How to Connect the Three Pipes of a Charcoal Canister?

Charcoal canisters are generally divided into single-chamber, dual-chamber, and triple-chamber types, with single-chamber and dual-chamber being the most common. Typically, a charcoal canister has three pipe connections, and the specific connections are as follows: 1. The T port (Tank port, also known as the adsorption port) connects to the fuel tank, the P port (Purge port, also known as the desorption port) connects to the engine intake pipe, and the A port (Air port, also known as the atmospheric port) vents to the atmosphere. 2. These three ports must never be connected incorrectly, as the T and P ports are usually directly connected inside the charcoal canister. For example, if the A and P ports are reversed—meaning the A port is connected to the engine intake pipe and the P port vents to the atmosphere—gasoline vapors will bypass the activated carbon and vent directly into the atmosphere, causing environmental pollution and effectively rendering the charcoal canister useless.

Can Car Wheels Be Swapped Front to Back?

Wheels of the same specifications can be swapped front to back. Swapping wheels of the same specifications does not affect the vehicle's driving. However, if you want to swap the entire tire, you need to perform tire dynamic balancing because swapping tires can affect the stability of the vehicle. Not performing dynamic balancing may cause the vehicle body to shake during driving. The relevant introduction to car wheels is as follows: 1. Introduction One: The wheel hub is the cylindrical metal component inside the car tire that supports the tire with the axle as the center. In layman's terms, it is the part where the axle is installed in the center of the wheel and is an important component connecting the brake drum (brake disc), wheel disc, and half-shaft. 2. Introduction Two: The so-called "tire" is the rubber part of the "wheel." It is soft itself, so the barrel-shaped part inside the tire that supports the tire and is mounted on the axle is called the wheel hub. Due to different language habits, many people have different names for the wheel hub.

What causes severe shaking when the car reaches 100 to 120 mph?

Severe shaking of the steering wheel when the car reaches 100 to 120 mph may be due to resonance. Below are the related explanations for the shaking: 1. If the shaking is not severe, it is a normal phenomenon. All cars will experience shaking at high speeds, but the timing of the shaking varies depending on the car. For example, a Santana may shake at 100 km/h, while a Mercedes-Benz might only shake at 200 km/h. This phenomenon is known as car resonance. 2. Car resonance refers to the phenomenon where, when driving at a certain speed (usually between 100 to 120 km/h), the vibration frequency of the car reaches the resonance frequency, causing the car body to shake violently. Every car will experience resonance, and when it reaches a certain speed (usually between 100 to 120 km/h), you can feel significant noise and vibration. 3. If the shaking is very severe, the most likely cause is tire-related issues. For example, tire camber or toe, foreign objects on the tire surface, wheel rim deformation, poor tire balance, loss of wheel balance weights, excessive steering linkage play, insufficient tire pressure, etc., can all cause the car to shake, leading to steering wheel vibration.

Will Fuel Vehicles Really Be Phased Out?

The claim that fuel vehicles will be phased out by 2025 actually originated from a meeting of the Ministry of Industry and Information Technology. The average lifespan of fuel vehicles is between 10-15 years. Even if used without restrictions, the last batch of fuel vehicles, based on their average lifespan, would still be in use until around 2035, meaning they won’t be phased out during this period. Below are some drawbacks of fuel vehicles: 1. Point One: The energy density of gaseous fuels is low. Natural gas vehicles carry less fuel, resulting in shorter driving ranges compared to gasoline vehicles. Gaseous fuels occupy a certain volume in the combustible mixture in the cylinders (the volume occupied by liquid fuel in gasoline engines is negligible), which means less work is done when using natural gas as fuel in the same cylinder working volume. 2. Point Two: Most natural gas engines currently in use are modified from original gasoline engines. As a result, vehicles converted to natural gas often experience a power reduction of about 10%-20%, leading to phenomena such as poor uphill performance and slow acceleration response, as reported by drivers. Most diesel vehicles converted to natural gas using a "dual-fuel" modification method do not exhibit these issues, but the modification components are structurally more complex. 3. Point Three: Since current natural gas vehicles are modified from original gasoline or diesel vehicles, most of the original fuel systems are retained. Adding a natural gas fuel system, especially the gas tank, reduces the effective space of the original vehicle and increases its weight.

What are the reasons why the trunk button of the 12th-generation Crown cannot open?

The reasons why the trunk of the Crown cannot open include: a short circuit in the trunk module of the battery, a blown fuse, a dead remote key, insufficient power, or a damaged trunk lock. Below is relevant information: Toyota Crown: The Crown is a mid-to-large-sized car brand under the Toyota Group, first launched in Japan on January 1, 1955, and has now exceeded the 13th generation. The domestic Crown engines come in three types: 2.5L, 3.0L, and 4.3L. The first two are designed with a V6 cylinder and 24 valves, while the 4.3L engine features a V8 cylinder. They are equipped with the Dual VVT-i system for intelligent variable timing on both intake and exhaust valves. Domestic Crown: The domestic new Crown comes in four models and seven grades, all powered by a 3.0L dual VVT-i engine, paired with a 6-speed automatic transmission, and built on the FR (front-engine, rear-wheel-drive) platform, combining smooth handling with ample driving power.

What does it mean when the lottery shows 'obtained quota'?

When the lottery shows 'obtained quota,' it means that you have obtained a car purchase quota through the lottery system. Below are the specific details of the new 2021 lottery regulations: 1. Addition of family unit application channels: Quotas are divided into two types—ordinary quotas where 'car-free families' and individuals participate in the same pool, and new energy quotas where 'car-free families' are ranked based on their points. 2. Quota preference: In 2021, 60% of new energy quotas will be prioritized for 'car-free families,' increasing to 70% in 2022 and 80% after 2023. For ordinary quotas, 'car-free families' will have a much higher probability of winning than individuals, based on family points. 3. Changes in quota allocation frequency: The application period has been adjusted from monthly to two concentrated periods—January 1 to March 8 and August 1 to October 8 annually. The number of quota allocations has been reduced from six times a year to three times, with new energy quotas allocated in May and ordinary quotas allocated in June and December.
