摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve mounting structure of an engine capable of regulating the rotation of a fuel injection valve while suppressing a cost increase. SOLUTION: The structure comprises the fuel injection valve 4 and a rotation-regulating member. The fuel injection valve 4 is mounted to a fuel injection valve-mounting hole, and a flat rotation regulating part 8b is formed at a part of the approximately cylindrical circumference of the valve. One end side of the rotation-regulating member is fixed to an engine body and the other end side is engaged with the rotation regulating part 8b for regulating rotation in the axial direction of the fuel injection valve 4. The fuel injection valve 4 is provided with a resin-made housing member 8 where a coupler connecting part 8a for coupler connecting is formed for feeding power to an electromagnetic solenoid in the fuel injection valve, and the housing member 8 and the rotation-regulating part 8b are integrally formed. Accordingly, forming the rotation-regulating part 8b at the resin-made housing member 8 where the coupler connecting part 8a is formed makes machine work for forming the rotation-regulating part unnecessary to regulate the rotation of the fuel injection valve 4 while suppressing the cost increase.

摘要： PROBLEM TO BE SOLVED: To suppress an amount of outward protrusion of the side of a cylinder head when fixing a pressing member to press the fuel injection valve of a direct injection type engine onto the cylinder head to the cylinder head. SOLUTION: A fuel injection valve 60 is fixed to a cylinder head 12 in a pressed state by making the engagement part 91 of a pressing member 90 engaged with the fuel injection valve 60 and fixing a fixed part 93 to the cylinder head 12 by a bolt 92. The engagement part 91 of the pressing member 90 and the fixed part 93 are disposed in a row along the side part of the cylinder head 12. Since the bolt 92 penetrating through the fixed part 93 and breaking into the cylinder head 12 is not positioned toward the side of the cylinder head 12, an amount of protrusion of the side of the cylinder head 12 can be suppressed.

摘要： PURPOSE:To check backflow of exhaust gas as well as to prevent combustibility from lowering by installing a replacing air passage in a separate side housing at each cylinder, and also installing a secondary air passage in a side housing at the opposite side to the replacing air passage at each cylinder. CONSTITUTION:Each of replacing air passages 26-28, feeding air for exhaust gas replacement is installed in an operating chamber for an exhaust stroke. Each of secondary air passages 30-32, feeding secondary air for exhaust emission control, is installed in an intake port. These replacing air passages 26-28 are installed in separate side housings 3, 5, 7 and 9 at each cylinder. Likewise, these secondary air passages 30-32 are installed in these side housings 3, 5, 7 and 9 at the opposite side to these replacing air passages 26-28 at each cylinder. The replacing air and secondary sir are fed to each cylinder from each side housing. Thus, backflow of exhaust gas is checked and, what is more, any drop in combustibility is preventable.

摘要： PURPOSE:To make a drop in working gas temperature due to a drop in a compression ratio compensable in a proper manner, by installing a heating device additionally in and around an interconnecting passage which interconnects an operating chamber existing in a compression stroke of a trochoidal space to another operating chamber existing in the suction stroke. CONSTITUTION:In a pair of trochoidal spaces 15 and 16 at both sides of an intermediate housing 6, an interconnected passage 20, interconnecting an opera tion chamber existing in a compression stroke on one side to another operating chamber existing in a suction stroke on the other, is formed there, in which a control valve 21, controlling an air-flow quantity according to engine load, is installed. And, an exhaust gas passage 25 having an exhaust gas recirculating (EGR) valve 22 is set up in and around the interconnecting passage 20. There fore, at a pumping loss decrement range where a part of working gas is made to flow out, this working gas flowing inside the interconnecting passage 20 is heated, whereby a dropping portion of working gas temperature due to a drop in a compression ratio is properly compensated, thus combustibility is improved.
