Abstract
Official abstract text for this publication.
A supercharged internal combustion engine includes an intake tract and a throttle element. Between the compressor and the throttle element, the intake tract is gas-conductively connected on the low-pressure side to a first line and on the high-pressure side to a second line via an overrun air recirculation valve. A fuel tank having an activated carbon filter is provided for supplying fuel to the internal combustion engine, the fuel tank being gas-conductively connected via a valve to a tank venting valve. Between the compressor and the throttle element, the intake tract is gas-conductively connected on the low-pressure side to a third line and on the high-pressure side to a fourth line via the tank venting valve. The overrun air recirculation valve and the tank venting valve are arranged in parallel in terms of flow and the first and third lines and the second and fourth lines are, at least in sections, the same lines.
First claim
Opening claim text (preview).
What is claimed is: 1. A supercharged internal combustion engine comprising: an intake tract in which a compressor is arranged; and a throttle element that is arranged in the intake tract between the compressor and the internal combustion engine, wherein between the compressor and the throttle element, the intake tract is gas-conductively connected on the low-pressure side to a first line and on the high-pressure side to a second line via an overrun air recirculation valve, a fuel tank having an activated carbon filter is provided for supplying fuel to the internal combustion engine, the fuel tank being gas-conductively connected via a valve to a tank venting valve, between the compressor and the throttle element, the intake tract is gas-conductively connected on the low-pressure side to a third line and on the high-pressure side to a fourth line via the tank venting valve, and the overrun air recirculation valve and the tank venting valve are arranged in parallel in terms of flow and the first and third lines and the second and fourth lines are, at least in sections, the same lines, wherein the throttle element is disposed in the fourth line. 2. The supercharged internal combustion engine as claimed in claim 1 , wherein the overrun air recirculation valve and the tank venting valve are arranged in a common housing, and the tank venting valve comprises a Venturi nozzle and a flow widening valve. 3. The supercharged internal combustion engine as claimed in claim 2 , wherein the activated carbon filter is gas-conductively connected to the intake tract via the valve. 4. The supercharged internal combustion engine as claimed in claim 3 , wherein a first throttle element, via which the tank venting valve is shut off, is provided in the first or second line. 5. The supercharged internal combustion engine as claimed in claim 1 , wherein the tank venting valve comprises a Venturi nozzle and a flow widening valve.
