The development of testing techniques for the accurate determination of emissions from prototype vehicles with diesel engines, was undertaken. The test vehicle was a 1972 Mercedes Benz 220 Diesel four-door sedan, equipped with automatic transmission. Testing has been by the 1975 Federal Emission Test Procedure, with the inertia set at 3500 lbs. There have also been some emissions tests under cruise conditions for sampling investigations. Comparison of the test emissions data with data from Mercedes diesels from other sources shows good agreement in CO and NO(x), when it is considered that different cars were tested in differnent laboratories. Data also indicates that the present CVS bag procedure is valid and reliable for determining CO and NO(x) emissions. The sampling method for hydrocarbons, however, needs to be refined.
