Basicaly,there are 3 types,Theres an electronic fuel pump,a mechanical fuel pump and a vaccum pump.....The electronic one is basicaly what it sounds like,it runs off 12 volt power to suck the fuel out of the tank.Some are in the tank and some are inline on the underbody.They suck the fuel outa the tank and push it through the lines to the injecters where it is injectected via electronic control by computer.....The other way is mechanically driven,which is run off a smaller cam inside the moter.The cam has a lobe on it which hits up against an arm on the pump which acts as a sort of plunger inside the housing to create the suction needed to to get the fuel from the tank to the injecters or carby....The other is the old vaccum trick.ONLY on older cars,20's style,lawnmowers,whipper snippers and small scale rc cars will have this...Basicaly it uses the pressure from the exhaust or crank case pressure to pressurise the fuel tank to force the fuel into the carby.CALLING ALL MECHANICS!! Can anyone explain how an oil pump on a car engine works?
you did not state what year of car.. older cars use a mechinal pump. newrer ones use a electric pump.
The fuel pump provides fuel delivery under pressure (modern) to the fuel injection system.The regulation is done by a fuel modulator or regulator (whatever you wanna call it) this sets delivery pressure per specs of system. The pump is electric, The curcuit consists of a fuse/relay/ignition switch./wiring
Easy, Fuel Pump it's in the Gas tank, pumps gas through the fuel lines, but first gas go through the fuel filter, than it continues its way,,,,than unused gas goes back to a reservoir kinda like the antifreeze reservoir, but this one is mostly at the bottom of the car....Fuel pumps receive energy to start when you turn the ignition on :-) Hope this helps.
I think you're a little confused. The fuel pump forces gas into either the injectors or carburetor which injects the air and fuel mixture into the cylinders where it is ignited by the spark plugs.
An oil pump is a separate entity entirely; it is part of the lubricating system of the engine. Usually driven off either the cam shaft or crankshaft, using gears, it sucks oil from the oil pan via an extension called a pickup and into channels that carry the oil to the areas where you don't want excessive wear to occur. The most common areas that receive oil are the cylinder walls (below the pistons, so you're not burning oil, which use oil rings to stop the oil from bypassing the piston), the crankshaft bearings, the camshaft bearings, rocker arms (which are the things that are controlled by lifters. Lifters are the parts that connect the valve gear to the camshaft), and various and sundry other locations in the engine . I hope I haven't made you even more confused, but there is a lot of difference between the fuel pump and the oil pump, obviously.
Clear? I hope so.
Be well. Hope I've helped.
Usually you have a fuel pump inside the gas tank,this pump is electric so this pump need electricity from your battery source to pump fuel to engine. Life span on domestic cars and truck is roughly 120000 miles vs Japense maybe twice as long.
Nope. The oil pump forces oil; into small shafts drilled through the internal parts of the engine. When these holes come to a part where 2 parts rub together, it lubricates these parts so they don't have as much friction (if you have no oil, the friction can cause the parts to heat up so much that they actually weld themselves together.) The gas gets into the cylinder by either being injected under pressure (the fuel pump supplies the pressure) into the cylinder (this is fuel injection), or it is simply sucked into the cylinder as the piston moved down in the cylinder. Only cars with turbos or superchargers have a pump for getting air and fuel into the cylinder - and these have nothing to do with the oil pump.
it pumps gas from the tank into the fixture(carburetor or injector)
pulls in fuel to the injectors
