Abstract

The present work aims to introduce a new method to evaluate emission characteristics from vehicles al road test condition. The technique is characterized by introducing unique factors representing the equivalent toxic effect of the exhaust species. The method depends on measuring the concentration of exhaust species and calculating a factor called 'conditioned ton" taking into consideration the toxic weight of each species relative to CO. For this purpose, a series of measurements were carried out on a specified vehicle to prevent vehicle to-vehicle variation. The vehicle is equipped with an infrared gas analyzer and a magnetic pickup transducer to measure the concentration of exhaust constituents and engine rotational speed, respectively. The measurements were conducted at different vehicle speed and gearshift. The effect of spark timing and tire pressure was also examined. The results indicate that most of the carbon monoxide and unburned hydrocarbons emission appears at higher load as well as near the idling speed, which appears clearly as increase in the relative conditioned ton. The gearshift gives significant effect on the emission considering its analogy with engine load. Retarding the spark timing offers significant reduction in relative conditioned ton in spite of poor engine performance is experienced. It was found also that, the lower tire pressure exhibits significant increase in relative conditioned ton.
