    Exhaust gas analysis of an eight cylinder gasoline engine based on engine speed
    (Elsevier Ltd, 2017) Kılıçarslan, Ali; Qatu, Mohamad S.
    In this experimental work, exhaust gas analysis of an eight cylinder and v-type gasoline engine, namely, a Chevrolet 5.7, is experimentally performed in terms of engine speed at laboratory conditions by using of an exhaust gas analyzer and the special software called "NetDyn" and "WinDyn". The engine test setup includes a dynamometer to determine the engine torque and data acquisition system. At the experimental works, the engine speed ranges from 2500 rpm to 5250 rpm and step time for successive speeds is held constant as 10 s. A throttle position of 60 is selected for the engine operation. Exhaust gas emissions such as O2, CO, NOx and SO2, are measured in terms of engine speed. Exhaust gas temperature and excess air coefficient are also measured as a function of the engine speed during the experiments. © 2017 The Authors.

    Performance investigation of an eight cylinder gasoline engine
    (American Society of Mechanical Engineers (ASME), 2014) Kılıçarslan, Ali; Qatu, Mohamad S.
    Performance investigation of a Chevrolet 5.7, eight cylinder gasoline engine is experimentally carried out at laboratuary conditions by means of the special softwares called "NetDyn" and "WinDyn". This experimental work is intended to make contribution to the researchers that experimentally analyze the parameters of gasoline engines with the engine speed in detail. During the experiments, the engine speed is changed from 2500 rpm to 5250 rpm with 250 rpm intervals and steptime for succesive speeds is kept constant as 10 s. Engine power, engine torque, fuel and air flowrates per kW, mechanical efficiency, oil temperature and pressure, break mean effective pressure and exhaust temperatures are measured as a function of engine speed. As the engine speed was increased, it was observed that the air mass flow rate, exhaust and oil temperatures increased while the break mean effective pressure, mechanical volumetric efficiency, and engine torque decreased. Engine power increased between the engine speeds of 2500 rpm and 3750, but it decreased between the speeds of 3750 rpm 5246 rpm. Copyright © 2014 by ASME.
