Control of automotive exhaust emission has become an important research area to meet the more stringent automotive emission regulations. Beside the modification on internal combustion engine, control engineering is seen as another approach to improve and meet these requirements. This paper focuses on the design and development of a control system to reduce the harmful waste of automotive exhaus...

Observer Design for Downsized Gasoline Engine Control Using 1D Engine Simulation — This study presents the use of a 1D engine model for the control design of a twin-scroll turbocharged gasoline direct injection 2.0 l i4 engine with twin camphaser. This virtual engine is used for the development of the in-cylinder mass observer which is a crucial issue for the control of such an engine because o...

Biofuel, a form of renewable fuel, has promising future, especially as the alternative fuel for transportation. Biofuel is usually blended with petroleum fuel and used in flex fuel engines. Since the characteristics of biofuel are quite different from those of the petroleum based fuel, it is very important to optimize the combustion properties for biofuel engines under different fuel blends. Th...

This article makes the argument that compression ignition combustion processes that are “flameless” with volumetric energy release, described as Low Temperature Combustion (LTC), are a thermodynamic pathway to maximizing the efficiency of reciprocating piston, internal combustion engines. The argument is built from the foundation of determining the maximum theoretical efficiency for an IC Engin...

As emission standards continue to evolve, it is clear that future engine control strategies will involve the integration of combustion optimization, fuel refinement and advanced exhaust after-treatment technologies. The West Virginia University (WVU) Center for Alternative Fuels Engines and Emissions (CAFEE) continues to engage the challenge of future regulation in a multi-pronged approach, inv...

Improvements in hybrid electric vehicle fuel economy with reduced emissions strongly depend on their supervisory control strategy. In order to develop an efficient real-time supervisory control strategy for a series hybrid electric bus, the proposed equivalent fuel consumption optimal control strategy is compared with two popular strategies, thermostat and power follower, using backward simulat...

Abstract Over the decade, due to the fact that the global energy resources are in deadly shortage, much emphasis is put on the energy consumption in thermal power throughout the world. Following developed is Circulating Fluidized Bed Boiler (CFBB) in recent years, a kind of combustion boiler that can clean and desulfurize the coal efficiently in the combustion process.Circulating Fluidized Bed ...
