Characteristics Of Cold Start Of A Diesel Engine Using Jp8 And Ulsd Fuels, Madhushankar Palanisamy
Characteristics Of Cold Start Of A Diesel Engine Using Jp8 And Ulsd Fuels, Madhushankar Palanisamy
Wayne State University Theses
This study involves the cold start testing of ULSD and JP8 fuels on the 6 cylinder 7.2 liter turbocharged diesel engine at various ambient temperatures as low as 0oF for JP8 fuel and 10oF for ULSD fuel. Cycle by cycle analysis of the cold start transient data, along with the effects of variation in ambient temperature on the engine cranking speed and in cylinder motoring pressure were analyzed and presented. It was found that the reduction in ambient temperature resulted in prolonged cranking periods along with the longer time taken to reach idling speed as well as increased combustion instability. …

Ion Current Signal Detection During Cold Starting And Idling Operation In A Diesel Engine, Sanket Anil Gujarathi
Wayne State University Theses
Cold starting of diesel engines is characterized by inherent problems such as long cranking periods and combustion instability leading to an increase in fuel consumption and the emission of high concentrations of hydrocarbons which appear as white smoke. Accordingly, a signal indicative of combustion during cold starting and idling operation is important for combustion and emission control. The ion current signal has been considered for the feedback control of both gasoline and diesel engines. However, the ion current signal produced from the combustion of the heterogeneous charge in diesel engines is weaker compared to that produced from the combustion of …
