What Causes Engine Shaking When Turning on the AC?

The most common reason for engine shaking when turning on the air conditioning is dirty throttle body. Here are the causes of car shaking when AC is on: 1. Excessive compressor pressure: High pressure increases engine load, affecting the vehicle's stability. 2. Throttle body needs cleaning: During operation, carbon deposits accumulate in the throttle body. Excessive carbon buildup can block normal engine air intake, resulting in insufficient power to drive the compressor or barely enough to operate it. 3. Engine carbon deposits or aging: Idle shaking issues generally stem from engine problems. If the engine hasn't been cleaned for a long time or shows signs of aging, it will affect normal operation. 4. Spark plug carbon deposits: After prolonged use, spark plugs accumulate carbon deposits. If not cleaned promptly, this reduces engine torque output, causing AC-induced shaking.

What maintenance is required for a car at 40,000 kilometers?

At 40,000 kilometers, the maintenance items required for a car include changing the engine oil, oil filter, and spark plugs, as well as inspecting the wheel hubs and brake system. Below is a detailed introduction to car maintenance items: 1. Engine oil and oil filter replacement: This is primarily maintenance for the lubrication system. The main function of the lubrication system is to effectively lubricate the various components of the car engine to prevent excessive wear. The oil filter removes various impurities from the engine oil to ensure the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, a car should be serviced every 5,000 kilometers. 2. Air filter replacement: The air filter functions to filter the air before it enters the cylinders, removing impurities such as dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The gasoline filter is typically replaced every 20,000 to 25,000 kilometers. 3. Spark plug replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission fluid, the battery, throttle body, fuel injectors, and brake pads are all part of the inspection items during routine maintenance, and their maintenance depends on usage conditions.

What is the fuel tank capacity of the first-generation Geely King Kong?

The fuel tank capacity of the Geely King Kong is 45 liters, as officially announced. Owners who have purchased the Geely King Kong can also check this information on the vehicle's configuration sheet. The recommended fuel grade for the Geely King Kong is 92 octane, with a fuel consumption of 5.6 to 7.5L per 100 kilometers. A full tank can cover a distance of 600 to 803 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments. It is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the manufacturer is measured from the bottom of the tank to the safety level, with additional space from the safety level to the tank opening. This extra space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is added up to the tank opening during refueling, the actual amount of fuel may exceed the marked capacity.

What are the signs that brake fluid needs to be replaced?

The signs that brake fluid needs to be replaced include intermittent warning flashes of the brake indicator light during emergency braking or continuous braking. Below are the specific impacts of not replacing brake fluid for an extended period: 1. Corrosion of the braking system: Brake fluid is hygroscopic and tends to absorb water. If not replaced for a long time, the brake fluid can corrode the braking system, posing significant safety risks. 2. Formation of vapor lock: After absorbing water, the boiling point of brake fluid decreases, which can easily lead to insufficient braking pressure and affect braking performance. When the temperature rises to the boiling point, the water in the brake fluid will boil, generating a large number of bubbles. 3. Clogging of the brake system: Not replacing the brake fluid for a long time allows deposits and impurities in the brake lines to cause brake system malfunctions, impairing braking performance.

What does it mean when the steering wheel exclamation mark light comes on?

The appearance of an exclamation mark on the steering wheel indicates the Electronic Power Steering (EPS) indicator light, which should disappear immediately after the engine starts. The Electric Power Steering (EPS) system is a power steering system that directly relies on an electric motor to provide auxiliary torque. Compared to the traditional Hydraulic Power Steering (HPS) system, the EPS system offers many advantages. The EPS system mainly consists of components such as a torque sensor, vehicle speed sensor, electric motor, reduction mechanism, and Electronic Control Unit (ECU). The Electric Power Steering system evolved from the traditional mechanical steering system. It utilizes the power generated by an electric motor to assist the driver in steering operations. The system is primarily composed of three major parts: signal sensing devices (including torque sensor, steering angle sensor, and vehicle speed sensor), steering assist mechanism (motor, clutch, reduction transmission mechanism), and electronic control device. The electric motor operates only when assistance is needed. When the driver operates the steering wheel, the torque and angle sensors generate corresponding voltage signals based on the input torque and steering angle. The vehicle speed sensor detects the speed signal, and the control unit issues commands to control the motor's operation based on the voltage and speed signals, thereby generating the required steering assistance.

What does DISP mean in a car?

DISP on the car steering wheel stands for display screen. Here are the specific details about DISP in cars: 1. Function of DISP: DISP can switch the trip computer display data. Usually, the DISP button is located on the steering wheel. By pressing the DISP button, the driver can access information such as the vehicle's mileage, fuel consumption records, remaining fuel level, remaining driving range, etc. 2. How to use DISP: A short press on DISP can switch the information displayed on the central multifunction screen, while a long press followed by a short press allows for adjustments or changes to configurations like the clock. Pressing it once in the car will change the data displayed on the dashboard. For example: if the current display shows fuel consumption per 100 kilometers, pressing it once changes it to the remaining fuel level, pressing it again changes it to the trip mileage, and pressing it once more will display another type of information.
