The Analysis of Observed Burn Rates in a Spark-Ignition Engine and the Relation to Fuel Properties 2003-01-3125
The paper presents a statistical analysis of burn rates observed in a single cylinder spark-ignition engine. Parameters in a functional description of the burn rate were correlated to fuel blend composition and engine parameters. The analysis indicated that burn rate parameters were inter-linked and did not change in isolation. The use of sound statistical experimental design and analysis proved worthwhile in revealing tendencies that may otherwise have been misinterpreted. The features of the burn rate were discussed in lieu of the engine design, blend properties and test conditions.
