Is There a Difference Between Intake and Exhaust Valve Springs in an Engine?

There is a difference between intake and exhaust valve springs in an engine. Length variation: The exhaust valve spring is longer, while the intake valve spring is shorter. Function of valve springs: The valve springs in an engine serve to ensure tight sealing between the valve and valve seat (or valve seat ring) when closed. They also counteract the inertial forces generated by the valve train during opening, maintaining constant contact between transmission components and the cam for proper control. As valve springs endure alternating loads, they must possess appropriate stiffness, sufficient fatigue strength, and service life to ensure reliable operation.

Will a car be photographed for driving with the trunk open to carry items?

Driving with the trunk open to carry items may result in being photographed. Driving with an unclosed trunk is illegal: It is illegal to drive a car with the trunk open due to carrying items.

If the trunk cannot be closed because of carrying items, the driver may face fines and penalty points if caught by traffic police. Precautions for carrying items in a car: Cars and minivans can be used to carry items without requiring an "operating permit." However, the space for carrying goods is limited to the trunk and the roof rack, and the height, length, and weight must not exceed the specified limits.

How Many Years Can a General Car Battery Last?

Generally, a car battery can last about 2 to 3 years, while the original battery in a new car can last more than 3 years. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Car batteries are categorized into conventional lead-acid batteries, dry-charged batteries, and maintenance-free batteries. Typically, the term 'car battery' refers to lead-acid batteries, which have a normal service life ranging from 1 to 8 years, depending largely on the vehicle's condition. Conventional lead-acid batteries have plates made of lead and lead oxide, with an electrolyte of sulfuric acid solution. Their main advantages include stable voltage, while the drawbacks are low specific energy (the amount of electrical energy stored per kilogram of battery), short lifespan, and frequent maintenance requirements.

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.
