Turbocharger Exhaust Pipe 95-Degree Bend for Sensor Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exhaust systems for turbocharged vehicles face limitations in space utilization and oxygen sensor installation due to the 90° bent exhaust connecting pipe, leading to increased backpressure and degraded sensing performance.
Innovation Solution
A streamlined exhaust connecting pipe bent at 95° or more towards the ground direction, combined with a diagonal catalytic converter arrangement and an improved boss structure for oxygen sensor fastening, allowing for easier sensor insertion and reduced backpressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the exhaust connecting pipe is bent at 90° to minimize exhaust pressure, then exhaust performance is improved, but the catalytic converter volume is restricted and layout space is reduced
Solution Approach 1:
The exhaust connecting pipe is bent at an angle of 95° or more (greater than the conventional 90°) to create additional spatial dimension. This angular adjustment allows the catalytic converter to be positioned diagonally toward the ground, effectively utilizing three-dimensional space and increasing the available volume for the catalytic converter while maintaining acceptable exhaust pressure levels.
2Loss of energy
If the exhaust connecting pipe is bent at 90° to minimize exhaust pressure, then exhaust performance is improved, but the oxygen sensor insertion is difficult and sensing performance is degraded
Solution Approach 1:
By bending the exhaust connecting pipe at 95° or more, the catalytic converter adopts a diagonal arrangement toward the ground. This spatial reconfiguration creates a more accessible orientation for oxygen sensor insertion, allowing the sensor to be inserted straight into the catalytic converter along its longitudinal axis, thereby improving both installation ease and sensing performance.
3Volume of stationary object
If the catalytic converter is arranged diagonally toward the ground, then layout space is increased, but the oxygen sensor fastening length is insufficient
Solution Approach 1:
A boss structure is预先 (pre-established) on the catalytic converter body at the appropriate position and orientation. This pre-configured fastening structure is designed with sufficient length and proper angular orientation to accommodate the diagonal arrangement of the catalytic converter, ensuring that the oxygen sensor can be securely fastened with adequate insertion length while maintaining the space-efficient diagonal configuration.
