Abstract
An internal combustion engine, especially Otto engine, which utilizes fuel gas supplied in a low-temperature liquefied state for the combustion process. Heat exchange means are provided for effecting a heat exchange between the intake combustion air and the fuel gas such that the combustion air is cooled down prior to combustion by its use as a heat-emitting heat-exchanging medium for preheating the low-temperature liquefied fuel gas. In one preferred embodiment, the heat exchange means is a mixing carburetor arranged upstream of the engine combustion chamber and in another preferred embodiment of the invention, the heat exchanger means is a non-contact heat exchanger for effecting heat transfer without mixing of the combustion air and fuel gas.
