气门间隙的调整方法,每种车型的说明书上都有介绍,最好是按厂方的要求严格执行。但对一些新型汽车发动机可利用“双排不进”方法调整气门间隙。“双排不进”就是把气缸的工作顺序划分为四种情况:“双”表示该缸的两个气门都可以调整,“排”表示只调排气门,“进”表示只调进气门,“不”表示进、排气门都不可调。其具体调整步骤如下: (1)四缸发动机:例如丰四12R发动机气缸工作顺序为1、3、4、2,当1缸活塞处于压缩行程上止点时,其气门调整为:
Valve clearance adjustment method, each type of manual has been introduced, the best is the strict implementation of the requirements of the factory. But for some new car engines can be used “double row not enter” approach to adjust the valve clearance. “Double row does not enter” is the work sequence of the cylinder is divided into four cases: “Double” that the cylinder can be adjusted for both valves, “row” that only the exhaust valve, “into” that only into the gas Doors, “no” means that the intake and exhaust valves are not adjustable. The specific adjustment steps are as follows: (1) four-cylinder engine: for example, Feng four 12R engine cylinder work order of 1,3,4,2, when the cylinder piston in the compression stroke top dead center, the valve adjustment:
