Fuel pumps are very vital components of any vehicle. Their major function is to deliver fuel from the tank to the engine. There are various categories of fuel pumps because they are developed to accomplish various functions and requirements of vehicles. Don’t forget to visit the https://www.osiaspart.com/Motorcycle-ATV-Fuel-Pump. Below are the five major categories of fuel pumps and how they function:
Electric Fuel Pumps
Most of the contemporary cars use electric fuel pumps particularly those that employ fuel injection systems. These pumps are always installed within the fuel tank and employ an electric motor to generate the required pressure that is needed to pump fuel to the engine. Electric fuel pumps are capable of delivering fuel at a steady pressure which is very essential for fuel injection systems. They are also more efficient and reliable as compared to mechanical pumps, thus they can supply fuel to the engine in a constant manner irrespective of the changes in the driving cycle.
Rotary Vane Fuel Pumps
Rotary vane fuel pumps are positive displacement types of fuel pumps. They are widely used in industries and several kinds of automobiles. These pumps contain a rotor which has blades that turn in a chamber. The vanes of the rotor slide in and out. Design chambers that have the fuel drawn into them and then the fuel is compressed to a higher pressure and then released. The rotary vane pumps are most suitable for use in areas where there is a need to have a continuous supply of fuel at high pressure as in the case of engines.
Mechanical Fuel Pumps
Some of the common applications of mechanical fuel pumps include; Mechanical fuel pumps were used in most of the older cars and carbureted engines. These pumps are mechanical and they are driven by the engine camshaft or crankshaft and lever or diaphragm for the creation of vacuum and pulling of fuel from the tank. The diaphragm begins to move up and down and this movement sucks fuel into the pump and then pumps it to the carburetor. This kind of pump is ideal for low-pressure environments but it is not ideal for today’s high-pressure fuel injection environment.
In-Line Fuel Pumps
In-line fuel pumps are installed outside the fuel tank but along the fuel line. These pumps are mostly applied as the second or the additional fuel pumps for increased pressure in high-performance or tuned cars. Just like the electric fuel pumps, in-line pumps employ an electric motor to pump the fuel and guarantee it has sufficient force to get to the engine. These components are mounted externally and are thus easier to get at and replace; this is especially useful in vehicles that may require frequent servicing or modification.
Conclusion
In conclusion, this is very important for anyone who is involved in car maintenance let alone tuning to have some basic understanding of fuel pumps and how they work. Mechanical fuel pumps are suitable for use in older models of automobiles while electric fuel pumps are suitable for modern engines. Inline fuel pumps, and rotary vane pumps, are the kinds of pumps that can be used in cars, high-performance vehicles, and industries. The kind of fuel pump that is appropriate for a particular car should be determined so that the engine would run optimally and the fuel pump would not wear out quickly.
