摘要： Systems and methods for determining fuel delay in a fuel injected engine with cylinders that may be deactivated are presented. In one example, the fuel injection delay is determined via a cylinder firing schedule array when the cylinder firing schedule array is available. The fuel injection delay is determined via weighted average of a fuel injection delay of a present engine cycle and a fuel injection delay of a past engine cycle when the cylinder firing schedule array is not available.

摘要： A method and a system for control of a torque Tqdemand requested from an engine in a vehicle, wherein the engine provides a dynamic torque Tqfw in response to the torque Tqdemand. Control of the requested torque Tqdemand is performed such that the control provides a desired value Tqfw_req for the dynamic torque and/or a desired derivative Tqfw_req for the dynamic torque. This is achieved by basing the control on at least one current value Tqfw_pres for the dynamic torque, on one or several of the desired value Tqfw_req and the desired derivative Tqfw_req for the dynamic torque, and on a total delay time tdelay-total elapsing from determination of at least one parameter value, to when a change of the dynamic torque Tqfw based on the determined at least one parameter value, has been effected.

摘要： A fuel supply system adapted to supply fuel to an internal combustion engine has both a check valve and a purge valve disposed in a purge passage that extends from a canister to connect with an intake passage of the internal combustion engine. A controller estimates a pressure within an intermediate purge passage of the purge passage located between the check valve and the purge valve without relying on the use of a separate pressure detection device to provide information regarding the same.

摘要： The objective of the present invention is to provide an exhaust purification system that is capable of purifying exhaust gas during both lean and stoichiometric driving. The exhaust purification system is equipped with: a feedback-use identifier, which identifies parameter values such that the error between the output value from a LAF sensor and the estimated value for the LAF sensor output as obtained from a model equation is minimized; and a stoichiometric driving mode controller. The controller performs feedback control and thereby determines the fuel injection amount such that in the stoichiometric driving mode the equivalence ratio value as calculated from the parameters reaches a target value which is set such that a three-way purification reaction occurs in an under-engine catalyst. The identifier identifies the model parameters before feedback control is initiated by the controller.

The control apparatus that controls a supercharger includes an ECU.

摘要： A cylinder-inflow EGR gas amount is estimated, a misfire limit EGR gas amount is calculated on the basis of an engine operation state, and the misfire limit EGR gas amount is compared with the cylinder-inflow EGR gas amount to predict whether a misfire occurs. When the misfire is predicted, a misfire avoidance control is executed. Further, an actual misfire countermeasure effect amount in a case of the execution of the misfire avoidance control is calculated, and the actual misfire countermeasure effect amount is compared with a required misfire countermeasure effect amount to determine whether the misfire is avoidable when the misfire avoidance control is executed. If the misfire is unavoidable even if the misfire avoidance control is executed, a delay restriction value of an ignition timing to avoid the misfire is calculated, and the amount of a delay in the ignition timing is restricted using the delay restriction value.
