【日刊《日本机械学会志》1980年5月报道】三菱汽车工业公司研究成功喷射阀式小型汽油发动机。这种发动机的汽化器节气门上方的主吸气管与吸气阀之间介入一个来自另一个通路的第三个小型吸气阀,这个小型吸气阀与主吸气管吸气阀同时开、关。在导入空气或极稀薄混合气体后,混合气急速而稳定地燃烧,从而使排气不仅符合1978年规定的排气标准,而且燃料消耗量与不采取排气对策的情况相同。 Journal of Japan Society of Mechanical Engineers reported in May 1980 Mitsubishi Motors Corporation to study the successful injection valve small gasoline engine. A third small suction valve from the other passageway is interposed between the main suction pipe and the suction valve above the vaporizer throttle of this engine. This small suction valve is opened at the same time as the main suction valve, turn off. After the introduction of air or extremely lean mixture, the mixture burns rapidly and steadily, so that the exhaust gas not only meets the exhaust standard specified in 1978, but also has the same fuel consumption as the exhaust gas without exhaust gas.
