Fuel Injection Pipes - Most Essential Components of Internal Combustion Engines

The fuel in internal combustion engines are delivered to individual fuel injectors through Fuel Injection Pipes. These pipes consist of a seat or pocket for each injector which serves as the inlet for the supply of fuel.

Fuel Injection Pipes

These fuel pipes are attached to the fuel pressure regulator. The engines consisting of multi fuel injection systems use these fuel pipes. Some of the multi fuel injection systems use individual fuels pipes with a fuel distributor to feed each injector. These fuel pipes are utilized for the division of supply of fluid into the entailed number of cylinders.

Fuel supply mechanism
High Pressure Fuel Injection PipesThe main factor before supplying the fuel is determining the quantity of fuel to be supplied according to the requirements of the engine. This is decided by the quantity or weight of air that is engaged by the engine to be utilized in the process of combustion. Airflow sensor is used by modern systems to measure the mass of air and then the result is sent to the engine control unit. The engine control unit uses the representing data of engine load or the quantity of power output to analyse the requirement quantity of fuel. TPS or the throttle position sensor offers the correct information. Other sensors in engines include crankshaft or camshaft position sensor, coolant temperature sensor and an oxygen sensor which decides the quantity of fuel combusted and operation of closed loop is allowed.
Types of injection systems
Fuel Injection Elements
Single point injection
At the throttle body a single injector is used in single point injection system. This type of system involves low cost and many supporting components of carburettor like intake manifold, air cleaner and fuel line routing can be reused. Thus the tooling and redesigning costs of these supporting components are postponed.
Central port injection
The Fuel Injection Pipes in central port injection system consist of poppet valves and the fuel is sprayed from the central injector at each port of intake and not in the central throttle body. In this system, the fuel pressure is like the system of single point injection.
Continuous injection
Continuous injection systems always or continuously have fuel flow at an inconsistent flow rate from the fuel injectors. Whereas the other injection systems of fuel have constant flow rate during the pulses and the fuels is provided during short pulses and not constantly. The system of continuous injections consists of single point or multi point units but not direct systems.
The other injection systems include Swirl Injection, Direct Injection and Multiport fuel Injection.
All types of fuel injection pipes are available online. People or organizations interested in these pipes can browse through the web and directly contact the manufacturers to avail these at market leading prices.
