摘要： PROBLEM TO BE SOLVED: To provide an intake device module having high muffling capability against noise generated from an engine with a simple structure. SOLUTION: An air cleaner 30 is installed above a head cover 10 mounted on a cylinder head. Fitting parts 20 are disposed on a top plate part 11 of the head cover 10, and slot parts 23 are formed on the fitting parts 20. Projecting parts 40 formed on a lower casa 32 of the air cleaner 30 can be fitted into the slot parts 23 of the fitting parts 20. Since the fitting parts 20 and the projecting parts 40 are formed surrounding a certain area, a closed space part 50 is formed by fitting the air cleaner 30 to the head cover 10. Since the space part 50 muffles the engine noise passing through the head cover 10 made of a resin, the muffling capability against the noise generated from the engine can be enhanced.

摘要： PROBLEM TO BE SOLVED: To install a variable inlet valve capable of enhancing the output performance of an engine without acting as a baffle when the valve is opened in a position equal from each port of a partition wall of a surge tank. SOLUTION: An internal combustion engine is constituted such that an inlet manifold introducing intake gas into each cylinder of a V-type multi-cylinder internal combustion engine is divided into two groups, each group of the inlet manifold is connected to one side surface in the length direction of each chamber of the surge tank 12 divided into two chambers 12A, 12B with the partition wall 13, and the intake gas is supplied to the surge tank 12 from the direction perpendicularly crossing to the side surface. An opening 14 is installed in the position equal from each port 16P in the central part of the partition wall 13, and a rotating shaft 18 to which a valve element 11 of the variable inlet valve 10 opening and closing the opening 14 is fit is positioned in the vicinity of the wall surface on the opposite side to the port. As a result, the valve element 11 does not act as the baffle when the valve element 11 is opened, pressure loss is decreased, and output performance is enhanced.

摘要： PROBLEM TO BE SOLVED: To provide a flange member of a simple structure for preventing slipping out of a bolt, and facilitating replacement of the bolt, and an intake manifold using that. SOLUTION: On a claw part 22 disposed on a flange main body 21 of the flange member 20, a protruded part 25 protruded to the inner circumferential side is formed. The protruded part 25 is protruded to the inner circumferential side over an outer circumference of a washer 32. In assembling the bolt 30 provided with the washer, the washer 32 is inclined to be easily inserted to the flange main body side of the protruded part 25. As the washer 32 is once inserted to the flange main body side, move of the washer 32 is limited by the protruded part 25. When the upside is turned down, therefore, the washer 32 and the bolt 30 provided with the washer will not be slipped out from the flange member 20. The bolt 30 provided with the washer can be easily removed by reverse procedures, thereby it can be easily replaced.

摘要： PROBLEM TO BE SOLVED: To provide an intake device module for reducing infiltration of foreign matter into the periphery of parts of an ignition system by integrally providing a head cover capable of housing the members of the ignition system and an air cleaner with each other. SOLUTION: A head cover 10 which is to be mounted to a cylinder head and a lower case 22 of the air cleaner are made of resin and are integrally formed with each other. A stick coil 40 as a part of the ignition system is fitted between an intake cover part 12 and an exhaust cover part 13 of the head cover 10. A cover member 24 for covering the stick coil 40 can be pulled out in the direction, expressed with arrow B from an opening part 27 of the lower case 22. A filter element is provided over the lower case 22, and the cover member 24 shields foreign mattes fallen off from the filter element to reduce fall of the foreign material onto the periphery of the stick coil 40. The stick coil 40 can be easily changed by pulling out the cover member 24.

摘要： PROBLEM TO BE SOLVED: To provide a small-sized muffler for reducing low-frequency noise generated in an intake pipe. SOLUTION: A recessed surface 14a of a parabola part 14 faces to the downstream side of the intake air flow, namely, to the noise generating side. A noise collecting valve 20 is a valve for intermitting the communication between an intake passage 10a and a noise collecting capacity chamber 17 in accordance with a change of noise pressure in the intake passage 10a. When noise pressure in the intake passage 10a is normal pressure, the noise collecting valve 20 releases a noise collecting hole 14b and a communication passage 15a, and therefore, the intake passage 10a communicates with the noise collecting capacity chamber 17. The normal pressure part of low-frequency noise is collected to the noise collecting capacity chamber 17 and then discharged from the exhaust pipe 18 to the outside of an intake system. High-frequency noise not collected by the noise collecting valve 20 is reflected from the parabola part 14, collected from a noise receiving port 31a positioned in a focal point to a noise receiving capacity chamber 32, and then damped in the noise collecting capacity chamber 32.
