Abstract: (6 Views) |
In the present research, the parameters that needed to analyze engine performance and emissions have been analyzed. Considering the importance of improving combustion performance and reducing fuel consumption in spark ignition engines, the combined fuels of gasoline with ethanol and cobalt oxide nanocatalyst in a spark ignition engine have been analyzed. In order to reach a stable state in the stages of experimental tests, the temperature of engine water and oil before each test has reached the working temperature of the engine in the range of 90 0C, and to achieve this, the EF7 spark ignition engine at engine speed of 2800 rpm is around 10 Run the engine for 15 minutes until the various parts of the engine reach a stable state. The tests have been carried out under full load conditions and engine speed of 2800 rpm and torques between 0 and 100 N.m. Considering that by using the combined fuel of gasoline with ethanol and cobalt oxide nanocatalyst, the output power of a spark ignition engine, with gasoline base fuel, has increased, and on the other hand, fuel consumption has been reduced and in front of the pollutants as much as possible. Acceptance has decreased. The results of the current research in the aerospace industry, where power and fuel consumption are two important parameters for the design of rockets and jets, are significant and useful. |
