Distribution Module for Engine Intake Mixture Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distribution modules for combustion engines are not adaptable to distribute various types of gas mixtures, particularly combinations of cooled and uncooled intake air and recirculation gas, limiting their versatility in different engine operating conditions.
Innovation Solution
A distribution module with multiple inlets for cooled and uncooled intake air and recirculation gas, a mixing chamber, and separate distribution organs with adjustable orifices and channels to ensure uniform and effective mixing and distribution of the intake mixture to multiple cylinders, allowing for flexible operation in different engine modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single inlet design is used for gas mixture distribution, then the device structure is simple, but the adaptability to different gas mixtures is poor
Solution Approach 1:
The distribution module is designed with multiple inlets (first inlet for cooled intake air, second inlet for uncooled intake air, third inlet for recirculation gas) that can handle different gas types. The mixing chamber and distribution organs work together to uniformly distribute various gas mixtures to multiple cylinders, making the device universally applicable to different engine operating conditions and gas composition requirements.
2Manufacturing precision
If separate distribution organs are used for different gases, then the distribution uniformity is improved, but the device complexity increases
Solution Approach 1:
The distribution system is segmented into separate distribution organs: a first distribution organ for cooled intake air, a second distribution organ for uncooled intake air, and a third distribution organ for recirculation gas. Each distribution organ has its own inlet and distribution path leading to the mixing chamber, ensuring that each gas type is distributed uniformly and independently before mixing, thereby achieving precise control over the final gas mixture composition.

Function Achieved in This Case
Enables efficient and uniform distribution of various gas mixtures to combustion engine cylinders, improving engine performance and adaptability across different operating conditions by ensuring effective mixing and metering of intake air and recirculation gas.
Implementation Method 1
a mixing chamber into which lead the first, second and third inlets and in which the intake mixture is made
Implementation Method 2
the second inlet being connected to a first distribution organ arranged to distribute the uncooled intake air in the mixing chamber, the third inlet being connected to a second distribution organ arranged to distribute the recirculation gas in the mixing chamber, the at least one of the first and second distribution organs having a tubular form
