Abstract
Disclosed is a method of operating an internal combustion engine simultaneously with ammonia and another fuel. The other fuel may be hydrogen, ethanol, propane, natural gas, liquefied petroleum gas, or the like. In a preferred embodiment, the other fuel is hydrogen and the engine has zero carbon emissions. A control system is programmable to adjust the proportion of ammonia and the other, catalyst fuel as selected by the operator.
Claims7
A method of starting and operating an internal combustion engine to generate zero carbon emissions, comprising the steps of:
- (a) providing a flow of ammonia fuel from an ammonia supply tank;
- (b) heating the ammonia fuel above its ignition temperature at the start yap of the engine;
- (c) providing a flow of hydrogen fuel from a separate hydrogen supply tank;
- and
- (d) simultaneously supplying the ammonia fuel and the hydrogen fuel to the internal combustion engine;
- and
- (e) ceasing heating of the ammonia fuel when the engine temperature exceed the ignition temperature of the ammonia fuel.
