CHARACTERISTICS OF EXHAUST EMISSIONS FROM HEAVY DUTY GASOLINE POWERED VEHICLES

This report describes exhaust emissions from six heavy duty gasoline powered vehicles. Emission tests were performed on chassis-dynamometer under the six mode cycle, four kinds of driving cycles with different average vehicle speeds and several kinds of operating conditions of cruising, acceleration and deceleration. Cvs was used to measure mass emission over the driving cycle and a direct sampling method was applied in the other emission tests. Test data on carbon monoxide, hydrocarbon and oxides of nitrogen are given and analyzed to average exhaust concentration, mass emission, mass emission rate and emission factor. Exhaust emission concentrations on cruising, acceleration and deceleration were of a similar level to passenger cars, however, exhaust volume and mass emission were considerably higher than passenger cars. Mass emission in grams per kilometer tends to reduce with the increase of average vehicle speed. Emission factor in grams per fuel-litre and mass emission rate in grams per ps-hour or grams per ton-kilometer are relative to average exhaust concentration. /Author/TRRL/
