This internal combustion engine includes an oil seal attached to a crankshaft of an internal combustion engine main body, and a cover member including an oil seal securing portion for securing the oil seal attached to the crankshaft, the cover member including a first main body attachment portion which is arranged in a vicinity of the oil seal securing portion and which is for attaching the cover member to the internal combustion engine main body by a first fastening member.

Internal combustion engine and cover member attachment structure for internal combustion engine

An internal combustion engine includes a cylinder block, an auxiliary machinery attachment member arranged at a side wall of the cylinder block, the auxiliary machinery attachment member to which an auxiliary machine is attached, and a separator portion disposed in a void between the cylinder block and the auxiliary machinery attachment member, the separator portion being provided as a separate member from the cylinder block and the auxiliary machinery attachment member to perform gas-liquid separation on blow-by gas.

Internal combustion engine and separator structure thereof

An internal combustion engine includes: a chain cover that is attached to an internal combustion engine main body having a crankshaft; an oil seal that is mounted on the crankshaft in the vicinity of the chain cover; a metallic oil seal fixing member that is disposed on a surface of the chain cover and fixes the oil seal, the surface being present opposite to the internal combustion engine main body; and a first sealing member that is disposed between the oil sealing fixing member and the chain cover.

Internal combustion engine and structure of chain cover of the same

An oil pump apparatus includes a body, a first rotor and a second rotor disposed in the body so as to be able to rotate and a regulator valve mechanism for regulating the pressure of oil discharged to portions of an engine, wherein the regulator valve mechanism is disposed in the inside of the body and the engine and includes a regulator valve member which moves in the direction being in parallel with a rotation as of the first and second rotors in response to the discharged oil pressure.

Oil pump apparatus

A throttle control apparatus that maintains a vehicle's ability to run during a throttle system failure includes a throttle-controlling ECU that calculates a throttle opening instruction value from an accelerator stroke signal outputted from an accelerator pedal sensor, and supplies a motor with a current value based on the instruction value, to control the opening of a throttle valve. If the deviation between the instruction value and the output value from a throttle sensor is greater than a reference value, the ECU determines that there is a system failure. If it is determined that a system failure exists, an internal combustion engine controlling ECU varies the number of cylinders of the engine in operation to vary the engine output, depending on whether the amount of depression of the accelerator pedal by the driver is greater than a predetermined value.
