OMT Diesel Injection for Heavy-Duty Engines
In the world of diesel engines, efficiency, precision, and durability are non-negotiable — especially in marine, industrial, and heavy-duty applications. At the heart of these systems lies a vital component: the fuel injection system. And when it comes to trusted performance and engineering excellence, OMT Fuel Injection stands as a key player.
OMT (Officine Meccaniche Torino) is an Italian company with decades of experience in designing and manufacturing high-quality diesel fuel injection components. Known for their robust engineering and reliability, OMT systems power everything from commercial ships to industrial generators.
Let’s take a closer look at what makes OMT fuel injection systems stand out — and why they matter.
What Is OMT Fuel Injection?
OMT fuel injection systems are designed to deliver precise quantities of diesel fuel into the combustion chambers of internal combustion engines at high pressure. They ensure optimal atomization, timing, and spray pattern, which are crucial for:
- Efficient combustion
- Reduced fuel consumption
- Lower emissions
- Smooth engine operation
- Extended engine lifespan
OMT manufactures both mechanical and electronic fuel injection components, including injectors, nozzles, pumps, and complete injection systems tailored for large-bore engines.

Components in an OMT Fuel Injection System
A complete OMT fuel injection setup can include:
- Injection Pumps – Deliver fuel at high pressure, precisely timed to match engine demands.
- Injectors – Spray fuel into the combustion chamber with precise patterns and volumes.
- Nozzles – Critical for atomization, controlling droplet size and spray geometry.
- Fuel Rails & High-Pressure Lines – Transport fuel from pump to injector without pressure loss.
- Control Units (in electronic systems) – Manage timing, pressure, and duration based on load and sensor feedback.
OMT’s injectors and nozzles are compatible with both mechanical and electronic control systems, offering flexibility across modern and legacy platforms.
Advanced Engineering & Precision Manufacturing
OMT uses state-of-the-art CNC machining, heat treatment, and surface finishing technologies to ensure:
- Tolerances within microns
- Leak-free performance under extreme conditions
- Long-term resistance to cavitation, pitting, and thermal fatigue
Each component is rigorously tested for flow rate accuracy, spray pattern, and response time, ensuring consistent performance in all engine cylinders.
Application Sectors of OMT Systems
Marine Propulsion & Auxiliary Power
OMT systems are widely used in large diesel engines aboard container ships, ferries, fishing vessels, and tugboats. These systems offer fuel efficiency, emission compliance, and high uptime — critical for marine operators.
Power Generation
In backup generators and baseload power plants, OMT injection ensures reliable cold starts and stable operation, even in remote or off-grid environments.
Locomotives & Rail
Used in heavy rail diesel engines, where power density and fuel economy are essential for long hauls and tough terrain.
Oil & Gas Industry
From drill rigs to hydraulic power units, OMT injectors are trusted in engines that drive pumps, compressors, and critical infrastructure.
Key Features of OMT Fuel Injection Systems
What sets OMT apart from other fuel system manufacturers is their focus on high-performance, heavy-duty applications. Some defining features include:
- High-pressure capability: Engineered to handle the intense pressure required for efficient diesel combustion.
- Precision engineering: OMT components are manufactured with tight tolerances to ensure consistent fuel delivery.
- Corrosion-resistant materials: Ideal for harsh marine and industrial environments.
- Custom solutions: Designed to meet OEM specifications or retrofit into existing systems.
- Global service network: Spare parts and servicing available worldwide.
Applications of OMT Fuel Injection
OMT systems are used across a wide range of industries where engine reliability is mission-critical:
- Marine propulsion systems (main engines and auxiliary generators)
- Power generation plants
- Heavy construction equipment
- Locomotive engines
- Oil & gas industry (pumps, compressors, offshore rigs)
These engines often operate in extreme conditions — and OMT’s fuel injection systems are built to withstand those demands day in and day out.
The Importance of Fuel Injection in Diesel Engines
Fuel injection isn’t just about getting fuel into the cylinder — it’s about getting it there at the right time, in the right amount, and in the right form. Here’s why that matters:
- Performance: Proper injection timing and atomization ensure maximum power output and throttle response.
- Efficiency: Good fuel injection reduces fuel consumption by optimizing the combustion process.
- Emissions: Properly atomized fuel burns more completely, resulting in fewer harmful emissions.
- Engine Health: Balanced fuel delivery reduces stress on components and extends engine life.
OMT’s systems are designed to meet modern emission standards (such as IMO and EPA regulations) without compromising performance.
Maintenance and Support
Like all precision engine components, fuel injection systems require routine maintenance and occasional overhauls. OMT offers:
- Genuine spare parts
- Injector testing and calibration tools
- Field service and technical support
- Reconditioning services for injectors and pumps
Using authentic OMT parts and following the recommended service intervals is essential to maintain peak engine performance and avoid costly downtime.
