Do you know what a snorkel is in off-road cars?
A Snorkel or breathing tube is one of the most important 4×4 accessories for off-road vehicles, and its existence greatly contributes to the health of the vehicle. The black pipes that are seen in abundance on off-road cars help these vehicles to breathe better. Off-road vehicles must have the necessary equipment to work properly. Off-road vehicles need these breathing tubes when they move in water and the water level is higher than the engine, so that the engine can breathe easily.
We all have seen SUVs that are decorated with accessories such as bullbar, canopy, etc. and surely you have realized the role of each of them. But what about those black pipes that extend from the hood of the car to the roof? Do you know what role they play in your car?
Offroad in itself is one of the most exciting disciplines of car racing and healthy recreation. Traveling to remote and rugged places that cannot be handled by any vehicle has made the off-road adventure reach its peak. The thought of crossing the river to reach the final destination will definitely increase your adrenaline. But common sense dictates that you should not rush into the water so as not to get yourself or your friends caught.
It is a general argument that rural and off-road routes are not up to standard and sometimes you need to cross large waterways and even rivers to reach your final destination. Good! However, there is a high possibility that the engine air valve will go underwater. A few drops of water entering the combustion chamber of the engine can be dangerous for it and may stop you in the middle of the road. Of course, the snorkel does not only prevent the passage of water, but by raising the air valve of the engine, it allows cool, clean and dust-free air to reach the combustion chamber of the engine. Since more SUVs and 4WD cars are used to go to off-road routes, most of the manufacturers’ attention is on these cars.
Snorkels have another important advantage, they allow cool air to enter the engine. As you know, the air intake duct is located under the engine door as a standard, and the air that enters the combustion chamber from this point is very hot and can hardly reduce the temperature of the engine. But as you can see, the snorkel raises the air intake duct up to the roof of the car and causes completely cool air to enter the engine.
Ykings4x44x4ykings4x4, as Australia’s central 4wd product shop, wants to tell you what a snorkel is, how it works and why an off-road vehicle should be equipped with such a part.
How does snorkel work?
Snorkel tubes are installed on 4WD or four-wheeled vehicles. These tubes, which have different sizes, go up from the air intake duct to the roof. The air required by the engine of these cars is supplied from a high altitude by means of snorkel tubes or breathing tubes, instead of coming from under the hood, so that the off-road car engine can breathe easily. The advantages of snorkels in off-road vehicles do not end there, but they also have another important use. Snorkels are actually designed so that more air is sucked into the engine at high speeds and can still improve engine efficiency.
Why are breathing tubes used in off-road cars?
One of the most important advantages of the snorkel is that the engine has access to clean air at a height higher than the housing. Most of the off-road riders like to cross the river with their car. For this, a breathing tube must be installed on the car to prevent the suction of water while crossing the river. If a car does not have a breathing tube when passing through water, there is a high probability that water will enter the combustion chamber of the engine. When driving off-road vehicles, a lot of pressure is applied to the engine, and as a result of this pressure, the engine needs cool air, so another reason for using these pipes is to provide cool and clean air for the engine. Also, off-road climbing causes dust in some situations, which prevents the entry of dust to a large extent and brings almost clean air to the car.
What materials are snorkels made of?
Snorkel manufacturers use a wide range of materials to make snorkels. Linear low density polyethylene (LLDPE) is the best material for making a snorkel due to its durability and resistance to ultraviolet rays. The polyethylene material is combined with carbon black and provides a black coating for the snorkel. Also, the black color does not fade easily with better resistance to UV rays. Plastic snorkels are usually made in one piece.
PVC pipes are commonly used to make snorkels because of their affordable price. However, snorkels made with these materials do not last as long as others.
Mild steel is another material used in the construction of snorkels. Although not as strong as original steel, this material allows you to shape it however you want. At the same time, it is much more resistant than PVC plastic.
Stainless steel is another material used to make snorkels. One of the advantages of such snorkels is their durability against risks such as rust and accidents. Of course, unlike plastic and PVC snorkels, they produce a lot of induced noise.
Types of snorkel
Snorkels are not very simple, they have a complex structure and the air that reaches the combustion chamber of the engine through them is filtered in several stages. Although they are useful for your car, they also have one drawback, which is creating a hole or vent to connect the snorkel to the air intake duct to the engine. snorkels are divided into two categories, which are as follows:
1. Vortex Snorkel
Vortex snorkels have a complex structure and its appearance is similar to a mushroom, which is due to the use of a turbine in it. When the car does not move and stops, the air needed by the cylinders is supplied from the lower parts of the snorkel, but when the engine speed increases, the need for air increases and as a result, the air suction increases. In this situation, the turbine used in the snorkel tube starts to It rotates and a vortex is formed above it, which causes the dust to be scattered around and delivers clean, filtered air to the cylinders. Of course, from the snorkel to the manifold (the device that sends the smoke out and delivers the air-fuel mixture to the combustion chamber) there are filters that filter the air and deliver it to the engine.
2. Ram Snorkel
The ram snorkel has a simpler structure compared to the Vortex. When the car is not moving, the air filters absorb the dust and the air reaches the engine normally. When the engine revs up, the air suction increases and the air enters the cylinders more strongly. As a result of the high air suction, the dust particles hit the walls of the snorkel and collect around it. Remember that the Ram snorkel is easier to clean than the Vortex snorkels.
A few tips about snorkeling
The design of the air intake chamber of snorkels is such that it usually rotates 360 degrees, so when it rains or snows, you can turn its cap and place it against the direction of rain. Keep in mind that this piece is designed in such a way that snow and rain do not penetrate into it.
If the rain penetrates into the cap of the car’s breathing tube, don’t worry because there are filters inside the cap that will remove the water.
When the speed of the car is high, its breathing is also higher and the air pressure entering the car increases, which increases the power of the engine and increases its efficiency.
When buying the snorkel, you must make sure that it matches the specifications of the car. For example, you cannot install a snorkel that is used for a 4-cylinder car on an 8-cylinder car because it does not work properly.
Therefore, if you intend to buy a snorkel for your 4WD and off-road vehicle such as Hilux, Ford Ranger, Land Cruiser, Prado, Amarok, Patrol, Jeep and any 4×4 vehicle, visit Ykings4x44x4ykings4x4, 4×4 accessories store in Australia.
