http://cochise.uia.net/pkelley2/DynamicCR.html WebThe LBE concept refers to engine operation that is leaner (higher air to fuel mass ratio) than stoichiometric (chemically correct air-fuel ratio). The amount of work done during the expansion process in a lean-burn engine is relatively large (due to lower cycle temperature), resulting in a proportionally higher thermal efficiency.
