Abstract
An apparatus and method for testing and monitoring fuels produced for diesel engines. The cetane number of a supply fuel for a diesel engine is measured based on the value of the cetane number of two reference fuels. The autoignition delay is measured and compared to the delay for the reference fuels. The delay is measured using a diesel engine which operates at a constant speed with a constant volume compression ratio. The sample of the supply fuel may be drawn and tested in a research laboratory or may be used on line during the production of the fuel.
