FIELD: engines and pumps.
SUBSTANCE: air-hybrid engine 10 with splitted cycle comprises rotary crankshaft 16. Compression piston 20 is fitted in compression cylinder 12 to slide therein and is coupled with crankshaft 16. Compression piston 30 is fitted in compression cylinder 14 to slide therein and is coupled with crankshaft 16. Adapter channel 22 communicates compression and expansion channels 12 and 14. Adapter channel 22 comprises adapter compression valve 24 (XovrC valve) and adapter expansion valve 26 (XovrE valve) to make a pressure chamber. Air vessel 40 is communicated with adapter channel 22. Air vessel valve 44 communicates adapter channel 22 with air vessel 40. Air vessel valve 42 is located in vessel channel 44. Said channel 44 comprises first section 46 located between adapter channel 22 and valve 42. Said first section 46 features volume smaller that that of adapter channel 22 or equal thereto.
EFFECT: higher efficiency.
