What Causes a Significant Power Drop When Turning on the Car Air Conditioning?

When the car's air conditioning is turned on, there is a noticeable power drop because the car's maximum power is around 100 kW, while its usual power output is only 20 kW to 30 kW. When the car is moving at a constant speed, suddenly turning on the air conditioning diverts some of the engine's power, making the car feel sluggish. The impact of turning on the air conditioning is particularly significant for small-displacement cars. The car's power output directly affects driving performance when the air conditioning is on. If the car's engine has higher power and displacement, the perceived power loss due to the air conditioning is less noticeable. Conversely, if the engine has lower power and displacement, the perceived resistance is greater. Tips for Using Car Air Conditioning: After starting the car, avoid turning on the air conditioning immediately. It is best to wait for a while before activating it. When the engine is cold, turning on the air conditioning increases the engine's load, which not only consumes more fuel but can also damage the engine. After turning on the air conditioning, it is advisable to open the windows immediately for ventilation before closing them. In summer, the temperature inside a closed car cabin can reach 60–70 degrees Celsius. High temperatures can cause interior materials to release toxic and harmful gases, so it is essential to ventilate the cabin before closing the windows and driving.

What is the REM wire in audio systems?

REM in audio systems refers to the speaker control wire, which is connected to the position where the car ignition key is turned on. Here are the details about REM: Installation in cars: Connect REM to the car key, 12V directly to the positive terminal of the battery, and GND to the negative terminal of the battery. Alternatively, GND can be connected directly to the car's chassis. This way, the audio system will automatically turn on when the car starts and turn off when the engine is shut down. Installation at home: A 12V-5A transformer is required. "REM 12V to +GND" is a terminal marking specific to car audio systems. REM is primarily used to control the startup and shutdown of the audio system and is generally a wire connected from the audio host.

How to Check the Year of a Vehicle Identification Number?

Methods to check the year from a vehicle identification number: In most standard VINs, the 10th digit represents the year. You can typically find the VIN on the vehicle's registration certificate, the engine's nameplate, or the driver's side door. The VIN is a 17-character code, commonly referred to as the '17-digit code,' which contains information about the vehicle's manufacturer, year, model, body type, engine code, and assembly location. Correctly interpreting the VIN is crucial for accurately identifying the vehicle model and performing proper diagnostics and maintenance. There are two main VIN formats: the first follows the ISO 3779 standard used by the European Union, and the second is primarily used in North America.

What are the symptoms of engine cylinder scuffing?

Vehicle cylinder scuffing symptoms include weak driving performance, difficulty in acceleration; elevated engine coolant temperature; unstable engine RPM operation accompanied by signs of stalling. Engine cylinder scuffing refers to the appearance of distinct longitudinal mechanical scratches and abrasions on the inner wall of the cylinder within the piston ring's movement range. In severe cases, adhesive wear occurs, leading to difficulties in engine starting or spontaneous stalling. Cylinder scuffing constitutes a major engine failure, fundamentally caused by the inability to form an oil film between the cylinder wall and piston rings/piston, resulting in poor lubrication or even dry friction. Specific causes of engine cylinder scuffing vary but generally fall into three categories: 1. Piston assembly-related causes; 2. Cylinder liner-related causes; 3. Operational usage-related causes.

What is the reason for the idle speed still being 1000 RPM after warming up the car?

The reason for the idle speed still being 1000 RPM after warming up the car is due to factors such as the idle switch not being closed. Below are related introductions about hot idle speed: Introduction to specific reasons: The most common issue is a malfunctioning idle control valve. If the idle control valve is faulty, it not only increases the RPM but also causes unstable speed. When such problems occur, it is essential to promptly check at a repair shop; otherwise, it can lead to a significant increase in vehicle fuel consumption. Introduction to the benefits of warming up the car: Reduces the engine's RPM; adjusts the car's state for adaptation; improves issues with the three-way catalytic converter, enhancing emissions.
