    Abstract: An engine controller according to one aspect of the invention is applied to a cylinder injection engine including a fuel injection valve that directly injects fuel into a cylinder. The engine controller determines whether knocking is occurring based on a signal from a knocking sensor. When the knocking is occurring, the engine controller performs partial lift fuel injection at a predetermined timing close to an ignition timing. The partial lift fuel injection is performed with a lift amount of a valve body of the fuel injection valve limited within a range between a minimum lift amount (0) and a partial lift amount, which is smaller than a maximum lift amount.

    Abstract: The invention relates to a control device applied to a cylinder injection type of the engine (10). The control device carries out a fuel injection while changing a penetration force of the injected fuel by changing a maximum value of a lift amount of the valve body (22) of the injector (20). Further, the control device controls an ignition timing on the basis of the engine operation state. The control device changes an end timing of a preceding injection carried out immediately before the ignition timing such that a time period between the end timing of the preceding injection and the ignition timing under a state where a first value is set as the maximum value of the valve body lift amount in the preceding injection, is longer than a time period between the end timing of the preceding injection and the ignition timing under a state that a second value larger than the first value is set as the maximum value of the valve body lift amount in the preceding injection.

    Abstract: An electric vehicle according to an example of the present application includes a battery, a regenerative brake, a friction brake, and a controller. The regenerative brake imparts regenerative braking torque to drive wheels. The friction brake imparts frictional braking torque to the drive wheels and non-drive wheels. The controller execute a slip control when the slip of the drive wheels is expected. The controller controls, during the execution of slip control, the regenerative and the friction brakes so that; the total of the frictional and the regenerative braking torque imparted to the drive wheels is less than or equal to upper limit torque set within a range that the drive wheels do not slip; the power of the regenerative power generation is not to exceed an acceptable charging power set according to a state of charge of the battery; and the regenerative braking torque is smaller than the regenerative braking torque before the start of the slip control.

    Abstract: An internal combustion engine has a plurality of cylinders and transmission arranged adjoining the engine. If designating an average height of a combustion chamber in a region inside from a virtual cylindrical surface passing through center of a valve body of an intake valve and extending in a circumferential direction of each cylinder when a piston is at top dead center, as “center height”, and designating average of a height of the combustion chamber in a region outside from the virtual cylindrical surface when the piston is at top dead center, as “peripheral height”, the combustion chambers form a center height of a transmission side cylinder positioned most to the transmission side among the plurality of cylinders is higher than center heights of usual cylinders including one cylinder other than the transmission side cylinder and a peripheral height at the transmission side cylinder lower than peripheral heights of usual cylinders.

    Abstract: A control apparatus for an internal combustion engine, wherein the internal combustion engine includes a fuel injection valve injecting fuel directly into a cylinder. The control apparatus includes an ECU. The ECU is configured to execute a divided injection control to inject fuel from the fuel injection valve by a plurality of partial lift injections. The ECU is configured to execute a division number reduction control when the value of a spray shape parameter representing spray shape fluctuation is greater than a division number reduction determination value. The division number reduction control is control to reduce the number of partial lift injections in one engine cycle and to lengthen an injection time of each of the partial lift injections.
