Title:
TORQUE CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2008/156157
Kind Code:
A1
Abstract:
When a compression ignition type internal combustion with a centrifugal supercharger is
operated under low atmospheric pressure, a decrease in torque produced by the
engine is minimized as much as possible. To achieve this, when the engine is operated
under low atmospheric pressure, a fuel injection valve performs after-injection
to minimize a decrease in supercharge pressure. In this process, the timing
of the after-injection and/or the amount of the after-injection can be feedback-controlled
based on a difference between an actual supercharge pressure and a target supercharge
pressure.
