Everllence’s Common-Rail Technology Surpasses 20M Operating Hours

Everllence recently announced that its medium-speed, common-rail (CR) technology has exceeded a cumulative total of 20 million operating hours across two generations: the original CR1.6 from 2004 and the CR2.2 that was brought to market in 2024. The company’s CR2.2 replaces CR1.6 on all newbuild engine types, providing precise control over injection parameters to optimize engine performance, emissions, and fuel efficiency.

The CR2.2 was integrated with Everllence’s 49/60DF engine in September 2024, and, before commercial availability, the injectors were successfully field-tested for over 12,000 operating hours on a 48/60CR engine and confirmed high component reliability. Per Everllence, the first 32/44CR engine prototype is currently being prepared for an initial test run using the new CR2.2 generation.

“20 million operating hours is a notable achievement that is born from 18 years of experience in the field involving over 600 engines, 5,500 cylinders, and across a broad range of applications and fuels,” said Michael Filous, Senior Vice President and Head of PrimeServ Germany, Everllence. “We recently brought production completely in-house, a key move that simplified the technical side of things. Everllence’s common-rail system is essentially a proven, modular system that easily adapts to different engine sizes.”

Compared to the CR1.6 generation, the CR2.2 offers up to 38% increased rail pressure across all applications (2,200 bar) and more than 33% longer time-between-overhaul intervals for most components. Additionally, the technology features 35% fewer high-pressure connections, reducing leakage risk and improving serviceability. It’s a platform for a wide range of fuels, including alternative sources like HVO and FAME.

ME-GI Milestone

Last week, COSCO Shipping Lines ordered Everllence’s B&W 8G95ME-GI Mk. 10.5 main engine, marking the company’s 2,000th order for a dual-fuel engine from its two-stroke portfolio. The engine features EcoEGR—Everllence’s exhaust gas recirculation technology. COSCO’s new unit falls under a bulk order for 12 ME-GI engines to be installed within 12 x 18,000 teu container vessels, currently under construction at Jiangnan Shipyard in China.

Everllence’s dual-fuel strategy and technology enabled many oceangoing ships to operate with alternative low-emissions fuels, showcasing environmentally friendly and reliable propulsion in the marine industry. The two-stroke engines can switch between fuels with minimal effort.

According to the company, more than half of its order book features dual-fuel engine power. The 2,000-engine figure is a cumulative total for all engine orders from the company’s two-stroke portfolio that includes ME-GI (methane), ME-LGIM (methanol), ME-GIE (ethane), ME-LGIP (LPG), and the recently announced ME-LGIA (ammonia) engines.

New Engine Launch

In November 2025, Everllence launched its new, dual-fuel ME-LGIA engine that uses the diesel principle and liquid gas injection concept. In addition to ammonia operation, the engine features additional safety measures such as containment systems, sensors, system ventilation, and double-walled piping developed specifically for ammonia fuel characteristics. The first ME-LGIA engine is scheduled for delivery in Q1, 2026, with bedding-in set for Q4, 2025.

The engine’s digital connectivity provides secure and reliable data flow from maritime vessels to Everllence shore-based monitoring, allowing the use of real-time engine and operational data to enhance performance, deliver remote assistance, and help shipowners operate more efficiently and sustainably. Data-driven insights will support decarbonization as new fuels, like ammonia, permeate the market.
