What Are the Hazards of Parking Without Turning Off the Engine?

Where is the engine of the Beijing Hyundai Fista from?

Beijing Hyundai Fista's engine is domestically produced. Taking the 2021 Beijing Hyundai Fista Elite Edition as an example, it is equipped with a 1.6T turbocharged engine, with a maximum power of 140kW and a maximum power speed of 6000 rpm. The maximum torque is 265Nm, and the maximum torque speed ranges from 1500 to 4500 rpm. The Beijing Hyundai Fista is a compact car with a body size of 4660mm in length, 1790mm in width, and 1425mm in height, a wheelbase of 2700mm, a fuel tank capacity of 53 liters, and a trunk capacity of 475 liters.

How often should car antifreeze be added?

Car antifreeze should be added approximately every two years. The method for adding antifreeze is as follows: 1. Open the car hood after the engine has cooled down; 2. Open the antifreeze reservoir cap; 3. Lift the vehicle and open the radiator drain plug, drain the old antifreeze, then reinstall the drain plug; 4. Lower the vehicle and pour new antifreeze into the antifreeze reservoir. Antifreeze is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems. Its functions include: 1. Excellent performance in preventing boiling in summer, preventing scale and corrosion throughout the year; 2. Preventing the coolant from freezing and cracking the radiator during cold winter parking.

What is the difference between synthetic oil and semi-synthetic oil?

Synthetic oil and semi-synthetic oil differ in the following aspects: 1. Base oil composition: Synthetic oil is blended from Group III, IV, and V base oils, while semi-synthetic oil uses Group III base oil. 2. Replacement intervals: Synthetic oil typically lasts for one year or 10,000 kilometers, whereas semi-synthetic oil requires replacement every six months or 7,500 kilometers. Engine oil, also known as motor lubricant, consists of base oil and additives. The base oil is the primary component of lubricating oil, determining its fundamental properties. Additives compensate for and improve any deficiencies in the base oil's performance. Its functions include: 1. Reducing friction and high temperatures; 2. Cooling and temperature reduction; 3. Cleaning and purification; 4. Shock absorption and cushioning; 5. Rust and corrosion prevention.

What is the cloth under the car chassis?

Engine plastic guard plate. Extended information is as follows: 1. Prevent sewage from entering the engine compartment during rain or snow. 2. Prevent small hard objects rolled up during driving from hitting the engine. These generally do not have an immediate impact on the engine, but over time, they can still affect the engine. This is why some unscrupulous dealers do not install guard plates—it saves costs and does not cause direct and rapid effects on the car, so it cannot be called a design flaw. Over time, it can be considered normal wear and tear. 3. Protect engine components and various pipelines, preventing damage caused by contact and friction with the ground under harsh conditions. 4. Improve the airflow under the car, reduce wind resistance and noise, thereby improving fuel economy and overall vibration and noise performance.

Why Can't the Bluetooth of Trumpchi GS4 Be Found?

The car Bluetooth may not be found because the Bluetooth in the vehicle is not turned on. If the vehicle Bluetooth is not turned on, the phone Bluetooth cannot find the vehicle Bluetooth within range; the distance from the vehicle is too far to find the vehicle Bluetooth; someone may have changed the name of the car Bluetooth, causing the old name not to appear in the search list; the car Bluetooth is set to not be found by other Bluetooth devices; the vehicle does not support Bluetooth function. The functions of car Bluetooth are as follows: 1. Eliminate noise and echo: Using advanced digital signal processors and language devices, suitable for any harsh environment, can eliminate background noise and echo, allowing both parties to enjoy high-quality call effects, with an effective distance of 10 meters; 2. Automatically identify mobile phones: No need for cables or phone holders to connect with the phone. You can control the phone without touching it, even keeping both hands on the steering wheel, using voice commands to answer or make calls, and users can make calls through the car's audio system.

What happens if you use 98 octane gasoline in a car designed for 95 octane?

Occasionally using 98 octane gasoline in a car designed for 95 octane won't cause issues, but long-term mixing of different octane ratings can lead to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance and potentially advancing the vehicle's major maintenance timeline. The appropriate gasoline grade should be selected based on the engine's compression ratio. Cars with compression ratios between 10.0-11.5 should use 95 octane gasoline, while those with higher compression ratios should use 98 octane. However, with modern technologies, compression ratio alone doesn't determine gasoline selection. High compression ratio engines can be tuned to use lower octane fuel due to other influencing factors like ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, higher octane gasoline has higher octane numbers and better anti-knock properties. 98 octane gasoline contains 98% isooctane and 2% n-heptane, while 95 octane contains 95% isooctane and 5% n-heptane. Occasional use of wrong octane fuel only requires switching back to the correct grade after consumption. However, long-term use of incorrect octane fuel can cause: Using lower octane fuel in high-performance vehicles may cause engine knocking. The significantly lower octane rating reduces gasoline's ignition point, causing premature ignition during compression stroke before spark plug firing. This creates resistance during piston's upward movement, making engine operation unstable. Mild knocking only increases noise without obvious engine damage, but severe knocking indicates serious engine issues affecting driving stability and causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring. Gasoline selection considerations: Choose gasoline with appropriate volatility based on ambient temperature. Highly volatile gasoline facilitates cold starts and smooth engine warm-up, but excessive volatility may cause vapor lock in fuel lines, preventing normal fuel pump operation and causing engine stalling.
