Ethylene glycol antifreeze cannot be mixed. The antifreeze used in cars includes ethylene glycol antifreeze, propylene glycol antifreeze, diethylene glycol antifreeze, etc. These antifreeze products have different colors because their chemical compositions vary. Mixing them can lead to clogging of the radiator pipes. Therefore, antifreeze of different colors should not be mixed. When using antifreeze in a car, it is essential to stick to the same brand of antifreeze. It is important to note that even antifreeze of the same color should be added with caution. Although they may share the same primary chemical composition, they often contain various functional additives, such as rust inhibitors and anti-scale agents, which require careful consideration during addition. If the car is low on antifreeze, do not mix it blindly. Always use the same brand and model of antifreeze to top it up. If the original antifreeze model is uncertain, it is recommended to flush the system before adding new antifreeze.

What is the steering wheel technique for driving in an S-curve?

The steering wheel technique for driving in an S-curve is as follows: 1. There are two directions for entering an S-curve, left entrance and right entrance. When entering from the left, the vehicle should stay as close to the right line as possible before turning the steering wheel to the left. Conversely, when entering from the right, the vehicle should stay as close to the left line as possible before turning the steering wheel to the right. This is done to account for the inner wheel difference and avoid the rear wheels crossing the line during the turn. 2. During the movement, the front of the car should follow the edge line. Taking the left entrance as an example, when the right corner of the car touches the right line, turn the steering wheel to the left one full circle, keeping the left corner of the car at a certain angle to the line on the ground, and follow the right line of the first curve of the S-path. This way, the car will not cross or go out of the line. When reaching the second curve, follow the same method as the first curve. Additionally, maintain a slow speed and check the left and right rearview mirrors to ensure the wheels do not cross the yellow line. Adjust the steering wheel based on the distance between the wheels and the yellow line to determine whether to turn more or less.

Who Invented the Internal Combustion Engine?

The internal combustion engine was invented by Étienne Lenoir. Lenoir was a Belgian-French inventor, born on January 12, 1822, in Mussy-la-Ville, Belgium, and passed away on August 4, 1900, in Seine, France. In 1859, he invented the first practical internal combustion engine. Here are some related introductions: 1. In 1801, French chemist Philippe Lebon used coal gas and hydrogen obtained from coal dry distillation as fuel to create an engine that mixed gas and hydrogen with air and ignited it to generate expansion force to drive the piston. This invention was hailed as a pioneering step in the history of internal combustion engine development. In 1859, Lenoir became the first to design and manufacture an internal combustion engine using illuminating gas as fuel. In 1862, French electrical engineer Lenoir successfully created a two-stroke horizontal internal combustion engine. Also in 1862, French scientist Alphonse Beau de Rochas, based on the thermodynamic research of Carnot (France), proposed the working principle of the four-stroke internal combustion engine. German inventor Nikolaus Otto designed and built the first four-stroke internal combustion engine in 1876. 2. In 1892, German engineer Rudolf Diesel was inspired by the dust explosion in a flour mill and pioneered the compression-ignition internal combustion engine (diesel engine), which was successfully developed in 1897, opening a new path for the development of internal combustion engines. This type of internal combustion engine was later mostly fueled by diesel, hence it is also called a diesel engine. In 1898, diesel engines were first used in stationary power generation units. In 1903, they were used as power for merchant ships, and in 1904, they were installed on naval vessels. In 1913, the first diesel-powered locomotive was built, and around 1920, diesel engines began to be used in automobiles and agricultural machinery.

How Often Should the Air Filter Be Replaced?

According to the car maintenance manual, it is generally recommended to replace the air filter every 20,000 to 60,000 kilometers. If the driving mileage is low, it is advisable to replace it every 12 months. The location of the car's air filter element varies depending on the intake method and the engine's structure. Cars have two types of air filters: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal wire mesh. Function of the air filter: It filters out particulate impurities in the air, ensuring that a sufficient amount of clean air enters the cylinders. It prevents airborne dust from being sucked into the engine, which can accelerate the wear of piston groups and cylinders. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. During operation, the engine inhales a large amount of air. If the air is not filtered, the suspended dust in the air can be sucked into the cylinders, accelerating the wear of piston groups and cylinders. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand particles from the air, ensuring that sufficient and clean air enters the cylinders. Dirty air filter: Using an excessively dirty air filter while driving can cause insufficient engine intake, leading to incomplete fuel combustion. This results in unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The car air filter is a device that removes particulate impurities from the air, consisting of one or several air-cleaning filter components. Its main function is to filter out harmful impurities from the air entering the cylinders to reduce early wear of the cylinders, pistons, piston rings, valves, and valve seats. Therefore, before air enters the cylinders, it must pass through the fine filtration of the air filter. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if it is found to have minimal dust and light blockage, it can be cleaned by blowing high-pressure air from the inside out and reused. Excessively dirty air filters should be replaced promptly.

What is the replacement interval for spark plugs?

Spark plug replacement interval: Under normal maintenance conditions, replacement is recommended after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is advisable to follow the instructions in the user manual. The following standards can be referenced for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance to assess its condition. A normal spark plug will have an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug will have a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug is contaminated with oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, showing signs such as blistering at the tip, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates that the wrong heat range was selected or that the air-fuel mixture is too rich, or that engine oil is leaking into the combustion chamber.
