Thermal Management Coatings for High Performance Diesel Engines

Several variants of thermal management coatings for high-output diesel engines were produced by an atmospheric plasma spray process. A large database of thermal and mechanical properties of these coatings was developed for materials selection. Coatings from this database were screened for potential in engine use by novel laboratory tests, deposited on piston crowns, and tested in a single Cylinder research engine. Coatings appear very durable, even under the highest load conditions tested, while limited direct benefits to thermodynamic efficiency were observed. Potential strategies to use coatings to enable systemic benefits are briefly explored and are elaborated 0 11 in this works follow-up proposal.
