Cooled EGR for a Turbo Charged SI Engine to Reduce Knocking and Fuel Consumption
Cooled exhaust gas recirculation is emerging as a promising technology to address the increasing demand for fuel economy without compromising performance in turbocharged spark injection engines. The objectives of this study are to quantify the increase in knock resistance and to decrease the enrichment and emission at high load. For this purpose four stroke turbo charged Spark Ignition engine (...
متن کاملModel Simplification and Observer Design of a Turbo Charged Engine
Tougher legislation and higher expectations on the comfort of the vehicles, forces the vehicle manufacturers to make progress. To manage the demands, it is crucial to correctly estimate the air mass-flow to the cylinders. To estimate the mass-flow, a mean value engine model (MVEM) could be used. Since the computational power in the controller system is limited, the original MVEM has to be modif...
متن کاملEmission Characteristics for a Homogeneous Charged Compression Ignition Diesel Engine with Exhaust Gas Recirculation Using Split Injection Methodology
Due to the serious issues caused by air pollution and global warming, emission regulations are becoming stricter. New technologies that reduce NOx and PM emissions are needed. To cope with these social exhaust gas regulation demands, many advanced countries are striving to develop eco-friendly vehicles in order to respond to stricter emissions regulations. The homogeneous charged compression ig...
متن کاملKnock Suppression Calculations In Highly Turbocharged Gasoline/Ethanol Engines Using Direct Ethanol Injection
Calculations are described of knock suppression using direct ethanol injection in spark ignition gasoline/ethanol engines. The calculations show that evaporative cooling from direct ethanol injection, coupled with the high octane rating of ethanol, can be highly effective in inhibiting knock, thereby allowing use of small turbocharged engines with substantially increased efficiency. The calcula...
متن کاملImaging and Analysis of Auto-Ignition and Heavy Knock in a Full Bore Optical SI Engine
The work involved a fundamental study of auto-ignition under unusually high knock intensities for an optical spark ignition engine. The single-cylinder research engine adopted included full bore overhead optical access capable of withstanding continuous peak in-cylinder pressures of up to 150bar. A heavy knock was deliberately induced under relatively low loads using inlet air heating and a pri...
