ABSTRACT:
Improvements to diesel power hammers which allow the hammers to be operated smokelessly are disclosed. Kerosene and synthetic oil replace diesel fuel and mineral oil as fuel and lubricant, respectively, in hammers incorporating prior art design improvements by Makers thereof. Other combustibles such as gasoline may be added to the kerosene fuel to improve the quality of combustion and thereby further reduce the emission of smoke.
