People who don't go off-road or light off-road generally think that the snorkel is only installed to avoid engine water intake when wading in water, but you don't know that this is just one of its many functions!
The off road 4x4 snorkel is actually a common name for the people but it is not accurate. The more suitable name for it should be the “High intake-tube”.People who don't go off-road or light off-road generally think that the snorkel is only installed to avoid engine water intake when wading in water, but you don't know that this is just one of its many functions!
The off road 4x4 snorkel is actually a common name for the people but it is not accurate. The more suitable name for it should be the “High intake-tube”.
As its real role is to help the vehicle to increase the height of the air inlet. The higher it is, the better the air quality will be. And it will helpful for the engine working. Therefore, improving the vehicle's wading capacity is only an additional function. To improve the vehicle's wading capacity is It is not necessary to add such a high air intake.
It is obvious that the car engine cannot work underwater. Once the water enters the car, it will turn off. Every year, in heavy rain, many vehicles will be scrapped due to water inflow. This is because anything that enters the cylinder through the air inlet will be compressed about 10 times and then participate in the combustion. The air is very compressible and the water is not. When the piston moved up quickly in the cylinder, it was originally prepared to compress the air. I didn't expect that there was a lot of uncompressible water inside, so the tragedy happened. If you are lucky enough and you are only idling at the time, it usually only causes a flameout. If the engine speed is very fast at the time, usually the end is devastating damage! It is not the piston rod that breaks, that is, the crankshaft is deformed, and even the cylinder is broken. If you install the snorkel beforehand, although there is no guarantee that you will be unscathed every time you cross the river, the engine will at least not enter the water, so maintenance will be much cheaper in the future.
In short, you don't know what will happen in the future, so the off-roaders have to take precautions. The snorkel becomes a natural choice, especially since it is not expensive. However, here is a sentence, you must not use the old or poor quality wader for the sake of cheapness.
Driving in flying sand make you very excited! But this is also a great damage to the car's air filter! If your vehicle is driving on a very dry and dusty road, it is behind a fleet of cars. When the wheels of every car in front of you are whipped up with dust and sand and debris, your air conditioner has to carry a lot of dirt, and your engine needs clean air. The dust from the front of the vehicle has not been scattered for a long time. At this time, the density of dust in the air is different. The closer to the ground, the higher the dust content. At this time, if you install a snorkel, the air intake is nearly 1 meter higher than the original air inlet, so the dust absorbed is absolutely different. By increasing the air intake height, the snorkel can extend the life of your air filter and help protect your engine.
A good snorkel keeps the engine cool, clean and dry, and the lower the air temperature, the better the engine. Because of the high density of cold air, that is to say, the same volume can have more air intake, so that the combustion efficiency can be improved.
Although the height difference caused by the snorkel is actually close to none, don't forget the more important fact that the air temperature in the engine compartment is affected by the heat dissipation, which is higher than the outside air temperature. In some cases, the temperature difference It can reach 40 degrees Celsius, and the difference is not small. You might recall the difference in how powerful the car is on a cold morning and a hot afternoon.
Of course, the temperature of the part of snorkel in the engine compartment is indeed high, and the heat is transferred to the heat flow, but the temperature difference is very small, because the airflow flows quickly, and it is too late to absorb much heat. The second factor is that the high-speed flushing into the air inlet of the snorkel produces a large positive pressure, similar to the high-pressure supply, because the engine does not need to inhale much more.
Summary: Installing a high-quality snorkel is equivalent to installing a deep water permit, air filter, breathing booster, and engine hot air guidance for your car.
