Urea-water injector module
A urea-water injector module is provided. The urea-water injector module includes an injector configured to discharge urea water to purify exhaust gas of a vehicle, a main body having the injector installed therein, and a plurality of heat dissipation plates stacked on an exterior surface of the main body to assist heat dissipation. Further the urea-water injector includes a heat block flange disposed under the heat dissipation plate and configured to obstruct heat from being transferred from an exhaust pipe and a mounting unit disposed under the heat block flange and coupled to the exhaust pipe.
VEHICLE POWER SYSTEM
A vehicle system for mounting in a vehicle which includes a control device. The control device includes a calculation unit calculating a stopping rate which is a percentage an automatic stop in a predetermined period, and a charge controller. The charge controller performs charging relative to an electrical storage device from a power generator when a charging rate is lower than a predetermined charging rate. The charge controller also controls the power generator such that the charging rate to the electrical storage device is increased with an automatic restart.
Control device for internal combustion engine
A control device for an internal combustion engine for a vehicle having: an internal combustion engine; and an electric motor connected to an output shaft of the internal combustion engine and applying torque to the output shaft by use of electric power supplied from storage batteries. The control device automatically stops the internal combustion engine when an automatic stop condition is satisfied. The control device disables automatic stop from being carried out when an automatic stop disabling condition is satisfied. And the control device decreases an output of the internal combustion engine and increases an output of the electric motor when the automatic stop condition of the internal combustion engine is disabled and when the automatic stop condition is satisfied but the automatic stop disabling condition is not satisfied.

Managing firing phase transitions
Methods and controllers for dynamically altering the phase of a firing sequence during operation of an engine are described. The described methods and controllers are particularly useful in conjunction with cylinder output level modulation operation of an engine such as dynamic skip fire operation of the engine and/or multi-charge level operation of the engine.

Methods and system for partial cylinder deactivation
Methods and systems are provided for reducing pumping losses during a partial deactivation. In one example, a method may include applying negative pressure to a deactivated cylinder group to remove gases trapped therein while an activated cylinder group continues to combust.
ENGINE CONTROL APPARATUS
An engine control apparatus determines that a piston is at a compression top dead center immediately before engine speed of an engine becomes zero if of the engine speed at the compression top dead center of the engine in a rotation drop period while the engine speed drops to zero after combustion of the engine is stopped. In the case where it is determined that the piston is at the compression top dead center immediately before the engine speed of the engine becomes zero, the engine control apparatus applies counter torque by the rotating electrical machine from the compression top dead center to stop the piston at a rotation angle position in a first half period of expansion process by application of the counter torque.
RESTART CONTROL SYSTEM
A restart control system includes a rotational angle estimation unit that estimates a rotating electrical machine's rotational angle in a state wherein an internal-combustion engine's rotational speed detected by a rotational speed detection unit is higher than an estimation threshold and configured not to estimate rotating electrical machine's rotational angle in a state wherein internal-combustion engine's rotational speed is lower than estimation threshold; a rotating electrical machine control unit increases internal-combustion engine's rotational speed by rotating electrical machine under condition where predetermined restart conditions are satisfied and rotating electrical machine's rotational angle is estimated by rotational angle estimation unit, thereby restarting the internal-combustion engine; and a starter motor control unit starts driving of a starter motor under a condition where predetermined restart conditions are satisfied and internal-combustion engine's rotational speed falls below a predetermined rotational speed set lower than estimation threshold, thereby increasing internal-combustion engine's rotational speed to estimation threshold.
VEHICLE CONTROL DEVICE
While a vehicle is coasting with an engine being automatically stopped and a power transmission path between the engine and wheels being disengaged, when a deceleration request is made and the engine is restarted with the power transmission path being engaged, a deceleration level increases relative to the deceleration level required by a driver or the vehicle, thereby lowering drivability. A vehicle control apparatus includes a deceleration level control unit that controls the deceleration level of the vehicle such that, during travelling of the vehicle continuing to travel with a power transmission mechanism between the engine and the wheels being disengaged, when the deceleration request is made and the engine is started by an engagement of the power transmission mechanism, the deceleration level becomes a target deceleration level calculated from a first target deceleration level generated after the engagement of the power transmission mechanism is complete and a second target deceleration level generated in response to the deceleration request.
