Turbo-charging apparatus for vehicle engine

Номер: US20120000196A1
Принадлежит: Mazda Motor Corp

The disclosure provides a turbo-charging apparatus for a vehicle engine, which includes a first and second turbocharger, an inter-turbine passage connecting a discharging port of a first turbocharger turbine with an introducing port of a second turbocharger turbine, a bypass passage connecting an introducing passage of the first turbocharger turbine with the inter-turbine passage, and a control valve for opening and closing the bypass passage. The inter-turbine passage extends substantially straight from the discharging port of the first turbocharger turbine toward the second turbocharger when viewed from a direction parallel to turbine shafts of the first and second turbochargers, which are arranged substantially parallel to each other, so that the inter-turbine passage connects with an outer circumferential part of the second turbocharger turbine so as to extend in a direction tangent to an outer circumference direction of the second turbocharger turbine.

Exhaust gas throttle valve

Номер: US20130199176A1

A method for driving exhaust gas recirculation comprising the steps of restricting exhaust gas flow into the turbine inlet to create backpressure in the exhaust system under low engine operating conditions, and providing an unrestricted exhaust gas flow to the turbine under normal engine operating conditions. Restriction of exhaust gas flow is accomplished through the use of an exhaust gas throttle valve disposed upstream of the turbine inlet. The valves can be adjustable knife edge flap valves or D-shaped valves situated in each passageway of a divided exhaust manifold, which are closed to varying degrees to generate desired levels of backpressure while allowing exhaust gas to pass though open regions of the partially obstructed flow pathway to reach the engine turbocharger. This allows the turbine to continue to spin, while at the same time exhaust gas back pressure upstream of the turbocharger is used to drive exhaust gas recirculation.

Fuel Injection Strategy for Internal Combustion Engine Having Dedicated EGR Cylinders

Номер: US20130220286A1
Принадлежит: Southwest Research Institute SwRI

A method using exhaust gas recirculation (EGR) in an internal combustion engine. The engine has at least one “dedicated EGR cylinder”, whose entire exhaust is recirculated back to all the engine cylinders. The dedicated EGR cylinder is operated at a rich air-fuel ratio, and the other cylinders are operated stoichiometrically so that a conventional three way catalyst may be used to treat the exhaust. A fuel injector is used to inject fuel into the combustion chamber of the dedicated EGR cylinder after initiation of the main combustion event. This post injection method overcomes flammability limits of a dedicated EGR cylinder, and increases the hydrogen (H2) and carbon monoxide (CO) in its exhaust.

An object of this invention is to accurately control an exhaust air-fuel ratio, even when a WGV (waste gate valve) is operating. An ECU is equipped with a turbine passing path constant At that corresponds to a time required for exhaust gas to flow to an air-fuel ratio sensor via a turbine of a turbosupercharger , and a bypass path constant Ab that corresponds to a time required for exhaust gas to flow to the air-fuel ratio sensor via a bypass passage . The ECU calculates first and second fuel injection correction amounts Δt and Δb in which the path constants At and Ab are reflected, respectively. When executing air-fuel ratio feedback control, the ECU 60 selects one of the fuel injection correction amounts Δt and Δb based on at least an open or closed state of the WGV , and corrects a fuel injection amount using the selected fuel injection correction amount. It is thus possible to appropriately compensate for differences in exhaust path lengths and air-fuel ratio fluctuations that arise due to opening or closing of the WGV 1.
