Heavy-Duty Engine Testing Report-Correlation Testing of GMC (General Motors Corporation) 5.7L/MVMA Engine

摘要

The correlation between the heavy-duty test facilities of a manufacturer and the Environmental Protection Agency Motor Vehicle Emission Laboratory (MVEL) is of significant interest to both the manufacturer and EPA. It is especially important from a regulatory standpoint because of Selective Enforcement Audit (SEA) testing requirements. Thus, EPA/MVEL conducted testing on a Chevrolet heavy-duty gasoline fueled engine with the intent of providing correlation data for comparison with similar data developed by laboratories which conduct SEA emissions tests for the manufacturers of heavy-duty gasoline (HDG) engines. The round robin program was a joint effort on the part of EPA/MVEL and the Motor Vehicle Manufacturers Association (MVMA).
