此次下线的是第五代EA888 2.0T，配备与保时捷同源的VTG可变截面涡轮增压技术、500bar超高压燃油直喷系统以及全工况米勒循环三大核心技术。 通过动态调节涡轮叶片角度，发动机可在1500转时即输出400N·m峰值扭矩，并将高扭矩平台延展至4500转，消除了传统涡轮的"迟滞效应"。配合全工况 米勒循环技术，通过可变气门升程（AVS）和双VVT系统，实现膨胀比大于压缩比的高效燃烧模式，WLTC综合油耗降至8.35L/100km，热效率较第三代 机型提升40%，高速工况动力输出稳定性显著增强。 1月20日，一汽-大众第1000万台EA888发动机在大连基地下线。EA888系列发动机于2006年全球首发，历经五代迭代，全球累计装机量已超过2000万 台。 大众一汽发动机生产的EA888主要适配旗下大众、奥迪两大品牌的主力车型，包括迈腾、帕萨特、探岳、途观L、A4L、A6L、Q5L、Q3等，是国内 市场德系中型车和SUV的核心动力源。 ...

Core Insights - The 10 millionth EA888 engine from FAW-Volkswagen was produced at the Dalian base on January 20, marking a significant milestone for the engine series which has seen over 20 million units installed globally since its debut in 2006 [1][3] Group 1: Engine Technology - The latest fifth-generation EA888 2.0T engine features advanced technologies including VTG variable geometry turbocharging, a 500bar high-pressure direct fuel injection system, and a full-load Miller cycle, enhancing performance and efficiency [3] - The engine achieves a peak torque of 400N·m at 1500 RPM, with a torque plateau extending to 4500 RPM, effectively eliminating traditional turbo lag [3] - The WLTC combined fuel consumption is reduced to 8.35L/100km, with thermal efficiency improved by 40% compared to the third-generation model, and enhanced stability in high-speed power output [3] Group 2: Market Position - The EA888 engine is primarily used in key models from Volkswagen and Audi, including Magotan, Passat, Tayron, Tiguan L, A4L, A6L, Q5L, and Q3, serving as the core power source for German mid-size cars and SUVs in the domestic market [5]
