Cosworth's Lightweight Heavy Fuel Engine
Cosworth has been developing and manufacturing engine technology for more than 53 years, and has built a solid reputation for technological innovation and collaboration. At the 2012 AUVSI show, Cosworth will exhibit the advances in heavy fuel engine technology, as well as, show the benefits of integrating engine and power management systems.
Lightweight Heavy Fuel Engines
The choice of the US Navy for UE-UAV engine technology development, the Cosworth Heavy Fuel Engine (HFE) has been developed for a variety of unmanned system requirements. These engines range from propulsion to electric and hydraulic power generation.
Cosworth’s patented 2-stroke heavy fuel, compression ignition technology is used to deliver the highest achievable power-to-weight ratio combined with best-in-class fuel efficiency and tolerance. Engines can be air or water-cooled, and the combustion technology is scaleable to provide a wide range of outputs from 5hp to 50hp. Cosworth engines are designed to provide a balanced solution for fuel economy, power density and mass, as well as working in conjunction with the newly issued military mandates.
Portable Genset Technology
Cosworth’s patented 2-stroke engine technology demonstrator is not only lightweight and fuel efficient but packs 6kW of power density in a compact size. This size is five times smaller than other products of similar output, which preserves valuable space while generating needed electrical power on any vehicle.
Advanced Engine & Power Management
Cosworth’s engine management systems have demonstrated 8% fuel efficiency improvements on existing military vehicle engines while improving fleet reliability and availability. Our power management systems provide efficient electrical power strategies for military vehicles. These strategies eliminate the need for additional alternators, batteries and unnecessary operation of auxiliary power units. The Cosworth Intelligent Power-Management System (IPS) enables superior use of existing electrical power, improving reliability and simplifying fault diagnosis and repair.
Cory Parker, Director of Unmanned Systems at Cosworth commented, “From the beginning, we have collaborated with key customers, like the US Navy, to develop heavy fuel technology that supports their specific needs and mandate requirements. Attendees at the 2012 AUVSI show will be able to see our technical demonstrator showing the benefits of these key relationships.”
