Abstract: PROBLEM TO BE SOLVED: To improve cooling performance while narrowing an interval between cylinder bores.
SOLUTION: Since one end of a heat pipe 50 whose other end is arranged at a low temperature position outside the cylinder bores 10, 20 is arranged at a halfway position to a wall part 11 between mutually adjacent cylinder bores 10 and 20, the interval of the cylinder bores 10, 20 can be narrowed when compared with a case where the heat pipe is provided by crossing the wall part between the cylinder bores. When heat medium having gas phase or liquid phase in the heat pipe 50 performs convection, its direction is simple so that cooling performance is improved.

Abstract: PROBLEM TO BE SOLVED: To reduce the size of a motor while securing sufficient torque to rotate a control shaft.
SOLUTION: The motor 14 is connected to the control shaft 12 of a variable valve train 10 via a speed reduction mechanism 18. The motor 14 controls lift amount of a valve in accordance with the rotating angle of the control shaft 12. A ratio (R1/R2) between gear diameters R1, R2 of a worm gear 20 and a worm wheel 22 in an engagement position P is formed to become smaller as the control shaft 12 is rotated to a lift increasing direction B. Thus, for example, even in the state where output torque of the motor 14 is constant, in a large operation region from small lift amount to large lift amount, the appropriate magnitude of rotating torque corresponding to valve reaction force can be applied to the control shaft 12. Therefore, since this eliminates the necessity of determining the specifications of the motor 14 in accordance with requirements on the large lift amount side, the motor with small output can be adopted.

Abstract: PROBLEM TO BE SOLVED: To restrain inconvenience in ordinary operation of an internal combustion engine, by early raising the temperature of fluid desired for early raising the temperature in warming-up operation of the internal combustion engine. SOLUTION: An exhaust passage 10 is arranged in a cylinder head 1, and a collecting part 15 is formed in the exhaust passage 10, and a water jacket 20 being an early heating fluid flowing means is also arranged. Out of these members, the collecting part 15 can take out cooling water of an elevated temperature state by taking out the cooling water just after being flowed outside the collecting part 15 in the warming-up operation since exhaust gas gathers and the temperature easily becomes high. In the warming-up operation, the inconvenience such as hardly cooling a combustion chamber 8 in the ordinary operation can be restrained by taking out the cooling water just after being flowed outside the collecting part 15. As a result, the temperature of the cooling water being the fluid desired for early raising the temperature in the warming-up operation of the internal combustion engine is quickly elevated and the inconvenience in the ordinary operation of the internal combustion engine can be restrained.

Abstract: PROBLEM TO BE SOLVED: To provide an oil level detection device capable of appropriately detecting an oil level with a simple structure.
SOLUTION: This oil level detection device is applied to an internal combustion engine 1 fastening a cylinder head 4, a cylinder block 2, a crank case 5 and a lower case 6 by a through bolt 7 as one body. A through hole 7a passing through the through bolt 7 in an axial direction is included and the through hole 7a is used as a guide for an oil level gage 11. The oil level gage 11 can be appropriately guided to oil stored in an oil pan 10 without increasing the number of parts. Also if the through bolt 11 is a through bolt of a crank cap part 6b of the lower case 6, interference with a rotating object such as a crank shaft can be prevented. Since an insertion hole 9a is positioned on an axis of the through hole 7a, detection of oil level can be done appropriately in a short period of time.
