AI Technical Summary

⚠Technical Problem

Existing intake technology cannot achieve coordinated optimization of tumble flow and flow rate under different engine operating conditions, resulting in increased intake resistance and reduced flow rate at low loads, and weakened airflow guidance effect at high loads. It cannot adapt to the needs of the engine under all operating conditions, and variable intake systems suffer from wear, jamming, and insufficient control precision.

⚗Method used

An adaptive intake control method combining a flexible deformable wall and a distributed drive unit is adopted. By collecting engine operating parameters in real time, a micro electromagnetic coil array is used to drive the flexible deformable wall to generate continuous stepless deformation along the radial direction of the intake. Combined with a self-learning closed-loop algorithm and a transient correction algorithm, the tumble flow and flow rate are accurately matched.

🎯Benefits of technology

It balances tumble flow and flow rate under all operating conditions, improves combustion completeness and power output smoothness, reduces fuel consumption and emissions, enhances reliability and lifespan, reduces manufacturing costs, adapts to high and low temperature and high boost conditions, and supports remote upgrades and optimizations.

Abstract

The application discloses a working condition self-adaptive deformation intake passage control method, relates to the field of vehicle air passage control, and comprises the following steps: S1, collecting real-time working condition parameters of an engine; S2, determining the running working condition of the current engine according to the working condition parameters; S3, determining a target deformation variable of a flexible deformation wall surface according to the current running working condition; S4, the flexible deformation wall surface is a deformable wall surface covering a throat area of a rigid air passage base body, and is used for generating convex and concave deformation along the air passage radial direction to adjust the profile of an air inlet passage; S5, controlling a distributed driving unit to drive the flexible deformation wall surface to adjust to the target deformation variable; and S6, adjusting the deformation variable in real time according to the running feedback parameters of the engine. Through the above scheme, the rolling flow and flow can be considered in all working conditions, fuel consumption is saved at low speed, emission is clean, power is sufficient at high speed, combustion is sufficient, and the original trade-off is eliminated, and the inherent contradiction is completely solved.
