Abstract:
A system for providing a catalyst to a first flow of gas. The first flow of gas has an operating pressure. A pipe carries the first flow of gas from a compressor of a turbocharger to a combustion chamber. The operating pressure of the first flow of gas varies in accordance with an operation of the compressor. The system includes an enclosure, a pump, and an atomizer. The enclosure receives a portion of the first flow of gas at the operating pressure. The pump is positioned in the enclosure. The pump receives from within the enclosure the portion of the first flow of gas. The pump provides the portion of the first flow of gas at a second pressure. Any gas that exits the enclosure is provided by the pump at the second pressure. The atomizer receives a solution having the catalyst and provides a vapor having the catalyst. The portion of the first flow of gas at the second pressure carries the vapor out of the system and into the first flow of gas for delivery to the combustion chamber. A magnitude of the second pressure comprises a magnitude of the operating pressure plus a magnitude of a pressure increase provided by the pump.
Abstract:
An air induction system (10) with active noise control includes a self-cleaning air filter (68) that is integrated within an air intake housing (12). The self-cleaning air filter filters out contaminants such as dust and dirt particulates from air flowing through the intake housing. The self-cleaning filter is powered and controlled by the same electronic unit (38) that is used to power the active noise control system.
Abstract:
A control device for an internal combustion engine includes a compressor, a cooling water circuit, an intercooler, an EGR device and an ECU. The ECU is configured to: (a) control the temperature of the cooling water of the intercooler to a target temperature in a specified external air state in which an external air temperature and an external air humidity are a specified temperature and a specified humidity, the target temperature being the temperature of the cooling water of the intercooler required for ensuring a specified performance in the specified external air state; and (b) control the EGR device based on an EGR rate mapping of the EGR rate. The EGR rate mapping set the EGR rate so that the dew point of cooler inflow gas -flowing into the intercooler does not exceed the target temperature.
Abstract:
Es wird eine Sensoranordnung (10) zur Bestimmung eines Feuchtegehalts eines in einer Hauptströmungsrichtung (12) strömenden fluiden Mediums, insbesondere einer Ansaugluft einer Brennkraftmaschine, vorgeschlagen. Die Sensoranordnung (10) weist ein Sensorgehäuse (14), insbesondere einen in ein Strömungsrohr eingebrachten oder einbringbaren Steckfühler, mindestens einen in dem Sensorgehäuse (14) angeordneten Feuchtesensor (24) zur Bestimmung des Feuchtegehalts des fluiden Mediums und mindestens ein Rückhalteelement (28) auf. Das Rückhalteelement (28) ist für Feuchtigkeit zumindest teilweise durchlässig. Die Sensoranordnung (10) weist eine Einlassöffnung (16) für Feuchtigkeit in das Sensorgehäuse (14) auf und der Feuchtesensor (24) und das Rückhalteelement (28) sind so in dem Sensorgehäuse (14) angeordnet, dass der Feuchtesensor (24) über die Einlassöffnung (18) und das Rückhalteelement (28) mit Feuchtigkeit beaufschlagbar ist. Die Sensoranordnung (10) weist mindestens eine von der Einlassöffnung (16) getrennt angeordnete Auslassöffnung (18) für Feuchtigkeit aus dem Sensorgehäuse (14) in das strömende fluide Medium auf.
Abstract:
A method and device for controlling emissions of VOC's comprises transporting VOC's to an engine and transporting the exhaust from the engine into a manifold. Supplemental air is transported into the manifold and heat is transferred from the exhaust to the supplemental air within the manifold. The supplemental air is mixed with the exhaust and the mixture is transferred to a pollution abatement device.
