Where is the thermostat located?

The car thermostat is installed at the upper water outlet of the engine. The main functions of the thermostat are: 1. When the coolant temperature is relatively low, the thermostat remains closed, allowing only the coolant inside the engine to heat up. This is referred to as the 'small circulation.' 2. When the coolant inside the engine reaches a certain temperature, the thermostat automatically opens, connecting with the radiator to form what is known as the 'large circulation.' Benefits of installing a thermostat in the engine include: 1. Allowing the engine to reach its optimal operating state more quickly. 2. Reducing engine wear. 3. Improving fuel atomization. 4. Increasing the speed of cabin heating.

What is an H-type engine?

H-type engines arrange the cylinders in two rows with a 180° angle between them, meaning the two rows of cylinders are placed parallel to each other. Hence, this type of engine is also known as a horizontally opposed engine. More details are as follows: 1. The overall height of a horizontally opposed engine is significantly reduced, and its length is somewhat shortened, making the engine appear flatter and more compact. The direct benefit is a lower vehicle center of gravity, resulting in smoother driving, improved agility, and reduced risk of rollover. 2. Due to the high manufacturing costs and engineering complexity of horizontally opposed engines, currently, only two manufacturers in the world use them: Porsche from Germany and Subaru from Japan.

Can laundry detergent be used to wash a car?

No, laundry detergent should not be used when washing a car, as it can damage the car's paint. It is essential to use specialized car cleaning agents and follow the correct washing methods to ensure the paint remains undamaged. If proper care is not taken during regular car usage, the vehicle's paint can easily become damaged. Damage to the car's paint can affect its overall appearance. The car's paint consists of four layers, from the inside out: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. After the car body is fully assembled, robots immerse it in an electrocoating bath, forming the electrocoat layer on the surface. The primary function of the electrocoat layer is to prevent rust on the car body. Once the electrocoat layer is applied, robots spray the primer layer, which also helps prevent rust and enhances adhesion to the next paint layer. Above the primer layer is the basecoat layer, which provides the car's color. The various colors we see on cars are due to this layer. The clearcoat layer is the outermost paint layer, protecting the basecoat and enhancing the paint's gloss. Most minor scratches typically remain on the clearcoat layer.

How to Identify Power Batteries in Cars?

By external dimensions, the 18650 battery has a diameter of 18MM and a height of 65MM, which can be measured precisely with calipers. Identify its appearance and PVC; the quality and condition can help distinguish its advantages and disadvantages. Observe its appearance to determine if it is a brand-name battery. Use a multimeter to measure its voltage. There are many types of batteries on the market, such as lithium cobalt oxide, lithium iron phosphate, and lithium manganese oxide as cathode materials, with voltages of 3.7V, 3.2V, and 3.7V respectively, each having its own advantages. The cathode and anode materials of 18650 power batteries have smaller particles, and the separator and electrolyte between them have stronger conductivity. Power batteries support high-current discharge, and the resistance of the cathode and anode is also lower, which is designed to facilitate high-current discharge. The 18650 battery was first introduced by Japan's Sony Corporation. The capacity of 18650 power batteries is generally about half that of ordinary 18650 lithium batteries. For example, a capacity-type 2000mAh 18650 lithium battery would only have about 1000mAh in its power-type counterpart. The maximum charging voltage for ordinary capacity-type 18650 lithium batteries is 4.2V, while for power-type 18650 lithium batteries, it is around 3.65V.

How Many Kilograms of Antifreeze Does a Car Generally Need?

A car generally requires about 4 kilograms of antifreeze. Antifreeze prevents the coolant from freezing during cold winter parking, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. How to Choose Antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze comes in specifications with freezing points of -15°C, -25°C, -30°C, -40°C, etc. It is advisable to choose one with a freezing point at least 10°C lower than the lowest temperature in your region. Can Different Antifreeze Brands Be Mixed? It is necessary to use the same brand of antifreeze. Different brands may have varying production formulas, and mixing them could lead to chemical reactions between additives, rendering them ineffective. Antifreeze Replacement Cycle: For vehicles that operate for long periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, it should be replaced promptly, and the system should be cleaned.

Why Can't Spray Paint Achieve a Mirror Finish?

It may be due to incorrect spraying techniques. Here are some tips for achieving an even and glossy finish with spray paint: 1. Before spraying: Surface preparation is crucial before painting. For plastic parts, wash them with soap and a brush to remove dirt and grease, then lightly sand the surface with fine sandpaper or wet sandpaper. For metal parts, directly sand the surface with sandpaper and remove any residue. This enhances paint adhesion, ensuring durability and a smooth, even finish. 2. Location: It's best to spray paint outdoors on a windless, sunny day to prevent dust from settling on the surface. If indoors, ensure proper ventilation and keep away from fire sources. Hang or position the part upright for spraying. Spray paint uses a high-pressure method, similar to insecticide sprays. Shake the can vigorously several times to mix the paint. Hold the can vertically about 30cm from the surface and spray evenly by pressing the nozzle with your index finger. Spraying too close will result in large paint particles, affecting the finish. Apply light, even coats and use multiple passes. It's okay if the first coat doesn't fully cover—wait until it's mostly dry before applying the next. Repeat with light, even coats until satisfied, typically requiring at least 3 coats for best results. Avoid heavy application in one go, as this causes uneven coverage and runs, which are difficult to fix by sanding or leveling.
