The advantage of installing an oil catch can on the engine is that it can reduce the trouble caused by carbon deposits to the car, while the disadvantage is that the oil catch can needs to be cleaned regularly. The function and working principle of the oil catch can are as follows: Function of the oil catch can: The oil catch can uses the negative pressure in the intake manifold to draw blow-by gases formed in the crankcase and direct them back into the combustion chamber for re-burning. These blow-by gases mainly consist of oil vapor and combustible mixed gas. Since oil is viscous, if it directly enters the intake pipes, it may adhere to the walls of the intake pipes, forming carbon deposits that obstruct airflow. Working principle of the oil catch can: The oil catch can can lower engine temperature and increase cylinder durability. Its working principle involves collecting oil vapor, preventing the vapor from undergoing secondary combustion, and reducing the formation of carbon deposits. It primarily serves to protect the engine and can effectively alleviate the issue of oil burning.

Why doesn't the newly added windshield washer fluid come out?

Just added windshield washer fluid not coming out is due to internal blockage, which requires timely cleaning or replacement of the delivery hose. Below are specific details about the windshield washer fluid: 1. Pay attention to temperature: Before adding windshield washer fluid, it's necessary to understand the local climate, mainly the temperature. If it's below zero degrees, choose a windshield washer fluid with a low freezing point to ensure it doesn't freeze in the car after being added. 2. Water cannot replace windshield washer fluid: Water should not be used as a substitute for windshield washer fluid in cars, mainly because it freezes at 0 degrees in winter, and tap water contains many impurities, which can easily cause aging of components.

Air conditioning zoning: Air conditioning zoning is the reasonable division of the entire air conditioning area into several temperature control zones based on load analysis and the differences in air conditioning loads. The purpose of air conditioning zoning is to enable the air conditioning system to effectively track load changes, improve the indoor thermal environment, and reduce air conditioning energy consumption. 2. Ventilation system: Its function is to ensure indoor ventilation while the car is moving, meaning that fresh air is continuously introduced into the car interior to expel dust, carbon dioxide, and harmful gases from the engine.

What Causes Engine Chain Noise?

Engine chain noise is caused by delayed oil changes, damaged oil pumps, lack of tension in the tensioning device, etc. Delayed oil changes: Failure to change engine oil promptly leads to noise. The chain requires oil lubrication, and delayed oil changes will cause chain noise. Replace the oil to resolve the issue. Damaged oil pump: Check for oil pump damage, which can result in insufficient oil supply, preventing timely lubrication of the timing chain and causing noise. Replace or repair the oil pump. Lack of tension in the tensioning device: This can be due to insufficient tension in the chain tensioning device, stretched timing chain, abnormal wear of the guide chain plate, or damaged timing sprockets. Replace the specific mechanical component that is damaged.
