Abstract
The report describes the design and testing of a high energy timed spark discharge starting aid for use on a single cylinder direct injection Diesel engine. The system developed was successfully used to start the engine in ambient temperatures down to -50C with the engine cold soaked for 24 hours at that temperature and 8.5 V applied to the starter. Three grades of commercial Diesel fuels and a "1990" Diesel fuel were used in the starting tests. The minimum starting temperature for each fuel was found to be at or slightly below the pour point of each fuel when using the timed spark discharge aid or an electrically heated glow plug installed in the same spark plug hole. The timed spark system consumed about 50 W, while the glow plug consumed 108 W and required a one minute preheat. Cranking times up to 30 s were required with the timed spark system while the glow plug usually produced starts under 5 s cranking. TRUNCATED
