In the world of diesel engines—where efficiency, power, and reliability are critical—fuel injection systems play a central role. Among the trusted names in this space is OMT (Officine Meccaniche Torino), a leading manufacturer of high-precision fuel injection components. Used in marine, industrial, and power generation sectors, OMT fuel injection systems are known for their durability, accuracy, and innovation.
In this blog, we'll explore what OMT fuel injection is, how it works, and why it's vital for high-performance diesel engines.
What Is OMT Fuel Injection?
OMT (Officine Meccaniche Torino) is an Italian company specializing in fuel injection systems, particularly for medium- and high-speed diesel engines. OMT fuel injection equipment includes:
Fuel injectors
Injection pumps
Nozzles
Common rail systems
Spare parts and overhaul kits
These components are designed to deliver precise quantities of diesel fuel into the engine's combustion chamber at extremely high pressures, ensuring optimal performance, combustion efficiency, and emissions control.
How OMT Fuel Injection Works
Like all diesel fuel systems, OMT injectors are built to atomize fuel into a fine mist and inject it directly into the combustion chamber at the exact right moment. Here’s how it works in a typical OMT system:
1. Fuel Pumping
High-pressure fuel pumps (often camshaft-driven or electrically actuated) pressurize diesel fuel and feed it to the injector.
2. Metering and Timing
In unit injectors or common rail systems, timing is controlled either mechanically or electronically. OMT offers solutions for both.
3. Injection
Fuel is delivered through a precision-engineered nozzle tip, where it’s atomized into a fine spray. This allows for clean and complete combustion.
OMT systems are often used in marine engines, stationary power plants, and locomotives, where efficiency and reliability over long operational hours are essential.
Key Features of OMT Fuel Injection Systems
