佩尔利尼T 20汽车发动机是美国通用汽车公司出产的V型六缸二冲程柴油发动机(GM6V—71N型)。在配气正时机构的调整上,除了和四冲程机一样地要校对气门间隙外,还要同时校正喷油器的正时高度。通过对这种发动机构造上的具体研究,很容易看出,通过摇转曲轴二次就可以准确地完成上述的校对工作。 Perlini T 20 car engine is produced by the United States General Motors V-six-cylinder two-stroke diesel engine (GM6V-71N type). In the timing adjustment of the valve timing mechanism, besides calibrating the valve clearance as the four-stroke machine, the timing height of the injector should be calibrated at the same time. Through the concrete study of the structure of this engine, it is easy to see that the above proofreading can be completed accurately by shaking the crankshaft twice.
