    • The invention relates to a fuel system for an internal combustion engine (2), which fuel system (4) comprises a first fuel tank (20), a second fuel tank (22), a main supply pump (26) and a transfer pump (28), wherein a first electric engine (M1 ) is arranged to operate the main supply pump (26), and a second electric engine (M2) is arranged to operate the transfer pump (28). The main supply pump (26) and the transfer pump (28) are reversible, and the fuel system (4) comprises a first flow circuit (100) for the fuel flow, through which the fuel is led at normal operation, a second flow circuit (200) through which the fuel is led at an operational disruption in the main supply pump (26), and a third flow circuit (300) for the fuel flow, through which the fuel is arranged to flow at an operational disruption in the transfer pump (28). The fuel system reduces the risk of insufficient or non-existing fuel supply to the internal combustion engine in the event of an operational disruption, and enables a method for continued operation, albeit with potentially reduced power. This also secures the operation of the internal combustion engine (2) and a vehicle equipped with such a fuel system.

    • A fuel supply system (1) for a motor vehicle is known in which the fuel flows through the fuel filter (6) of the fuel supply system in one direction only. In such a system, any sediments (10) that are present in the fuel are deposited on the filter material (8) so that the flow resistance of the filter material is gradually increasing. The aim of the invention is to provide a fuel supply system for a motor vehicle in which the flow resistance of the fuel filter remains virtually constant. To this end, a sedimentation pan (9) is provided in a housing of the fuel filter (6) below the filter material (8) which is mounted in the housing (7) in which pan the sediments (10) filtered off from the fuel (4) are deposited. An accumulator (15) is mounted in the fuel supply system that allows that the fuel (4) stored in the accumulator (15) scavenges the fuel filter (6) once the engine is switched off.

    • 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).
    • 本发明涉及一种用于向具有不同甲醇和汽油混合比的内燃机供应燃料以及在其不同混合物之间运行期间的连续过渡的装置。 该装置包括主油箱(2)和从油箱(4),从油箱必须与主油箱隔离,使其混合比不会因填充而变化,使发动机(1)能够在同一燃料上启动 像它被停止的那样。 发动机(1)由配置在从油箱(4)内的燃油泵(7)供给燃料,该燃料泵也驱动配置在主油箱(2)内的喷射器(6),使得燃料从主油箱 (2)到副罐(4)。 因此只需要一个燃油泵(7)。 因为喷射器(6)在发动机温度的控制依赖性下,通过分别在副罐(4)和主罐(2)中排出高于最高燃油位的上升管(20)将燃料供给到副罐(4) 在预热阶段获得安全隔离的液箱(4),随后将副罐(4)中的燃料与主箱(2)中存在的燃料快速混合。
