Q:宝马M4安全车的缸内喷水技术是什么?喷的液体是单纯的水吗?A:您好,首先来讲讲缸内喷水技术(Water Injection)(为了方便我暂且把喷入的混合物流体称为“水”)。在内燃机中喷水,也被称为反爆声注射,喷射水进入气缸或输入燃料空气混合物冷却发动机的燃烧室,达到更大的压缩比,在很大程度上消除发动机爆震的问题。 Q: BMW M4 safety car in-cylinder water spray technology is what? Spray the liquid is pure water? A: Hello, first of all to talk about in-cylinder water injection technology (Water Injection) (for the convenience of me to spray The fluid mixture is called “water”). Spraying water in an internal combustion engine, also known as anti-popcorn injection, injects water into the cylinder or mixes the fuel-air mixture to cool the combustion chamber of the engine, achieving a greater compression ratio that largely eliminates engine knock problems.
