Embodiment Construction

[0026] The following description relates to apparatus and methods for storing water and delivering it to an intake manifold of an internal combustion engine. In this context, the term "water" is to be understood as also referring to mixtures of water and other substances, such as methanol or ethanol, suitable to favorably influence combustion in an internal combustion engine or to have other desired properties. Furthermore, the words "intake manifold", "intake manifold", "intake manifold" and "inlet area" are used synonymously in the following text. as in figure 1 with 2 As shown in , the apparatus may include a first water container, a water inlet for inputting water into the intake manifold, and a throttle valve arranged between the intake manifold inlet and the internal combustion engine. The first water container is arranged at a higher point than the water inlet, and the water inlet opens into the intake manifold downstream of the throttle valve. A lower region of the ...

Abstract

Methods and systems are provided for introducing water into an intake manifold of an internal combustion engine. In one example, the system may include a water container, a water inlet for inputting water into the intake manifold, and a throttle valve that is arranged between an intake manifold inlet and the internal combustion engine, with the water container arranged at a higher point than the water inlet and the water inlet opening into the intake manifold downstream of the throttle valve. A switchable valve is arranged in fluidic connection with both the water container and the water inlet, with the result that it can enable or interrupt the introduction of water into the intake manifold and also create a Venturi effect at the water inlet, which draws water from the water container.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to German Patent Application No. 102016201276.2 filed on January 28, 2016 and German Patent Application No. 102016201277.0 filed on January 28, 2016. The entirety of the above-mentioned application is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present invention generally relates to methods and systems for making usable water and introducing water into the intake manifold of an internal combustion engine. Background technique [0004] The operation of the internal combustion engine can be optimized by the metered introduction of water into the air / fuel mixture to be combusted. This has basically been known for decades, and corresponding exemplary embodiments can be found, inter alia, in aircraft of the Second World War or in Oldsmobile passenger cars of the early 60's. In the current era, economic experiments have confirmed that wate...
