There is no need for a timing mechanism because each cylinder draws fuel from the discharge nozzle in the intake port as the intake valve opens. The Continental fuel injection system consists of four basic units: the fuel injection pump, the fuel-air control unit, the fuel manifold valve, and the fuel discharge nozzle.
What are the four main components of the Continental fuel injection system?
The Continental fuel-injection system injects fuel into the intake valve port in each cylinder head. [Figure 2-39] The system consists of a fuel injector pump, a control unit, a fuel manifold, and a fuel discharge nozzle. It is a continuous-flow type, which controls fuel flow to match engine airflow.
What is continuous-flow fuel injection system?
Continuous-flow fuel injection systems overview. … Fuel is sprayed constantly into the intake port of every cylinder, and the fuel/air mixture is drawn into each cylinder with the opening of the intake valve on the intake stroke.
At what locations on the engine are the fuel discharge nozzles installed?
The fuel discharge nozzle is located in the cylinder head with its outlet directed into the intake port. The nozzle body contains a drilled central passage with a counterbore at each end. [Figure 16] The lower end is used as a chamber for fuel/air mixing before the spray leaves the nozzle.
What are the functions of the Continental fuel manifold valve?
Fuel Manifold Valve (Spider)
This function is necessary to keep an engine from “running on” when in idle cut-off, and to reduce the vapor-lock potential. The upper side of the divider diaphragm is vented to atmospheric pressure.
What are three types of fuel injection systems?
The three major types of fuel injection are known as throttle body injection, multiport injection, and direct injection.
What is the main component of fuel injection system?
Abstract: The fuel injection system can be divided into low-pressure and high-pressure sides. The low-pressure components include the fuel tank, fuel supply pump and fuel filter. The high-pressure side components include a high pressure pump, accumulator, fuel injector and fuel injector nozzle.
What is the advantage of fuel injection?
Advantages of Fuel Injection:
Accurate air-fuel mixture and atomisation. Cleaner and more efficient combustion. Sharper and quicker throttle response. Better fuel efficiency or mileage.
What is fuel injection system in aircraft?
The fuel injection system mixes the fuel and air immediately before entry into each cylinder or injects fuel directly into each cylinder. Carburetor Systems. Aircraft carburetors are separated into two categories: float- type carburetors and pressure-type carburetors.
How does Aircraft fuel injection work?
Fuel injected systems use a fuel pump to push fuel through a metering system. Then, the fuel flows through injector lines to each cylinder. … However in some aircraft, the electric backup pump doesn’t provide enough pressure on its own to keep the engine running.
Where is the fuel injector nozzle?
Because fuel flows through the system in a continuous stream, regardless of piston position or stroke, the nozzle is placed upstream of the intake valve.
What are the fuel system components?
The fuel system is made up of the fuel tank, pump, filter, and injectors or carburetor, and is responsible for delivering fuel to the engine as needed. Each component must perform flawlessly to achieve expected vehicle performance and reliability.
What is the function of fuel injection pump?
An Injection Pump is the device that pumps fuel into the cylinders of a diesel engine. Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft.
What is Teledyne Continental fuel injection system?
The Continental fuel injection system is a multinozzle, continuous-flow type which controls fuel flow to match engine airflow. The fuel is discharged into the intake port of each cylinder.
What is a fuel injection and its component in aircraft?
A fuel injection system usually incorporates six basic components: an engine-driven fuel pump, a fuel-air control unit, a fuel manifold (fuel distributor), discharge nozzles, an auxiliary fuel pump, and fuel pressure/flow indicators. [
What gauge is connected to the flow divider?
The fuel flow gauge connects to the fuel manifold, or the flow divider. This is where the metered fuel is evenly divided among the four, six or eight fuel lines, leading to the cylinders. The fuel flow meter measures the pressure inside the flow divider, which is the fuel flow to the engine.
