What Causes Car Shaking and Engine Warning Light to Illuminate?

The reason for car shaking and engine warning light illuminating is incomplete combustion of the air-fuel mixture in the engine. When the mixture in the cylinders is too rich, symptoms such as engine knocking and shaking occur. When the mixture is too lean, the car may experience poor acceleration. Here are the specific explanations: 1. Substandard fuel: Using gasoline with a low octane rating can easily cause engine knocking. Although the ECU can detect engine knocking through the knock sensor and eliminate it by delaying ignition timing, if it exceeds the ECU's processing limit, knocking will still occur. In this case, the engine will shake violently, transmitting noticeable vibrations to the car body, and the engine fault indicator light will also illuminate. 2. Ignition system failure: Malfunctions in the spark plugs, high-voltage wires, or ignition coils can also cause the engine warning light to illuminate, along with symptoms like car shaking and insufficient power.

Why does the Yidong XT consume more fuel the longer it is driven?

This is due to excessive carbon buildup in the car's engine. Below is relevant information about the Yidong XT: 1. Introduction: The Yidong XT is a sedan model under Changan Automobile's product lineup. 2. Exterior: The Yidong XT features an 'Angel Wing' front grille design, where sharp lines seamlessly connect with the full-bodied surfaces. The creative combination of fiber-optic headlights and the grille resembles agile angel wings, exuding a youthful and handsome vibe. Additionally, the sharp surfaces, muscular waistline, and dynamic side profile give the vehicle a powerful forward momentum, evoking a sense of wind-whistling speed.

What does 5-speed mechanical automatic mean?

It means having five gear positions like a car, with five-speed transmission. Below are relevant introductions: 1. Automatic transmission vehicles: These refer to vehicles whose transmissions can automatically shift gears based on speed to achieve optimal power matching. Automatic transmissions are categorized into continuously variable (CVT) and stepped (X-speed), with significantly different shifting principles. 2. X-speed automatic transmissions: Currently, there are mainly 4-speed, 5-speed, 6-speed, and 7-speed variants. These can be understood as simply automating the traditional 4-speed, 5-speed, 6-speed, or 7-speed manual shifting processes (though the transmission structure is much more complex). Finer gear divisions result in better power matching performance, making the vehicle more fuel-efficient and the shifting process smoother.

What does it mean when the small car exclamation mark light turns yellow?

When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general malfunction, automatic transmission failure, abnormal tire pressure, and lighting system failure. Below is a detailed analysis of these four situations: General Malfunction: A triangle with an exclamation mark inside indicates a malfunction in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission failure warning light, indicating a transmission malfunction or transmission fluid level below the normal range. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark inside a horizontal line under a bracket represents the tire pressure monitoring warning light. This light turns on when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Failure: A yellow bulb with an exclamation mark is the lighting failure indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue. Additionally, a red exclamation mark inside a circle with a bracket represents a brake system warning, indicating either brake system failure or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents.

Do you need to shift to N gear when the car has AUTOHOLD?

No, you don't need to shift to N gear when using AUTOHOLD. AUTOHOLD is equivalent to an automatic handbrake. When you press the brake, the electronic handbrake will automatically engage. Combined with the auto start-stop function, since the brake is fully pressed, both AUTOHOLD and auto start-stop work simultaneously, the engine is in a shutdown state, and there's no need to consider gear shifting. It's important to note that the purpose of using the AUTOHOLD function is for convenience, such as when waiting at a red light. There's no need to change gears in such situations. However, when parked for an extended period, you should not keep the car in D gear. How the AUTOHOLD button works: AUTOHOLD is an extension function of the ESP system, controlled by the ESP components. When the vehicle is temporarily stopped and needs to restart shortly, the parking is handled by the ESP-controlled brakes. The computer uses a series of sensors to measure the vehicle's level and wheel torque, determining the tendency of the vehicle to move and applying an appropriate braking force to keep the vehicle stationary. This braking force is just enough to prevent the vehicle from moving, ensuring that when you press the accelerator again to move forward, there won't be a severe lurch. If the temporary parking exceeds a certain time limit, the braking system switches to mechanical rear-wheel parking, replacing the previous four-wheel hydraulic braking. When the vehicle is about to move forward, the electronic system detects the pressure on the accelerator pedal and, for manual transmission models, the clutch pedal's travel to determine whether to release the brake.

What are the solutions for tire pressure monitoring system malfunctions?

Generally, it is caused by a malfunction in the tire pressure detector or receiver module, and it needs to be resolved at a 4S shop or repair shop. Below is extended information about tire pressure monitoring: 1. Working Principle: The tire pressure monitoring system uses the sensing function of ABS to compare the rotational counts of the tires. Insufficient tire pressure shortens the circumference of the tire, resulting in different rotational counts compared to other tires during driving. 2. Tire Pressure Alert: The tire pressure monitoring alerts based on the comparison of rotational speeds by wheel speed sensors. Tire pressure display can be checked with a pressure gauge. While driving, the tire pressure loss display monitors the inflation pressure of the tires. If the inflation pressure in a tire is significantly lower than in other tires, the system will alert. When the internal pressure of the tire decreases, the working radius of the wheel changes accordingly, thus altering the rotational speed of the wheel.
