The article discusses examples of several design solutions for compression-ignition engine fuel systems. The solutions presented in chronological order indicate trends and directions in the development of fuel systems. The article also presents the basic features of successive solutions and their operating principles.A characteristic feature of a compression-ignition engine, distinguishing it from other types of engines, is that this engine draws in clean air and then compresses it to such a high pressure that the temperature as a result of this process rises above the auto-ignition temperature of the fuel, which is injected into the cylinder at the end of the compression stroke.
This engine is also called a high-pressure engine or, after the name of its creator, a Diesel engine.
Modern compression-ignition engines, regardless of their application, differ significantly from their prototype built in the years 1893-1897 at the MAN factory.
However, its basic feature, consisting of the auto-ignition of fuel without the use of auxiliary ignition devices, has not changed. The most significant changes concern fuel systems, which is caused by constantly tightening regulations regarding exhaust emissions, noise, and economic considerations. (…)
