Everllence has announced a significant milestone, achieving 20 million operating hours with its medium-speed, common-rail technology. This accomplishment spans two generations of common rail systems: the original CR1.6, launched in 2004, and the newer CR2.2, introduced in 2024.
Michael Filous, Senior Vice President and Head of PrimeServ Germany at Everllence, emphasized that this achievement reflects 18 years of expertise, involving over 600 engines and 5,500 cylinders across diverse applications and fuels. He noted that the company’s recent decision to bring production in-house has simplified technical processes, enhancing the adaptability of Everllence’s modular common-rail system to various engine sizes.
The CR2.2 model replaces the CR1.6 in new Everllence engine types, providing precise control over injection parameters to improve engine performance, emissions, and fuel efficiency. Compared to its predecessor, CR2.2 offers several advancements, including up to 38% increased rail pressure, over 33% longer overhaul intervals for components, and 35% fewer high-pressure connections, which reduce leakage risk and enhance serviceability.
Everllence has already integrated the CR2.2 into its 49/60DF engine as of September 2024, and preparations are underway for an initial test run of the 32/44CR engine using this new common-rail generation. Prior to this, CR2.2 injectors were successfully field-tested for 12,000 operating hours on a 48/60CR engine, demonstrating their reliability.
