Abstract:
A method for operating an ATAC engine, wherein there is a piston which is movable in a cylinder to an upper dead center point of the piston and is movable down from the upper dead center point, the method comprising the steps of:moving the piston through the cylinder in a plurality of piston strokes, including a compression stroke to the upper dead center point of the piston; allowing the fuel to self-ignite after the compression stroke; thereafter moving the piston through a down stroke caused by the ignition; thereafter moving the piston through an exhaust stroke to the upper dead center point of the piston; thereafter moving the piston through an intake stroke, the exhaust stroke and the intake stroke together constituting a gas exchange stroke; and inserting air and injecting substantially all the fuel into the cylinder in the region of the upper dead center point of the piston during the gas exchange stroke to mix the fuel with the air.
