Why can fuel injected engines use larger intake manifolds and still operate at low engine speed?
Intake runner size determines not only how much air is flowed but at what speed. The larger the runner, the more air can flow but at a slower speed. Keep in mind,
Proper Mixing of fuel and holding it in suspension with the air until delivered to the cyl is maintained by air speed or velocity, as used with carburation.
With direct fuel injection Fuel is injected directly into the cylinder rather than need to mix with incoming air before entering the cylinder, so air velocity is not as important as volume. As air has already been drawn into the cyl and then fuel injected under pressure as a mist, is introduced into the cyl and ignited.
The mixing of fuel /air and fuel suspension is bypassed when using a direct injection system. A faux injection system using carb type body to inject fuel into the manifold must use smaller runners than a true direct injection system. Fuel directed by on board computer/electronic sensors according to temp, timing, rpm and air volume. No pre-mixing of fuel/air required.
What else can I help you with?
Do fuel injected engines have spark plugs?
If it is a gas engine, yes. Diesel , no. Yes if it is gasoline engine,no if is a diesel.
Why injector is not used in petrol engine?
They can be. Petrol engines can be either fuel injected, or have carburetors. Smaller engines, like scooters, lawnmowers etc are almost always carburetted, while car engines are usually fuel injected these days.
Where is the fuel pump on a 1996 fuel injected 4-cylinder engine?
The fuel pump for fuel injected engines is commonly in the fuel tank.
Is there any automobile engine which runs without carburetor?
Yes, injected engines do not use a traditional carburetor. EFI gas engines do not have a carburetor, and diesel engines do not use a carburetor.
Why do most very small engines operate on 2 stroke?
Most small engines are two stroke because you can get more power from a smaller engine with two stroke rather than a four stroke engine. It takes less to cool and to operate the engine.
Can a 1991 Chevy K2500 350 engine be replaced with a 1987 Suburban 350 engine?
Yes these engines can be swapped because they are both fuel injected engines and should be very close if not identical.
How many manifolds in V8 engine?
On a V8 engine there is ( 1 intake manifold and 2 exhaust manifolds )
What does it mean when an engine can breathe?
Engines need air to operate, they take it in and expel it while running.
Where is exhaust-manifold located at on a Lincoln ls 2004?
On a 2004 Lincoln LS ( 3.0L V6 and 3.9L V8 engines ) Each of the engines has ( 2 ) exhaust manifolds They are located on each side of the engine , on the sides of the cylinder heads ( there is an exhaust manifold gasket , then the manifold , and they have a heat shield over the manifold ) Your vehicle exhaust system connects to the manifolds
What horsepower is 208 cc?
A 208cc engine would be a 8.32 Horsepower engine. The math goes like this... 1 x HP per each 25 cc for conventional engines. It is slightly lower for fuel injected engines, about 22 cc.
Did 1992 caprice ex police car have the LT1?
No, it did not. It had a throttle body injected engine, 3 different engines available. The LT1 260 HP "Corvette" engine did not debut until '94, ran thru 'til '96. That was a Tuned Port Injected motor.
Does a 1996 grand marquis have 2 exhaust manifolds?
Yes , it is a V8 engine , so it has 2 exhaust manifolds , 1 on each side of the engine
