Turbocharging Concepts for Downsized DI Gasoline Engines

Highly Turbocharging a Flow Restricted Two Cylinder Small Engine - Turbocharger Development

“…It is noted that increased CR and or MAP is expected with the implementation of various knock preventive strategies. These strategies could include direct injection (DI), exhaust gas recirculation (EGR), intake charge cooling (intercooling and/or evaporative), combustion enhancement through chamber design and increases in fuel octane number [14,15,16,17,18,19]. However, trends confirm that for a given CR and MAP condition, knock is less prone at higher engine speeds [13,20].…”

Experimental Study on Turbo-Matching of Turbo-Charger B60j68 for Commercial Vehicle Engine

“…That is, their combination to be optimized at full load. The trial and error method cannot be adopted in this case because the matching is directly affecting the engine performance [5], [20], [21]. So it is a difficult task and to be worked out preciously.…”

“…[1]- [5]. Due to the character of centrifugal compressor, the turbocharged engine yields lesser torque than naturally aspirated engine at lower speeds [6], [7].…”

Experimental evaluation of Turbo-Matching of B60j67, B60j68 and A58n75 Turbochargers by Data-logger Method

“…That is, their combination to be optimized at full load. The trial and error method cannot be adopted in this case because the matching is directly affected as well as affects the engine performance [5], [20], [21]. So it is a difficult task and to be worked out preciously.…”

“…Turbo charger also helps to reduce specific fuel consumption (SFC), downsizing the engine, reduce CO 2 emission, etc., [1]- [5]. Due to the character of a centrifugal compressor, the turbocharger with engine yields lesser torque than naturally aspirated engine at lower speeds [6], [7].…”
