What Causes the Suction Sound When Opening the Fuel Tank Cap?

Opening the fuel tank cap and hearing a suction sound is due to the internal pressure of the fuel tank being lower than the external atmospheric pressure. The fuel in the tank continuously evaporates, causing the internal pressure to rise. To mitigate the effects of these vapors and prevent direct emission of fuel vapors into the atmosphere, which would cause pollution, modern vehicles are designed with a pathway connecting the fuel tank to the engine's intake manifold, known as the EVAP (Evaporative Emission Control System). The EVAP system includes a charcoal canister and a control valve. The charcoal canister absorbs fuel vapors, and the control valve opens under certain conditions. When the valve opens, the negative pressure from the intake manifold draws the fuel vapors into the manifold, where they are burned by the engine. The negative pressure inside the fuel tank is generated during the opening of the control valve, fuel pump operation, and as the fuel level decreases.

What do China VI and China V mean?

China VI and China V represent the national automobile emission standards (China IV and China V). The following are the differences between China IV and China V: 1. Different sulfur content: The upper limit of sulfur content in China IV standard gasoline is 50mg/kg, while that in China V standard gasoline is 10mg/kg. 2. Different implementation times: The China IV standard was implemented in December 2014, and the China V standard was implemented in December 2017. 3. Different durability mileage: Compared with China IV, China V increased from 80,000 kilometers to 160,000 kilometers. 4. Different particulate matter particle numbers: Compared with China IV, the nitrogen oxide emission limit for China V gasoline vehicles is strictly required to be 25%, and that for diesel vehicles is strictly required to be 28%.

Is It Normal for Tires to Lose Air After a Month of Not Driving?

Tires can lose air not only due to obvious punctures or cuts but also because of poor repairs, aging valve stems, or damaged rims, which can lead to slow leaks. It is recommended to visit a retail store to check the actual cause of the air loss. Regularly inspect tire pressure, ideally once a month. Below are specific details about car tires: 1. Introduction: Car tires are one of the essential components of a vehicle, directly in contact with the road surface. Together with the suspension system, they help absorb shocks during driving, ensuring a comfortable ride and smooth handling. They also maintain good traction between the wheels and the road, improving the vehicle's traction, braking, and off-road capability. Additionally, tires bear the weight of the car, and their importance in vehicle performance is increasingly recognized. 2. History: In 1895, with the advent of automobiles, pneumatic tires saw widespread development. The first car tire samples appeared in France in 1895, made of plain canvas as single-tube tires with tread rubber but no tread patterns.

How to Use a Car Cigarette Lighter to Light a Cigarette?

Method for using a car cigarette lighter to light a cigarette: Turn on the car's power, insert the cigarette lighter into the power socket, and press down to lock it. The cigarette lighter will start heating up. When the heating wire turns red, the driver can use it to light a cigarette. After use, simply return the cigarette lighter to its socket. A car cigarette lighter functions similarly to a multi-outlet power socket in a household setting. It is an electronic device that connects to the car's power supply via a plug and provides multiple cigarette lighter sockets. The cigarette lighter socket is particularly useful for drivers who frequently use car electronics, as it can charge devices like mobile phones, MP3 players, and MP4 players. Additionally, besides lighting cigarettes, a car cigarette lighter can be equipped with a car inverter to convert the car's 12V, 24V, or 48V DC power into 220V AC power, which can be used for ordinary electrical appliances.

How many more years can a 2017 commercial-to-private vehicle be driven?

Commercial-to-private vehicles have a mandatory scrapping period of eight years. Below is a detailed introduction about commercial-to-private vehicles: 1. Commercial-to-private: As the name suggests, it refers to commercial vehicles being converted into private vehicles. The commonly referred-to commercial-to-private vehicles mainly refer to retired taxis converted to local license plates. After conversion to local license plates, the usage period remains 8 years, with mandatory scrapping 8 years from the date of manufacture, no further annual inspections, and no extension of the scrapping period. 2. Notes: Taxi-to-private and commercial-to-private are non-commercial, which are completely different concepts. Taking a car as an example, if the car was registered in 1999, if it is non-commercial, the mandatory scrapping deadline would be 2099, which is effectively an unlimited time. If it is a taxi-to-private conversion, then its mandatory scrapping deadline would be 2007.

How many models does the Yuchai 140 horsepower diesel engine have?

Yuchai 4110 National IV engine model, the specific model is YC4E140-41. The following is a detailed introduction about automotive diesel engines: 1. Definition: A diesel engine is an internal combustion engine that uses diesel as fuel. Diesel engines belong to the category of compression ignition engines and are often referred to as Diesel engines after their main inventor, Rudolf Diesel. During operation, the diesel engine draws air into the cylinder, which is highly compressed due to the movement of the piston, reaching a high temperature of 500-700°C. Then, fuel is injected into the high-temperature air in the form of mist, mixing with the air to form a combustible mixture that ignites automatically. The energy released during combustion acts on the piston crown, pushing the piston and converting it into rotational mechanical work through the connecting rod and crankshaft. 2. Engine within the diesel engine: The generator is the main power source for the diesel engine's operation. Its function is to supply power to all electrical equipment (except the starter motor) and simultaneously charge the battery when the engine is running normally (above idle speed).
