Abstract: An internal combustion engine is provided. The internal combustion engine includes a supercharger that is arranged in an intake passage; an intercooler that is arranged downstream of the supercharger in a direction of intake air flow, in the intake passage; and a blow-by gas returning apparatus. The blow-by gas returning apparatus includes a bypass passage, an ejector, and a blow-by gas passage. The bypass passage connects a first position that is arranged between the supercharger and the intercooler, and a second position that is arranged downstream of the intercooler of the intake passage together. The ejector is arranged in the bypass passage, and configured to draw in blow-by gas from the crankcase through the blow-by gas passage when air flows through the bypass passage from the first position toward the second position.

Abstract: An internal combustion engine comprises a variable compression ratio mechanism that changes the relative position of a cylinder block with respect to a crankcase and a controlling device that controls the variable compression ratio mechanism. The variable compression ratio mechanism contains a driving device that rotates a shaft that includes an eccentric axis, and the drive device includes a clutch that blocks reverse input and is disposed in a drive power transmission route that transmits the rotational power of a motor to the shaft. The control device fixes the mechanical compression ratio to a predetermined low mechanical compression ratio when the amplitude of the rotational power vibration applied to an output shaft of the clutch is less than a predetermined determination value.

Abstract: An electric vehicle is configured to be switchable to an autonomous driving mode. The electric vehicle comprises an accelerator pedal, a shift device, a speaker, and a controller. The speaker outputs a pseudo engine sound. When the electric vehicle is not in the autonomous driving mode, the controller changes a motor torque and the pseudo engine sound in response to an operation state of the accelerator pedal and the shift device operated by a driver. When the electric vehicle is in the autonomous driving mode, the controller virtually determines the operation state of the accelerator pedal and the shift device and changes at least one of the motor torque and the pseudo engine sound in response to the virtual operation state.

Abstract: A crankshaft in which vibrations can be damped effectively without changing a design of a crankcase. The crankshaft comprises a first crank section located at one end of the crankshaft, and a second crank section located at the other end of the crankshaft. In the first crank section, a mass of a first inner balance weight is greater than a mass of a first outer balance weight. In the second crank section, a mass of a second inner balance weight is greater than a mass of a second outer balance weight.

Abstract: A battery electric vehicle is equipped with an MT that uses an electric motor as a driving power device and simulates an MT vehicle. Battery electric vehicle includes one or more processors configured to generate a pseudo-engine sound and to provide the pseudo-engine sound through one or more in-vehicle speakers. In MT mode, the one or more processors perform sound field control so that the listenability of the pseudo-engine sound in the first in-vehicle area and the second in-vehicle area different from the first in-vehicle area differs.

Abstract: In the present invention, an internal combustion engine is provided with a variable-compression-ratio mechanism with a variable mechanical compression ratio and the variable-compression-ratio mechanism comprises a drive device for changing the volume of a combustion chamber when a piston reaches top dead center. The drive device comprises a reverse input blocking clutch disposed in a drive power transmission path for transmitting the rotational force of a rotator. A control device estimates the reverse input torque applied to an output shaft of the reverse input blocking clutch and sets a gradient for torque output by the rotator and a continuation duration for continuing the torque increase on the basis of the reverse input torque.
