Are Car Coolant and Antifreeze the Same Thing?

Car coolant and antifreeze are not the same thing. Here is a related introduction about coolant and antifreeze: 1. Definitions: (1) Coolant: The full name is antifreeze coolant, which means it has antifreeze functionality. As the name suggests, it serves two purposes: first, antifreeze, and second, cooling. Many people think coolant is only needed in winter, but this is incorrect. Coolant is not just for winter use; it is required all year round. Whether in extreme heat or cold, cars cannot do without coolant. Proper use of coolant not only protects the engine's cooling system and improves heat dissipation but also enhances engine efficiency and extends its lifespan. (2) Antifreeze: Antifreeze prevents the coolant from freezing in cold winter conditions, which could otherwise crack the radiator or damage the engine cylinder block or head. Many believe antifreeze is only for winter use, but in fact, it is needed throughout the year. 2. Differences: Antifreeze is not entirely equivalent to coolant. Coolant is equal to water plus antifreeze. In simpler terms, coolant refers to any liquid that can cool the engine, which can be either water or antifreeze. Water is a very basic form of coolant and is also limited by seasonal constraints.

What Octane Gas Does Geely Use?

Geely vehicles should use 92 octane gasoline as specified by the manufacturer. Below is an introduction to the functions of engine oil: Lubrication and Wear Reduction: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear of components, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby achieving the goal of reducing wear. Cooling: Engine oil can carry heat back to the oil tank and then dissipate it into the air, assisting the radiator in cooling the engine. High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine components back to the oil tank through circulation, and flush away contaminants generated on the working surfaces of parts through the flow of the lubricating oil.

How to Deal with a Stuck Manual Transmission?

Manual transmission stuck treatment method: First, slow down, then press the clutch pedal, pull over to the side of the road, and turn off the engine. The reasons for a manual transmission getting stuck include: 1. Problems with the synchronizer or shift fork; 2. Improper driving habits, such as pressing the clutch before releasing the throttle, causing the engine to stop supplying fuel while the clutch is not disengaged. This may not be noticeable in high gears, but in low gears, it can result in strong "jerking" sensations or even the engine stalling. During gear shifting, due to the synchronizer's function, the meshing gears will not engage until the rotational speeds are synchronized. However, improper operation, such as mismatched gear and speed, can easily lead to the transmission getting stuck after engaging the gear.

What is the working principle of the throttle valve?

Throttle valve working principle: The throttle valve is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. The accelerator pedal position sensor transmits the driver's acceleration or deceleration demands to the throttle electronic control unit (ECU). The ECU calculates the corresponding throttle position based on this information and sends control signals to the throttle actuator, which adjusts the throttle to the computed opening position. The ECU communicates with other electronic control units (such as the engine ECU, automatic transmission ECU, etc.), continuously correcting the throttle position using data from the throttle position sensor, engine speed sensor, and vehicle speed sensor, ensuring the throttle opening reaches the optimal position required by the driver.
