化油器的怠速理论与调节步骤(国外英文资料) The idle theory and the adjustment procedure of the carburetor In this paper, from the post of powerful and unconstrained style, both in depth and breadth can be included in the textbooks, to ride a motorcycle, motorcycle, motorcycle users bring the Gospel. Idle speed means the engines slow and idle speed, which is usually between 1200r ~ 1800r/min for the GY6 engine used in the scooter. Some GY6 engines vibrate between 1300 and 1400r/min, and it is better not to adjust the idle speed at this time. Four blunt gasoline engine to maintain regular idle rely on fuel, air, internal resistance, the rotating speed of ignition Angle ~ ~ ~ ~ effect, manually adjust the four, plus the effect of speed effect, determines the engine idle speed and steady state, as well as the engine startup performance. Fuel: Decided to idle is idle carburetor oil fuel supply steam screw, on vacuum membrane carburetor, idle oil steam adjusting screw in the left side of the carburetor, is a hidden copper screws, head to the left horizontally, slender usually use the word, and from the left of the carburetor, screw the implementation regulation. This screw turns clockwise = close off the idle oil, and turn counterclockwise = open the idle oil road. When adjusting the idle speed, usually will have this oil vapor screw = closed idle oil, and then to counterclockwise screw out 1 ~ 2 ring = a little oil, open the idle speed is a bit like a tap. On cross bike plunger type carburetor, idle speed adjustment screw oil vapor concentration in the left side of the carburetor, usually oblique above ones head to the left of the copper screw. Usually using a long, thin word, you can use the left side of the carburetor to adjust the concentration of the idle oil. (some plunger screws are also on the left, usually horizontally, and be careful!) This idle speed dating gas screw clockwise to twist the end = = idle oil steam gas shut off idle speed dating, the largest open to counterclockwise t
