AI Technical Summary

Problems solved by technology

If the engine speed drops, this leads to a lower exhaust gas mass flow and thus to a lower turbine pressure ratio or lower turbine power
Therefore, towards lower engine speeds, the boost pressure ratio also decreases

Embodiment Construction

[0041] The following description relates to systems and methods for flap valves. The flap valve may be a substantially planar valve configured to regulate gas flow through the intake passage to the engine. Such as Figure 1A As shown, the flap valve can be adjusted to a first position, a second position, and one or more positions therebetween. In one example, the first position corresponds to a fully open position of the valve where intake air can freely flow to the engine. The second position corresponds to a fully closed position of the valve in which intake air flow to the engine is substantially zero.

[0042] The flap valve also includes an insulating portion coupled to the actuator of the flap valve such that the insulating portion can pivot and / or rotate with the flap valve. The insulating portion may be configured to thermally isolate the flap valve. For example, an insulating portion may be arranged between the flap valve and an outlet of low pressure exhaust gas r...

Abstract

The invention relates to a supercharged internal combustion engine with a compressor, an exhaust-gas recirculation arrangement and a flap. Methods and systems are provided for an at least partially insulated throttle valve. In one example, a system may include a throttle valve having a first side configured to contact intake air flow and a second side configured to contact exhaust gas recirculation flow, where at least a portion of the second side comprises thermally insulating materials.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to German Patent Application No. 102016215865.1 filed on 24.08.2016. The entire contents of the above-cited patent applications are hereby incorporated by reference in their entirety for all purposes. technical field [0003] The present description generally relates to an integrated valve for a motor vehicle comprising an internal combustion engine and a motor vehicle having such an integrated valve. Background technique [0004] Internal combustion engines of the type mentioned in the introduction are used as motor vehicle drive units. In the context of the present disclosure, the expression "internal combustion engine" covers diesel engines and Otto cycle engines and also hybrid internal combustion engines utilizing a hybrid combustion process and hybrid drives comprising not only the internal combustion engine but also electric machines , the electric machine can be connected in d...
