Driving pattern of gasoline passenger car was measured and analyzed at some areas (6 urban area routes, 4 radial routes, 4 circular routes) in Seoul city.
Measured items were vehicle speed, engine speed, intake manifold vacuum, and fuel consumption.
Driving pattern data were reappearanced with engine dynamometer. Results of this investigation might be summarized as below;
I. When we compared urban area route with radial or circular route in rush hour, it was found that the average vehicle speed was measured to be lower about 25% and fuel consumption to be higher about 12% in urban area route.
2. Average vehicle speed was measured to be higher about 30% and driving resistance output to be higher about 25% in non-rush hour, but average fuel economy was increased a little.
3. On the bases of average fuel economy and characteristics of exhaust emissions, optimum driving vehicle speed was found about 60 km/h in the 4th (top) and about 40 km/h in the 3rd in driving of experimental engine.
4. Idling frequency and exhaust emissions of CO, HC were related to idling closely.
But exhaust emission of NOx, which had nothing to do with idling frequency, had relation to acceleration time ratio.
