Abstract: PROBLEM TO BE SOLVED: To provide a mounting member for securing fixing force of a screw, while securing a degree of freedom of a mounting position in attaching parts to a support member.
SOLUTION: A shaft diameter (root diameter) of a shaft part 14 of a self-tapping screw 10 is d1 and its outer diameter is d2. The support member 20 is made from resin material, and the self-tapping screw 10 is screwed into a long-hole shaped lower hole 22 with width b of the support member 20. The width b of the lower hole 22 is narrower than the shaft diameter d1 of the self-tapping screw 10. As the self-tapping screw 10 is screwed into the lower hole 22, elastic recovery force is generated in the support member 22 so that the support member 20 pushes the self-tapping screw 10 from both sides. Further, the support member 20 is plastic-deformed around the self-tapping screw 10 so that a part of the support member 20 wraps around the self-tapping screw in a circumference direction.

Abstract: PURPOSE:To highly precisely detect a misfire with a simple structure by mounting a vibration detecting means on an internal combustion engine, and detecting the misfire on the basis of the detected vibration. CONSTITUTION:During the operation of an internal combustion engine m1, a vibration detecting means M2 detects the vibration of the engine M1, and an ignition timing detecting means M3 detects the ignition timing based on the rotation of the engine M1. A combusting state signal arithmetic means M4 processes the vibration signal detected by the means M2 synchronously with the ignition timing detected by the ignition timing means M3 and operates the combusting state signal instructing the combusting state of the engine M1. A misfire judging means M5 judges the misfire when the signal computed by the combusting means M4 does not satisfy a standard value. Thus, the misfire can be highly precisely detected with a simple structure.

Abstract: PROBLEM TO BE SOLVED: To solve a problem that suitable detection of an intake pipe pressure becomes impossible when a portion of a throttle body downstream of a throttle valve is broken by impact caused due to collision of a vehicle or the like in the throttle body of an internal combustion engine for detecting an intake pipe pressure and for setting a fuel injection quantity.
SOLUTION: The internal combustion engine is mounted on the vehicle and comprises an internal combustion engine body having an intake system, a pressure sensor disposed in the intake system and outputting a signal for setting a fuel injection quantity and the throttle body having the throttle valve built therein for controlling an intake air amount and disposed upstream of the pressure sensor. The throttle body is formed of an inlet side pipe body portion through which intake air enters, a valve pipe body portion having the throttle valve built therein in communication with the inlet side pipe body portion and an outlet side pipe body portion through which the intake air passing the valve pipe body portion exits toward the pressure sensor. Strength of the inlet side pipe body portion is set lower than strength of the outlet side pipe body portion.

Abstract: PROBLEM TO BE SOLVED: To share a reserve tank, and to suppress flow of cooling water of an internal combustion engine side into an electric motor cooling system even if the reserve tank is shared. SOLUTION: This power cooling device for a hybrid vehicle has a circulating passage 10 for a first cooling water which cools an internal combustion engine 1, a circulating passage 20 for a second cooling water which cools an electric motor 2, and a single reserve tank 30 which communities the circulating passage 10 for the first cooling water with the circulating passage 20 for the second cooling water. Passage area A of an entrance's throttle 15 of the first cooling water circulating passage 10 to the reserve tank 30, passage area B of an exit's throttle 16, passage area C of an entrance's throttle 25 of the second cooling water circulating passage 20 to the reserve tank 30, and passage area D of an exit's throttle 26 are related by the equation B/A>=D/C.
