Fumigation of a diesel engine with low Btu gas
A 0.5 liter single-cylinder, indirect-injection diesel engine has been fumigated with producer gas. Measurements of power, efficiency, cylinder pressure, and emissions were made. At each operating condition, engine load was held constant, and the gas-to-diesel fuel ratio was increased until abnormal combustion was encountered. This determined the maximum fraction of the input energy supplied by the gas, E/sub MAX/, which was found to be dependent upon injection timing and load. At light loads, E/sub MAX/ was limited by severe efficiency loss and missfire, while at heavy loads it was limited by knock or preignition. Fumigation generally increased ignition delay and heat release rates, but peak pressures were not strongly influenced. Efficiency was slightly decreased by fumigation as were NO/sub X/ and particle emissions while CO emissions were increased.
