Single Parameter Engine Analysis and Performance Optimization of a Medium Duty Gasoline Engine

Failure analysis of an intake valve in a gasoline engine

This paper presents a failure analysis on a failed intake valve in a gasoline engine. During an endurance test, an intake valve was broken and caused some damages on the piston. Material examinations (by a light microscope and also a scanning electron microscope) were conducted on the fracture surface of the intake valve shaft. Results showed that no pores or defects could be observed and the m...

Performance and emission parameters analysis of gasoline engine with EGR

This paper presents an experimental investigation of various exhaust gas recirculation (EGR) rates on the engine performance like brake thermal efficiency, brake specific fuel consumption and brake power and engine exhaust gas emission parameters like nitrogen oxides(NOx), carbon monoxide (CO), hydrocarbon(HC) and particulate matter (PM) for the fuel used in the engine. Four observations are ma...

The Effect of Injection Timing and Phasing on the Emission of a Gasoline Single Cylinder Engine

Performance evaluation of Internal Combustion Engines (ICEs) and setting different emission standards has manifested the importance of pollution reduction as well as the optimal fuel consumption of these engines. Accordingly, the Engine Management Systems (EMS) are utilized which resulted in optimizing the power alongside the decrease in pollutant emission, through preparing the appropriate air...

Analysis of Recoverable Exhaust Energy from a Light-Duty Gasoline Engine

While EER (Exhaust Energy Recovery) has been widely pursued for improving the total efficiency and reducing CO2 emissions of internal combustion engines, the maximum regenerated power from the exhaust energy has been proposed and calculated in terms of endoreversible cycle. In this paper, based on the experimental data of an EER system installed on a light duty gasoline engine, the exhaust ener...
