AI Technical Summary

Technical Problem

When a vehicle brakes suddenly, the engine oil shifts significantly within the oil pan, causing the oil suction plate to lack oil and resulting in cavitation, which can affect the normal operation of the engine and potentially cause damage.

Method used

Design an engine oil pan that includes a front spoiler and a rear spoiler. The front and rear spoilers are horizontally fixed inside the oil pan with gaps to accommodate the oil suction components and prevent large-scale movement of engine oil during emergency braking, ensuring that the oil suction plate has a sufficient oil supply.

Benefits of technology

It effectively prevents the large-scale movement of engine oil during emergency braking, ensures sufficient oil supply to the oil suction plate, improves the stability and reliability of the lubrication system, reduces component wear, extends engine life, and reduces manufacturing costs.

Abstract

本实用新型公开了一种发动机油底壳，属于油底壳领域，包括油底壳、前扰流板、后扰流板以及吸油件，前扰流板与后扰流板均水平固定于油底壳内部，且前扰流板与后扰流板位于同一水平面上，前扰流板与后扰流板之间留有空隙，吸油件从空隙延伸至油底壳的内底壁特点。通过增设前后扰流板，有效阻止了机油在急刹车或剧烈加速时因惯性作用产生的过大流动，确保吸油盘位置始终有足够的机油供应，显著提高了发动机润滑系统的稳定性和可靠性。同时，减少了因吸空现象导致的发动机部件磨损和损坏，延长了发动机的使用寿命。相比其他复杂的解决方案，本提案仅需添加前后扰流板，有效降低了制造成本。
