Some Effects of Fuel Structure, Tetraethyl Lead, and Engine Deposits On Precombustion Reactions in a Firing Engine

Abstract

<div class="section abstract"><div class="htmlview paragraph">THIS paper presents the latest findings in a 30-year study by GMC Research Laboratories, seeking the cause and prevention of knock in automotive and aircraft engines. The authors made a series of single-cylinder engine studies in which engine firing conditions were directly observed and recorded on supersensitive instruments through a transparent quartz window in the engine cylinder head. This enabled them to duplicate in the laboratory certain conditions in highway driving.</div><div class="htmlview paragraph">They also secured visible confirmation of how various fuels and fuel blends behave in the critical precombustion process, during the phase when the fuel’s antiknock quality is put to test.</div></div>
