Abstract
The paper deals with methodology for selection of Emission Control Devices (ECD), test matrix and evaluation procedure followed for vehicles, engines and analysis of test results.
In the present scenario, it is always being discussed that how existing vehicles and engines manufactured in India complying to Euro I /Euro II standard will perform with different sulphur percentage fuel. The emission control device such as Oxidation Catalytic Converter (OCC) is not very commonly used on the Euro-II vehicle and heavy-duty commercial vehicles. The performance of diesel oxidation catalyst on different sulphur percentage is of vital importance in Indian scenario. The particulate matter is always a concern in diesel vehicles and engines and most of Indian vehicles are having very low margin for particulate matter vis-à-vis regulation.
Considering above, a comprehensive study by ARAI is undertaken with the objective to compare emission characteristic of diesel 3 wheeler vehicle, utility vehicle, heavy duty engine and tractor engine with fuels having different sulphur content of 50 ppm, 150 ppm, 300 ppm and 500 ppm.
The above engine and vehicles were installed with diesel oxidation catalyst, which is specially supplied by ECD manufacturer taking into account engine characteristics in terms of emission and performance. The set of engine and vehicles were subjected to evaluation with particulate trap specially designed and optimized to ascertain the performance with fuel having different sulphur content of 50 ppm, 150 ppm, 300 ppm and 500 ppm. Some vehicles were also subjected to evaluation with combination of oxidation catalyst and particulate trap.
The study could establish the methodology and limitations of installation of ECD on vehicles. The parameters such as temperature and backpressure before and after ECD were monitored during test program, which gave technical inputs to ascertain the behaviour and effectiveness of ECD.
