The four strokes in a gasoline engine are: 1. Intake stroke; 2. Compression stroke; 3. Power stroke; 4. Exhaust stroke. A gasoline engine is an engine that uses gasoline as fuel to convert internal energy into kinetic energy. Its components include: 1. Engine block, crankshaft connecting rod mechanism, and valve train; 2. Fuel supply system, cooling system, and lubrication system. Gasoline engines are characterized by high speed, simple structure, light weight, low cost, smooth operation, and easy maintenance. Due to the low viscosity and fast evaporation of gasoline, a fuel injection system can be used to inject gasoline into the cylinder. After compression reaches a certain temperature and pressure, a spark plug ignites the mixture, causing the gas to expand and perform work.

What is the function of car shock absorber spring lift spacers?

The function is to prevent the shock absorber from contacting the car body, thereby protecting the shock absorber. Below is an introduction to the purpose of shock absorbers: 1. Function: To accelerate the attenuation of vibrations in the car frame and body, thereby improving the driving smoothness (comfort) of the car, most car suspension systems are equipped with shock absorbers. 2. Composition: The car's shock absorption system consists of both springs and shock absorbers. The shock absorber is not used to support the weight of the car body but to suppress the oscillations when the spring rebounds after absorbing shocks and to absorb the energy from road impacts. The spring serves to cushion impacts, transforming 'a single large energy impact' into 'multiple small energy impacts,' while the shock absorber gradually reduces these 'multiple small energy impacts.' Without a shock absorber, it would be impossible to control the spring's rebound, causing the car to bounce severely on rough roads and lose tire grip and tracking stability during turns due to the spring's oscillations.

Should You Press the Clutch or the Accelerator When Reversing?

It depends on the specific situation: 1. On flat ground: The car does not require much power to reverse, and you can control it by pressing the clutch to engage the semi-engagement point and using the brake. 2. When reversing on a slope: If the clutch alone cannot provide sufficient power, you can lightly press the accelerator to supplement the power. Here are some additional details: 1. The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. 2. During driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and transmission, thereby cutting off or transmitting the power from the engine to the transmission. 3. The clutch is a common component in mechanical transmissions, allowing the drivetrain to be separated or engaged at any time.

What are the precautions for driving through highway toll stations?

Here are the precautions for driving through highway toll stations: 1. Fasten your seat belt when passing through the toll station. 2. Do not change lanes arbitrarily at the toll station entrance. If a vehicle changes lanes while passing through the toll station, it can easily cause an accident. The driver will be held fully responsible for the accident and may also be fined 200 yuan. 3. Do not park randomly at the toll station. 4. Slow down when passing through the ETC lane. The electronic barrier takes some time to react when lifting. If your speed is too fast and you are caught on camera, you may face penalty points and a fine. 5. Do not litter in the toll station area. Littering on the highway can result in a 50 yuan fine, and it can easily cause rear-end collisions, leading to accidents, fines, and penalty points.

Does CVT mean automatic transmission?

CVT stands for automatic transmission. Here is an introduction about CVT: 1. Introduction: CVT represents the vehicle's transmission, specifically a continuously variable transmission. The difference between this type of transmission and other automatic transmissions is that the gear ratio is not intermittent but continuous, making it one of many transmission types. 2. Types: The first type is the AT transmission, known as the hydraulic automatic transmission, which was an early form of automatic transmission and is still used in some models today. The second type is the CVT transmission, a mechanical continuously variable automatic transmission, commonly used in Japanese models. The third type is the AMT transmission, an early form of transmission. The fourth type is the dual-clutch transmission, which features two sets of clutches and was first adopted by German vehicles.

What is the Discount for Flood-Damaged Cars?

Flood-damaged cars are generally sold at a 30% discount. Below is an introduction to the hazards of flood-damaged cars: 1. Electronic system malfunctions: The most vulnerable components in a car to water damage are the electronic systems. Although modern vehicles have waterproofing measures for electronic circuits, they cannot withstand heavy flooding or prolonged submersion. Once water submerges the engine compartment for an extended period, it can cause wire corrosion and short circuits. In minor cases, some electronic functions may fail, while in severe cases, it could lead to spontaneous combustion. 2. Engine failure: Generally, if a car's engine compartment has been submerged in water, do not attempt to start it. There is no guarantee whether water has entered the engine. If water has entered, a secondary start could result in a broken connecting rod in minor cases or complete engine failure in severe cases. In either scenario, the repair costs are extremely high, and the claims process is unlikely to be smooth.
