植根中国 共创辉煌
康明斯与中国的历史渊源可以追溯到半个多世纪前的1940年代。1941年3月11日，美国总统弗兰克林•罗斯福签署《租借法案》，向包括中国在内的38个国家提供战时援助。《租借法案》对华军援物资中就包括配备康明斯发动机的江防巡逻艇和军用卡车。
1944年末，一家重庆企业致函康明斯公司，寻求建立商业联系，在中国进行康明斯发动机的本地化生产，时任康明斯发动机公司总经理埃尔文•米勒在回函中对此表示了浓厚的兴趣，希望中日战争结束后康明斯能够在华建厂。由于众所周知的原因，米勒先生的想法只能等到三十年后的1970年代，伴随着中美关系的逐步缓和，才有望变为现实。
康明斯及其关联子公司在华累计投资超过10亿美元，作为中国柴油机行业***的外商投资者，康明斯与中国的商业联系始于1975年，时任康明斯董事长埃尔文•米勒先生首次访问北京，成为***来华寻求商业合作的美国企业家之一。1979年中美建交，中国对外开放伊始，***康明斯驻华办事处就在北京成立。
康明斯是***在华进行发动机本地化生产的西方柴油机公司之一，1981年重庆发动机厂开始许可证生产康明斯发动机，1995年康明斯***家中国合资发动机工厂成立,1997年，康明斯在华正式设立区域总部，康明斯（中国）投资有限公司在北京成立，统筹管理康明斯在东亚的投资与业务发展。到目前为止，康明斯在华总计设有29家机构，包括15家合资企业，员工9,000多名，生产发动机、发电机组、交流发电机、滤清系统、涡轮增压系统、后处理和燃油系统等产品，康明斯在华服务网络包括12家区域服务中心、30多家客户支持平台和2000多家在华独资及合资企业授权经销商。康明斯长期坚持与中国大型企业结成战略联盟，实现共同发展。作为***来华进行本地化生产的外资柴油机企业，三十多年来康明斯已经与包括东风汽车、陕汽集团和北汽福田在内的中国商用车领先企业组建了四家发动机合资厂，康明斯二十四个发动机系列中已有十五个在中国本地生产。
康明斯是***家在华设立研发中心的外资柴油机公司，2006年8月康明斯与东风公司合作设立的发动机技术研发中心在湖北武汉正式启用。
2013年康明斯在华销售额达35亿美元，中国区已经成为康明斯全球规模***、增长最快的海外市场。
历经三十多年的发展，康明斯已经成为中国发动机产业的有机组成部分，通过合资/独资生产和技术转让，为中国发动机产业的现代化作出了自己的贡献。
