Multi-fuel operation of an internal combustion engine

摘要

A fuel change-over module (10) for a combustion engine (12) may be installed in a fuel supply system of the combustion engine (12). The fuel change-over module (10) may be configured to alternatively supply heavy fuel from a heavy fuel tank (102) or light fuel from a light fuel tank (104) to the combustion engine (10) via a fuel circuit (72) formed between the fuel supply module (10) and the combustion engine (12). The heavy fuel and the light fuel may have different temperatures. The fuel change-over module may comprise a fuel mixing tank (40). The volume of the fuel mixing tank (40) may be such that the total volume of fuel circulating in the fuel circuit (72) results in a desired temperature change rate and a desired change-over time when changing the type of fuel supplied to the combustion engine (12) by the fuel change-over module (10).
