What is a Subframe?

Subframe can be regarded as the skeleton of the front and rear axles, and it is a component of the front and rear axles. More details are as follows: 1. Definition: A subframe is not a complete frame, but a bracket that supports the front and rear axles and suspension, allowing the axles and suspension to connect to the "main frame" through it, hence the name "subframe"; 2. Function: The subframe serves to block vibrations and noise, reducing their direct entry into the cabin, which is why it is mostly found in luxury cars and off-road vehicles. Some cars also have subframes installed for the engine. Traditionally, vehicles without subframes have their suspension directly connected to the body panels; 3. Connection Method: Before the advent of subframes, the suspension linkage mechanisms of the front and rear axles were individual components, not assemblies. With the introduction of subframes, the front and rear suspensions can be assembled onto the subframe to form an axle assembly, which is then installed onto the vehicle body as a whole.

Difference Between China V and China IV

The differences between China V and China IV: 1. Different release dates: The China IV (National Phase IV) motor vehicle pollutant emission standard was released on December 30, 2005, while the China V (National Phase V) motor vehicle pollutant emission standard was released on September 17, 2013. 2. Different content: The main pollutants emitted by China IV vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). These emissions are controlled and reduced to below specified limits through technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices. The China V emission control level is equivalent to the European Euro 5 emission standard. From China I to China IV, each upgrade in the standard reduces vehicle pollution by 30% to 50%. 3. Different strictness: Compared to the China IV standard, the new standard reduces nitrogen oxide (NOx) emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Based on Shanghai's annual vehicle registration volume of approximately 350,000 units, it is estimated that newly registered vehicles can reduce annual NOx emissions by about 1,000 tons.

What Type of Fire Extinguisher is Best for Cars?

Currently, portable fire extinguishers are predominantly used for automotive fire protection. The main types of vehicle-mounted fire extinguishers available on the market include: dry powder fire extinguishers, ultra-fine dry powder fire extinguishers, carbon dioxide fire extinguishers, and water-based fire extinguishers. Relevant details: 1. Types: Vehicle-mounted fire extinguishers are specifically designed for car fires and consist of two main categories: non-pressurized hanging ultra-fine dry powder automatic fire extinguishing devices for vehicles, and pressurized hanging ultra-fine dry powder automatic fire extinguishing devices for compact cars. 2. Overview: Dry powder fire extinguishers are a type of fire extinguisher that can be classified based on the type of dry powder extinguishing agent they contain: ① Ordinary dry powder fire extinguishers; ② Ultra-fine dry powder fire extinguishers. Dry powder is a dry, free-flowing fine solid powder composed of fire-extinguishing base materials and additives such as moisture-proof agents, flow promoters, and anti-caking agents. It is primarily used to extinguish initial fires involving flammable liquids like petroleum and organic solvents, combustible gases, and electrical equipment.

How to maintain a 30 cm distance during hill start?

When going uphill, when the right front corner of the engine hood aligns with the roadside line at the 1/3 position, it indicates that the distance between the car body and the line is 30 cm. It is best to make adjustments using the left and right rearview mirrors. Below is relevant information about hill starts: 1. Reasons for stalling during hill start: Stalling during hill start often occurs because the left foot fails to stabilize the clutch when the vehicle reaches the semi-engagement critical point, which is when the vehicle begins to shake. If stalling occurs, depress the clutch and brake again, start the ignition, and restart the vehicle. 2. Key points to avoid rolling back during hill start: (1) Pull the handbrake tightly and release it slowly. (2) When depressing the foot brake, try to press it all the way down to maintain sufficient braking force. (3) Use the semi-engagement state of the clutch to overcome the resistance of the downhill slope.

What Are the Car Maintenance Items?

Car maintenance items include: changing engine oil and oil filter; air filter; fuel filter; transmission fluid; tire maintenance. Major maintenance is based on routine maintenance, in addition to replacing engine oil and oil filter, it also requires replacing the air filter and fuel filter. Major maintenance and routine maintenance can be alternated, with the interval varying by car brand, and should follow the car manufacturer's recommendations. More extended information is as follows: 1. Engine oil is the lubricant for the engine: To ensure the car's performance, the engine oil should be changed periodically, and its replacement cycle depends on the oil's effective time. The engine sucks in a large amount of air during operation, and the dust in it can accelerate the wear of the piston group and cylinder. 2. The role of the air filter: It is to filter out dust and particles from the air, ensuring that sufficient and clean air enters the cylinder.

Is the free expressway period calculated based on the time of entering or exiting the expressway?

The free expressway period is determined by the time of exiting the expressway. During statutory holidays, the free expressway policy for small passenger vehicles is based on the time of passing through the toll booth. Here is relevant information about the free expressway policy: 1. Charging Standards: The free period is calculated based on the time when the vehicle exits the expressway toll lane. For ordinary highways, it is based on the time when the vehicle passes through the toll booth lane. In other words, if you enter the expressway during the charging period and exit during the free period, you will not be charged. Conversely, if you enter during the free period and exit during the charging period, you will be charged. 2. National Policy: According to national regulations, only 7-seat and below small vehicles can enjoy the free expressway toll policy during the four statutory holidays: Spring Festival, Qingming Festival, Labor Day, and National Day.
