How to Interpret Data for Over-Rich Air-Fuel Mixture?

An over-rich air-fuel mixture can be identified by checking fault codes and long-term fuel trim values. Here are the details: 1. Fault codes: P0172 and P0175 both indicate an over-rich mixture, with the former referring to Bank 1 and the latter to Bank 2. During engine operation, the ECU adjusts fuel injection quantity via injector opening/closing times, primarily relying on voltage signals from various sensors. Short-term and long-term fuel trim values are key data for assessing air-fuel mixture combustion quality. If the sum of short-term and long-term trim values falls within ±5%, it indicates good engine combustion. 2. Long-term fuel trim: Also called the average learning value, if this value exceeds +35%, it means the ECU is continuously increasing fuel injection, indicating a lean mixture condition. Conversely, if the learning value exceeds -35%, it confirms an over-rich mixture.

What are the impacts of driving in heavy rain on the car?

Driving in heavy rain can be harmful to the car. Below is a detailed introduction to the damages it can cause: 1. Damage to the car body: (1) After the car gets wet in the rain, rainwater not only remains on the surface of the car body but also flows into the gaps underneath the car. When driving in the rain, mud and dirt from the road can also splash into these gaps. (2) When rainwater mixes with this mud and dirt, it forms grime that adheres to the gaps, hiding in hard-to-notice areas. If not cleaned properly, this can lead to rust on the car body. 2. Damage to the paintwork: Nowadays, rainwater in urban areas generally has high acidity. The acidic components in the rainwater can severely corrode the car's paintwork, causing irreparable damage over time.

How many hybrid models does Chery offer?

Chery offers two hybrid models: the Chery Arrizo 7-PHEV hybrid version and the Arrizo 7e plug-in hybrid version. Here is more information about hybrid vehicles: 1. Advantages: Like gasoline-powered cars, they can be refueled at gas stations without changing driving habits; governments and businesses can promote these products without investing in new charging infrastructure or gas stations; they have high fuel efficiency and superior driving performance. Hybrid vehicles use gasoline engines but can reduce fuel consumption during startup and acceleration with the assistance of electric motors. The internal combustion engine can be shut off, allowing the battery to drive alone, achieving "zero" emissions; the power performance is better than that of pure internal combustion engine cars of the same displacement, especially during startup and acceleration, as the electric motor can effectively compensate for the low-speed torque deficiency of the internal combustion engine; they reduce mechanical noise inside the car and use the electric motor during low-speed or idle conditions. 2. Disadvantages: The technology is not yet mature, and related products are priced too high; the cost of having two power systems (electric motor and internal combustion engine) is much higher than that of a single power system; they are not fuel-efficient during long periods of high-speed or constant-speed driving. The fuel-saving advantage of hybrid vehicles mainly relies on storing potential energy as electrical energy for energy conservation. Hybrid vehicles are more energy-efficient when frequently braking, decelerating, or starting and stopping. However, during long periods of constant-speed driving, their energy-saving effect is correspondingly reduced.

How to Handle Traffic Violations at the Traffic Police Station When Your Driving License is Confiscated?

Bring the violation receipt, ID card, and driver's license to the local vehicle management office where the violation occurred. The confiscation period of the motor vehicle driving license lasts until the penalty decision is made, and an administrative compulsory measure certificate will be issued. After handling the matter, you can retrieve your driving license. Here is additional information: Relevant regulations: Article 24 of the "Road Traffic Safety Law of the People's Republic of China" stipulates that the traffic management department of public security authorities shall implement a cumulative scoring system for motor vehicle drivers who violate road traffic safety laws and regulations, in addition to imposing administrative penalties. For motor vehicle drivers whose cumulative scores reach the specified value, the traffic management department of public security authorities shall confiscate the motor vehicle driving license, provide education on road traffic safety laws and regulations, and require them to retake the test; upon passing the test, the motor vehicle driving license shall be returned.

How to Repair a Faulty Fuel Level Sender?

Here are the methods to repair a faulty fuel level sender: 1. Normal wear and tear causing changes in the sliding resistance value, leading to inaccurate fuel level indication. In this case, a new fuel level sender needs to be replaced. 2. Impurities and gum deposits from the fuel adhering to the sliding resistance plate and contacts, causing changes in the sliding resistance value. This can be resolved through cleaning. Below are additional symptoms of a faulty fuel level sender: 1. The fuel gauge needle gets stuck at a certain position. 2. The fuel gauge suddenly drops to zero: The fuel level sender, also known as the fuel float, is a sensing device for fuel level height. It is usually made of foam plastic and, together with the fuel gauge, forms the vehicle's fuel level detection system. When the fuel level in the tank decreases, the fuel float sinks, moving the sliding arm and increasing the resistance, which in turn reduces the current returning to the fuel gauge.

What is the reason why the Land Cruiser differential lock light keeps flashing and cannot be turned off?

The Land Cruiser differential lock light keeps flashing usually because the differential lock is not engaged or disengaged. If this happens, it is recommended to go to a 4S shop and have a professional use a diagnostic computer to check the fault code before proceeding with repairs. Here is some information about the Land Cruiser: 1. Power: The Land Cruiser uses two engines, one is a 4.0-liter V6 naturally aspirated engine, and the other is a 4.6-liter naturally aspirated V8 engine. 2. Configuration: The Land Cruiser is equipped with comprehensive active safety technologies (including ABS anti-lock braking system, EBD electronic brake-force distribution system, VSC vehicle stability control system, etc.), ensuring safety performance when driving at high speeds or on slippery roads. At the same time, passive safety equipment such as 6 SRS airbags can provide all-round protection for the safety of drivers and passengers.
