“…In the diesel engines, particulate and NOx emissions are very important parameters [1,4]. For the LHR engine, the effects of particulate emissions have already been published in another paper [16] by the present author and his colleagues.…”

“…This efficiency is 8% better at high speeds. Alkidas et al [1] determined that thermal efficiency of the engine with 0.5 mm ceramic coated piston was 10% better than baseline. But, thermal efficiency of the engine with 1 mm ceramic coated piston was lower 10% than baseline.…”

“…BMEP is directly proportional to torque which indicates the engine's ability to do work. Assanis et al [1] investigated that the variations in BMEP with engine speed at full load for 1 mm and 0.5 mm coating thicknesses. The rise in BMEP, as engine speed decreased, results from the increased burned fraction prior to top dead center (TDC), which was realized with longer times between the start of injection and TDC.…”

-In this study, an experimental study of the effects of injection timing on nitrogen oxide (NO x ) emissions of a low heat rejection (LHR) Turbo charged direct injection diesel engine was conducted. The injection timing and brake specific fuel consumption (BSFC) trade-off must be considered together in performance and NO x emissions analysis. For the original injection timing of the 20 • before top dead centre, the brake Specific fuel consumption value of the LHR engine was approximately 6% lower than the original engine. NO x emissions were also higher (about 9%) than the original engine. To reduce NO x emissions released by diesel engines, the method of injection timing retard was utilized. Thus, the LHR engine was tested for two different injection timings; 18 • and 16 • crank angle before top dead centre (BTDC), at the same engine speeds and load conditions. The results showed that the BSFC and NO x emissions were reduced 2% and 11%, respectively by retarding the injection timing. Optimum injection timing for the LHR engine was obtained through decreasing by 2 • BTDC.

SUMMARYThe urban air pollution is a very complicated problem. The exhaust emissions from internal-combustion engines account for a major portion of this problem. It is realized that the content and concentrations of the exhaust emissions depend on various parameters. These parameters include engine design parameters, operational parameters, exhaust gas aftertreatment, fuel types, fuel additives and lubricants. The present review paper discusses the effect of some parameters on the emission level and characteristics from internal-combustion engines. The paper begins with an introduction of general information on the nature of emissions of exhaust gases, including the toxicity and causes of emissions for both spark-ignition and diesel engines. The paper then shifts to an up-to-date information of the published research work on the subject matter.1998 John Wiley & Sons, Ltd.
