N2 - The goal of this work is to develop easily generalized models of heavy duty truck engine maps that allow for approximatecomparisons of engine performance, thus enabling fuel efficientmatching of engines to a set of corresponding loads and routes.This is achieved by applying dimensional analysis to create auniformly applicable, dimensionless Brake Specific Fuel Consumption (BSFC) map that fits the behavior of a wide range ofdiesel engines. A commonality between maps was found to occurwhen engine data is scaled by specific dimensional parametersthat target data consistency among the primary operating pointsacross engines. This common map highlights observable trendsin engine performance based on the influence of these same parameters being scaled across engines. The resulting dimensionless engine map fits the minimum BSFC regions of four dieselengines to within 2.5 percent.
