Methods to determine if the charcoal canister is clogged are as follows: 1. The engine stalls due to the ventilation port of the charcoal canister being blocked by foreign objects; 2. Symptoms such as poor acceleration, jerking, and unstable or fluctuating idle speed occur; 3. Gasoline vapor or oil dripping appears at the atmospheric vent of the charcoal canister, indicating damage to the canister. If you are unsure how to assess it, you can consult a car repair shop for maintenance advice. The charcoal canister is used to store fuel vapors. Inside the canister, there are activated carbon particles that absorb fuel vapors, preventing them from being released into the environment when the fuel tank vents to the outside. Over time, clogging may occur, which can affect the normal operation of the vehicle.

How to Charge a Plug-in Hybrid at Home?

Methods for charging a plug-in hybrid at home: Use the included portable charging gun, plug it into a standard household 220V single-phase three-pin AC socket for charging, and ensure the socket is waterproof. Below is an introduction to plug-in hybrid vehicles: 1. Definition: Plug-in Hybrid Electric Vehicles, abbreviated as PHEV, are a new type of hybrid electric vehicle. Different from traditional gasoline-powered and electric-driven hybrids, the driving principle and unit of plug-in hybrids are the same as those of electric vehicles, with the only difference being the presence of an engine on the vehicle. 2. Advantages: Plug-in hybrid models effectively address the range limitations of pure electric vehicles and combine traditional power systems with pure electric power systems. When used as a pure electric vehicle, as long as the single use does not exceed the battery's provided range, zero emissions and zero fuel consumption can be achieved.

How Does the Crawl Control System Work?

Crawl control system works by allowing the onboard computer to intervene, controlling the brakes, throttle, and torque output. It can also release torque based on road condition feedback and electronically distribute braking force to all four wheels, ultimately preventing wheel slip. The driver only needs to steer and adjust the speed via the dashboard knob, without pressing the accelerator or brake. Related information: 1. The full name of the car's crawl mode is Low-Speed Cruise Driving Assist System, also known as the "fool-proof" off-road system. This system is particularly useful for inexperienced off-road drivers, as it helps them overcome challenging obstacles with ease. In low-range four-wheel-drive mode, activating the switch located on the right side of the gear lever engages the low-speed cruise assist, maintaining a speed between 1-5 km/h. Below the switch, there is a three-position rotary knob that allows the driver to toggle between three different speeds. 2. When climbing steep slopes or driving on special terrains such as snowy/icy roads, rocky paths, or sandy areas, the low-speed cruise assist system automatically controls the engine and brakes to maintain a stable low speed, ensuring excellent and stable passability. During driving, the driver does not need to focus on the accelerator or brake and can even remove their foot from these pedals. Simply concentrating on the road ahead and steering allows for easy navigation through difficult terrain, even reaching seemingly impossible heights.
