FIELD: internal combustion engine applications.
SUBSTANCE: invention relates to manual hammering tools actuated by fuel-fed engines. Fuel gas contains at least 40% α-butylene, propane or propylene. Tool is intended for hammering fixing parts and comprises body, top part constructed with passage for fuel gas, and cylinder secured inside the body. When pressed to a part to be processed, pusher moves. Casing of combustion chamber forms the same along with top part of the body and piston. compressed gas container for tool comprises external and internal balloons, fuel gas injection valve, and dispensing mechanism. Fuel gas may contain various percentages of α-butylene.
EFFECT: reduced cost of running tool due to use of inexpensive fuel.
