With the stringent emissions regulations for spark ignition engines, attention has always been paid to the cold-start emissions of hydrocarbons and carbon monoxide. The engine speed is an external parameter that can reflect the combustion quality. In this paper, a four-cylinder spark ignition engine fuelled with gasoline and methanol-gasoline blends with methanol fractions of 10%, 30% and 85% is studied; the cold-start transient performances are investigated at ambient temperature of 15°C, -7°C, -15°C and -25°C respectively. The engine speed curves indicate the existence of misfire cycles and incomplete combustion cycles, which are proved by the measured in-cylinder temperatures and the data on the indicated mean effective pressure. The experimental results show that the addition of methanol increases the starting time at low temperatures, which improves the combustion, however. The engine started successfully for all the blending ratios and ambient temperatures except for the 85% methanol-gasoline blend at -25°C. During the cold-start process, the peak speed and the transient period increase with increasing methanol fraction, while the speed fluctuations decrease. Thus the addition of methanol improves the cold-start performance of the engine.

Effects of Methanol/Gasoline Blends on a Spark Ignition Engine Performance and Emissions

Three typical methanol-gasoline blends M10, M20, and M85 containing 10%, 20%, and 85% of methanol by volume, respectively, were used to investigate the effects of different methanol/gasoline ratios on engine power, thermal efficiency, and emissions, especially the exhaust methanol emission. A three-cylinder, port fuel injection engine was applied. Experimental results show that the engine power/torque ratio under the wide open throttle condition mainly depends on the amount of heat delivered to the engine. The addition of methanol significantly improves the brake thermal efficiency, while the methanol/gasoline ratio has a slight effect on it. Engine out CO and NO x emissions decrease with the increase of the methanol/gasoline ratio. The use of M85 leads to a reduction of CO and NO x by about 25% and 80%, respectively. A gas chromatograph is calibrated and used to measure the methanol emission. Measurement indicates that the addition of methanol in gasoline results in an increase of the unburnt CH 3 OH emission. And its concentration is nearly logarithmically proportional to the cyclically injected quantity. Because the response of the flame ionization detector to methanol is 40% that of hydrocarbon, the total hydrocarbon emission of the engine is revised. The nonmethanol hydrocarbons that resulted from gasoline are less affected by methanol addition, while the methanol emission is controlled independently by the cyclic quantity of fuel methanol injection.
