Cars are complicated, heavy and powerful piece of machinery – but without the means to process and pump fuel, they’re nothing but a large lump of metal. Oftentimes they’re a very nice looking hunk of metal, but ‘decoration’ isn’t exactly what most of us think when getting a vehicle.
No, we need our cars to be running at tip-top condition – otherwise, well, things fall apart pretty rapidly. Three specific details not many car owners are aware of are the importance of keeping your carburettor working (while keeping a good carburetor cleaner around), keeping a check on your benzine pump, and making sure you’re changing your filter often enough to ensure your system is running at proper efficiency.
- But first, before we get into exactly why this is so important, I’ll give you a quick run-down of how a benzine system works. To get started, your car stores liquid fuel – let’s take diesel in this case – in its tank. For a car to work, it needs to have a mechanism implemented that allows for benzine to flow from the benzine tank into the engine, delivered in controlled amounts and under low pressure. For such a precise and constant management of a combustion liquid, some hefty and fine-tuned machinery is necessary. This is where the pump comes in, along with the filter and the carburetor.
- A mechanical pump usually works by way of a diaphragm, inserted within the pump’s chamber and pulled or pushed by a pushrod attached to the engine’s crankshaft. The pushrod pulls the diaphragm down, allowing benzine to be pumped into the fuel chamber – then, it pushes the diaphragm up, closing the input valve and opening the output valve, through which the diesel is then forced into the carburetor.
- This is done first by pumping the benzine into a regulatory benzine bowl, which, when filled up to a certain point, forces the input and output of the fuel pump shut – so no more fuel can be pumped into the system until the benzine in the carburettor has been used sufficiently.
- The carburettor is where the magic happens. While the pump pumps petrol into the carburettor at a rate determined by its pushrod, it’s the carburetor that’s directly linked to a car’s accelerator, which activates the carburetor’s air flow. The faster air flows through the carburettor, the more pressure the carburetor is put under, and thus, it is drawn into the airstream more. The airstream and benzine passes through a butterfly valve (rotating disc) at the end of the carburetor’s throat, which receives air from an intake valve and fuel through a separate valve that distributes the fuel in tiny amounts through small holes in the carburetor’s most narrow point. Depending on the butterfly valve’s position, the airflow can be nearly completely unrestricted or nearly completely blocked, and everything in-between.
The valve, being the actual throttle, is what the accelerator pedal is linked to. This way, depending on the intake of air into the carburetor, a steady airflow can be maintained, while the actual speed of the car’s engine is regulated by the valve at the end of the carburettor.
This entire process is pressure intensive, which is why keeping it clean with a carburettor cleaner is important for efficiency’s sake. Now, carburetors and benzine pumps are incredibly important to a car – and they can also get pretty dirty, pretty quick.
While that may not seem like a big issue, it can be disastrous for your car’s performance and efficiency – and even worse, the diaphragm on which the pump’s mechanism relies can often break, causing a leakage of petrol into the crankcase.
Because of such hazards, it’s vital for any car owner to often have their car checked for signs of wear or obstructions in the system.
Filter is another important part
Speaking of obstructions in fuel, another pretty vital aspect to a car’s petrol system is the benzine filter. Believe it or not, cars need to have their petrol pretty darn well clean to work properly – otherwise, depending on the debris, the car’s internal systems could be scratched and damaged, or the debris could interfere with the it’s ability to burn, causing inefficiencies. Some of the most common debris is rust and paint chips from the car’s benzine tank, both of which can amp up the car’s petrol consumption.
In an engine running on diesel, these filters have a bowl-shape built into them to capture unwanted water in the tank, as diesel is a petrol of less density than water.
Water is disliked in diesel engines because of the component’s reliance on lubrication, and as you know, oil is very hydrophobic. This causes problems when not checked, which is why water control is an important job for filters.
There we have it – perhaps the most fickle aspect to a car’s essential ability to, well, function, is how it uses its petrol. Keeping the engine and the engine’s petrol system in top working condition is necessary for any car owner, because as with any complicated mechanical system, as soon as a single step of the rhythm begins to falter, the entire motion is in jeopardy!
A common issue you’ll encounter is a dirtied carburetor – which is why keeping a carburetor cleaner handy is so important. Without a clean shaft for the engine’s airflow, you’ll run into potential contamination and inefficiency, as well as wastage and an obstructed airstream – in short, your car’s acceleration will take longer, sucking more petrol and air and causing more wear and tear. Another thing to watch out for is a dirty filter.
Change your filter regularly to ensure it’s not obstructing the flow of petrol into the pump, nor letting debris enter the engine. Finally, make sure your pump’s diaphragm is in good shape – otherwise, you’ll be losing petrol and potentially damaging the engine!
