How to Identify the Grade of Engine Oil?

What is the appropriate tire pressure in summer?

Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can usually be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; It accelerates localized wear of the tread pattern in the center of the tire, reducing tire lifespan; Vehicle vibration increases, indirectly affecting the lifespan of other components; It causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the car while driving; Puncture resistance decreases. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks and blowouts. Hazards of insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; It makes the steering wheel heavy and prone to deviation, which are factors detrimental to driving safety; It increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; It reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, causing damage and abnormal wear at the bead area; The friction between the tire and the ground increases exponentially, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts; It increases tire body deformation, making the tire side prone to cracks and causing flexing movements, leading to excessive heat, accelerating rubber aging, cord fatigue, and breakage, and increasing the tire's contact area with the ground, accelerating shoulder wear.

What Causes Car Shaking During Cold Start?

Car shaking during cold start may indicate the following three conditions: 1. Severe engine carbon deposits. The most common cause of car shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. The lower the temperature, the more fuel is required for a cold start, and the presence of carbon deposits can significantly affect the smoothness of the cold start. 2. Ignition system issues. Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or weak spark plug firing can also lead to such symptoms. 3. Unstable oil pressure. If you have already cleaned the engine carbon deposits, cleaned the throttle body, replaced the oil gasket and spark plugs, but still notice shaking at idle, it is recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor for any abnormalities.

Where is the air conditioning filter of Trumpchi GS7 located?

Trumpchi GS7's air conditioning filter is located inside the glove compartment on the passenger side. Below is relevant information about the air conditioning filter: 1. When driving with the air conditioning on, the car draws in external air into the cabin. However, the air contains various particles. Without the air conditioning filter, these particles can enter the cabin, not only contaminating the car's air conditioning system and reducing the cooling system's performance but also causing allergic reactions, lung damage, irritation from ozone, and unpleasant odors, all of which affect driving safety. Air conditioning filters containing activated carbon can absorb a significant amount of odors. The general replacement cycle for an air conditioning filter is every 10,000 kilometers. 2. A high-quality air filter can absorb fine particles, reduce respiratory discomfort, lessen irritation for allergy sufferers, enhance driving comfort, and protect the air conditioning cooling system.

What Causes Black Exhaust Pipes in Engines?

The reasons for black exhaust pipes and their solutions are as follows: 1. Poor quality of automotive fuel. Poor quality automotive fuel not only leads to incomplete combustion but can also cause carbon deposits to form inside the engine. The optimal air-fuel ratio is 14.7:1, which ensures maximum combustion efficiency and minimizes pollution emissions. Solution: Try to use the same brand of engine oil. 2. Poor driving habits. Carbon buildup in cars is closely related to the driver's poor driving habits. Common behaviors such as idling with the air conditioning on or not warming up the car in winter can result in an improper air-fuel ratio, leading to black exhaust pipes. Solution: Develop good driving habits.

What is the function of the steering transmission mechanism?

The function of the steering transmission mechanism is to connect the transmission output shaft and the main reducer input shaft that are not on the same straight line, and to ensure reliable power transmission even when the angle and distance between the two shafts frequently change. More information about the universal transmission device is as follows: 1. The universal transmission device can be divided into closed and open types. Closed universal transmission device: It uses a single universal joint, and the drive shaft is enclosed in a sleeve. The sleeve is connected to the frame with a ball joint and fixedly connected to the drive axle. Its most notable feature is that the transmission housing acts as a thrust tube to transmit the longitudinal force of the vehicle, thereby allowing the drive shaft housing to function as a longitudinal swing arm in the suspension system and guiding mechanism. This is particularly necessary when the rear suspension uses coil springs as elastic components. 2. The open universal transmission device has a simple structure and is lightweight. Modern vehicles widely use open universal transmission devices, which demonstrate the application of universal transmission devices.

What is the battery model of the Elantra?

The battery model of the Elantra is 55D23L. Below is some relevant information about car batteries: 1. The lifespan of a battery is generally over 2 years. If the battery runs out of power, it is recommended to first measure the battery voltage. If using a multimeter, measure the battery voltage when starting the engine. You can first use a high-frequency discharge meter or a battery tester to measure, ensuring that under a load current of no less than 110 amps, the minimum voltage should not be lower than 9.6 volts and should remain stable within 5 seconds. 2. If the voltage is below 9.6 volts but can remain stable within 5 seconds, it indicates over-discharge and should be recharged promptly. If the voltage is below 9.6 volts and cannot remain stable within 5 seconds, dropping rapidly to 0 volts or close to 0 volts, it suggests that the battery may be faulty and might need replacement.
