"two-start" internal combustion engine with preliminary cooled compression

FIELD: engines and pumps. SUBSTANCE: invention relates to two-stroke internal combustion engines with a split cycle. Principle of the invention consists in that the engine has a single or multi-stage pre-cooled compression, which allows the temperature and pressure of the air sucked into the combustion cylinders to be under full control, and due to that a much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the autoignition threshold. Since this design can effectively regulate and set the maximum pre-ignition temperature of the air-fuel mixture, it can work on virtually any type of liquid hydrocarbon fuel without knocking. Due to its higher compression ratio, this "push-pull" motor generates energy equal to or greater than the four-stroke CWPSC engine in a lighter and smaller casing and with equal or greater efficiency. EFFECT: technical result consists in higher engine efficiency. 6 cl, 4 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 645 888 C1 (51) МПК F02B 29/04 (2006.01) F02B 33/16 (2006.01) F02D 23/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК F02B 29/0493 (2017.08); F02B 33/16 (2017.08); F02D 23/00 (2017.08) (21)(22) Заявка: 2016138796, 26.02.2015 (24) Дата начала отсчета срока действия патента: (73) Патентообладатель(и): КРИСТАНИ Филип (US) Дата регистрации: 28.02.2018 R U 26.02.2015 (72) Автор(ы): КРИСТАНИ Филип (US) (56) Список документов, цитированных в отчете о поиске: US 2006124085 A1, 16.06.2006.

Internal combustion engine

FIELD: engines and pumps. SUBSTANCE: invention relates to ICE, namely to arrangement of ignition source in separate-cycle expansion cylinder. ICE comprises crankshaft 52, cylinder head 70, compression and expansion cylinders 66 and 68, respectively, compression piston 72 and expansion piston 74, bypass channel 78 and ignition source 104.Compression piston 72 reciprocates to intake and compress in revolution of crankshaft 52. Expansion piston 74 reciprocates to expand and discharge in revolution of crankshaft 52. Bypass channel 78 communicates said compression and expansion cylinders. Bypass channel incorporates bypass valve 84 and expansion bypass valve 86 with high-pressure chamber arranged there between. Central section 106 of ignition source 104 is located at a distance from closest peripheral edge 110 of expansion bypass valve passage 98 that equals or exceeds safe distance S. Said safe distance S prevents ingress of burning gas into said passage 98 unless it is shut off for, at least, portion of ICE operating rpm. Said safe distance S is defined by expression: S [mm] = combustion rate [mm/degree of crankshaft turn] x crankshaft turn angle between ignition and expansion bypass valve closure [degrees]. EFFECT: longer life of expansion valve, optimum relation between complete combustion and detonation prevention. 13 cl, 7 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 430 246 (13) C1 (51) МПК F02B 33/02 (2006.01) H01T 13/08 (2006.01) F02B 41/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2010101849/06, 11.06.2008 (24) Дата начала отсчета срока действия патента: 11.06.2008 (72) Автор(ы): ПИРО Жан-пьер (GB), ГИЛБЕРТ Ян П.

Engine with split cycle and method for its operation

FIELD: engines and pumps. SUBSTANCE: internal combustion engine (ICE) with split cycle includes crankshaft (52), compression (66) and expansion (68) cylinders, compression (72) and expansion (74) pistons, and bypass channel (38). Compression piston (72) performs inlet and compression strokes per one turn of crankshaft (52). Expansion piston (74) performs expansion and outlet strokes per one turn of crankshaft (52). Bypass channel (38) connects compression (66) and expansion (68) cylinders. Bypass channel (38) includes bypass compression valves (BCV (84)) and bypass expansion valves (BEV (86)). High pressure cavity is made between bypass valves (84, 86). BCV (84) opens when pressure in compression cylinder (66) is lower than pressure in initial part of bypass valve (78) near bypass compression valve (84). Also, the invention describes operating method of ICE with split cycle, in which BCV opens when pressure in compression cylinder is lower than pressure in initial part of bypass valve, near bypass compression valve. EFFECT: increasing the opening time of valves and reducing the power consumed on delivery in engines with split cycle. 16 cl, 13 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 435 046 (13) C2 (51) МПК F02B 41/00 F02B 33/22 F02B 33/44 (2006.01) (2006.01) (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2010101967/06, 11.06.2008 (24) Дата начала отсчета срока действия патента: 11.06.2008 (73) Патентообладатель(и): СКАДЕРИ ГРУП, ЭлЭлСи (US) R U Приоритет(ы): (30) Конвенционный приоритет: 07.08.2007 US 60/963,742 (72) Автор(ы): ФИЛЛИПС Форд А.
