Abstract: A cylinder block of an internal combustion engine includes an oil drain hole that opens in a lower surface of the cylinder block. An oil pan is fixed to a lower part of the cylinder block and configured to collect oil. A balancer device is arranged inside the oil pan below a crankshaft. A baffle plate is flat and arranged inside the oil pan between the crankshaft and the balancer device covering the balancer device from above. An oil flow passage extends through the baffle plate in a thickness-wise direction. The oil flow passage is arranged in the baffle plate at a location overlapped with an oil falling path that extends from the oil drain hole to a bottom surface of the oil pan.

Abstract: A flywheel that has a flywheel main body and an inertia ring is provided. The flywheel main body has a disc-like shape. The inertia ring (i) has an annular shape, (ii) has a plurality of fastening portions, (iii) is fastened to the flywheel main body by the fastening portions, (iv) has a plurality of notches provided spaced apart in a circumferential direction of the inertia ring, in at least one of an inner peripheral surface or an outer peripheral surface of the inertia ring, and (v) has at least one of the fastening portions at each portion that is positioned between the notches.

Abstract: Hydraulic pressure control apparatus for controlling a pressure of a brake cylinder pressure, including a pump device connected to the brake cylinder and including at least one set of a pump for delivering a pressurized fluid to the brake cylinder and a pump operating electric motor, a low-pressure source for storing the fluid discharged from the brake cylinder, a solenoid-operated pressure control valve disposed between the low-pressure source and the brake cylinder and operated with an electric energy applied thereto, for controlling the brake cylinder pressure depending upon the electric energy, and a controller including a pressure increase control device for increasing the brake cylinder pressure by controlling the electric motor, and a pressure reduction control device or reducing the brake cylinder pressure by controlling the electric energy applied to the control valve.

Abstract: A hydraulic brake control apparatus includes a pressure supply inhibiting unit which inhibits supply of a brake fluid pressure to wheel cylinders by a first pressure supplying unit when a defect in a brake fluid path between a first flow control unit and the wheel cylinders has occurred, and inhibits supply of a brake fluid pressure to the wheel cylinders by a second pressure supplying unit when a defect in a brake fluid path between a second flow control unit and the wheel cylinders has occurred.

Abstract: A hydraulic brake control apparatus in which a master cylinder is connected to wheel cylinders via a master cylinder cut valve, and the wheel cylinders are connected to a reservoir tank via a switching valve, includes a check valve provided between the master cylinder and the wheel cylinders in parallel with the master cylinder cut valve, the check valve provided in a bypass passage of the master cylinder cut valve, the check valve allowing a flow of a brake fluid from the master cylinder to the wheel cylinders and inhibiting a flow of the brake fluid from the wheel cylinders to the master cylinder.
