Is Engine Lubricating Oil the Same as Motor Oil?

What does PQ mean in vehicle safety inspection?

PQ in oil testing refers to the amount of ferromagnetic particles contained in the oil, and the PQ value is also known as the mechanical wear index. The following is an introduction to PQ-related information: Instruments for measuring PQ values: There are specialized measuring instruments for PQ values, called PQ meters, also known as "ferrographs". Working principle of PQ: The working principle is that the tested oil sample is slowly and steadily transported by a double-tube infusion pump along the oil delivery pipe to the tray bracket above the magnet pole. The ferromagnetic wear particles in the oil are adsorbed on the center of the tray bracket surface under the action of a strong magnetic field. Meanwhile, the oil flowing through the strong magnetic field area is sucked back by the double-tube infusion pump along the oil return pipe, and then the inner wall of the oil delivery pipe and the center of the tray bracket surface are cleaned with a cleaning solution (such as tetrachloroethylene) that has strong solubility and good volatility.

Which Geely model is indicated by 'geely' on the rear of the car?

The 'geely' on the rear of the car is the English name of the Geely automobile brand, not the car model. Taking the Geely Vision X6 as an example, the following is a detailed introduction to the Geely Vision X6: Introduction to the Vision X6: The length, width, and height are 4500mm, 1834mm, and 1707mm, respectively, with a wheelbase of 2661mm. The Vision X6 has added LED daytime running lights and a 360-degree panoramic imaging system, while also being equipped with larger-sized wheels and a new taillight design. Vision X6 powertrain: It is powered by two engines, a 1.3T and a 1.8L, with the 1.3T model having a maximum output of 133 horsepower. In terms of transmission, the 1.3T engine is paired with a CVT transmission, while the 1.8L engine is matched with a 5-speed manual transmission.

What Causes the Abnormal Noise When Accelerating Uphill?

The abnormal noise when accelerating uphill is caused by carbon deposits on the throttle valve. The main locations of carbon deposits and cleaning methods are as follows: Main Locations of Carbon Deposits: Combustion chamber, intake valve and its surroundings, three-way catalytic converter, lubrication system, etc. The throttle valve is a device located near the top of the combustion system that controls the intake air volume. Due to the working environment and nature of the throttle valve, carbon deposits can form on this component. Carbon Deposit Cleaning Methods: A common method for cleaning carbon deposits on the throttle valve is to remove the throttle valve, clean both sides with carburetor cleaner, and then wipe off the decomposed carbon deposits with a cloth.

Is it necessary to clean car carbon deposits?

It is necessary to clean vehicle carbon deposits, and the air filter should be cleaned frequently. Regularly cleaning the air filter can also help reduce carbon deposits. Driving on the highway can wash away carbon deposits: driving at high speeds can indeed use the airflow to flush the air passages and remove some carbon deposits. Once carbon deposits accumulate, symptoms such as engine shaking and reduced power may occur. Since there is currently no complete way to prevent carbon deposits, if they are not cleaned regularly, carbon deposits will continue to accumulate indefinitely. Reasons for cleaning vehicle carbon deposits: The engine is the core of a car, just like the heart of a person. If a car engine fails to start, it cannot function and becomes a burden, which is wasteful. There are many factors that affect the engine, and carbon deposits are one of them. Carbon deposits have poor thermal conductivity, which reduces the heat transfer coefficient on the surface of components, hinders heat dissipation, and causes the combustion chamber temperature to rise. The increase in carbon deposits leads to overheating of the engine combustion chamber, increasing the amount of nitrogen oxides in car exhaust emissions and worsening the atmospheric environment.

How Long Should Tires Last Before Replacement?

Tires will age after leaving the factory, regardless of how frequently they are used. The typical lifespan of a tire is 4-5 years. Below are methods to determine when tires need replacement: Tires require periodic replacement: If they exceed 5 years, replacement is necessary even if wear is minimal. Therefore, the production date is a reliable indicator for determining when car tires should be replaced. Methods to determine if tires need replacement: If numerous fine cracks appear on the tire surface—these usually develop after about three years of use—regular inspections should be conducted to monitor crack progression. If cracks become excessively long, deep, or appear on the tire sidewall, the tire should be replaced. Additionally, check the tire wear indicators: every tire has wear markers, with passenger car tires typically having a wear indicator height of 1.6 mm and load-bearing tires at 2.4 mm. If the wear indicators are flush with the tread, the tire has worn significantly and should be replaced.

Can alcohol be used for disinfection in cars?

Yes, but be careful not to smoke in the car after disinfection with alcohol. The alcohol concentration should be 75% when using it for disinfection. Here is some extended information: Definition of alcohol: Ethanol (structural formula CH3CH2OH or C2H5OH), commonly known as alcohol, is the most common monohydric alcohol. At room temperature and pressure, it is a flammable, volatile, colorless, transparent liquid with low toxicity. The pure liquid is not directly drinkable and has a special aroma (slightly irritating) and a slightly sweet taste (accompanied by a spicy, irritating flavor). It is flammable, and its vapor can form explosive mixtures with air. It can mix with water in any ratio and is also miscible with chloroform, ether, methanol, acetone, and most other organic solvents. It is an isomer of dimethyl ether. Principle of alcohol disinfection: Alcohol is an organic compound. Its molecules have strong permeability, allowing them to penetrate the membrane on the surface of bacteria and enter their interior. This alters the molecular structure of the proteins that form the basis of bacterial life, causing protein denaturation (protein coagulation), thereby achieving a bactericidal effect.
