Process for preparing start and preferably for then starting an internal combustion engine formed as a gas engine or as a dual fuel engine

摘要

PROBLEM TO BE SOLVED: To provide a method of start preparation of gas/two-fuel internal combustion engine.SOLUTION: An engine (10) includes groups (11) of cylinders (12) to which a gaseous fuel can be supplied through a fuel supply line (13) from which fuel supply lines (14) communicated to the cylinders (12) of each group (11) are branched. In this method, the line (13) filled with the air discharged by the gaseous fuel, is filled with the gaseous fuel by opening a fuel supply valve (15) first, and whether a pressure in the fuel supply line (13) exists in a specified pressure range over a specified time or not after closing the fuel supply valve (15), is monitored during the process in a step a). When the existence of the pressure within the specified pressure range over the specified time interval is confirmed in the step a), the gaseous fuel is equally distributed to the line (13) in a step b) by opening and closing a fuel supply valve (16) assigned to the final cylinder (12) or each of the lines (14) of the group (11) in a gas flowing direction.SELECTED DRAWING: Figure 1
