Model-Based Control of Gasoline Partially Premixed Combustion
Partially Premixed Combustion (PPC) is an internal combustion engine concept that aims to yield low NOx and soot emission levels together with high engine efficiency. PPC belongs to the class of low temperature combustion concepts where the ignition delay is prolonged in order to promote the …

Characterization and Control of Multi-Cylinder Partially Premixed Combustion
In the last decade diesel combustion has developed in a new direction. Research has been carried out trying to prolong the ignition delay and enhance fuel/air premixing to avoid diffusion combustion as well as lowering the combustion temperature through use of EGR. One of these new combustion …

Turbulent combustion simulation in realistic gas-turbine combustors
… and efficient numerical modelling of turbulence combustion with an emphasis on an industrially representative Tay model combustor. This combustor retained all essential features of a modern aero-engine rich burn combustor and thus the turbulence combustion within this combustor is much more …

Low Temperature Combustion and Emissions of Diesel with Additions of N-Butanol in a Direct Injection Compression Engine
… study. The research is focused on producing a partially premixed combustion by means of an original injection strategy. This strategy is based on introducing an early injection of n-butanol in the intake manifold at the start of the intake stroke, followed by a conventional injection close to …
