1.配气相位的检查与调整凸轮轴配气凸轮的相对位置与大小在制造时已予保证,实际中只需检查调整一缸进气门的配气相位。检查方法在气缸盖上置一带支架的百分表,表头顶在一缸进气门弹簧座平面上(近风扇处为一缸)。顺时针摇转曲轴,当指针摆动的一刹那,立即停摇。此时若飞轮上“1/4”刻线距离机体刻线右侧(从飞轮端看)2.5～3个齿,表明1缸进气门开启时间为排气上止点8°,配气相位正确。若指针摆动,而“1/4”刻
1. Gas phase inspection and adjustment Camshaft gas distribution cam relative position and size of the manufacturing has been guaranteed, in fact only need to check the adjustment of a cylinder inlet valve gas phase. Inspection method Set on the cylinder head with a bracket dial indicator, the top of the table in a cylinder intake valve spring seat plane (near the fan at a cylinder). Crank the crankshaft clockwise, when the pointer swinging moment, immediately stopped shaking. At this point if the flywheel on the “1/4” engraved line from the body engraved on the right side (from the flywheel end) 2.5 to 3 teeth, indicating that 1 cylinder intake valve opening time for exhaust top dead center 8 °, with Gas phase is correct. If the pointer swing, and “1/4 ” engraved
