摘要:
A multicylinder internal combustion engine, which can simplify its control and is advantageous against thermal loads or vibrations includes a cylinder head with intake valves and exhaust valves arranged therein. Valve actuators are provided for openably operating the intake valves and exhaust valves, respectively. A cylinder head cover forms, in combination with the cylinder head, a valve actuator chamber with the valve actuators accommodated therein. At least some of the valve actuators are deactivatable to disable their corresponding cylinders. The multicylinder internal combustion engine is a V-shaped internal combustion engine provided with a front bank and rear bank. The cylinders on opposite ends in a direction of a crankshaft are set as full-time operating cylinders.

An air intake control system is provided for an internal combustion engine of a vehicle. The control system includes an intake port of a cylinder head for an engine main body, a throttle body having a throttle valve and connected to the intake port, an electric actuator having an electric motor and arranged on the throttle body to drive open or close the throttle valve, and a connector disposed on a housing of the electric actuator in a position facing toward one axial end of a crankshaft. The connector is provided in order to connect to an outside conductor to the electric motor of the electric actuator. The resulting configuration facilitates the work to connecting the outside conductor to the connector.

An operation amount detecting unit 17 detects an operation amount of a throttle grip from a zero position. A basic throttle opening degree computing unit 18 computes a basic throttle opening degree corresponding to the operation amount. A throttle opening degree additional value computing unit 20 outputs as a target throttle opening degree a value obtained by adding the basic throttle opening degree with a throttle opening degree additional value corresponding to the operation amount when the operation of the throttle grip is performed within a small operation region corresponding to an idle operation. The throttle opening degree additional value computing unit 20 outputs as the target throttle opening degree the basic throttle opening degree when the operation of the throttle grip is performed without the small operation region.
摘要:
An intake air control device is provided in which a throttle valve is fixed to a valve shaft which is rotatably supported within air intake path of an engine body. An actuator is connected to an end of the valve shaft to reduce the length of a throttle cable while simplifying the structure of a steering handle in the vicinity of the throttle grip. A vehicle body frame includes a head pipe at a front end, and a pair of main frames bifurcated from the head pipe to the left and right and toward the rear. A throttle operating amount detecting module, formed by mounting a throttle operating amount sensor to a storage box for storing a rotating member, which rotates in response to a throttle operation, is supported by one of the main frames in front of an air intake path forming body and arranged between the main frames.

An ignition timing controlling apparatus for an engine includes an ignition timing map in which high-torque timings are stored, an ECU for changing a high-torque timing obtained from the ignition timing map into a fuel-conserving ignition timing, and an advance angle target amount map in which advance angle target amounts with which the high-torque timing is to be changed into the fuel-conserving ignition timing are stored. The ECU is operable to calculate an advance angle target amount for each of cylinders of the engine based on the advance angle target amount map when a running state of a vehicle is in a cruize state in which little acceleration or deceleration is included, and also to execute advance angle control of changing the ignition timing of each of the cylinders stepwise with respect to the advance angle target amount for each of the cylinders.
摘要:
An intake air control device is provided in which a valve shaft extends in the left and right direction of a vehicle body frame across an air intake path, and is rotatably supported by an air intake path forming body connected to an engine body, equalizing the distances from a center of the vehicle body frame in the left and right direction to both ends of the intake air control device when arranging the air intake path forming body at the center of the vehicle body frame in the left and right direction. An actuator, which applies a motive power to drive the valve shaft, is connected to one end of the valve shaft, and a throttle operating amount sensor for detecting the throttle operating amount by a vehicle operator is supported by the air intake path forming body and connected to the other end of the valve shaft.
摘要:
A traction controlling apparatus is configured such that if a slip of a driving wheel is detected, then a throttle valve opening is reduced to a first predetermined value. If failure is detected while the throttle valve opening is reduced to the first predetermined value, then the throttle valve opening is further reduced to a second predetermined value. If the acceleration grip is manipulated to a fully closed position while the throttle valve opening is reduced to the second predetermined value, then the control is ended and throttle control by a direct manipulation of the acceleration grip is enabled.
