Abstract: A control system of a hybrid vehicle includes an internal combustion engine loaded on a vehicle, an electric motor loaded on the vehicle, and connected to wheels via a power transmission mechanism, a battery storing power that drives the electric motor, and a control device that controls engine torque generated by the internal combustion engine, and motor torque transmitted to the wheels by the electric motor. The control device calculates an outputable power of the battery based on a temperature and a state of charge of the battery. The control device is configured to make a torque change amount of the engine torque larger when the calculated outputable power belongs to a predetermined low power region than when the outputable power belongs to a high power region with higher power than the low power region.

Abstract: A control system for a hybrid vehicle configured to reduce an exhaust gas during deceleration of the vehicle, and to protect a motor and a battery. A control mode of the engine may be selected from: a low-power mode in which the hybrid vehicle is decelerated by reducing a torque and a power of the engine at a predetermined rate while generating the brake torque by the motor; and a high-power mode in which the hybrid vehicle is decelerated by reducing the torque and the power of the engine at a rate slower than the predetermined rate of the low-power mode while generating the brake torque by the motor.

Abstract: An internal combustion engine includes an ignition plug and an electronic control unit. The electronic control unit is configured to: (i) execute a lean-burn operation in a first operation region, (ii) execute an operation in a second operation region at an air-fuel ratio lower than an air-fuel ratio during the lean-burn operation, and (iii) control a gas flow in a cylinder so that a ratio of a change in a gas flow speed around the ignition plug during ignition to a change in an engine rotation speed in a first engine rotation speed region within the first operation region is smaller than the ratio in a second engine rotation speed region within the second operation region.

Abstract: An internal combustion engine comprises a fuel injector, a spark plug, an evaporated fuel purge device purging evaporated fuel in the fuel tank into an intake passage, and a control device. The control device can perform spark assist control for sequentially injecting premix-forming fuel and injecting ignition assist fuel from the fuel injector, while controlling the fuel injector and spark plug so as to make an air-fuel mixture formed by the injection of ignition assist fuel burn by the spark plug by flame propagation and to make the remaining fuel burn using the heat released by the flame propagation combustion by premixed compression self-ignition, and the control device makes the injection amount of premix-forming fuel decrease without changing the injection amount of ignition assist fuel when purging evaporated fuel into the intake passage by the evaporated fuel purge device compared to when not purging it.

Abstract: A battery control system includes a storage battery connected to a power network to be charged with and discharge power and a control device configured to control charging and discharging of the storage battery. The control device changes details of charging and discharging control of the storage battery when a deterioration state of the storage battery satisfies a predetermined condition at a point in time when a predetermined time has elapsed since start of use. The control device may gradually shift to control for suppressing deterioration of the storage battery as a use time of the storage battery becomes longer. In this way, it is possible to improve the economy of a consumer owning the storage battery.

Abstract: An air flow velocity calculating device of a internal combustion engine, has a cylinder, a spark plug, an air intake passage, an air flow controlling valve, an air flow velocity calculating portion, and an electric discharge current controlling portion. An electric discharge between a center electrode and a ground electrode is sustained during an electric discharge sustaining period. The electric discharge sustaining period is a period from when the electric discharge begins to when the electric discharge is intercepted by the air flow. Energy is supplied to the spark plug, so that the electric discharge current is sustained at a constant value by the electric discharge current controlling portion during an ignition period. The ignition period is a sum of an electric discharge sustaining period of a first electric discharge and electric discharge sustaining periods of second and subsequent electric discharges in one cycle of the internal combustion engine
