Abstract
A combustion power tool having a first combustion chamber, a second combustion chamber, an igniter, a partition, and a driving mechanism. Flammable gas is introduced or charged into the first and second combustion chamber. The igniter is disposed in the first combustion chamber. The partition separates the first combustion chamber from the second combustion chamber. Communication holes are formed in the partition at different angles with respect to the longitudinal direction of the first combustion chamber. The communication holes communicate the first combustion chamber with the second combustion chamber. The driving mechanism performs a predetermined processing work by utilizing an explosive combustion pressure. The combustion pressure is generated when flammable gas in the first combustion chamber is explosively burned by the igniter and when the burning front of the flammable gas in the first combustion chamber propagates to the second combustion chamber via the communication holes of the partition thereby explosively burning flammable gas in the second combustion chamber.
