Physical and chemical phenomena responsible for odor formation in diesel engines. Interim progress report Jul 78-Dec 79
01 Jan 1980
Abstract
Two single cylinder diesel engine test facilities have been modified and instrumented for studying odor formation and control: a CFR prechamber (IDI) engine and a TACOM direct injection (DI) engine. A direct injection head and a 'Comet' type prechamber head for the CFR engine were obtained. Three laboratory burners were designed and built for this study: an air aspirated spray burner; a prevaporized burner; and a prevaporized, premixed, preignition flow reactor. Odor sampling and analysis techniques and procedures were developed and are being refined. Parametric odor studies of the engine and burner systems are underway. More than 990 odor samples have been collected and analyzed. Studies show that differences in peak pattern and intensity are observable with changes in odor level, fuel type, and experimental facility. Steady-state odor mapping indicates that the DI engine had higher odor emissions than the IDI engine in the current experiments. Changes in operating variables (speed, load, injection angle, etc.) over their normal operating ranges did not significantly affect odor emissions.
