Integrated Intake Line Connecting Member for Engine Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing internal combustion engine intake lines occupy significant space, imposing design constraints and limiting the use of this space for other vehicle components or extensions.
Innovation Solution
The engine features a compact connecting member that integrates the functions of multiple components typically found in the intake line, including a flexible sleeve, resonator, and lubricating oil vapour recirculation system, thereby reducing the overall footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components (flexible sleeve, resonator, lubricating oil vapour recirculation line) are used in the intake line, then each component can perform its specific function, but the overall space occupied by the intake line increases significantly
Solution Approach 1:
The patent combines the flexible sleeve, resonator, and lubricating oil vapour recirculation line into a single integrated connecting member. The resonator is positioned within the flexible sleeve, and the lubricating oil vapour recirculation line is integrated into the same structure, allowing all three components to perform their functions while occupying significantly less space than separate components would require.
Solution Approach 2:
The connecting member is designed as a multi-functional component that simultaneously serves as a flexible connection element, acoustic resonator, and lubricating oil vapour recirculation pathway. This universal design allows a single component to replace what would traditionally require multiple separate parts, directly reducing the intake line's overall footprint.
2Stress or pressure
If the intake line includes a compressor for compressing air, then air pressure in the intake manifold increases, but the space required for the compressor and associated components increases
Solution Approach 1:
The compressor is integrated directly into the connecting member that houses the resonator and lubricating oil vapour recirculation line. This consolidation allows the compressor to be positioned within the existing intake line structure rather than requiring separate space, thereby maintaining the air compression function while minimizing the overall volume occupied by these components.
3Adaptability or versatility
If the flexible sleeve is made highly flexible to compensate for engine movement, then the connection between engine and air filter is maintained, but the structural complexity and space requirements increase
Solution Approach 1:
The flexible sleeve is combined with the resonator and lubricating oil vapour recirculation line in a single integrated connecting member. This integration allows the flexible sleeve to perform its movement compensation function while simultaneously housing the other components, thereby maintaining adaptability to engine movement without requiring additional separate structures that would increase overall complexity and space requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively reduces the spatial requirements of the intake line, allowing for more flexible vehicle design and potentially enabling the inclusion of additional components or chassis extensions.
Implementation Method 1
The resonator 105 is a known instrument whose function is to reduce the noise produced by air passing through the intake line and subjected to compression
Implementation Method 2
The intercooler 104 is a heat exchanger configured to cool the compressed air from the turbocharger compressor
Implementation Method 3
The compressor is used to compress the air drawn through the air intake, so that the intake manifold receives air with a greater pressure than ambient pressure
Implementation Method 4
the sleeve 102 is flexible precisely to compensate for the relative movement of the engine 100 with respect to the chassis

AI summary
An internal combustion engine for a motor vehicle is disclosed. The engine includes a crankcase, an intake manifold, and an intake line extending from an air intake to draw outside air to the intake manifold, the intake line comprising a connecting member arranged between the air intake and the intake manifold and comprising in turn a flexible sleeve extending along a longitudinal axis, an intake resonator attached to the flexible sleeve and extending axially along the longitudinal axis at least partially within the flexible sleeve, and a nozzle on a radially outer surface of the flexible sleeve to define an inlet orifice in the flexible sleeve.
