Abstract
Described are methods for shortening the combustion delay of ammonia fuels and reducing the amount of NO formed during the combustion process. The methods include mixing ammonia with hydrogen peroxide and water to form a fuel mixture and then combusting the fuel mixture. Methods of powering an internal combustion engine with ammonia fuels are also described.
Claims13
A method for combusting ammonia, the method consisting of:
- directing ammonia, hydrogen peroxide, and water into a chamber to create a fuel mixture, wherein the amount of ammonia in the fuel mixture is 48-97% molar, and wherein the amount of hydrogen peroxide in the fuel mixture is 2% molar and wherein the amount of water in the fuel mixture is up to 50% molar, and combusting the fuel mixture with an oxidant.
A method for powering an internal combustion engine, the method consisting of:
- directing ammonia, hydrogen peroxide, and water into a combustion chamber of the internal combustion engine to create a compressed fuel mixture, wherein the combustion chamber is defined by a cylinder and a piston and wherein the amount of ammonia in the fuel mixture is 48-97% molar, the amount of hydrogen peroxide in the fuel mixture is 2% molar and wherein the amount of water in the fuel mixture is up to 50% molar, and
- combusting the compressed fuel mixture to increase a pressure in the combustion chamber and generate a force acting against the piston.
