Experimental Setup Of A Rapid Compression Machine For Spark Ignition Studies, Daniel Llaguno
Experimental Setup Of A Rapid Compression Machine For Spark Ignition Studies, Daniel Llaguno
Electronic Theses and Dissertations
The main objective of this thesis is to document the design and development of a rapid compression machine (RCM). A series of tests were performed to verify the operation of the system using the compression of air. Finally, an experiment was conducted to validate the auto-ignition temperature of DME under HCCI mode. Based on the first version of the RCM, improvements were made to speed up the compression process, and to create the conditions required for the auto-ignition of a DME-air mixture. The inlet diameter of the pneumatic actuation cylinder was increased to reduce the choking effect of the air …
Analysis Of Combustion In Plasma Electrolytic Oxidation (Peo) Coatings Of The Piston Surface In Spark Ignition Engines, Brendon Bain
Analysis Of Combustion In Plasma Electrolytic Oxidation (Peo) Coatings Of The Piston Surface In Spark Ignition Engines, Brendon Bain
Electronic Theses and Dissertations
With the global effort to “green” the transportation industry, the internal combustion engine (ICE) is required to reduce its carbon footprint and can do so by increasing efficiency. Plasma Electrolytic Oxidation (PEO) coatings confer properties of high wear and corrosion resistance, high hardness, excellent adhesion and a superior thermal barrier to their substrate, suggesting that coating of ICE components has the potential to greatly improve the combustion efficiency. The primary objective of this thesis is to analyze the effects of PEO coating on the surface of pistons in a spark ignition ICE, with the goal of increasing efficiency, to address …
