EM-H Mechatronic Pressure Regulator

Landi Renzo is developing an advanced electronic pressure regulator for mid and heavy-duty commercial vehicles with hydrogen-powered internal combustion engines (ICEs). In collaboration with Bosch the two companies plan to produce and commercialize hydrogen-based fuel systems featuring the mechatronic pressure regulator to support the carbon-neutral operation of commercial vehicles.

Sitting at the heart of a fuel line, the pressure regulator serves as a decoupling element between the accumulation system and the combustion chamber’s fuel introduction system.

The EM-H mechatronic pressure regulator ensures optimal management and calibration of hydrogen delivery pressure according to the vehicle’s requirements, conveyed with a high level of accuracy and efficiency.

Designed and manufactured in Italy, two phases govern the functionality of the regulator: a mechanical input stage that reduces pressure from high to medium; and a subsequent entirely electronic stage that lowers pressure from average to desired value. The system features special valves to ensure the protection of both the pressure regulator and downstream fuel line.

The hydrogen-compatible EM-H can provide ideal pressure for the injectors at every operating speed and load, thus optimizing combustion for future high-pressure injection systems. To ensure safety, the pressure regulator is a completely sealed product.
