| Abstract:On the basis of only minor modification to the basic structure of a gasoline engine, the original single spark plug ignition was transformed into a double spark plug ignition. And three-dimensional simulation and experimental verification were carried out. Then, a comparative analysis of three different modes of using spark ignition, double spark synchronous and asynchronous ignitions was made. The results of the tests show that at the speed of 6500 r/min and under full load conditions, the best ignition advance angle for the single spark ignition is 29° in crank angle with an excess air ratio of 1.00, and for the double spark synchronous and asynchronous ignitions, the corresponding advance angles are 22°and 22°/24°, respectively, with an excess air ratio of 1.15. As observed, use of double spark asynchronous ignition allows the engine to have the best overall performance. Compared with the single spark ignition, it can increase the available work by 8.49%, and compared with the double spark synchronous ignition, it can improve available work by 3.60% with the reduction of burst pressure and compression work, and hence exhaust emissions. In the above tests, the engine is always controlled to operate in the non-detonation zone. |
