Landi Renzo EM-H regulator designed for hydrogen-fueled internal combustion engines.

Landi Renzo announced it is developing an electronic pressure regulator for mid- and heavy-duty commercial vehicles with hydrogen-powered internal combustion engines (ICEs) with its partner, Bosch. The EM-H mechatronic pressure regulator is designed to manage and calibrate hydrogen delivery pressure according to the vehicle’s requirements. Designed and manufactured in Italy, two phases govern the functionality of the EM-H regulator: a mechanical input stage that reduces pressure from high to medium; and a subsequent entirely electronic stage which lowers pressure from average to desired value. The system features special valves to ensure protection of both the pressure regulator and downstream fuel line.
