节能减排是现代车用发动机发展的永恒主题和不懈追求的目标。近12年来,Volkswagen公司在1.4 L汽油机平台的基础上,运用汽油缸内分层直接喷射和增压等新技术,开发出1.4 L燃油分层直接喷射自然吸气机型和1.4 L涡轮-机械式复合增压分层喷射(TSI)机型,不同的功率等级满足了众多车型的需求,并实现了优异的燃油耗和卓越的行驶动力性,满足了日趋收紧的排放标准限值要求,树立了车用汽油机发展的新里程碑。2012年,又应用统一的标准部件实现模块化结构型式,开发了新一代1.4 L TSI汽油机,大大降低了量产和用户维修保养的成本。继而,首次在小型直列4缸机上运用气缸切断技术,以进一步挖掘节油潜力。介绍了Volkswagen公司1.4 L汽油机全系列型谱各机型的结构和性能,旨在使读者能从世界著名跨国公司开发系列机型的演变过程中,借鉴现代新技术、新工艺和新材料,拓展思路,充分利用开发新系列产品的成功经验。这是一种事半功倍的有效方法。
Energy-saving emission reduction is the eternal theme of the development of modern car engines and the relentless pursuit of the goal. In the past 12 years, based on the 1.4 L gasoline engine platform, Volkswagen has developed 1.4 L fuel stratified direct injection natural aspirator and 1.4 L turbo-machinery based on new technologies such as stratified direct injection and pressurization in gasoline cylinders Type compound supercharged stratified squirting (TSI) models, different power levels to meet the needs of many models, and achieved excellent fuel consumption and excellent driving dynamics to meet the increasingly stringent emission standards limit requirements, Set a new milestone in the development of automotive gasoline engines. In 2012, a unified standard component was adopted to realize the modular structure type. A new generation 1.4 L TSI gasoline engine was developed, greatly reducing the cost of mass production and user maintenance. Then, for the first time, the cylinder cut-off technology was applied to the small in-line 4-cylinder engine to further tap the potential of fuel economy. This paper introduces the structure and performance of Volkswagen 1.4L gasoline engine with a full range of type spectrum, aims to enable readers to learn from the modern new technologies, new processes and new materials, from the evolution of a series of world famous multinational companies to develop Ideas, make full use of the successful development of new products experience. This is an effective way to do more with less.
