Abstract:

The general goal of the project was to operate the Cooperative Fuel Research engine for rating diesel fuels cetane engine at conditions more representative of modern diesel engines and determine if results could be obtained that would better predict fuel behavior in modern engines. This goal was pursued by installing extensive instrumentation and data acquisition facilities on a cetane engine and evaluating the performance, emissions and combustion characteristics of ten different diesel fuels that had a wide range of different properties. After substantial experimental investigation, operating conditions for the cetane engine were established using an engine speed of 1200 rpm and a compression ratio of 201. The engine speed was sufficient to eliminate data reproducibility problems encountered at the standard cetane rating speed of 900 rpm. The 201 compression ratio was selected as a compromise between nominal values for DI and IDI engines. Detailed test, operation, and maintenance procedures were established to provide consistent results from the cetane engine.
