METHOD FOR OPERATION OF A FREE PISTON ENGINE

摘要

Method for operating a free-piston engine (10) to produce relatively low amounts of undesirable NOx by initiating injection of the atomized fuel mixture into the combustion chamber after closure of exhaust apertures (28) by the combustion chamber piston during the compression stroke thereof to attain a homogeneous fuel-air mixture and relatively lower and more uniform local combustion flame temperature in the combustion chamber.
