Carburetor Is Inevitable, Either It Is The Part Of Vw Jetta Dsg For Sale Or Not

Complex, fundamental and timeless. Although the era of electronic injection has long since taken over, the old carburetor has never retired, even today remaining the best choice for the most famous models, especially in the off-road world. For the buyer of VW Jetta DSG for sale or those who have not yet deepened their knowledge in the field of power for heat engines, or simply had abandoned this topic after too many start-up strokes, we introduce the operation of the carburetor and some of its fundamental components. As we know, the carburetor is that component that takes care of mixing the air with the petrol in the correct quantities to guarantee the regular functioning of the thermal unit during the bursting phase.

The Venturi Tube

To create a homogeneous mixture, the gasoline will be sprayed inside the carburetor through small components called sprayers and sprays. Gasoline, mixed in the right amount with air will create a highly flammable mixture which once introduced into the cylinder's combustion chamber will be able to guarantee maximum performance at all engine speeds. Obviously, the flow rate of the mixture varies according to the request for gas from the pilot. The auto accelerator is in fact connected to a valve (generally a gate or butterfly valve) present inside the carburetor which, by raising or lowering, will introduce a certain quantity of the mixture into the cylinder. To increase the air supply inside the carburetor the main duct called ‘Venturi tube’ was developed. This conduit, in the shape of cone trunks, is located between the diffuser and the fuel tank (the lower part of the carburetor) and creates a strong depression as its walls narrow. The atomized fuel mixes homogeneously with the high-pressure air creating a perfect mixture. 

Base Of Carburetor

A carburetor is based on the vacuum created by the engine to suck air and fuel into the cylinders. This system has been used for so long because of the simplicity behind it. The butterfly valve can open and close, allowing more or less air to enter the engine. This air moves through a narrow opening called Venturi. The vacuum is the result of the airflow needed to keep the engine running.  To get an idea of how a Venturi works, imagine a river that flows normally. This river moves at a constant pace and the depth is very constant over the entire length. If there is a narrow section in this river, the water will have to accelerate to get the same volume at the same depth. Once the river returns to its original width after the bottleneck, the water will still try to maintain the same speed. This causes high-speed water on the opposite side of the bottleneck to attract water that is near the bottleneck, creating a vacuum.

Inside A Carburetor

Thanks to the venturi, there is enough vacuum inside a carburetor to let the air pass through it to constantly suck in the gas from the Jet. Found inside the Venturi, the jet is an opening where the fuel from the float chamber can mix with the air before entering the cylinders. The float chamber contains a small amount of fuel, like a tank, and allows the fuel to flow easily into the jet when needed. When the throttle is opened, more air is drawn into the engine, bringing more fuel with it, which makes the engine more powerful. The main problem with this design is the fact that the accelerator must be opened for the engine to get fuel. The accelerator is closed to a minimum, so a minimum jet allows a small amount of fuel to enter the cylinders to keep the engine stalled. Other minor problems include excess fuel vapor escaping from the float chambers. A used car buyer can check the status and quality of the discussed issues before set the final VW Jetta dsg price.
