Abstract:

Considering the disadvantages of gasoline and natural gas as mono-fuel in SI engines has made the researchers to improve the performance and reduce the pollutant as the advantages of the application of dual fuel engines. On the other hand, lean-burn in engine may lead to the reduced pollutant. In the present study various mixtures of gasoline and natural gas with the gasoline as the dominant fuel, including 100‎‎ ‎‎‎%‎‎‎, 87,5%, 75‎‎% and 62.5% in weight-base gasoline and the rest natural gas (respectively named as G100, G87.5, G75, G62.5) in lean-burn condition with 0.9 as the equivalence ratio are investigated. At 1800 rpm and 11 compression ratio, cylinder pressure variations of 350 successive cycles of each mixture were recorded using a single cylinder research engine. First of all, the raw data were processed and the optimized knock-free advance for each individual mixture was determined. Later on the performance of all four mixtures in the corresponding optimized advance was explored. The results revealed that by increasing the amount of natural gas in the mixture, the CO pollutant reduced however the amount of HC initially increased which was followed by a decreasing trend. The amount of NOx had a direct relation with the appearance of the natural gas. In the lean-burn condition, a better performance was observed for G75 in compare with G100 and the other mixtures.

Experimental Study of Performance of Spark Ignition Engine with Gasoline and Natural Gas

The tests were carried out with the spark timing adjusted to the maximum brake torquetiming in various equivalence ratios and engine speeds for gasoline and natural gas operations. In thiswork, the lower heating value of gasoline is about 13.6% higher than that of natural gas. Based on theexperimental results, the natural gas operation causes an increase of about 6.2% brake special fuelconsumpt...

An Experimental Study on the Effects of Bioethanol-Unleaded Gasoline Blends on Engine Performance in a Spark Ignition Engine

In the present study, the effects of bioethanolunleaded gasoline blends on engine performance were investigated in a spark ignition engine. Fuel containing 100% ethanol (E100), fuel blend containing 40% bioethanol by volume (E40) and 100% unleaded gasoline (E0) were tested and the test results were compared. As the result of the study, it was found that the use of unleaded gasoline and bioethan...
