Abstract: Introduction of a low fuel consumption technique such as downsizing turbos and idling stop decreases an intake pipe negative pressure (pump loss) of an internal combustion engine, and results in difficulty in emitting (evaporative fuel purge) a volatile fuel (volatile fuel) in a fuel tank by the negative pressure of the intake pipe of the internal combustion engine.
A control device includes: a purge control unit which controls a purge valve which emits a volatile fuel of a fuel tank or a canister to an intake pipe of an internal combustion engine; and a power transmission control unit which controls a power transmission mechanism between the internal combustion engine and a drive wheel, and, in a state where the power transmission control unit disconnects a clutch, and the vehicle is coasting, the purge control unit opens the evaporative fuel valve and purges an evaporative fuel to the intake pipe.

Abstract: There is provided a vehicle-mounted control device that, when a restart request is generated during a time interval between the fulfillment of an engine automatic stop condition and complete stop, decreases a charging efficiency of an engine by means of at least one of a throttle valve and an intake valve to prevent an increase in the reverse rotational frequency of the engine, thereby ensuring the durability of the starting device of the engine, and preventing an accelerator response from deteriorating when a restart request based on the accelerator operation is generated. In the vehicle-mounted control device that controls a charging efficiency of the engine on the basis of the requested engine output amount, the engine is automatically stopped when a predetermined automatic stop condition is fulfilled, and a charging efficiency at the time when a restart condition of the engine has been fulfilled on the basis of an engine output request generated during a time interval between the fulfillment of the automatic stop condition and complete stop of the engine is made lower than a charging efficiency for the requested engine output amount.

Abstract: An object is to provide a type of device capable of properly cooling a bearing of a throttle body even under a condition that the throttle body receives heat of high-temperature intake air or exhaust gas.
In the present invention, an engine coolant passage that guides a coolant of an engine is provided integrally with a member fixing a bearing to be adjacent to a circumferential wall of the bearing of the member fixing the bearing, which supports a throttle shaft, and heat transferred from the bearing (or likely to be transferred to the bearing) via the member fixing the bearing is carried away to the outside of a throttle body by the engine coolant.

Abstract: An object of this disclosure is to provide a fuel injection device that can reliably detect an operation timing of a valve body, that is, a valve opening timing with high accuracy. The current of an electromagnetic valve reaches I2 at time t3, an FET 201 and an FET 221 are turned on, and a battery voltage VB is applied to the electromagnetic valve until time t5 is reached. The amount of displacement of the valve body reaches a target amount of control lift at time t4 between time t3 and time t5, that is, a movable core 304 comes into contact with a fixed core 301. The detection of the valve opening timing is performed during the period from time t3 to time t5.

Abstract: Provided is an engine control apparatus capable of detecting degradation in particulate filter performance. An input unit receives a first signal indicating an exhaust gas state (dpf_2) inside or downstream of a particulate filter that traps particulate substance contained in engine exhaust gas. A determination unit 16a determines whether the particulate filter is degraded on the basis of the exhaust gas state (Tpf_2) indicated by the first signal in a period (fFC = 1) in which fuel supply to the engine is blocked.
