Temperature Calculation Methodology of Pre Chamber With Homogeneous Charge 2019-36-0203
The methodology for temperature calculations of homogeneous prechamber must be analyzed from a one-dimensional analytical model so that it is possible to determine the temperature profiles during the filling and emptying of the gases, so that it can avoid abnormalities such as increase of Forces, deformation / breaking, performance limitations, increased probability of detonation, increase of NOX and increase in the probability of pre-ignition. The equations of conservation of energy and of the state of gases are used to base the calculations, following the hypothesis that the flow is transient, comprehensible and one-dimensional; The fluid in the control volume is in the gaseous state and the fuel is already injected into the gas phase following the ideal gas equation. A homogeneous mixture is considered to generate a poor mixture in the pre-chamber.
