Cleaning and keeping clean an engine's vital components will restore and maintain power and economy.

Burning carbon-based fuel (diesel being a particularly dirty one) causes deposits that attach themselves to any part of the engine they come in contact with. This can include injectors, sensors and piston rings. 

BG Products, a company specialising in lubrication and deposit-cleaning, have found horsepower losses, through lost compression alone, of 8% in as little as 45,000 miles in some engines. 

These losses are caused by the build-up of carbon, from the combustion process filtering down onto the piston rings, plus deposits coming up from the oil side, getting behind the piston rings into the 'ringland' area of the piston. Together these deposits restrict the ability of the combustion gases to get behind the rings and expand them to create the seal required for compression.

Injectors have always been susceptible to deposits on the injector pintle. These deposits form quickly because of the position of the injectors – directly in the cylinder. The impact of these deposits is to interfere with the precise delivery and atomisation of the fuel molecules. This is critical as if the atomisation does not happen then oxygen cannot circulate amongst the fuel molecules and facilitate combustion.
