摘要： An internal combustion engine is equipped with an intake camshaft and a valve timing adjustment device. The intake camshaft has an intra-axial oil channel, and an outflow hole that causes hydraulic oil in the intra-axial oil channel to flow out toward an intake valve. The valve timing adjustment device discharges hydraulic oil to the intra-axial oil channel in changing the valve timing. A controller executes control for holding the valve timing when an execution condition including that idling operation of the internal combustion engine has continued for a predetermined time is not fulfilled, and executes fluctuation control for fluctuating the valve timing by controlling the valve timing adjustment device when the aforementioned execution condition is fulfilled.

摘要： To enable, with a simple control, a malfunction of a type wherein the output from a knock sensor becomes excessively large to be detected, a knock-sensor malfunction diagnosis device includes a control section configured to determine that knocking has occurred when the magnitude of a knocking vibration frequency component derived from an output signal from a knock sensor exceeds a first threshold value, and diagnose the knock sensor as malfunctioning when a prescribed diagnostic condition wherein knocking cannot occur is satisfied and the magnitude of the knocking vibration frequency component derived from the output signal from the knock sensor exceeds a second threshold value. The control section is further configured to determine that the diagnostic condition is satisfied for a time interval from a time when a predetermined time period has expired after fuel-cutoff has started to a time when the fuel-cutoff ends, during execution of the fuel-cutoff.

摘要： Methods are provided for rapid zero flow lubrication of a high pressure fuel pump, wherein a fuel rail pressure rapidly responds to commanded duty cycles. A method is needed to control operation of the high pressure pump during times when no direct injection is requested by an engine system and when operation of the high pressure pump is continued to maintain pump lubrication. To lubricate the high pressure pump while gaining zero flow rate data, methods are proposed that involve both open and closed loop control of the high pressure pump.

摘要： Methods and systems for engine control optimization are provided. One or more operating conditions of a vehicle engine are detected. A value for each of a plurality of engine control parameters is determined based on the detected one or more operating conditions of the vehicle engine. A range of the most commonly detected operating conditions of the vehicle engine is identified and a region of optimization is defined based on the range of the most commonly detected operating conditions of the vehicle engine.
