<p>The invention relates to an arrangement for the supply of fuel to internal combustion engines with different mixing ratios of methanol and petrol, and continuous transition during operation between different mixtures thereof. The arrangement comprises a main tank (2) and a slave tank (4), which slave tank must be isolated from the main tank so that its mixing ratio is not varied by filling, enabling engine (1) to be started on the same fuel as that on which it was stopped. Engine (1) is supplied with fuel by a fuel pump (7) arranged in the slave tank (4), which fuel pump also drives an ejector (6) arranged in main tank (2), so that fuel is entrained from main tank (2) to slave tank (4). Only one fuel pump (7) is therefore required. Because ejector (6), in controlled dependence of the engine temperature, supplies the fuel to slave tank (4) through a rising pipe (20) which discharges above the highest fuel level in slave tank (4) and main tank (2) respectively, a safely isolated slave tank (4) is obtained during the warming up phase, followed by rapid mixing of the fuel in slave tank (4) with the fuel present in main tank (2).</p> |
