Solution Overview
Problem
Existing water tank devices for internal combustion engines with water injection systems require additional space due to their complex configurations, which increases installation space requirements in vehicles.
Innovation Solution
A compact water tank device with an integrated filter system that allows for efficient heat exchange with a water tank, using a filter device with a heat transfer surface to stabilize the activated carbon filter and reduce emissions, while maintaining a compact design by arranging the filter device either partially or completely inside the water tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a water injection system is added to an internal combustion engine, then power output increases and consumption decreases, but installation space requirement increases
Solution Approach 1:
The filter device is integrated into the water tank structure, with the filter housing forming part of the water tank wall. This merging of the filter device with the water tank eliminates the need for separate filter housing space, thereby reducing overall installation space while maintaining water injection functionality
Solution Approach 2:
The water tank serves multiple functions: it stores water for injection and simultaneously houses the filter device for purifying fuel vapors. This multi-functionality reduces the need for separate components and space, addressing the installation space constraint
2Object-generated harmful factors
If a filter device is added to purify fuel vapor, then emissions decrease, but device complexity increases
Solution Approach 1:
The filter device is combined with the water tank structure, where the filter housing forms part of the tank wall. This integration simplifies the overall device structure by eliminating separate filter housing components, thereby reducing device complexity while maintaining emission reduction functionality
Solution Approach 2:
The filter element is nested within the filter housing that is itself integrated into the water tank structure. This nested arrangement allows the filter device to be compact and structurally simplified, reducing overall device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves a compact design with improved filter effectiveness and reduced emissions by enabling efficient heat transfer between the filter device and the water tank, stabilizing the filter and minimizing environmental pollution.
Implementation Method 1
an exchange of heat with the water which can be stored in the water tank is made possible via the heat transfer surface
Implementation Method 2
The filter device is set up, in particular, for purifying fuel vapor or fuel gases from a fuel tank of the internal combustion engine

AI summary
A water tank device for an internal combustion engine with water injection, includes a water tank with an internal volume, which is at least partly delimited by a tank wall and in which a liquid is stored for the water injection in the internal combustion engine, and a filter device, which is designed to clean fuel vapor from a fuel tank of the internal combustion engine. The filter device has a heat transfer surface. The filter device is closed so as to be fluid-tight against the liquid which can be received in the internal volume. The filter device is arranged on the water tank such that a heat exchange with the liquid which can be stored in the water tank is facilitated via the heat transfer surface.
