一、我国内燃机测试仪器的现状与差距五十年代至六十年代初,我国内燃机测试技术水平相当低。专用的内燃机测试仪器几乎是空白。全国没有一家内燃机测试仪器的专业生产厂。从七十年代开始,进行了内燃机测试仪器的研制工作,陆续有一些产品进入国内市场,并有了专业生产厂。一九七六年机械工业部正式批准建立了湘西科学仪
First, the status quo and the gap between China’s internal combustion engine test instruments From the fifties to the early sixties, the level of internal combustion engine testing technology in China was quite low. The dedicated internal combustion engine test instrument is almost blank. There is no professional manufacturer of internal combustion engine test equipment in the country. Since the 1970s, the development of internal combustion engine test instruments has been carried out, and some products have entered the domestic market one after another, and there are professional production plants. In 1976, the Ministry of Machinery Industry formally approved the establishment of the Xiangxi Scientific Instrument.
