What is the 'set' in a car?

Why Shouldn't You Lend Your Car to Others?

The reasons for not lending your car include legal regulations, high accident risks, and borrowers' lack of care for the vehicle. Legal regulations: According to relevant laws, if the borrower causes an accident, insurance coverage is often insufficient, and the car owner may still bear responsibility. If the borrower is unreasonable, there may be no compensation for damages. High accident risks: The rapid increase in vehicles has made road conditions more tense and congested, making scratches, collisions, and undercarriage damage more likely. Borrowers' lack of care for the vehicle: Few people who borrow cars take good care of them, often leading to high-speed driving and overloading.

Will Replacing Car Headlights Cause Depreciation?

There will be some impact. Whether the vehicle's headlights are replaced due to collision in a traffic accident or natural cracking, any replacement will have an effect. What are the most common causes of headlight failures: Condensation inside the vehicle's headlights is the most frequently occurring issue. As long as the vehicle is within the normal warranty period and the headlights have not been modified privately, you can directly apply for headlight replacement at the brand's after-sales service department. If the issue is caused by unauthorized modifications, it will not be covered under the normal warranty. How can vehicle headlights be modified: Firstly, you can replace the headlight bulb light source. If the original vehicle uses halogen bulbs, they can be replaced with LED bulbs or xenon bulbs. If the original vehicle's summer performance is poor, you can switch to LED bulbs or directly upgrade to laser headlights. However, internal modifications to the headlights are relatively complex and require the addition of lenses during the modification process.

What are the eight classifications of engines?

Engines can be classified into eight types: gasoline engines, diesel engines, gas engines, steam engines, steam turbines, hot air engines, gas turbines, and jet engines. Engine classification methods: Classification based on different piston movement methods, classification according to the type of fuel used, classification by cooling method, classification by the number of piston strokes during a working cycle, classification by the number of cylinders, classification by cylinder arrangement, and classification by intake state. Brief description of classifications: In general, most engines used in automobiles are distinguished by the type of fuel used, such as gasoline engines, diesel engines, gas engines, steam engines, etc. They can also be classified by the number of cylinders, which includes single-cylinder and multi-cylinder engines. Single-cylinder and twin-cylinder engines are mainly used in motorcycles and agricultural machinery, while automobiles typically use multi-cylinder engines, such as three-cylinder, four-cylinder, five-cylinder, six-cylinder, eight-cylinder, ten-cylinder, and twelve-cylinder engines. Currently, three-cylinder engines are very popular and are mostly used in small-displacement passenger cars. Five-cylinder and ten-cylinder engines are relatively rare. Examples of vehicles using five-cylinder engines include the Audi 100, Audi RS3, Audi TTRS, and Volvo T5. Ten-cylinder engines are usually designed in a V-configuration and were used in early F1 racing cars, as well as in the T815 ten-cylinder air-cooled engine.

Why Reset the Transmission?

Resetting the transmission means clearing the learned values, which is essentially initialization. This can eliminate bad usage habits of the transmission and extend its service life. Automatic Transmission: It is a type of transmission that can automatically shift gears based on the vehicle's speed and engine RPM, as opposed to a manual transmission. Four Common Types of Automatic Transmission: There are four common types of automatic transmissions in vehicles: Hydraulic Automatic Transmission (AT), Continuously Variable Transmission (CVT), Automated Manual Transmission (AMT), and Dual-Clutch Transmission.

What is an Engine Stroke?

An engine stroke refers to an engine that completes one working cycle in two strokes. In a two-stroke engine, the crankshaft rotates once, and the engine performs work once. First stroke: The piston moves from top dead center to bottom dead center, completing two actions. The spark plug ignites, performing work—exhaust, closing the intake, and compressing the air-fuel mixture from the lower part of the piston into the crankcase, then entering the cylinder again from the upper part of the piston. Second stroke: The piston moves from bottom dead center to top dead center, completing two actions. All intake and exhaust ports are closed, compressing the air-fuel mixture. Completing one working cycle requires the piston to move through two strokes, hence the name two-stroke.

Why Does the Car Shake When the Air Conditioner is Turned On?

Car shaking is caused by carbon deposits on the spark plugs, carbon buildup on the intake valves, or the use of inappropriate fuel. Carbon deposits on the spark plugs: After a period of use, spark plugs can accumulate carbon deposits. If not cleaned in time, this can reduce the engine's torque output, causing the car to shake when the air conditioner is turned on. To clean the spark plugs, soak them in a container filled with white vinegar for 2-3 hours (or 4-5 hours for severe cases), then scrub them with a stiff brush to remove the carbon deposits. Afterward, clean them with gasoline and let them air dry naturally. Carbon buildup on the intake valves: Older cars typically have a normal cylinder pressure of around 10.5, while newer cars have pressures of 11 or higher. If the cylinder pressure is abnormal, the car's computer may detect cylinder misfires and automatically cut off fuel supply, leading to shaking when starting the car until it fails to start. Abnormal cylinder pressure can be resolved by cleaning the carbon buildup on the intake valves. This can be done by driving at high speeds (above 4,000 RPM) to burn off the carbon deposits in the cylinders. Cleaning the intake valves requires removing the intake manifold and manually scrubbing or using cleaning agents to remove the buildup. Use of inappropriate fuel: The fuel octane rating represents the fuel's resistance to knocking. Higher-octane fuel can extend the lifespan of the catalytic converter and reduce emissions. Additionally, engines with different compression ratios require different fuel qualities. Using the wrong gasoline can lead to severe carbon buildup in the engine, causing the car to shake when the air conditioner is turned on. Generally, engines with a compression ratio below 7.5 can use 90-octane gasoline, those between 7.5 and 8.0 should use 90 or 93-octane, those between 8.0 and 10.0 should use 93 or 95-octane, and those above 10.0 should use 97-octane gasoline.
