The aim of the research, which began in 2021, was to overcome “vapour lock”, or the tendency of LPG to change state from liquid to gas while it is still in the fuel delivery system.

The new injector design has two iterations: a high-pressure direct injector capable of fuelling applications from 25 to 200 kW per cylinder; and a high-flow port injector capable of “very high” gaseous fuel flow rates.

The multipurpose port injector for medium- and heavy-duty commercial vehicles is compatible with diesel, hydrogen, compressed natural gas (CNG) and dimethyl ether (DME) fuels.
