Emission characteristics of a single cylinder diesel engine with a swirl chamber were investigated. Specific fuel consumption, exhaust gas temperature, specific mass emissions of CO, total hydrocarbon (THC), nitrogen oxides (NO/sub x/), and particulates were measured. In addition, contents of carbon, hydrogen, CH/sub 2/Cl/sub 2/ soluble fraction (SOF), aliphatic hydrocarbons, polar organics, benzo(a)pyrene (B(a)P), and low temperature combustion fraction in the particulates, and the burnout temperature of the particulates were analyzed. All these results were represented as contour maps on a speed-torque plane. The emission of CO and the particulates increased steeply near the maximum speed and torque investigated, whereas the NO/sub x/ emission was almost independent of speed, increasing as the torque decreased. Content of hydrogen, SOF, aliphatic hydrocarbons, and low temperature combustion fraction showed similar patterns, having the maximum value at 1500 rpm at 1/4 load and decreasing toward 2500 rpm at full load. Burnout temperature of the particulate matter ranged from 673 to 707/sup 0/C and correlated with the carbon content.
