The regulation for hydrocarbon emissions from vehicles have become much more stringent in recent years. These more stringent regulations request vehicle manufacturers to develop the exhaust system for reducing exhaust emissions. The exhaust emission has many sources in vehicle. In order to investigate the hydrocarbon(HC) in the exhaust port, concentrations of individual HC species were measured in exhaust process. using sampling valve, the light hydrocarbon emissions were captured in the exhaust port(catalyst before and after)and analyzed from LPLi engine exhaust port(catalyst before and after) by using different fuel properties. Then exhaust samples were measured by gas chromatography(GC) and exhaust gas analyzer. Catalyst conversion efficiency for different fuel properties of Butane 100% was better than Propane 100%.

This paper is the investigation on the effect of vehicle speed control to match driving trace automatically using application SW of ECU through simulation. For emission driving test, it needs numerous tests to get reliable result because of driver’s deviation even if driver is same person. In case of automatic control by application SW of ECU, it is easy and simple. Also it reduces time to get more effective result on complicated driving trace. To apply automatic control system, it designs PID system to control acceleration and deceleration by application SW and CAN communication. These methods are operated and confirmed by simulation of SILS. As a result of SILS, the virtual vehicle speed is matched entered WLTC driving cycle in ECU. And the vehicle speed deviation is satisfied with standard of permission.
