The 1,000 hp Advanced Combat Engine (ACE), developed by Cummins in partnership with the U.S. Army, will be showcased at Australia’s Land Forces Exposition in Melbourne from September 11-13.
Incorporating advanced technologies not currently available in diesel combat engines, the compact four-cylinder ACE is designed for infantry fighting vehicles and main battle tanks.
The 14.3-litre, two-stroke engine features opposed-piston technology and is equipped with dual Holset variable geometry turbochargers and a gear-driven supercharger for high power density and peak torque of 2424 lb-ft.
“Compared with existing best-in-class combat engines, ACE provides a 50 percent increase in power density and a 13 percent increase in fuel efficiency,” said Sam Jones, manager of Cummins Asia Pacific’s defence business.
“Being able to debut this engine at the Land Forces Exposition provides a great opportunity for defence personnel and Original Equipment Manufacturers (OEMs) to gain an insight into the performance capabilities of the next generation combat vehicles.”
