Bike with 24 chainsaws as engine
A motorcycle powered by 24 chainsaws.
Takes them a while to start it up, though.
Test run
The making of....
The site
Those european are da*n crazy..... First scooter with GiXXeR engine, now chainsaw. What's next??
The engine
What makes the Dolmette unique in engineering terms is its 24-cylinder 2-stroke power plant. Nothing quite like it has been seen before. The combined power of 24 DOLMAR chainsaw engines is fed into to a 5-speed Harley-Davidson transmission by a series of twelve toothed belts.
The engine in question is the one used in the PS-7900 professional chainsaw, which currently boasts the best power-to-weight ratio of any professional petrol chainsaw in the world – just 1 kg per PS. In standard trim each of these high-performance air-cooled 79 cc units generates 4.6 kW of power (6.3 PS) at 9500 rpm. A specific output of 59 kW per litre is outstanding for a chainsaw, and the secret lies in DOLMAR’s High Performance Combustion (HPC) technology. This term refers to the special design of the six gas exchange ports in combination with the asymmetrical combustion chamber head and the crankcase configuration: the result is a highly efficient combustion cycle with low exhaust emissions.
