are injectors part of the engine?
11355
Fuel injectors are parts of modern car engines that deliver fuel to the engine's combustion chamber, directly or indirectly. These small electro-mechanical devices are typically positioned at a certain angle to make sure the fuel is sprayed towards the engine's inlet valve or directly into the cylinder.

Engine coverage normally includes: Valvetrain. Water, Fuel, and Oil Pump. Fuel Injectors. Gaskets and Seals.

The symptoms of a stuck-open or incompletely closing fuel injector are quite different than an injector that is completely dead or partially clogged. In this case, there may be an odor of unburned fuel in the engine compartment, coming through the vents, or even out of the tail pipe.

Unlike carburetors, a Fuel Injection system is comprised of a complex set of electronics and sensors. In carbureted systems the fuel gets drawn from the tank, while in a Fuel Injected system it depends on a fuel pump installed inside the tank for a fine-grained control over fuel flow.

Function. A fuel pump pressurizes fuel and sends it through the fuel line to the fuel injectors. The fuel injectors atomize the pressurized fuel and inject it into the combustion chamber.

While fuel injector problems usually give warning, driving your vehicle for a long time with a clogged or faulty fuel injector can cause problems. ... Increased fuel consumption. A noticeable increase in tailpipe smoke and emissions. Rough idle and hesitation during acceleration.

All diesel engines use fuel injection by design. Gas engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke.

The primary function of the intake manifold is to evenly distribute the combustion mixture (or just air in a direct injection engine) to each intake port in the cylinder head(s). ... It may also serve as a mount for the carburetor, throttle body, fuel injectors and other components of the engine.

The injectors should not wiggle or move in and out. They are loose and leaking, causing a lean condition. You should replace both sets of o-rings.

Carbureted engines often use low pressure mechanical pumps that are mounted outside the fuel tank, whereas fuel injected engines often use electric fuel pumps that are mounted inside the fuel tank (and some fuel injected engines have two fuel pumps: one low pressure/high volume supply pump in the tank and one high ...

Direct fuel injection sprays fuel directly into the combustion chamber, while ported fuel injection sprays the intake manifold outside the valve. ... Throttle body fuel injection, while similar to a carburetor, has a separate throttle body with one fuel injector rather than fuel injectors located in each cylinder.

A stock 6.0L with a cam and headers will need at least 30 lb/hr injectors to supply sufficient fuel. LS engines also use two different styles of injectors with different connectors. The limitation here will be the size of the stock injectors.

Diesel injector coding – Ford Mondeo 2005. The first question that most technicians ask is why injectors actually need coding. The answer is that due to tolerances when the injectors are manufactured the injected fuel quantity may deviate between the actual and calculated fuel quantity.

All internally lubricated parts, engine oil, cooling hoses and lines. ... Also excluded is the starter motor, entire pressurized fuel system (in-tank fuel pump, pressure lines, fuel rail(s), regulator, injectors, and return line) as well as the Engine/Powertrain Control Module and/or module programming.

Functionally they're all the same. Make sure that you use a metal case if you have high pressure fuel injection. Of course, the smaller the filter, the more often it should be changed.

Your spark plugs are responsible for sparking combustion in your engine. If they misfire, or are working poorly, this can affect your gas mileage in a negative way. Having bad fuel injectors can cause bad mileage. ... This causes more fuel to be used, and will use up more gas than you need.
