F02D19/0649 - CPC Classification

Classification description:

Controlling engines characterised by their use of non-liquid fuels, pluralities of fuels, or non-fuel substances added to the combustible mixtures peculiar to engines working with pluralities of fuels, e.g. alternatively with light and heavy fuel oil, other than engines indifferent to the fuel consumed characterised by the type of fuels Liquid fuels having different boiling temperatures, volatilities, densities, viscosities, cetane or octane numbers
