Investigations of injector deposits in modern diesel engines

Abstract

Traces of some metallic elements that may contaminate diesel fuel are a very significant factor initiating and accelerating the formation of deposits in diesel injection systems. Such deposits disturb proper operation of modern high-pressure injection systems, which has an adverse effect on the engine performance and operating parameters. The paper discusses the results of engine tests related to the influence of traces of zinc on the deterioration of the operating parameters of injection systems manifesting itself in decreased engine power.
