地球温暖化成为大问题。近年来 ,世界各国越来越对 CO2 排放予以重视。其中 ,CO2 排放量少、燃料费用低廉的就是引人注目的内燃机。作为柴油机主要部件的气缸体 ,铸铁气缸体是其主流 ,但铸铁气缸体已成为燃料费用高和提高功率的障碍。因此 ,开发了溃散性型芯砂和高质量低速填充的压铸法 ,从而使密封型柴油机铝压铸气缸体质量减轻了 30 %。 Global warming has become a big problem. In recent years, all countries in the world pay more attention to CO2 emissions. Among them, less CO2 emissions, low fuel costs is a compelling internal combustion engine. As the main body of the cylinder block, cast iron cylinder body is the mainstream, but the cast iron cylinder block has become a high fuel costs and increase power obstacles. As a result, collapsible core sand and high-quality, low-speed die-casting methods have been developed, resulting in a 30% reduction in the quality of hermetically sealed aluminum die cast cylinders.
