Effect of Coal to Liquids on Real Road Emission Characteristics of Diesel Bus

Abstract:

The real road emissions characteristics of particulate matters (PM) and NO_X were researched based on velocity and acceleration of a typical China IV diesel bus which was fueled with five different fuels, including pure China IV diesel, pure coal to liquids (CTL), different blends of China IV diesel and CTL, of which the blend ratios of the CTL were separately 10%, 20%, 50% with the use of OBS-2200 and Engine Exhaust Particle Sizer (EEPS 3090). The research showed that the NO_X and PM emissions of bus fueled with five different fuels all show a gradual increase with the increase of velocity and acceleration. The CTL mixed with diesel can effectively reduce the NO_X emission, and the higher ratio of CTL, the more effective of reduction. The CTL mixed with diesel can reduce PN emissions for both nuclei modes and accumulated modes and reduce the peaks of PN emissions for accumulated modes so that reduce the PM emissions, the higher ratio of CTL, the more effective of reduction.
