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 includes: a cylinder block including a bulkhead formed so as to separate adjacent cylinders; a crankshaft including a counterweight; and a gas-vent hole which is formed in the bulkhead within a radius of rotation of the counterweight when seen from below a piston bottom-dead-center position and an axial direction of the crankshaft, and which communicates between the adjacent cylinders. The counterweight includes at least one of a concave portion and a through-hole formed at at least a part of a region of the counterweight opposed to the gas-vent hole during rotation of the crankshaft. The concave portion hollows in a direction away from the gas-vent hole, the through-hole penetrating through the counterweight in a direction away from the gas-vent hole.

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 internal combustion engine includes: three or more cylinders including cylinders A, B and C according to the present disclosure arranged in a row in the cylinder row direction; and a balancer device for reducing engine vibration. The balancer device includes a balancer shaft arranged so as to extend from the cylinder A to the cylinder C along the cylinder row direction in a crank chamber. The balancer shaft includes: a first opening formed on the outer surface of the balancer shaft at a first location associated with the cylinder A in the cylinder row direction; a second opening formed on the outer surface at a second location associated with the cylinder C in the cylinder row direction; and a communication passage formed inside the balancer shaft so as to connect the first opening with the second opening.

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.
