Abstract
Official abstract text for this publication.
A system for controlling condensation of water within an intake manifold of an engine is disclosed. The system may have a humidity sensor. The humidity sensor may be configured to generate a signal indicative of a humidity of intake air. The system may also have a controller communicably coupled to the humidity sensor. The controller may be configured to receive the signal indicative of the humidity of the intake air. The controller may be also configured to control an operational parameter of at least one of the engine and an engine component to maintain the humidity of the intake air within the intake manifold below a predetermined threshold.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for controlling condensation of water within an intake manifold of an engine, the system comprising: a humidity sensor configured to generate a signal indicative of a humidity of the intake air in the intake manifold; a temperature sensor configured to generate a signal indicative of the temperature of the intake air in the intake manifold; and a controller communicably coupled to the humidity sensor, the temperature sensor, the engine, and an aftercooler associated with the engine, the controller configured to: receive the signal indicative of the humidity of the intake air; receive the signal indicative of the temperature of the intake air; determine a pressure of the intake air within the intake manifold; compare the humidity, the temperature, and the pressure of the intake air with a pre-calibrated data set to obtain a predetermined threshold; and control an operational parameter of at least one of the engine and the aftercooler to maintain the humidity of the intake air within the intake manifold below the predetermined threshold. 2. The system of claim 1 , further comprising: a pressure sensor configured to generate a signal indicative of the pressure of the intake air within the intake manifold. 3. The system of claim 1 , wherein the controller is further configured to: receive a signal indicative of a load on the engine for determining the pressure of the intake air within the intake manifold.
