采用电子控制喷射系统的中速柴油机通过喷射特性的适应性和柴油机优化运行赢得用户好评。这类喷射系统已经广泛应用于高速柴油机上,在中速柴油机上的应用则处于起步阶段。Caterpillar公司已经开发并正在研究应用于C280、M32C、M43C、M25C和M20C等中速机平台的系统。本文将论述在改进排放性能(减少NOx、颗粒物、CO2以及降低噪声)方面存在的潜力,明确指出电控柴油机关键部件所必备的特性,并介绍为使其具备这些特性所采用的两种不同的方案。
Medium-speed diesel engines with electronically controlled injection systems have won acclaim from users through the adaptability of injection characteristics and the optimized operation of diesel engines. This type of injection system has been widely used in high-speed diesel engine, the application of medium-speed diesel engine is in its infancy. Caterpillar has developed and is working on systems for medium-speed platforms such as C280, M32C, M43C, M25C and M20C. This article discusses the potential for improving emission performance (reducing NOx, particulate matter, CO2, and noise), clearly identifying the features essential for the key components of electronically controlled diesel engines and describing the two different approaches taken to make them available Program.
