| Abstract |
An effective approach for improving fuel
economy and reducing emissions is to employ a down-sized,
turbocharged internal combustion engine (ICE). However,
turbocharged engines exhibit a relatively low torque
capability at low engine speeds. To overcome this problem,
an electrical torque boost may be applied whilst accelerating
and changing gear, and to facilitate energy recovery during
regenerative braking. The paper describes the operational
requirements of such a torque boost system, which employs
a supercapacitor energy storage buffer, outlines the design
and sizing of the electrical machine, and presents test results
from a demonstrator system. |
