Using Mix of Gasoline and Liquefied Petroleum Gas for Lower Emissions and Greater Torque 2013-01-1151

The paper considers the problem of how to improve the economic efficiency of gasoline-powered internal combustion (IC) engines and at the same time increase their eco-friendliness and reduce emissions. Current industry thinking is that the use of alternative fuels (e.g. liquefied petroleum gas (LPG), which is widely used) helps reduce emissions of harmful substances in exhaust gases, but causes a reduction in engine power and torque. One of the ways to fix this problem is to add gasoline to the LPG, while current approaches to this problem improve either ecological performance or power readings of engines. It is assumed that one can change the fuel burning velocity and the amount of harmful substances in exhaust gases by adding gasoline to LPG and varying their percentage fuel mixture (called binary), thus providing higher ecological and operating performance of IC engines. Based on the above assumption a new engine control method has been developed, which improves gasoline IC engine performance and reduces emissions by adjusting the binary fuel composition and controlling the ignition advance angle. The paper presents the results of the experiments set up and examines the efficiency of the method developed.
