The most complex part of the diesel engine is the injector. The injector has to be able to handle the heat and pressure within a cylinder while still being able to distribute the fuel in a fine mist. Symtoms you may notice when the injectors need cleaned include poor fuel economy, power loss, rough idle, increased smoke and slowed throttle response. The BG Diesel Injection Service will remove deposits from the fuel injectors, clean soot-black deposits from the fuel filter, prevent component corrosion and cleans stuborm oil deposits.
