Safe operation of dual-fuel engines using constrained stochastic control

Abstract: Premixed combustion strategies have the potential to achieve high thermal efficiency and to lower the engine-out emissions such as NOx. However, the combustion is initiated at several kernels which create high pressure gradients inside the cylinder. Similarly to knock in spark ignition engines, these gradients might be responsible of important pressure oscillations with a harmful potential for the engine. This work aims to analyze the in-cylinder pressure oscillations in a dual-fuel combustion engine and to de… Show more

“…8 In recent years, resonance excitation has been widely used for knock characterization 9 and to develop real time knock detection algorithms 10,11 and controllers. 10,12 In addition, resonance has been studied in 13 , where the resonance excitation intensity was controlled in a premixed dual-fuel engine. Moreover, resonance frequency has been recently used to estimate the trapped mass 14,15 by using signal analysis techniques.…”

“…Light-duty land vehicle engines typically use gasoline/ethanol as the LRF, 79 while marine engines typically usually use methane/natural gas, 10,11 and heavy-duty land vehicle engines have been used to study both of these primary fuel types, gasoline/ethanol, 12,13 and methane/natural gas. 1418 These are general only general trends; a wide variety of novel LRF’s have been studied in a wide variety of engine types, such as a gaseous dimethyl ether (DME)/propane mixture in a light-duty engine. 19…”
