<p>In a method of regulating the supply of drivingmedium per stroke cycle to a pile-driving rammer the driving-medium supply per stroke cycle is adjusted for driving piles into the ground in the shortest time in dependence upon the value, measured by at least one scanner, of the result of the least two preceding strokes of the rammer and more in accordance with the driving-medium supply adjusted during the stroke which gave the better result. In order to improve the energy transfer from a diesel hammer upon the pile apart from a basic fuel per combustion cycle at least one substance affecting the combustion velocity is supplied to the Diesel hammer in accordance with the pile-driving operation.</p> |
