Piston engine cylinder head - feeds fuel and superheated steam into pre-compressed combustion air

摘要

The piston engine cylinder head has an inlet valve feeding combustion air and fuel, and an exhaust valve. Additionally, an injection valve (9) is provided for input of superheated steam into the cylinder space (4), and opens shortly prior to commencement of combustion in the cylinder space (4) for input of a predetermined amt. of steam. A steam pipe (12) for superheated steam connects to the injection valve (9), and issues steam at a pressure which is double the highest pressure occurring during compression in the cylinder space. The valve axis (18) of the injection valve and the cylinder axis (17) of the cylinder head (1) run parallel to each other, the injection valve being arranged centrally in the cylinder head. USE/ADVANTAGE - To reduce the noxious nitrous oxide content in combustion gas in a piston engine.
