由德国梅赛德斯—奔驰公司开发的新一代车用OM904LA柴油机已进入轻型商用车辆市场,并满足欧洲EUR02的排放限值。OM904LA发动机拥有高技术直喷式、增压、四缸、直列、带空—空中冷器的发动机的全新概念,其主要特征可用“多气门技术”,“单体泵高压喷射”和“发动机电子控制”等术语来概括。这样“小”的发动机具有几项直到今天还只有从8级发动机上才能得知的令人感兴趣的特点。 除了满足用户在寿命长、维护方便、可靠性和经济性方面不断增长的要求外,在该发动机设计中,不仅在满足全球的环境立法上,而且在提及满足预期中将更加苛刻的法规的充分潜力上倾注了很大的注意力。本文将OM904LA发动机的最重要设计特点及已达到的特性参数作详细说明和解释。
The new generation of automotive OM904LA diesel engines, developed by Mercedes-Benz AG of Germany, has entered the market of light commercial vehicles and meets the European EUR02 emission limits. The OM904LA engine features a new concept for high-tech direct injection, supercharged, four-cylinder, inline, air-to-air intercooler engines featuring “multi-valve technology”, “single pump high pressure injection” and “ Control ”and other terms to summarize. Such a “small” engine has several interesting features that can only be known from today’s level 8 engines. In addition to meeting the growing user demands for long life, ease of maintenance, reliability and economy, the design of this engine not only meets global environmental legislation but also refers to meeting the more anticipated regulations Full potential devoted a lot of attention. This article will OM904LA engine’s most important design features and parameters have been met to explain and explain in detail.
