Abstract
Spark-ignition internal combustion engines are sensitive to ignition time. The optimum ignition timing depends on speed, engine load and even fuel type. If this time is manipulated for any reason, it affccts on engine performance and combustion products and consequently the amount of pollutants. Due to the fuel crisis and the need to use engines with higher performance and lower fuel consumption, various strategies for reducing fuel consumption and increasing efficiency of internal combustion engines are presented. Since the XU7/JPL3, made by Peugeot, is the second high production engine in Iran, it has been selected in this investigation. The test results in full load condition show the ignition advance increment to a certain extent, increases power and NOx emissions relative to gasoline mode. The half load results indicate that the increment of the ignition advance angle reduces the brake specific fuel consumption, and NOx and HC emissions, whereas does not have any effect on CO emissions. Optimum amounts of the ignition advance in half and full load conditions have been presented for the gas engine.
