Fuel Pump

A fuel pump is a frequently (but not always) essential component on a car or other internal combustion engined device. They are two types of fuel pumps.

mechanical fuel pump

Prior to the widespread adoption of electronic fuel injection, most carbureted automobile engines used mechanical fuel pumps to transfer fuel from the fuel tank into the fuel bowls of the carburetor. A mechanical fuel pump is driven by the camshaft, or by a special shaft driven by the crankshaft. As the shaft turns, a cam passes under a pivoted lever and forces it up at one end.As engines moved away from carburetors and towards fuel injection, mechanical fuel pumps were replaced with electric fuel pumps, because fuel injection systems operate more efficiently at higher fuel pressures (40-60 psi) than mechanical diaphragm pumps can generate.

Electric pump

Electric fuel pump has its own electric motor and is operated by vehicle's ECU. Electric motor pushes fuel from fuel tank to the engine through fuel lines. Standard electric fuel pumps operate in 50-200 p.s.i. pressure rate. There are in-tank and external electric fuel pumps. In-tank fuel pumps are located in the bottom of the fuel tank. It is the most common type of setup. Electric external fuel pumps are usually mounted on a frame rail outside the fuel tank.

Cars with electronic fuel injection have an electronic control unit (ECU) and this may be programmed with safety logic that will shut the auto fuel pump off, even if the engine is running. In the event of a collision this will prevent fuel leaking from any ruptured fuel line. Additionally, cars may have an inertia switch (usually located underneath the front passenger seat) that is "tripped" in the event of an impact, or a roll-over valve that will shut off the universal fuel pump in case the car rolls over.

What is the function of the fuel pump?

Purpose of a Fuel Pump Module and Function of its Components. A fuel pump module serves two purposes. The first is to filter the fuel in a gas tank to prevent any debris from getting into the fuel pump. The second is, obviously, to pump gasoline from the gas tank to the carburetor or fuel injection system.

The history of Electronic instrument cluster

The first application of an electronic instrument cluster, in a production automobile, was in the 1976 Aston Martin Lagonda.In the United States they were an option in many motor vehicles manufactured in the 1980s and 1990s, and were standard on some luxury vehicles at times, including some models made by Cadillac, Chrysler and Lincoln.

Digital dashes were considered to be unpopular during the years when they were widely produced,They were hard to see in the strong sunlight or other bright light, they took away the sense of continuous acceleration that is provided by an analog speedometer, They were expensive to repair in the event of a malfunction. As a result of these issues, digital instrument panels were phased out of vehicles throughout the 1990s, and have been replaced with traditional analog gauges in most vehicles, including those from luxury divisions.

In the 2000s, digital speedometers have been produced in some hybrid vehicles, including the Toyota Prius and Honda Civic. Most digital speedometers have had green numbers displayed on a dark green or black background. The current model Honda Civic has an upper digital dashboard with white numbers against a blue screen, digital fuel and temperature gauges. The lower dashboard has an analog tachometer and digital odometer. Automotive head-up displays have seen applications in several cars, augmenting analog gauges with a digital readout on the windshield glass.

Automakers have begun offering vehicles with LCD instrument clusters that display "analog" gauges on screen, while integrating additional interactive features.

Once the electronic instrument cluster is broken, it is expensive to repair it in the original factory, but we can offer good quality and more cheaper item for you. Sacer specializes in car aftermarket for about 10 years, we upgrade the electronic instrument cluster by the market’s demands. Sacer company has many electronic instrument cluster for every car model, welcome to visit www.sacer-shop.com or www.sacer.com.cn if you are interested in this product.
