- step S 2 If the water temperature is lower than the predetermined threshold (hereinafter referred to as “cold state”), “Chin proceeds to step S 2 and if it is high (hereinafter referred to as“ warm state ”), “Chin goes to step S5.
- step S2 the controller 70 performs valve timing control using a conversion angle map for the cold TO state previously stored in the ROM! ⁇ .
- the conversion angle map for the cold prison takes the maximum conversion angle in the low rotation ⁇ range including the Idno l ⁇ ! S region, and the engine torque or engine rotation from the low rotation / low load range.
- the controller 70 is equipped with a map based on the engine speed detected by the crank angle sensor and the engine load detected by the accelerator opening sensor. The conversion angle is retrieved from, and this is set as the target conversion angle m .
- control is performed so that the valve timing retard amount of the exhaust valve increases in the vicinity of the sea shell area.

- the controller 70 prohibits the operation of the variable valve leakage 30 by switching the solenoid valve 40 to the gf fe action.
- step S6 the controller 70 determines whether there is an engine stop request as in step S3. If there is an engine stop request, Nototin proceeds to step S7, but no: ⁇ ends the process.
- step S7 the controller stops the engine without providing a delay time. If the engine is warm, the exhaust timing of the engine is sufficient, and the HC emission amount of the engine itself is small, so that the valve timing is fulfilled by HC ⁇ «in the exhaust gas. Ten percent is small. In other words, Idono! ⁇ ! ⁇ Even if prohibiting 3 ⁇ 4 valve lift in the S region has an effect on exhaust performance.
- the engine is requested to stop when the engine is idling in a warm state. For this reason, if the delay of the variable valve leakage 30 is allowed in a warm state and a delay time is provided from when the engine stop request is received until the engine is stopped, it is possible to give a feeling to the former. Increases nature.
- This control operates the variable valve ⁇ 30 in the ⁇ l ⁇ S region in the cold prison state, while prohibiting operation in the low rotation region including the idle avoidance region in the warm-up state, and requests to stop the engine.
- the engine stops after a delay time ⁇ , whereas in a warm state, the engine stops.
- valve timing in the initial state does not have to be an M angle valve, but a variable valve that can be controlled in the retarded direction, that is, a variable valve ## that can be set to a predetermined advance position You can use it.
- variable valve valve 3 ⁇ 4 ⁇ when the engine is restarted, the variable valve valve 3 ⁇ 4 ⁇ is in the most advanced angle state, so that combustion is stabilized immediately after the restart, and generation of abnormal noise can also be prevented.
- the exclusive power of this invention is claimed as follows.
