与普通增压相油柴机相比,旁通、补燃是超高增压柴油机最明显的标志和最重要的特征。旁通、补燃不仅是解决增压器和柴油机匹配,发动机启动;发动机高、低负荷下稳定运转以及发动机扫气的行之有效的技术手段,还是大幅度提高发动机升功率、开拓或扩大发动机使用领域的重要途径,更是改善发动机工作性能、使用性能、降低对环境污染的关键措施。旁通和补燃的控制或调节是关键环节。本文将着重探讨燃油调节方面的技术和原理方案。(对通旁控制虽涉及,但不作详细探论)。
Compared with the ordinary supercharged diesel engine, bypass, make-up is the most obvious symbol and the most important feature of super high pressure diesel engine. Bypass, make up the fuel is not only to solve turbocharger and diesel engine matching, engine start; engine high and low load stable operation and engine scavenging effective technical means, or substantially improve the engine power, to develop or expand the engine An important way to use the field, but also to improve the engine performance, use performance, reduce the key measures to environmental pollution. Bypass and afterburning control or regulation is the key link. This article will focus on fuel conditioning technology and principles of programs. (Control of bypass, though involved, but not discussed in detail).
