F02D19/0631 - 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; Measuring or estimating parameters related to the fuel supply system; Determining the fuel pressure, temperature or flow, the fuel tank fill level or a valve position by estimation, i.e. without using direct measurements of a corresponding sensor
