common rail components

There are various kinds of vehicles and machines that we come across each day that are powered by diesel engines. They include long-haul trucks that ship goods, buses that ferry people around, generators that supply electricity and construction equipment at job sites. Common-rail system is one major component of the modern diesel engines. This system is vital to the process to make sure the right amount of fuel is injected into the engine at the correct temperature to actually combust that fuel for efficiency. This article will put the basic parts of common rail systems on display, what their job is in the system, and how it all works together.

The high pressure pump is driven off the engine. It gets to very high pressure, to unexpectedly high pressure sometimes, to pump fuel into the common rail. The common rail is simply a metal pipe that serves as a reservoir for the fuel. It catches the fuel before it gets injected into the engine's cylinder by the injectors. Each injector needs to squirt fuel into the chamber at the exact right time, which is determined by signals from the engine's control unit, called ECU.

The essential components of a common rail system

The injector's main stage then opens, and a powerful jet of fuel sprays into the cylinder through a nozzle. This atomizes the fuel into small droplets or a fine mist that combines with air and combusts. But the duration and timing of the fuel spray are critical during the fuel injection process. Getting this timing exactly right serves to ensure optimal fuel consumption, greater power and lower emissions. Common rail injectors operate under high pressure and high temperature, which requires regular maintenance of the common rail injector to function properly.

One of the outstanding facilities of common rail systems is the check and control of fuel pressure and the timing of the injection while the engine is in operation. This is achieved through the use of pressure sensors that monitor the pressure within the common rail and the fuel lines. The ECU receives this important data from these sensors. It then adjusts the pump and the injectors to ensure that the engine runs smoother and consumes less fuel.
