Should Gasoline Engine Cleaner Be Added Before or After Refueling?

It can be added either before or after refueling. Gasoline engine cleaner is designed to compensate for the quality issues inherent in fuel and the limitations in automotive mechanical manufacturing, thereby helping the gasoline engine overcome cold-start effects and crevice effects, and remove carbon deposits from intake valves and fuel injectors. Below are detailed explanations about it: 1. Introduction One: The main component of the cleaner is polyisobutene amine, which has a chemical structure similar to detergents, with one end being a polar group and the other end a non-polar group. 2. Introduction Two: The non-polar group ensures the product's solubility in fuel, while the polar group can adhere to the surface of carbon deposits or metal parts, serving to remove carbon deposits and prevent their formation, commonly referred to as the cleaning and maintenance functions.

What Does Oncoming Traffic Mean?

Oncoming traffic refers to the situation when a driver encounters another vehicle coming from the opposite direction while driving, hence the term "oncoming traffic." Oncoming traffic priority means that in narrow road conditions during oncoming traffic, the vehicle with the capability to yield must allow the vehicle without the capability to yield to pass first. Oncoming traffic yield is a type of traffic prohibition sign, indicating that the vehicle facing the sign must stop and let the oncoming vehicle pass first. Precautions for oncoming traffic: Observe traffic signals and signs carefully when encountering oncoming traffic. In conditions with poor visibility, reduce speed in advance. Avoid using emergency brakes or suddenly lifting the accelerator during oncoming traffic. Avoid oncoming traffic near obstacles. Avoid oncoming traffic in complex locations such as narrow bridges and narrow roads. Avoid not turning off high beams during nighttime oncoming traffic. Traffic rules impose many regulations on oncoming traffic. On roads without a centerline, narrow roads, or narrow bridges, drivers must slow down, keep to the right, and pay attention to the safety of non-motorized vehicles and pedestrians. When oncoming traffic is difficult, the party with the right-of-way must yield to the other party. On obstructed road sections, the party facing the obstruction must yield to the other party. On narrow slopes, the party facing the obstruction must yield to the other party. At night on roads without streetlights or with poor lighting, drivers must switch from high beams to low beams when the oncoming vehicle is more than 150 meters away. On narrow roads or bridges when encountering non-motorized vehicles, continuous use of high beams is prohibited.

What are the causes of a gasoline generator not generating electricity?

There are several reasons why a gasoline generator may not generate electricity: 1. Expired engine oil and gasoline: Engine oil and gasoline have a validity period of only three months. After three months, they lose their viscosity and become ineffective. 2. Prolonged inactivity of the machine: The fuel level in the carburetor drops, leading to corrosion that may block the fuel holes. Simply cleaning the carburetor can resolve this issue. 3. Damaged voltage regulator. 4. Wiring faults: Some wires may be loose or have poor contact. 5. Bearing wear: If the wear is not severe, it may cause local overheating of the bearings. Severe wear could lead to friction between the stator and rotor, causing local overheating in these components.

What does it mean when gasoline appears milky white?

This phenomenon is called engine oil emulsification. The main cause of oil emulsification is that during engine operation, some gases enter the crankcase through cylinder gaps. These gases consist of water vapor, gasoline vapor, and combustion exhaust. Mild oil emulsification is not a serious issue and does not affect the normal operation of the engine. Here are detailed explanations about it: 1. Explanation one: The appearance of white emulsion on the gasoline cap may indicate that water has mixed into the engine oil, causing the oil's viscosity to fail. This prevents proper lubrication of all rotating parts that require it, leading to severe consequences. 2. Explanation two: Once white emulsion appears on the oil cap, it should be taken seriously. After analyzing the cause, promptly take the vehicle to a service center for appropriate maintenance or component replacement.

What Causes Simultaneous Failure of Car Turn Signals and Wipers?

Simultaneous failure of car turn signals and wipers may be caused by a malfunctioning combination switch. Here's a detailed explanation: 1. Turn signals: Car turn signals are flashing indicators that activate when the vehicle is turning, alerting pedestrians or vehicles in front or behind about the intended direction of travel. 2. Wipers: Also known as windshield wipers, these devices are used to remove raindrops and dust from the vehicle's windshield, improving driver visibility and enhancing road safety.

What is an Auto Parts Market?

An auto parts market refers to a comprehensive marketplace specializing in the wholesale and retail of auto parts, as well as services like car detailing. Auto parts include vehicle accessories, components, and configurations. Below are some shopping precautions for auto parts markets: 1. Precaution 1: Check if the trademark and labels are complete. Genuine products have high-quality packaging with clear printing and vibrant colors. 2. Precaution 2: Inspect for any geometric deformations. Some parts may deform due to improper manufacturing, transportation, or storage. 3. Precaution 3: Examine the joints for smoothness. During handling and storage, parts can develop burrs, indentations, cracks, or damage at the joints due to vibration or impact, affecting their usability.
