We propose a delay-dependent sampled-data output-feedback LPV control technique to address the air-fuel ratio (AFR) regulation problem in spark ignition (SI) engines. AFR and advanced fueling strategies are essential for maximizing fuel economy while minimizing harmful exhaust emissions. The path of SI engine, as well three-way catalyst (TWC) simplified dynamics, have been captured by continuou...
Spray ignition and flame stabilisation in the frame of diesel-like combustion conditions combine fundamental and complex physical and chemical processes. In this work, a numerical investigation has been performed to evaluate the potential of integrating detailed chemistry into CFD calculations, in order to improve predictions and gain more insight in involved processes. This work has been carri...
Engine performance depends on two main factors of engine speed and ignition time. Ignition timing can affect engine life, fuel economy and engine power. In this paper, to study engine performance of Peugeot 206 TU3A with comparison ratio of 10.5:1 and displacement of 1361CC in MATLAB software, a two-zone burned/unburned model with the fuel burning rate described by aWiebe function was used for ...
The influence of square corners on the ignition of a solid exposed to a step in surface temperature is analyzed by means of large activation energy asymptotics. This study begins by considering the case of a semi-infinite square corner, applicable to the ignition of finite bodies with square corners when the reaction is very fast. Two spatial zones (reactive and inert) and two time stages (init...
Composite solid propellants are materials that constitute from an oxidizer, an organic binder, a metallic fuel, additives and etc. Nowadays the size of energetic particles is attended because of their functional profits. Size reduction is well known way to increasing reactivity of additives in propellant formulations. Nanoparicles have considerable effects on composite solid propellants propert...
The pyrolytic and oxidative behaviour of the biofuel 2,5-dimethylfuran (25DMF) has been studied in a range of experimental facilities in order to investigate the relatively unexplored combustion chemistry of the title species and to provide combustor relevant experimental data. The pyrolysis of 25DMF has been re-investigated in a shock tube using the single-pulse method for mixtures of 3% 25DMF...
This study aims at modeling the effect of incoming heat flux fluctuations on solid material ignition. In order to propose a general methodology that can be applied to any kind of solid target, kernels accounting for the target temperature response regarding an incoming heat flux are developed for thermally thick and thin solids with low or high thermal inertia. The expected behavior of these di...
