AMSOIL Diesel Fuel Additive Concentrate | AMSOIL Cetane Boost
AMSOIL Diesel Fuel Additive Concentrate (ADC) keeps fuel system passages and orifices open, allowing better fuel flow, fuel atomization and combustion for improved fuel economy and power. Laboratory and over-the-road testing shows the detergent in ADC provides fuel economy increases between 2.6 percent and 6.6 percent.
Standard tests show ADC provides outstanding cleanliness, corrosion inhibition, sludge inhibition and lubricity. By cleaning, conditioning and protecting injectors, pumps, filters, tanks and lines, ADC helps the entire fuel system last longer and work more efficiently.
The emissions-reducing agent in ADC has been shown to reduce emissions of hydrocarbon, oxides of nitrogen, carbon monoxide and particulate matter as much as 20 percent.
By reducing wax crystal size and precipitation, ADC lowers pour point as much as 35° F and cold filter plug point as much as 12° F, enhancing the reliability of cold starting and allowing engines to start at colder temperatures than they otherwise could.
ADC also contains a jet fuel de-icer which lowers the freeze point of ice crystals, inhibiting fuel line freeze-up and further enhancing the reliability of cold starting.
ADC significantly improves the storage stability of fuels, reducing operating problems and eliminating the need for frequent cleanings of tanks and equipment.
ADC contains no ethanol, methanol, or other alcohol which may damage seals, injectors, pumps or nozzles.
ADC is available in 16-oz. cans, 5-gallon pails, 30- gallon drums and 55-gallon drums. 16-oz. ADC treats 100 gallons of diesel fuel.
Cetane number is the measure of a diesel fuel’s ignition quality. Ignition quality is measured by ignition delay, the time between the start of fuel injection and the start of fuel combustion. Fuels with good ignition quality give short ignition delays and are assigned high cetane numbers.
Cetane, the colorless, oily hydrocarbon on which the cetane number scale is based, has extremely good ignition quality and is assigned a cetane number of 100. The cetane numbers of North American diesel fuels may be as low as 37, which may cause startability and driveability problems.
AMSOIL Cetane Boost, ACB, increases a fuel’s cetane number and improves its ignition quality. ACB encourages timely, uniform fuel ignition, discourages high pressure rate rise during the combustion cycle and solves startability and driveability problems associated with low cetane number diesel fuels.
Too long an ignition delay at high engine loads leads to an excessively rapid increase in pressure within the cylinder before combustion, which in turn, leads to diesel knock, or rough operation, especially on cold starts. Excessive pressure rise rates are theoretically caused by extra chemical reactions occurring before combustion. The products formed by the extra reactions burn rapidly. Rapid burning causes excessively rapid pressure rise in the cylinder. With a shorter ignition delay, the extra reactions don’t have a chance to occur, hence the rate of pressure rise is reduced. By reducing ignition delay, ACB maintains the proper cylinder pressure rise rate. Maintaining the proper pressure rise rate improves driveability. ACB also improves driveability by reducing throttling pintle nozzle coking. Throttling pintle nozzle coking produces noise and emissions. ACB cleans up coke deposits and prevents the formation of new deposits. ACB also reduces varnish formation.
In a cold engine with low intake air pressure, a long ignition delay causes difficult starting, misfiring and incomplete combustion. Incomplete combustion causes power loss and produces white smoke. White smoke is evidence of unburned or partially burned fuel. It occurs after starting a cold engine, during idling or other cold-engine operations.
By reducing ignition delay, ACB improves cold starting characteristics by reducing the time required to start the engine and the time required to establish smooth engine operation. ACB also allows engines to start at lower temperatures than they can with non-ACB treated fuels.
