摘要： An outboard engine is disclosed that includes an idling chamber that communicates with a guiding outlet of a first exhaust path and that is open to the atmosphere. The idling chamber includes a cooling water communicating path that communicates with a cooling water supplying path, and a pressure adjusting valve that opens the cooling water communicating path when the value of the water pressure in the cooling water supplying path reaches a threshold value. When the value of the water pressure in the cooling water supplying path reaches the threshold value, the pressure adjusting valve opens and a portion of cooling water is guided to the idling chamber through the cooling water communicating path.

摘要： An outboard motor S has an exhaust manifold passage 37 for carrying exhaust gas from combustion chambers 30. The exhaust manifold passage 37 is formed in a part of a cylinder head 22 in an exhaust-side part of an internal combustion engine E on the side of the cylinder head 22 with respect to a joint surface P of a cylinder block 20 joined to the cylinder head 22. An exhaust passage 38 is formed in the cylinder block 20 and connected to the exhaust gas outlet 37e of the exhaust manifold passage 37 in the joint surface P. An electrical equipment box 50 holding electrical equipment is placed in the exhaust-side part so as to overlap the exhaust passage 38 when viewed in vertical direction. An electrical equipment box 50 is disposed adjacent to the cylinder head 22 with respect to the direction parallel to the axes of cylinders 20a. It is thus possible to increase freedom of arranging parts at positions farther from the cylinder head than the electrical equipment box and freedom of determining the sizes of those parts.

摘要： A water-cooled internal combustion engine has a cylinder head 21 provided with a cylinder head water jacket Jh through which cooling water flows. The cylinder head water jacket Jh includes a combustion chamber water jacket 70 surrounding combustion chambers 26 and an exhaust passage water jacket 71 around an exhaust manifold passage 38. The exhaust gas discharged from the combustion chambers 26 through exhaust ports 28 flows through the exhaust manifold passage. The exhaust passage water jacket 71 is divided into an upstream water jacket 72a and a downstream water jacket 72b by a partition wall 75. The cooling water flows from both the upstream water jacket 72a and the downstream water jacket 72a into the combustion chamber water jacket 70. Equality in temperature between a combustion chamber wall and an exhaust passage wall is improved and the cylinder head 21 is heated in a uniform temperature distribution.

摘要： A multicylinder internal combustion engine has a valve chamber containing a valve train for opening and closing intake valves and exhaust valves, and decompression mechanisms. First, second and third cylinders are arranged in a row parallel to an axial direction parallel to the axis of a camshaft. An exhaust cam for opening and closing the exhaust valve, which is opened and closed by the decompression mechanism, for the second cylinder is not coincident with respect to the axial direction with an abutment end of the exhaust valve with which a rocker arm driven by the exhaust cam comes into contact, and is coincident with respect to the axial direction with the decompression mechanism. Thus, a space for placing the decompression mechanism is secured while suppressing increase in the length of the camshaft and in the longitudinal size of the valve chamber. Consequently, the internal combustion engine can be formed in compact construction. Interference between the pump cam and the decompression mechanism can be avoided and increase in the length of the camshaft can be suppressed by disposing the centrifugal weight of the decompression mechanism for the third cylinder at a specific position on the side of the cam lobe of the pump cam as viewed in the axial direction.

摘要： An air intake muffler has an enclosure having a longitudinal axis, a first portion, and a second portion defining with the first portion an interior space of the enclosure. An air intake connecting duct is formed unitarily with the first portion of the enclosure and extends outwardly from the interior space of the enclosure. A pair of outside air intake ducts for introducting outside air into the interior space of the enclosure diverge in a V-shaped configuration from the longitudinal axis of the enclosure. Each of the outside air intake ducts has a pair of mating concave portions each formed unitarily with a respective one of the first and second portions of the enclosure and extending outwardly from the interior space of the enclosure.
