Knock-Limited Power Outputs From a CFR Engine Using Internal Coolants. III. Four Alkyl Amines, Three Alkanolamines Six Admides, and Eight Heterocyclic Compounds

摘要

An investigation of the antiknock effectiveness of various additive-water solutions when used as internal coolants has been conducted at the NACA Cleveland laboratory. Nine compounds have been previously run in a CFR engine and the results are presented. In an effort to find a good anti-knock-coolant additive with more desirable physical properties than those of the nine compounds previously investigated, water solutions of four alkyl amines, three alkanolamines, six amides, and eight heterocyclic compounds were investigated and the results are presented.
