Abstract: An intake system of an internal combustion engine, in which a phase angle between throttle valves is provided in order to perform combustion appropriate for each cylinder so as to stabilize a number of revolutions and thereby suppress generation of unburned gas, is provided. The intake system is provided to intake passages of an internal combustion engine with parallel cylinders. The intake system includes a power transmission mechanism configured to transmit power from a power source to throttle shafts so as to synchronize and simultaneously turn a plurality of throttle valves and thereby open and close the intake passages. At least one of the throttle valves is an angled throttle valve having a phase angle at an open position relative to the other throttle valve.

Abstract: An electronic throttle body with an improved structure includes a throttle body. A plurality of vertically through airflow channels are provided on the throttle body, and a butterfly valve controlling a vent flow and a fuel atomizing ring configured to atomize fuel are arranged in each airflow channel. Centers of one or more butterfly valves are connected in series through rotating shafts to implement linked flipping, the rotating shafts are arranged parallel to each other, a drive gear is fixedly mounted to one end of each rotating shaft extending out of the throttle body coaxially, and the rotating shafts rotate synchronously through a servo driving apparatus. The servo driving apparatus and electrically controlled sprays respond synchronously, thereby improving the combustion efficiency of fuel in an engine. When the engine is idle, butterfly valves are directly driven through the servo driving apparatus to accurately control an air inflow of the engine.

Abstract: A control system for an internal combustion engine having a plurality of cylinders including first and second cylinder groups. The first and second intake systems correspond respectively to the first and second cylinder groups, and first and second throttle valves are provided respectively in the first and second intake systems. An output of the engine is reduced upon deceleration of a vehicle driven by the engine. A pressure parameter indicative of an assisting force generated by a brake booster is detected. An intake negative pressure is supplied to the brake booster from the first and second intake systems. One of the first and second throttle valves is opened to increase the engine output when the pressure parameter is equal to or less than a first threshold value which indicates that the assisting force of the brake booster has decreased.

Abstract: In an intake system comprising a first intake passage (1) having an upstream end communicating with an intake duct (3) and a downstream end communicating with an intake port of an engine cylinder, a first intake control valve (6) provided in the first intake passage, a second intake passage (2) having an upstream end communicating with the intake duct and a downstream end communicating with the intake port of the engine cylinder, a second intake control valve (7) provided in the second intake passage, an accelerator pedal (ACL) and a control unit (100) for controlling opening angles of the first and second intake control valves, the second intake control valve is opened when the first intake control valve has opened to an effective opening angle and an intake air flow rate is required to be further increased. The effective opening angle may be defined in a region where a change in the intake air flow rate of the first intake passage for a given change in the opening angle of the first intake control valve falls below a prescribed level. Thereby, as the accelerator pedal is depressed, a continuous increase in the intake air flow rate without involving a saturated region can be achieved.
