What Are the Main Causes of Severe Engine Shaking When Cold?

There are several major causes of severe engine shaking when cold: carbon deposits, weak ignition, low cylinder pressure, and substandard fuel. The reasons for cold engine shaking can be summarized into the following three points: 1. Low ignition energy at low temperatures: The temperature inside the engine is insufficient, and both the fuel and lubricating oil are not warm enough. 2. Inappropriate air-fuel mixture ratio: The air-fuel mixture ratio is inaccurately adjusted, which occurs in both open-loop and closed-loop control systems. In vehicles with closed-loop control, the oxygen sensor's minimum operating temperature is 370 degrees Celsius. When starting the engine, the exhaust pipe temperature does not reach 370 degrees Celsius, so the oxygen sensor does not function, leading to ECU misjudgment. 3. Carbon deposits on engine valves and intake ports: If carbon deposits accumulate on the valves and intake ports of the engine, they can absorb a certain amount of fuel, causing the ECU to make incorrect judgments, resulting in shaking.

What is the Principle of Exhaust Braking?

Exhaust braking works by converting the engine, originally a power output device, into an air compressor that consumes power. Here are the details: 1. Introduction: Exhaust braking is widely used in large diesel vehicles. A regulating valve is installed on the engine exhaust pipe. Closing this valve increases the pressure during the exhaust stroke, utilizing the generated negative pressure to obtain braking force. 2. Usage Notes: (1) Engine braking cannot replace service braking for emergency stops, nor can it be used for parking brakes. (2) Engine braking can be used simultaneously with service braking. (3) The throttle pedal should be at the zero position.

What is the difference between 2.0t and 3.0t?

The differences between 2.0t and 3.0t are as follows: 1. Different displacement: The displacement of the 3.0t engine is higher than that of the 2.0t engine. 2. Different cylinders: The 3.0t engine has more cylinders than the 2.0t engine. 3. Different power and fuel consumption: The 3.0t engine has stronger power but also higher fuel consumption. Information about car displacement is as follows: 1. Displacement (Swept-volume): A specialized term in hydraulic transmission, referring to the volume of fluid inhaled or discharged per stroke or cycle. 2. Engine displacement: The working volume through which the piston moves from the top dead center to the bottom dead center is called the cylinder displacement; if the engine has several cylinders, the sum of the working volumes of all cylinders is called the engine displacement.

Can a National IV Vehicle Be Transferred and Re-registered?

If the destination region does not restrict the migration of National IV vehicles, the vehicle can be transferred and re-registered. Below is the procedure for vehicle transfer and re-registration: 1. Submit a relocation application: Go to the vehicle management office to submit an application for relocation, obtain a tracing number card, and specify that it is for outbound transfer or re-registration. 2. Submit required documents: At the designated window, submit the outbound transfer authorization letter, the 'Motor Vehicle Transfer Application Form,' the vehicle's license, the vehicle's plate number, and any other documents required by the local vehicle management office. Then, pay the corresponding fees and receive a receipt. 3. Collect the vehicle file: Three working days after submitting the plate, bring the receipt to the main office of the vehicle management office to collect the vehicle file, which includes the 'Motor Vehicle Transfer Application Form,' the vehicle inspection form, the chassis number, the vehicle's license, and vehicle photos. 4. Surrender the original plate and license: For vehicles that pass inspection, the original plate and license will be surrendered. The 'Motor Vehicle Registration Application Form' and the license will be annotated in the modification section with 'Transferred to the Vehicle Management Office of the Public Security Bureau (Office) of a certain province or region,' stamped by the issuing authority, and included in the file along with the 'Motor Vehicle Transfer Notification.' The file will then be handed over to the vehicle owner.

How Long Does It Take for a Car to Be Considered a Stock Vehicle?

For domestically produced cars, if the time from leaving the factory to delivery exceeds six months, it is considered a stock vehicle. For imported cars, if this period exceeds one year, it is classified as a stock vehicle. However, there is no clear legal definition for stock vehicles. For vehicles that remain stationary for months or even a year, components such as the battery, various fluids, rubber parts, paintwork, and related drainage holes can be affected. Maintenance tips for stock vehicles: 1. Store the vehicle in a clean indoor area to avoid damage from sun and rain; 2. Start the vehicle periodically in the correct manner to circulate the fluids; 3. Prevent excessive battery discharge by charging the battery regularly; 4. Move the vehicle occasionally to prevent tire aging. Following these steps will help prevent the vehicle from aging prematurely.
