Fuel injector deposits
Internal diesel injector components within HPCR engines are much smaller, lighter and more intricate than direct-injection diesel engines manufactured prior to 2007. With injection that occurs multiple times per combustion cycle at engine pressures up to 35,000 PSI, even the smallest deposit can cause issues within the tight tolerances of the injector (typically 1–3 microns). When using typical #2 diesel fuel, conventional deposits occur in the injector nozzle tip and internal diesel injector deposits (IDID) form deep inside the injector components.
Injector nozzles spray microscopic fuel droplets and become clogged by the smallest deposits. Even a stain or varnish clog can lead to decreased power and fuel efficiency. Minimizing all deposits is critical with high-pressure injection engine technologies. IDID can form suddenly deep inside the injectors and significantly reduce power and fuel economy, and in some cases, cause injector failure.
Fuel filter plugging
In addition to forming deposits in the fuel injection system, another known
issue that affects high-pressure injection (HPI) systems is premature fuel filter
plugging. Fuel filters capture unwanted contaminants from the fuel that left
unchecked, can cause serious damage. As the flow of the fuel through the fuel filter becomes restricted or plugged, a loss of power will result.
