What does the API of engine oil represent?

The API grade of engine oil refers to the quality standard specified for engine oil. Below is relevant information: 1. The first letter of the specification for engine oil used in gasoline engines is "S", with a total of 12 grades from SA to SN. The first letter of the specification for engine oil used in diesel engines is "C". If the engine oil label is "SC", it indicates that the oil is universal, meaning it can be used in both gasoline and diesel engines. 2. Taking gasoline engines as an example, the engine oil grades used in gasoline engines, from low to high, are SE, SF, SG, SH, SJ, SL, SM, and SN. As of August 2019, most of the engine oils used in cars in China were SJ, SL, SM, and SN.

What Are the Reasons for a Car Consuming Too Much Fuel?

There are three main reasons why a car consumes too much fuel: 1. Personal factors, the driver's lack of skill: Improper gear shifting and excessive braking during driving artificially increase engine power loss. Additionally, excessive braking leads to more frequent starts, and starting consumes higher fuel rates; 2. The engine's condition is directly related to fuel consumption: If the engine has issues, fuel consumption will significantly increase. High idle speed adjustment, partial short circuits in the high-voltage coil, burnt distributor contacts, or capacitor breakdown can result in weak high-voltage sparks, reduced ignition capability, and incomplete combustion of some fuel mixtures, all of which increase fuel consumption; 3. Neglecting maintenance during car use: Not using fuel additives regularly.

What Causes the Engine to Make a Buzzing Sound?

Reasons for engine buzzing sound: 1. Buzzing sound at idle: This may be caused by the operation of the electronic fan used for radiator cooling. However, this sound is intermittent. If the buzzing persists, it could indicate a faulty temperature sensor or temperature regulator. 2. Buzzing sound during low-speed driving or gear shifting: This is usually caused by excessive clearance between the piston and cylinder wall. Improper installation leading to overly tight assembly or abnormal wear can also produce buzzing sounds. 3. Buzzing sound during high-speed driving: This may be caused by sound resonance. During high-speed operation, using incorrect engine oil can also lead to this phenomenon. Improper oil selection prevents adequate lubrication inside the engine, potentially causing buzzing sounds. Alternatively, water pump abnormalities such as blockages or leaks can also result in engine buzzing issues.

How to use the cruise control on the Verano?

The usage method of the cruise control on the Verano is as follows: 1. When the vehicle speed reaches above 40 km/h, press the cruise control button. 2. Press the set button to set the speed. 3. Press the set button again to activate the cruise function. Notes for using cruise control on the Buick Verano: 1. Pressing the brake will deactivate the cruise control. The speed value will not be cleared, and you can resume the previously set speed to continue cruising. 2. In complex road conditions or under adverse weather conditions, using cruise control may be dangerous. Please turn off cruise control and drive manually. 3. On downhill sections, the vehicle may accelerate quickly. You should use the brake to control the speed to prevent accidents caused by loss of control.

Working Principle of Disc Brakes?

During braking, hydraulic fluid is forced into the inner and outer wheel cylinders, causing the pistons to press the brake pads against the brake disc under hydraulic pressure, generating friction torque to achieve braking. This is the working principle of disc brakes. Disc brakes mainly come in two types: full disc and spot disc. In full disc brakes, both the stationary and rotating elements of the friction pair are disc-shaped, referred to as the stationary disc and rotating disc respectively. The entire working surface of the brake disc can simultaneously contact the friction pads. Spot disc brakes have their brake pads and actuation devices mounted in a caliper-shaped bracket that spans both sides of the brake disc, known as the brake caliper. Caliper disc brakes have strong heat dissipation capabilities and good thermal stability. Disc brakes are now widely used in passenger cars. Most cars use them on all wheels, while a few only use them as front wheel brakes, paired with drum brakes on the rear wheels.
