Internal Combustion Engine
PI: Lin-Shu Wang
Prof, Wang is the inventor of Turbo-Cool turbocharging system, which utilizes the expansion of charge exhaust from internal-combustion piston engine in exhaust-charge- driven turbine to achieve higher engine effective expansion ratio in a straightforward manner. The novelty of the concept is that the excess power from higher charge expansion through turbine (rather than being considered as an object for power recovery, as in the classical turbocompound concept) is used for conditioning intake charge-air-for the purpose of engine-loss reduction and, simultaneously, engine power gain, Variable geometry turbine (VGT) turbochargers are used in Turbo-Cool turbocharging systems. The temperature of Turbo-Cool conditioned charge-air is around or even-below ambient air temperature. Thus, the perception of the knock-prone tendency of turbocharged gasoline engines due to their higher charge-air temperature is dispelled. Turbo-Cool turbocharging systems, in an indispensable partnership with VGT turbochargers, produce engine performance for internal combustion gasoline engines of unsurpassed torque and power with excellent torque back-up, as well as improved engine-efficiency.
