Emissions Generated from a Suzuki Liane Running on Unleaded Gasoline and LPG under the Same Load Conditions 2008-01-2637
Green fuels or alternative fuels are growing fast now days and can be used in every passenger car but also in many commercial vehicles. In various countries all around Europe such as Italy, Netherlands and Belgium LPG is a reasonable alternative fuel for small and medium cars. This study evaluated the performance of a Suzuki Liane fitted with a multipoint in-line gas fuel injection system. During the tests various exhaust gasses (CO, CO2, NOx, O2 and HC) and temperatures were measured in different load condition on a chassis dynamometer. All tests were conducted in the engines laboratory at Karel de Grode Hogeschool (KDG) in Antwerp, Belgium. The car was tested on a chassis dynamometer similar to the one described in , ,  and various loads were applied at different gear settings.
All measurements were taken under full load and four different gears (2nd gear, 3rd gear, 4th gear and 5th gear) were selected in the gear box. Exhaust gas emissions were measured under each of those conditions, data collected from the analyzers, calculated, tabulated and plotted. Graphs and emissions comparison for both fuels are presented and discussed in this paper.
For each test the evaluation was made in terms of the performance of the engine running on gasoline and LPG under the same load conditions. Scoop images collected and lots of sensors were installed on the engine in order to collect more data (engine cooling water and oil temperature, air intake temperature etc). Comparison with the different values of the original gasoline Electronic Control Unit and the LPG control unit was made. Special attention was given those tests where the exhaust gases temperature on vehicle running on LPG was higher compared to those running on unleaded gasoline. This paper discusses all factors influenced from that and also analyzes the factors affected the exhaust gas temperature of the vehicle running on LPG as it is higher than that running on gasoline in different load conditions and lower in the other. This study addresses all the above and clear answers can be obtained.
