Diesel Fuel
Cetane Boost
 Increases Cetane Number and Ignition Quality
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. AMSOIL Cetane Boost 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.
Smooths Operations
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 opertion, 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, AMSOIL Cetane Boost maintains the proper cylinder pressure rise rate. Maintaining the proper pressure rise rate improves driveability. AMSOIL Cetane Boost also improves driveability by reducing throttling pintle nozzle coking. Throttling pintle nozzle coking produces noise and emissions. AMSOIL Cetane Boost cleans up coke deposits and prevents the formation of new deposits. AMSOIL Cetane Boost also reduces varnish formation.
Improves Cold Engine Startability
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, AMSOIL Cetane Boost improves cold starting characteristics by reducing the time required to start the engine and the time required to establish smooth engine operation. AMSOIL Cetane Boost also allows engines to start at lower temperatures than they can with non-AMSOIL Cetane Boost treated fuels.
Reduces Emissions
AMSOIL Cetane Boost substantially reduces hydrocarbon and carbon monoxide emissions of heavy-duty on-road diesel trucks. By shortening the ignition delay, AMSOIL Cetane Boost helps fuel burn more completely, reducing carbon monoxide and hydrocarbon emissions. AMSOIL Cetane Boost may also reduce NOx and particulate emissions.
Available in Convenient Size
One 16-oz. can of AMSOIL Cetane Boost treats 100 to 200 gallons of diesel fuel and increases the fuel's cetane number three to seven points. Adding one can to 100 gallons of fuel provides maximum benefit.
Alcohol Free
AMSOIL Cetane Boost contains no ethanol, methanol, MTBE or other alcohol.
Compatible with AMSOIL Diesel Fuel Additive Concentrate
AMSOIL Diesel Concentrate improves fuel efficiency, lengthens component life and aids cold temperture fuel flow.
Increase Performance, Profits
AMSOIL Diesel Concentrate and AMSOIL Cetane Boost decrease expenses for fuel, injector cleanings and replacements - even costly road service for cold temperature related failures.
AMSOIL Cetane Boost increases fuel economy and injector life, promotes reliable cold temperature operations and reduces emissions and black smoke. AMSOIL Cetane Boost increases cetane number and ignition quality for smooth, powerful operation, reliable cold starting and decreased emissions and white smoke.
