Abstract

DC60 (29/07/52) Problems to be solved. To equip vehicle-operated engine units that are arranged to help fuel This will cause higher combustion efficiency and can be inhibited. This allows the variable fuel stream to flow into the auxiliary passageway, so that it has a non-shifting structure. Stacking and running at a lower cost and is highly responsive to accelerated oil squeezing operations. And to provide a straddle vehicle that includes vehicle engine units Solution The air inlet pipe 62, which is connected to the cylinder head 22, defines the water passage section. Primary Air Inlet B3 Throttle valves 69A, 69B Two valves are arranged in a 64-pipe fitting, spaced from each other in the direction of the intake air flow E1 through the auxiliary air inlet C1 connected to A section of the main air intake passage B3 between the two 69A, 69B throttle valves to direct air into the free space next to at least 47 nozzles during idling is established, the F1 core of the passageway. Air intake C1 crosses the plane G2, the G2 plane has line segments G1 spanning the opposite ends F2, F3 of the F1 axis in such a way that it has the least length selected Figure 12 for Provide vehicle-powered engine units that are arranged to help fuel This will cause higher combustion efficiency and can be inhibited.
