Improved Method of Using Hydrogen and Ammonia Fuels for an Internal Combustion Engine
Presentation

Improved Method of Using Hydrogen and Ammonia Fuels for an Internal Combustion Engine

David ToyneJay Schmuecker

A tractor mounted internal combustion engine is fueled by Hydrogen or a combination of Hydrogen and Ammonia. Developments of an improved method of fuel injection and ignition control. Hydrogen is port injected in the intake manifold, and liquid ammonia is injected in the throttle body. A dual fuel ECU, Engine Control Unit, controls the fuel mixtures and the firing of multiple coils for ignition. The paper will address significant engine performance improvements and the resulting fuel consumption and engine emissions levels.

Advances in Making High Purity Nitrogen for Small Scale Ammonia Generation

David ToyneJay Schmuecker

The presentation will address recent developments in the Solar Hydrogen Demonstration Project in which hydrogen, nitrogen and ammonia are made from solar power, water, and air; and used to fuel a modified John Deere farm tractor. In industrial applications very pure nitrogen is made by cryogenic distillation of air. Using Pressure Swing Absorption systems alone it is extremely difficult to achieve the required purity. An improved method was developed for making high purity nitrogen, for smaller systems. Will discuss how, when Oxygen contaminates the reactor catalyst, Hydrogen is used to purge the catalyst, and subsequently used as fuel.

Our Iowa Renewable Hydrogen and Ammonia Generation System

Jay SchmueckerDavid Toyne

The presentation will summarize the development of the demonstration size renewable fuel and fertilizer system on my Iowa farm. Solar power, water, and air are used to make hydrogen and ammonia fuel used to power a modified John Deere 7810 tractor. The ammonia can also be used to fertilize corn cropland. The development of the ammonia reactor will be described and its performance discussed. There are no carbon emissions in either the generation or consumption of the hydrogen and ammonia.

Further development results of the Raphael Schmuecker Memorial Solar Hydrogen and Ammonia prototype plant, discussing making of Nitrogen and Ammonia, the energy usage, and the general system efficiencies and output. We would also like to discuss our results of dyno testing the Hydrogen / Hydrogen & Ammonia tractor engine and further developments in ammonia fuel vaporization.
