The investigation of Spark Plug Position and number on the Spark Ignition Combustion performance
Due to the strict rules and regulations of environmental organizations on pollutant emissions control, the engine manufacturers are encouraged to develop new combustion systems that are compatible with the environment. Consequently, natural gas is being considered as one of the most outstanding alternatives between the fuels. In order to have a good combustion, mixture of air and fuel that enters into the combustion chamber must have acceptable speed and turbulence. Also, in order to create maximum power by the minimum amount of fuel, this mixture should be ignited at the right time and right place. Various researches have been conducted in order to compensate power loss caused by using natural gas rather than the conventional fuels. In this research activity, the open cycle engine simulation was performed to examine the influence of location of the spark plug on better combustion. This can occur when having better, stronger and more disciplined spark plug ignition. So, the position of spark plug can affect on the maximum temperature, pressure and also efficiency. 3D computational fluid dynamic modeling is used to simulate the D87 gas engine.
