汽油发动机废气中的有害物质含量标准,苏联已于1970年试行。当时批准颁布了FOCT16533—70《汽油车废气中一氧化碳最大含量标准以及试验方法》。1978年批准了FOCT17.22.03—77《环境保护、大气、汽油车废气中一氧化碳含量、标准和确定方法》,并用后者代替了1970年颁布的标准。这个标准规定汽油发动机在空转规范下,废气中一氧化碳含量的确定方法(当曲轴低速运转时或等于0.6倍的额定转速)。 Gasoline engine exhaust emissions of harmful substances in the standard, the Soviet Union in 1970 trial. At that time, it approved the promulgation of FOCT16533-70 “the maximum content of carbon monoxide in gasoline off-gas standards and test methods.” In 1978, FOCT17.22.03-77, “Environmental Protection, Atmospheric, Gasoline, and Determination of Carbon Monoxide in Gasoline Scraps,” was approved and replaced by the 1970 standard. This standard specifies the method for determining the amount of carbon monoxide in exhaust gas under the idling regulation of a gasoline engine (when the crankshaft is operating at a low speed or equal to 0.6 times the rated speed).
