    Effect of Comprex Supercharging on Diesel Emissions
    (Pergamon-Elsevier Science Ltd, 2003) İçingür, Yakup; Haşimoğlu, Can; Salman, M. S.
    Diesel engine emissions are highly complex mixtures. They consist of a wide range of organic and inorganic compounds distributed among the gaseous and particulate phases. Particulates and NOx emissions are the important components of the Diesel exhaust. The composition of Diesel exhaust varies considerably, depending on engine type, operating conditions, fuel, and lubricating oil. In this research, the effects of supercharging, which is one of the engine operational parameters, on Diesel emissions have been investigated. For this purpose, a comprex, CX (pressure wave supercharger) was designed and manufactured and then matched to an indirect injection Diesel engine. During the engine tests, the emission parameters (CO, SOx, NOx and smoke density) have been observed and measured for different pulley ratios at full load conditions. The results showed that CX supercharging may be an alternative way of NOx reduction with some modifications. (C) 2002 Elsevier Science Ltd. All rights reserved.

    Impact of thermal barrier coating application on the performance and emissions of a turbocharged diesel engine
    (PROFESSIONAL ENGINEERING PUBLISHING LTD, 2008) Ciniviz, M.; Hasimoglu, C.; Sahin, F.; Salman, M. S.
    In this study, the effect of thermal-barrier-coated piston top and combustion chamber surfaces on turbocharged diesel engine performance was experimentally investigated. Satisfactory performance was obtained with TBC(1) (with coated cylinder head and valves) and TBC(2) (with coated cylinder head, piston top, and valves). Compared with a standard diesel engine, engine power was increased by 2 per cent, the engine torque was increased by 1.5-2.5 per cent, and brake specific fuel consumption (b.s.f.c.) was decreased by 4.5-9 per cent. The NO, emissions were increased by 10 per cent in diesel engines with TBC coatings compared with a standard diesel engine. Experimental studies have shown that there is a reduction in smoke emissions of up to 18 per cent as a result of TBC application.
