Abstract
With the new emphasis to reduce diesel exhaust emissions, there is a greater demand for better diesel fuels. Diesel fuel qualities can be improved either by better processing of crudes, which is expensive, or with the use of additives.
To develop additives which can prevent injector deposits or clean up already formed injector deposits, prechamber IDI engines are commonly used. Two direct injection (DI) engines tests have been developed in which effectiveness of additives to keep injectors clean can be evaluated. Another test has also been developed to determine clean up performance of an additive to remove already formed injector deposits in a DI engine can be assessed.
