period to open the passages to the cylinder. A variable valve timing mechanism controls an operational timing of the valve drive mechanisms with respect to the crank shaft in accordance with a running condition of the engine to vary a timing of the valve driven by the valve drive mechanisms. The calculating device comprises a first detecting device, which detects a rotational speed of the crank shaft. A second detecting device detects an intake pressure in the air-intake passage. A third detecting device detects the operational timing of the valve drive mechanisms. A calculating device calculates a displacement of the operational timing according to the detected rotational speed of the crank shaft and the detected operational timing. A first computing device computes the amount of the air introduced to the cylinder in response to the rotational speed of the crank shaft, the intake pressure, and the displacement of the operational timing.

摘要： A valve timing control apparatus that adjusts valve overlap by altering valve timing according to the running condition of the engine. A variable valve timing mechanism (VVT) alters the valve timing of intake valves to adjust the valve overlap. An electronic control unit (ECU) controls the VVT with respect to a target value calculated in accordance to the running condition of the engine to obtain the optimum valve overlap. The ECU controls the VVT to eliminate valve overlap under low temperature conditions. The ECU controls the VVT to switch from a state of nonexistent valve overlap to a valve overlap state as the temperature changes from a low temperature to a higher temperature. The ECU judges whether the engine is in a low temperature condition based on a predetermined reference value to suppress the difference in the amount of fuel (port wet amount) adhered to the intake port before and after the shifting of the state the valve overlap.

摘要： A fuel injection amount control apparatus for an engine comprises injectors for injecting fuel to an engine and an electronic control unit (ECU) for controlling the injectors. The ECU learns the deviation between the air-fuel ratio of a flammable mixture to be supplied to the engine and the target value. The ECU controls the amount of fuel injection to the engine by reflecting the learning value on the computation of the injection amount. The engine has intake valves, exhaust valves and an apparatus for altering the open/close characteristics of the intake valves. The ECU computes the learning value of the air-fuel ratio in accordance with the behavior of the characteristic altering apparatus and the running conditions of the engine. When the coolant temperature of the engine is low and the learning value is not renewed, the ECU compensates the already updated learning value to a smaller value. The ECU performs this compensation based on the ratio of the real valve characteristic to the valve characteristic for the engine in a fully warmed-up state.

摘要： A method for controlling fuel injection rate in internal combustion engine in accordance with the intake pressure and the engine speed. The method has the steps of determining the intake pressure using, as a variable, the period of time after a change in the throttle opening, and computing a basic fuel injection period on the basis of the thus computed intake pressure and the engine speed. The fuel injection is conducted by a system in accordance with this method. The system determines the intake pressure in the steady state of engine operation in accordance with the throttle opening and the fuel injection rate, effects a correction on the thus determined intake pressure so as to take into account a delay in response of the intake pressure to the transient period, and determines the basic fuel injection period on the basis of the corrected intake pressure and the engine speed. With this method and system, the fuel injection rate can be controlled in a high degree of conformity with the injection rate demanded by the engine, because the injection rate is determined on the basis of the engine speed and the actual intake pressure which can be predicted with a high degree of precision.

摘要： A first parameter correlated with a degree of fluctuation of output from an air-fuel ratio sensor is calculated, and whether or not the calculated first parameter has a value between a predetermined primary determination upper-limit value α1H and a primary determination lower-limit value is determined. Such forced active control as reduces an air-fuel ratio shift in one of the cylinders which is subjected to a most significant air-fuel ratio shift is performed when the calculated first parameter is determined to have a value between the predetermined primary determination upper-limit value and the primary determination lower-limit value. A first parameter is calculated while the forced active control is in execution. The calculated first parameter is compared with a predetermined secondary determination value to determine whether or not variation abnormality is present.

摘要： A fuel vapor treating mechanism includes a canister for adsorbing fuel vapor produced in a fuel feed system. The treating mechanism purges the fuel vapor adsorbed by the canister, along with air, to an intake system of the engine. An ECU computes a value representing the flow rate of the purged gas as a value that represents the capability of the treating apparatus. The ECU sets a decision value in accordance with the amount of the fuel vapor produced in the fuel feed system. The decision value represents a required capability of the treating mechanism. When the value representing the capability is less than the decision value, the ECU prohibits stratified charge combustion and causes the engine to perform homogeneous charge combustion. Therefore, as many opportunities as possible are provided to perform stratified charge combustion, which improves fuel efficiency.

摘要： A direct-fuel-injection-type internal combustion engine is equipped with an injector for injecting fuel directly into a combustion chamber of a cylinder. A controller controls the degree of opening of a throttle valve for adjusting the amount of air drawn into the combustion chamber and sets the throttle valve to a closed valve state by setting the degree of opening of the throttle valve to a degree of opening that is on the closed valve side of a post-engine start target degree of opening, when the engine is to be started. After it is determined that a start of the engine has been accomplished, the controller opens the throttle valve by gradually increasing the degree of opening of the throttle valve from the degree of opening of the closed valve state to the post-engine start target degree of opening.

摘要： The technique of the present invention reduces or even omits potential shocks and vibrations arising due to the coupling action of a coupling mechanism at the time of starting an internal combustion engine, and ensures a quick restart of the internal combustion engine. In a vehicle with an idling stop control apparatus of the present invention mounted thereon, a control unit inputs an inverted phase current Eon, which is determined according to the energy absorbing state of a transmission belt, into an auxiliary machinery driving electric motor, so as to brake rotations of the auxiliary machinery driving electric motor. After the input of the inverted phase current Eon into the auxiliary machinery driving electric motor, the control unit couples an electromagnetic clutch to link a crankshaft of the internal combustion engine with the auxiliary machinery driving electric motor. The value of the inverted phase current Eon is varied according to the energy absorbing state of the transmission belt. The braking force of the auxiliary machinery driving electric motor is thus varied according to the energy absorbing state of the transmission belt.

摘要： An improved apparatus is provided to control supply of airflow to an engine. The engine includes a combustion chamber connected to an air intake passage and an air exhaust passage. An air intake valve selectively opens and closes the intake passage to control the supply of the airflow to the combustion chamber. An air exhaust valve selectively opens and closes the exhaust passage to control the discharge of the exhaust gas from the combustion chamber. An altering device alters a period of an overlap of the valves by changing a valve timing of valves. A first detector detects a driving state of the engine. An ECU computes a target valve timing based on the detected driving state of the engine controls the altering device based on the computed target valve timing. An adjusting device is arranged in the intake passage to adjust the supply of the airflow to the combustion chamber. The ECU computes a target amount of the airflow to be supplied to the engine in an idling state. The ECU detects the period of the valve overlap. The ECU computes a correction value to correct the target amount of the air based on the detected period of the valve overlap. The correction value is continuously variable based on the period of the valve overlap. The ECU corrects the target amount based on the correction value by increasing the target amount by the correction value and controls the adjusting means based on the corrected target amount.
