How to use usewith in a car?

usewith is used together with the external circulation. The meaning of usewith is to turn on the external circulation for defrosting. A reminder that when using the defrost function, it is necessary to switch to the external air circulation. Here are the relevant introductions: 1. When adjusted to usewith, the air conditioner forcibly activates strong defrosting, meaning the air conditioner automatically blows air to the front windshield and turns on the external circulation, quickly removing fog inside the car. This should be introduced in the car's user manual. 2. The fogging of the windshield is mainly caused by the temperature difference between the inside and outside of the car. If the temperature inside the car is high while the outside temperature is low, the windshield will also be cold. At this time, the moisture in the air inside the car will condense upon contact with the cold windshield, forming fog on the windshield and obstructing the view.

How Many Kilometers Can a New Energy Vehicle Travel per Kilowatt-hour?

Under normal circumstances, in the NEDC combined cycle, a new energy vehicle can generally travel between 5 to 8 kilometers per kilowatt-hour (kWh), depending on the energy consumption performance of different electric vehicles. However, according to the law of energy conservation, the greater the curb weight, the higher the energy consumption per 100 kilometers will be, meaning the distance traveled per kilowatt-hour will decrease. Introduction to new energy vehicles: 1. Definition: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in power control and driving, resulting in vehicles with advanced technical principles, new technologies, and new structures. 2. Classification: New energy vehicles include four main types: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar-powered vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices).

What does the EPC light on a car mean?

The EPC indicator light can illuminate in two scenarios: during the power-on self-test and under other conditions. The power-on self-test is an indication that the vehicle is checking the status of all sensors before driving. Typically, if the engine is not started, the light will turn off by itself after about 3 seconds. If the EPC light remains on after the vehicle starts or illuminates under other circumstances, the possible causes include faults in the engine intake system, throttle issues, fuel system problems, engine malfunctions, ECU control unit failures, or brake light faults. Below is a detailed explanation of the reasons for the EPC light illuminating under other conditions: Engine intake system fault: The EPC light will alert when the engine intake is obstructed or insufficient. Throttle fault: Carbon buildup is a common issue with the throttle. Additionally, dirt accumulation can affect intake, triggering the indicator light. Fuel system fault: Issues such as substandard fuel, fuel degradation, or poor fuel atomization can cause the light to illuminate. Engine fault: Insufficient engine pressure or problems with the intake valves and other powertrain components can also activate the EPC light. ECU control unit fault: Interference with the vehicle computer signals or false alarms from the computer may trigger the light. Brake light fault: Situations like non-functioning brake lights, faulty brake switches, or brake circuit issues can lead to the EPC light turning on. Solutions for when the EPC light illuminates: Troubleshoot the intake system, use fuel with the appropriate octane rating, clean the throttle, etc. Remove carbon deposits from relevant components. Re-flash the ECU with updated data. If the EPC light comes on, the owner can first try turning off the engine and restarting it to see if the light remains illuminated. If it does not come back on, there may be no issue, possibly just a temporary interference. However, if the EPC light stays on or frequently illuminates, it is advisable to drive to the nearest service center for professional diagnosis and repair to promptly address any safety hazards.

Why Can't New Energy Vehicles Charge to 100%?

New energy vehicles often fail to charge up to 100%, and the fundamental reason for this phenomenon lies in the current limitations of battery technology. For safety considerations, the charging current decreases when the battery reaches a certain level of charge. At a specific charging point (e.g., 99%), the current drops to just a few tenths of an ampere. There are two primary charging methods for new energy vehicles: 1. Public Charging Stations: As of August 2019, with the increasing number of brands and quantities of new energy vehicles, a significant number of public charging stations have been installed. When using public charging stations, it's important to distinguish between fast charging and slow charging. Generally, fast charging at public stations is sufficient, allowing the vehicle to be fully charged within 1 to 2 hours without disrupting normal driving. 2. Home Charging Equipment: Charging with home equipment is safer and more cost-effective. However, the charging speed is slower, typically requiring 8 to 10 hours for a full charge.

What are the reasons for poor air conditioning cooling in Honda XRV?

Here are the reasons and troubleshooting methods for poor air conditioning cooling in Honda XRV: 1. Excessive refrigerant: There is a specific proportion requirement for the refrigerant volume in the air conditioning system. Poor cooling performance is often caused by overcharging the refrigerant during maintenance. Troubleshooting method: Slowly release some refrigerant from the low-pressure side maintenance port of the air conditioning system. 2. Insufficient refrigerant: Poor cooling is mostly caused by minor leaks in the system. If there is too little refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will also decrease. As a result, the heat absorbed during evaporation in the evaporator will drop, leading to reduced cooling capacity. Troubleshooting method: Add refrigerant from the low-pressure side. 3. Excessive impurities in the refrigerant or refrigeration oil, causing minor blockages and poor cooling: If there is too much dirt in the refrigerant or refrigeration oil within the entire air conditioning system, the filter screen will inevitably become clogged, reducing the refrigerant flow capacity and increasing resistance. This will also decrease the amount of refrigerant flowing to the expansion valve, resulting in insufficient cooling capacity. Troubleshooting method: Stop the system for a while until the ice melts, and the refrigeration system will return to normal. 4. Reduced condenser heat dissipation capacity: Due to varying working environments, the condenser surface in front of the car engine may become covered with oil, dirt, or debris, reducing its heat dissipation capacity. Additionally, cooling fan issues, such as a loose drive belt, reduced fan speed, or high-speed problems, can also lead to decreased condenser heat dissipation. Troubleshooting method: Use a soft brush to clean the condenser surface, and promptly address any fan malfunctions.

What Causes the Engine Fault Light to Illuminate?

The engine fault light may illuminate due to the following 7 main reasons: Sensor malfunction: This includes sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, triggering the engine fault light. Fuel/oil quality issues: Failure to use the manufacturer-recommended fuel or engine oil may cause engine wear, leading to the fault light activation. Poor fuel mixture combustion: This can result in engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the fault light will illuminate as a warning. Causes include spark plug failure, ignition coil malfunction, fuel pump issues, or fuel line blockage. Turbocharging problems: Issues with the intake boost pipes or turbocharger can trigger the engine fault light. The most common is turbocharger damage, often accompanied by oil leaks, excessive oil consumption, power loss, metallic noises, or blue/black exhaust smoke. Intake system issues: Air intake problems may cause engine pipe blockages, potentially triggering the fault light. A dirty air filter that hasn't been regularly cleaned can lead to intake problems. Exhaust system problems: Exhaust faults can also cause the engine light to illuminate. Common causes include rear oxygen sensor failure, catalytic converter issues, or exhaust camshaft and bearing wear. Using leaded gasoline, certain oil additives, physical damage to the catalytic converter, or fuel system malfunctions may damage the catalytic converter. Anti-theft system malfunction: If the vehicle's electronic anti-theft system fails or the anti-theft controller doesn't match the engine ECU, the system may prevent normal engine operation while illuminating the fault light. When the engine fault light appears, follow these steps: First check if the engine operates normally. If there's shaking, black smoke, or other abnormalities, avoid restarting the engine. Note: Never restart if the light is red. If the engine can start, turn it off for 5-10 minutes. Without pressing the brake, push the start button once or turn the key halfway to the ON position (without engaging the clutch). The vehicle will perform a self-check for 5-10 seconds - observe if the warning light turns off. If the light remains on, visit a service center promptly. Technicians can use diagnostic tools to read trouble codes, identify the issue, and perform targeted repairs.
