Why does the car shake severely when starting in winter?

Winter car shaking when starting is caused by: insufficient combustion of gasoline in the engine, resulting in inadequate power supply, or stuck or clogged fuel injectors. Many cases of engine shaking are due to fuel injector blockage or sticking, which leads to insufficient fuel supply and power loss, thereby causing engine vibration. An engine is a machine that can convert other forms of energy into mechanical energy. It was invented in the UK and can be used both as a power generation device and as a complete machine including the power unit (such as gasoline engines, aircraft engines). Its types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), and electric motors.

What to Do When the Coolant Level in the Car is Low?

When the coolant level in the car is low, it needs to be replenished promptly. It is recommended that car owners regularly check the coolant level. If the coolant is below the minimum mark, it indicates a deficiency. The coolant should be of the same brand and model as the original. If a different brand or model is used, the original coolant must be completely drained before adding the new one, as different brands and models may have varying formulations. The full name of coolant should be antifreeze coolant, meaning it has antifreeze properties. It prevents the coolant from freezing in cold weather, which could otherwise crack the radiator or damage the engine block. Coolant is not just for winter use; it should be used year-round. As part of regular vehicle maintenance, the engine coolant should be replaced annually.

How to Check if a Car is Imported?

Methods to check if a car is imported: 1. Import customs declaration: Check if the car's identity information is an import customs declaration, which is the most authoritative and accurate method to determine whether a car is imported. 2. VIN (Vehicle Identification Number): The first letter of the VIN represents the country of production. Cars with a VIN starting with 'L' are domestically produced, including both independent and joint-venture brands. Cars with a VIN that does not start with 'L' are imported. 3. Common knowledge about cars: Some car brands are not domestically produced, such as Lexus, Subaru, Porsche, etc. These brands are sold in the domestic market as fully imported vehicles. Therefore, any model from these brands is definitely an imported model.

What is the appropriate engine starting RPM?

Normal RPM range is around 950-1300 revolutions per minute. Judgment based on actual conditions: Different car models from various brands may have varying starting RPMs due to differences in configurations and functions. Therefore, the specific RPM should be determined according to the actual condition of the vehicle. Different road conditions require different RPMs: When driving on regular roads, maintaining a starting RPM of around 1200 revolutions per minute is generally appropriate. If the vehicle is on an uphill slope or carrying a heavy load, the RPM can be increased according to the actual situation. Additionally, when starting the vehicle in winter, it's advisable to warm up the engine for about one minute while keeping the RPM below 2000 to avoid damaging the engine.

Can the front and rear oxygen sensors be interchanged?

Front and rear oxygen sensors cannot be interchanged. The car's exhaust system is equipped with oxygen sensors, which are installed before and after the three-way catalytic converter. These sensors are crucial for the vehicle's operation; without them, the car cannot function properly. The oxygen sensor located before the three-way catalytic converter is called the front oxygen sensor, while the one behind it is called the rear oxygen sensor. The primary function of the front oxygen sensor is to detect the oxygen content in the exhaust gases. It sends signals to the ECU, which then adjusts the air-fuel ratio based on this data. The rear oxygen sensor is mainly used to detect whether the three-way catalytic converter has failed. If the data transmitted to the ECU by both the front and rear oxygen sensors are the same, it indicates that the three-way catalytic converter has failed.

What Causes Motorcycle Idle Instability and Stalling?

The reason for motorcycle idle instability and stalling is excessive idle speed. Effects and solutions for low idle speed: Excessive idle speed makes ignition and starting difficult. Generally, a motorcycle engine can ignite at over 200 RPM, meaning it has already started but stalls due to the idle speed being too low to stabilize. Slightly increasing the idle speed can solve the problem. Reasons for stalling during gear shifting: Stalling can also occur during gear shifting, which is another sign of low idle speed. Of course, some chain-driven engines have a significant difference between cold and hot idle speeds. For example, the idle speed may be only 1,200 RPM when cold but exceed 2,000 RPM when hot, causing many people to hesitate to adjust it slightly higher. This is also one reason why consumers prefer pushrod engines due to the poor performance of domestic chain-driven engines.
