摘要： A filtration system is configured to provide clean fuel to a running combustion engine. The filtration system may be configured to be connected to a main fuel tank for storing contaminated fuel, and to be connected to a fuel supply of a combustion engine. A filtration circuit may include at least one filter, a first auxiliary fuel tank for containing fuel, and a first fuel pump configured to pump the fuel from the first auxiliary fuel tank through the filtration circuit back to the first auxiliary fuel tank. A second auxiliary fuel tank may be connectable to said first auxiliary fuel tank for receiving fuel from the first auxiliary fuel tank via a transfer valve. A control unit may be configured to control the transfer valve such that the first auxiliary tank is fluidly connected to the second auxiliary fuel tank only if fuel of a desired contamination level is contained in the first auxiliary tank.

摘要： A method of operating a gaseous fuel internal combustion engine comprises performing at least one measurement relating to the combustion of a mixture of gaseous fuel and air in a combustion chamber of an associated cylinder in a combustion cycle. At least one combustion parameter, for example, a start of combustion, is determined based on the at least one measurement. When the combustion parameter differs from a desired combustion parameter, an ignition device associated with the cylinder is controlled based on the comparison in order to control the combustion in the current combustion cycle.

摘要： A two-stage turbocharged internal combustion engine comprises a low-pressure stage turbocharger mounted at a first end side of an engine block and a high-pressure stage turbocharger mounted at the same first end side of the engine block. The respective turbochargers are mounted via a mounting structure, Which also accommodates the charge air coolers associated with the turbochargers. In order to obtain a compact arrangement and reduce a length of pipe connections between the different components, the different charge air coolers are mounted to mounting structure such that they overlap in a plan view of the internal combustion engine. Further, flow directions of charge air in the different charge air coolers are opposite to each other.
