|Ignition Issues and Their Impact on Engine Performance, Efficiency and Emission|
|I.D. #||C0131||Duration||2 Days|
| Improved understanding and control of ignition and thereby combustion are critical in dealing with the problems of pollutants formation, engine performance, and fuel economy. This seminar will provide you with basic knowledge and recent advances in combustion-initiation (ignition) issues to more intelligently evaluate and harness their potentials. Thermodynamic and fluid mechanical properties of the unburned charge near the spark plug and at the time of ignition strongly affect the quality of the combustion and therefore the emission of the pollutants from the engine. Furthermore, a weak ignition limits engine performance and drivability. The so-called cyclic variability, which affects and bounds the lean and knock limits of an engine design is to a great degree influenced by the ignition system. Equally important, the ignition system can and is being used to provide local in-cylinder information on air-fuel ratio, misfire, knock, and mass fraction burned in each individual cylinder. Hence, great potential exists for applications of this information for individual cylinder control strategy to attain a more fuel efficient and environmentally compatible engine.
| By attending this seminar, you will be able to:
performance, efficiency, and emission
conditions on combustion and emission
ignition-based engine diagnostics
chamber design and low engine emission of pollutants
|Who Should Attend|
| This seminar will be especially valuable for engineers, technical and project managers, researchers, and academicians involved in ignition and combustion/emission aspects of the combustion engines. Currently, the design strategy of many components in these engines is affected by combustion and emission control measures to meet customer's, federal and local government's demands and regulations. Therefore, engineers working on the design of components for high efficiency and performance of combustion engines as well as those directly and indirectly involved in ignition and emission reduction strategies will highly benefit from this seminar.
