    摘要: An upper limit guard is set for a valve overlap amount according to a KCS learning value used to retard-correct an ignition timing in order to suppress knock, and an engine load. As a result, it is possible to make the upper limit guard value a value able to restrict the valve overlap amount to a value equal to, or less than, a value at which an internal EGR amount does not become excessive during a retard-correction of the ignition timing. By applying the upper limit guard to the valve overlap amount using the upper limit guard value, it is possible to suppress the valve overlap amount from increasing from the optimum value following a retard-correction of the ignition timing, as well as suppress the value of overlap amount from being reduced when it is not deviating from the optimum value and is below the upper limit guard value.

    摘要: The apparatus of the present invention corrects a control target value of ignition timing using a multipoint learned value AGdp(n) for compensating for a change amount of the ignition timing caused by time-dependent change of the engine and a basic learned value AG(i) for compensating for a change amount of the ignition timing caused by a factor other than the aforementioned time-dependent change of the engine. In a multipoint learning range n in which the time-dependent change of the engine influences the ignition timing to a great extent, the control target is corrected using the multipoint learned value AGdp(n) and the basic learned value AG(i). In ranges other than the multipoint learning range n, the control target is corrected using only the basic learned value AG(i). Normally, only the learning of the multipoint learned value AGdp(n) is permitted in the multipoint learning range n, and only the learning of the basic learned value AG(i) is permitted in the ranges other than the multipoint learning range n. When it is determined that there is a possibility that fuel has been fed to a fuel tank, the learning of the multipoint learned value AGdp(n) is prohibited for a subsequent predetermined period (if NO in step S103 or step S104).

    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 temperature reduction control for reducing the temperature of an injector is performed through first to third fuel supply control routines executed by an electronic control device. When the temperature of the injector is reduced by the execution of the temperature reduction control, heat transfer to the vicinity of the nozzle of the injector is reduced. Since the vicinity of the nozzle of the injector is less likely to be placed in a high-temperature environment by in accordance with reduction in heat transfer to the vicinity of the nozzle of the injector, the formation of deposit around the nozzle of the injector is suppressed.
