Reducing emissions of a large bore two stroke cycle engine using a natural gas and hydrogen mixture
… combustion. Blending hydrogen into an engine's fuel can lower in-cylinder combustion temperatures and reduce pollutant emissions. Hydrogen has a wider flammability range in comparison to natural gas, which allows for leaner engine operation and lower combustion temperatures. Specifically, the …

Combustion signatures of various energetic metal powders in a shock tube experiment
Metal additives are used in explosives and solid propellants in order to increase the energetic output and effectiveness of the explosives or fuel. Aluminum has been the primary solid fuel additive to solid fuel to improve the combustive properties of propellants. Several other metals are being …

Adsorption of Model Fuel Additives at the Metal/Oil Interface
… deposits leads to diminished engine performance, fuel economy and emissions quality. The addition of deposit-control additives to fuels is thought to mitigate this issue through their interactions with the internal metal surfaces of engines. This thesis pursues a fundamental understanding of the …
