Industrial investigations on IC engines rely largely on test-bench measurements. Some quantities such as residual burnt gas quantities due to valve timing are difficult to measure and are necessary to tune for maximum engine performance and minimum pollutants.
Here one-dimensional codes that compute the mass fluxes including the pressure pulsations in intake and exhaust manifolds are a useful tool to complete the information gathered on the engine test bench. Spray guided direct gasoline injection for stratified operation in partial load operation is a current topic to reduce fuel consumption in gasoline engines. Tuning injection and ignition in such operation modes requires an analysis of injection strategies and one-dimensional simulation codes provide the correct boundary conditions for the simulation of different spray types.
