摘要： An engine includes an intake variable valve mechanism and an exhaust variable valve mechanism. An ECU causes all intake valves in all cylinders to stop in a closed state by means of intake variable valve mechanism when performing a fuel-cut operation, including when the engine is stopped. The ECU causes at least one exhaust valve in all cylinders to stop in an open state by means of exhaust variable valve mechanism. When executing a fuel-cut operation, needless compression can be avoided by stopping the exhaust valves in an open state, while protecting a catalyst from deterioration caused by contact with intake air by stopping the intake valves in a closed state. The amount of oil consumption of the engine, and electric power consumption, vibrations and a tendency for spontaneous ignition to occur at cranking time can be improved.

摘要： A system or method for controlling a multiple cylinder internal combustion engine operable in a reduced displacement mode with at least one valve or cylinder selectively deactivated include monitoring valve operation by analyzing camshaft position to detect valve operation inconsistent with a current cylinder state (activated or deactivated) and controlling the engine in response to detecting the inconsistent operation. The camshaft position may be used to produce a surrogate signal indicative of intake/exhaust valve lift generated using camshaft sensor tooth deviation relative to an expected or reference tooth position for a corresponding crankshaft position and compared to a corresponding threshold. The surrogate signal indicative of valve lift may also be generated by pattern matching or correlation of one or more reference tooth position patterns to a measured or inferred tooth position pattern.

摘要： An internal combustion engine is provided with a fuel injector which injects fuel into an intake port and exhaust variable valve timing mechanism which changes a valve timing of an exhaust valve. A control device executes early exhaust valve closing control which advances a closing timing of an exhaust valve when conditions for executing early exhaust valve closing control stand. The control device detects an output torque output by an engine body. At the time of deceleration of the engine, even when the condition for executing early exhaust valve closing control stands, execution of early exhaust valve closing control is prohibited when it is predicted that the output torque will become smaller than the limit torque. Thus, due to execution of the early exhaust valve closing control, a large torque fluctuation is prevented from occurring at the time of deceleration of the engine.

摘要： In a method for diagnosing an internal combustion engine having first and second fuel injectors, if a misfire is detected, the following steps are performed in sequence: a first fuel quantity of the fuel is introduced only by the first fuel injector; a check is performed to determine whether a misfire results from the introduction of a first fuel quantity in the first step; a second fuel quantity of the fuel is introduced only by the second fuel injector; a check is performed to determine whether a misfire results from the introduction of the second fuel quantity in the third step; and an engine error is diagnosed if a misfire was detected in the second or in the fourth step.

摘要： A fuel separation apparatus comprises a stock fuel storage tank storing stock fuel, a separator provided with a separation film separating the stock fuel into high octane value fuel with an octane value higher than the stock fuel and a low octane value fuel with an octane value lower than the stock fuel, and a high octane value fuel storage tank storing the high octane value fuel separated by the separator. When the temperature of the separation film is lower than the high octane value fuel separation temperature, the high octane value fuel stored in the high octane value fuel storage tank is supplied to the separator. Due to this, vaporization of fuel is suppressed and the fuel can be quickly raised in temperature. Due to this, a vehicle mounted fuel separation apparatus able to quickly raise the temperature of the fuel supplied to the separation film so as to quickly raise the temperature of the separation film at the time of engine cold start can be provided.
