How the common-rail injection system works

A common-rail system is a modern fuel injection technology for diesel engines. Unlike conventional systems, it separates pressure generation from the injection process. Its defining feature is the ability to generate and supply extremely high system pressures of up to 2,700 bar.

How a Common-Rail system works: The high-pressure pump delivers the fuel under high pressure into the high-pressure rail, where the rail pressure sensor monitors the pressure. From there, the fuel continues to flow under high pressure to the common-rail injectors, which atomize it finely and inject it into the cylinders at the exact time. The engine control unit regulates the entire process via electrical connections.

How the Denoxtronic exhaust-gas treatment system works

The system injects an aqueous urea solution (AdBlue) into the exhaust stream. In conjunction with an SCR catalytic converter, this process converts harmful nitrogen oxides (NOx) into harmless water and nitrogen, significantly reducing emissions.

How the Denoxtronic Exhaust-Gas Treatment System Works: The Denoxtronic exhaust-gas treatment system injects an aqueous urea solution, AdBlue, into the exhaust stream. Within the SCR catalytic converter, this solution enables a chemical reaction that converts harmful nitrogen oxides (NOx) into harmless water and nitrogen, thereby reducing environmentally harmful emissions. Based on engine and exhaust-gas data, the dosing control unit calculates and regulates the optimal amount of AdBlue required. A supply module pressurizes the AdBlue and delivers it to the dosing module. The dosing module, in turn, ensures the precise metering, atomization, and distribution of AdBlue into the exhaust pipe.

Quick Tips

Precision Fuel Injection

Precision Fuel Injection

Rough idling, hard starts, or poor fuel efficiency? Inconsistent fuel delivery reduces performance and increases emissions.

Tip: Check fuel pressure and injectors regularly to prevent costly engine damage.

High-Pressure Diesel Control

High-Pressure Diesel Control

Power loss or pressure faults signal unstable fuel delivery. Pumps, rails, and control valves maintain precise pressure for smooth operation.

Tip: Monitor live rail pressure to catch issues early.

Heavy-Duty Diesel Solutions

Heavy-Duty Diesel Solutions

Reduced torque, smoke, or uneven response? Worn high-pressure components affect reliability. Heavy-duty systems ensure durability under extreme loads.

Tip: Routine diagnostics and timely replacements extend engine life.
