The extremum seeking controller (ESC) that minimizes the unknown performance index is applied to the control of SI (spark ignition) engines in the idle speed region. The proposed control system consists in the three parts, fuel-jet mount controller, ignition-timing controller and engine speed controller. The ESC applied to the engine speed controller should be modified in order to improve the e...

In this paper, we present a high-speed RFID data filtering engine designed to carry out filtering under the conditions of massive data and massive filters. We discovered that the high-speed RFID data filtering technique is very similar to the high-speed packet classification technique which is used in highspeed routers and firewall systems. Actually, our filtering engine is designed based on ex...

To improve the responsiveness of engine speed control to disturbances, robust controls were investigated by simulation. The intake air control system of a gasoline engine is a typical nonlinear system, and the disturbances and parameter perturbations are generally regarded as being the unstable factors with regard to engine control. In this paper, a Mean-Value Engine Model (MVEM) with disturban...

at the present work, the effect of cold exhaust gas recirculation (egr) on combustion and pollution of a dual fuel engine has been investigated by cfd code fire. the turbulent flow within the combustion chamber is simulated using the k-ε turbulence model, which is modified for engine flows. “wave” and “eddy break up” models are employed to predict combustion and spray process. the calculations ...

in this paper, the effect of bioethanol- gasoline fuel blends on exhaust emissions of a four-cylinder spark ignition (si) engine was investigated experimentally. pure gasoline fuel was blended with various percentages of bioethanol (0, 20, 40, 60 and 85%), and the hc, co, co2 and nox exhaust emissions were measured at different engine speeds and two throttle valve positions (full throttle and 5...

The presented control scheme utilizes Adaptive Neuro Fuzzy Inference System (ANFIS) controller to track a reference engine rotational speed and disturbance rejection during engine idling. To evaluate the performance of the controller a model of the engine is simulated and simulation results presented. ANFIS implements a first order Sugeno-style fuzzy system. It is a method for tuning an existin...
