What is the corresponding gasoline octane number for motorcycle compression ratio?

Motorcycle engine compression ratio is 9.5:1, using 97 octane gasoline. Generally, the higher the compression ratio, the higher the required gasoline octane number. Below is relevant information: 1. Compression ratio: The minimum working volume of the cylinder, which is the total volume above the piston when the piston is at top dead center, is called the combustion chamber volume, denoted as Vc; while the total volume above the piston when the piston is at bottom dead center, which is the maximum volume of the cylinder, is called the total cylinder volume, denoted as Va. 2. Gasoline octane number: The high or low value only indicates the size of the gasoline's octane number, and different octane numbers should be selected based on the engine's compression ratio. Mid-range cars with a compression ratio between 8.5-9.5 generally should use 93 octane gasoline; cars with a compression ratio greater than 9.5 should use 97 octane gasoline.

What to Do When the Car Locks Automatically with the Key Still Inside?

If the car locks automatically with the key still inside and the engine running, it is likely due to a malfunction in the controller. You can either go home to retrieve the spare key or call a locksmith for assistance. Even with a mechanical lock, the car cannot be locked when the engine is running and no one is inside the cabin. After unlocking, it is recommended to replace the smart lock. The pros and cons of automatic locking are as follows: 1. Pros: Anti-theft feature, the car locks quickly after starting, preventing door-pull robberies during traffic jams or at red lights. It also protects children inside the car by preventing them from opening the doors while the car is moving. 2. Cons: In the event of a collision during driving, passengers may not have time to unlock the doors. In severe accidents, passengers might become unconscious, and if the locks remain engaged, rescuers cannot open the doors, which could delay timely rescue. In case of a fire, the consequences could be even more dire.

What Happens If a Car Is Left Idling for 7 Hours Without Turning Off?

Leaving the engine idling for an extended period can be harmful to the engine. When the car is parked with the engine running, it operates at idle speed, where the throttle opening is very small. This results in a low air content in the combustible mixture, leading to incomplete combustion and the formation of carbon deposits. Prolonged idling without turning off the engine can increase carbon buildup inside the engine. Below are some key points about idling: 1. Explanation One: Idling refers to the engine running without any load, only overcoming the internal friction resistance of its components, without delivering any external power. The minimum stable operating speed under these conditions is called idle speed, which is one of the five basic operating states of an engine. 2. Explanation Two: When adjusting the idle speed, the RPM should not fluctuate abruptly, as this can cause premature wear to the engine. Additionally, if you rest in the car for a long time with the air conditioning on and set to recirculate, the air quality inside the car will become increasingly polluted, with harmful gases gradually accumulating, posing risks to health and even life safety. Please exercise caution.

What are the peak and off seasons for car buying?

The off-season for the car market is from March to April and June to August, while the peak season refers to January and September to December. Below is relevant information: 1. Purpose of buying a car: First, clarify your needs and budget—what is the purpose of buying a car? Then, choose the appropriate brand, model, color, and configuration. Test drive to experience how it actually feels to drive. Consider your financial capability, the purpose of the car purchase, and future maintenance issues. 2. Avoid adding extra configurations: Some people are dissatisfied with certain configurations when buying a car and ask the 4S dealership to add them; some dealers forcibly add configurations under the pretext of vehicle delivery. This is not advisable because adding extra configurations can damage the original factory structure and cause wear and tear on some parts during disassembly and assembly, which can be very unsafe for future driving.

Is the Internet of Vehicles the built-in network of cars?

Internet of Vehicles is the built-in network of cars. According to the definition by the China IoT Industry Alliance, the Internet of Vehicles is a vast interactive network composed of information such as vehicle location, speed, and route. It can be regarded as a product combining IoT, intelligent transportation, vehicle information services, cloud computing, and automotive electronics technology. The benefits brought by the Internet of Vehicles are as follows: 1. Unimpeded and more convenient: In the era of the Internet of Vehicles, every car is equipped with GPS positioning and an "eye", allowing vehicles to upload road conditions to traffic management departments. Cloud control can then manage traffic flow, plan routes, and avoid congestion. 2. Safer and more secure driving: With the advent of the Internet of Vehicles, cars can actively explore their surroundings through their own sensors, connect to various traffic lights and control signals in the city, achieve automatic alerts, and avoid dangers. 3. Low-carbon travel and more environmentally friendly: In the process of building a low-carbon society, the intelligent transportation brought by the Internet of Vehicles will become a significant driver for energy saving and emission reduction, capable of undertaking 20% of the energy-saving and emission-reduction tasks. The smooth traffic network formed by people, vehicles, and roads will greatly reduce additional fuel consumption and pollution.

What causes a motorcycle to not accelerate when the throttle is applied after starting?

Motorcycle fails to accelerate when the throttle is applied after starting due to lean fuel mixture or poor crankshaft case sealing in two-stroke engines. Specific reasons are as follows: Lean fuel mixture in motorcycles: A lean air-fuel mixture results in insufficient gas pressure acting on the piston after ignition, prolongs combustion time, and causes engine overheating. Symptoms of a lean mixture include poor acceleration during operation, which improves when manually adjusting the choke or pumping fuel. However, acceleration weakness reappears without enriching the air-fuel mixture. Poor crankshaft case sealing in two-stroke engines: Air leakage due to failed crankshaft oil seal on the generator side; air leakage at the crankshaft case midline joint; air leakage at the interface between the crankshaft case and cylinder, or incorrect piston installation direction.
