Abstract

A hydrogen internal combustion engine (10) comprising a cylinder (12) having a chamber (12A), a piston (14) configured to reciprocally travel in the chamber (12A), an intake port (32) configured to conduct intake gaz within the chamber (12A), an exhaust port (34) configured to discharge combusted gaz outside the chamber (12A), and an active vacuum system (40) configured to depressurize the chamber (12A) via a vacuum port (36), the vacuum port (36) being distinct from the exhaust port (34).

IPC Classes  ?

• F02B 75/02 - Engines characterised by their cycles, e.g. six-stroke
• F02B 35/00 - Engines characterised by provision of pumps for sucking combustion residues from cylinders
• F02B 43/10 - Engines or plants characterised by use of other specific gases, e.g. acetylene, oxyhydrogen

Abstract

A hydrogen internal combustion engine (10) comprising a cylinder (12) having a chamber (12A) extending along an axis (Y1), a cylinder head (54), a movable jacket (60) configured to reciprocally travel in the chamber (12A), a piston (14) configured to reciprocally travel in the movable jacket (60), an intake port (32) arranged in a side wall of the cylinder (12), an exhaust port (34) arranged in a side wall of the cylinder (12), the movable jacket (60) having an intake through hole (60A) and an exhaust through hole (60B) respectively configured to allow fluid communication between the intake port (32) / exhaust port (34) and the chamber (12A) depending on the relative position of the movable jacket (60) relative to the cylinder (12), and a fuel injection port (38) arranged in a wall of the cylinder head (54).

IPC Classes  ?

• F02B 21/00 - Engines characterised by air-storage chambers
• F01B 9/02 - Reciprocating-piston machines or engines characterised by connections between pistons and main shafts, not specific to groups with crankshaft

• F02B 25/28 - Multi-cylinder engines other than those provided for in, or of interest apart from, groups with V-, fan-, or star-arrangement of cylinders
• F02B 75/04 - Engines with variable distances between pistons at top dead-centre positions and cylinder heads
• F02B 75/22 - Multi-cylinder engines with cylinders in V-, fan-, or star-arrangement
• F02M 21/02 - Apparatus for supplying engines with non-liquid fuels, e.g. gaseous fuels stored in liquid form for gaseous fuels
• F02B 75/02 - Engines characterised by their cycles, e.g. six-stroke
• F02B 43/10 - Engines or plants characterised by use of other specific gases, e.g. acetylene, oxyhydrogen
