The invention relates to method for operation and design of combustion engine (CE). In each of working cylinders 25 at first stroke one performs intake of air or fuel-air mix, at second stroke – compression of content of working cylinders and injection of fuel or ignition, at third stroke – combustion stroke. CE is additionally equipped with compressor 5, and power cylinder – with high pressure air valve 12 and supercharge valve 13. At fourth strike worked out gasses are displaced to atmosphere. At fifth stroke the power cylinder is filled from compressor with high pressure air at value Pc = Рах (N+n), where N – ratio of calculated pressure in combustion chamber at the end of compression stroke to value of atmospheric pressure Pa; n – ratio of value of maximal calculated feeding air pressure upstream of inlet valve of working cylinder to value of atmospheric pressure, this is taken within 2 and 5. At sixth stroke injection valve is opened and with displacement of piston air with power cylinder at pressure (Рах n) is pumped to inlet section of feeding air 21. At first stroke at intake to power cylinder one uses air from inlet section of feeding air that is supplied there at sixth stroke of previous cycle. |
