Принадлежит: Honeywell International Inc

A turbocharger system for an air-throttled engine includes a variable flow expander (VFE) in the intake air conduit system that supplies intake air to the engine. At part-load operation, the VFE expands the air by an amount that is controllable, and thus regulates the air flow as needed by the engine. The power extracted by the VFE from the intake air flow is fed to the turbocharger, which helps to achieve quicker turbocharger response and improve scavenging of exhaust gases from the engine. The VFE can be a variable expansion ratio turbine.

Turbocharger operation to increase brake effectiveness

Номер: US20140216398A1

In response to activation of a compression release brake when a motor vehicle having a turbocharged internal combustion engine is operating at some elevation above sea level and a turbocharger compressor is operating in a region of an operating map which is creating boost air in an engine intake manifold which would cause the compression release brake to decelerate the vehicle more slowly at that elevation than it would at sea level for the same operating conditions of the vehicle and engine other than altitude, the compression release brake decelerates the vehicle less slowly by operating a valve mechanism to reduce flow through a charge air cooler and increase flow through a charge air cooler by-pass.
