Abstract
A gaseous fuelled two-engine system comprises a high pressure direct injection engine as the main power source and an auxiliary fumigated engine that can be fuelled with vapor removed from a storage tank that stores the gaseous fuel in liquefied form at cryogenic temperatures. The fuel supply system comprises a cryogenic pump for raising the pressure of the fuel to the injection pressure needed for the high pressure direct injection engine, and the cryogenic pump is powered by the auxiliary fumigated engine.
