During normal diesel engine operations, fuel and combustion contaminants accumulate in the fuel system, combustion areas, and in exhaust after- treatment systems.

This causes rough idle, loss of power, decreased mileage, increased smoke, and slow throttle response. On newer diesels it may also trigger a OBD check engine light which signals the build of back pressure in the particulate reactor.

Unlike gasoline engines, diesel injectors are located in the hot environment of the combustion chambers. Injectors become clogged with fuel residues (carbon, varnish, and gums) due to the evaporation of fuel in the injector nozzle when the engine has been stopped.

Every time you stop a hot engine a small amount of residue adds to the already present build up. The more frequent the stops, the more rapidly the build up accumulates. This accumulation eventually reduces the flow of fuel through the injector and disrupts its spray pattern, causing the engine to run lean.

DIESEL FUEL TOOL An immediate and effective approach to diesel fuel system maintenance is the Engine Clean Diesel Fuel Tool. The Engine Clean Diesel Fuel Tool is a user- friendly machine that connects to the diesel fuel system. The Tool is filled with a highly concentrated detergent that is formulated to eliminate fuel, injector, and combustion related contaminants.

While the engine is idling, a mixture of the cleaning solution and diesel fuel is circulated through the entire fuel system. This includes the fuel pump, injectors, fuel rails, valves, rings and combustion chamber surfaces, and exhaust after treatment system.

The cleaning solution loosens carbon and other contaminants that are removed by the units 5-micron filter or expelled through the exhaust.

The Diesel Fuel Tool is a cost-effective way to restore engine efficiency and cut emissions, without removing or replacing costly fuel injectors and fuel pumps.
