First Claim
1. An intake apparatus of an internal combustion engine for a vehicle comprising:
- a duct for taking into a wind during a running of a vehicle;
an air cleaner operatively connected to the duct;
a fuel supply device for injecting a fuel into an intake air coming from the air cleaner;
a movable valve arranged between an outlet port of the duct and an inlet port of the air cleaner;
a negative-pressure motor for driving the movable valve; and
an electronic control unit for controlling the movable valve, said electronic control unit being connected to an ignition means,wherein said electronic control unit controls the opening and closing of the movable valve in accordance with a rotational speed of an internal combustion engine, an opening degree of a throttle of the engine and a gear position of the engine as control parameters and carries out a delay angular control of an ignition timing in response to the opening and closing control of the movable valve.
