The investigation described in this thesis is a study of instantaneous heat fluxes (total and radiative) and their variation with operating conditions in a high-swirl direct-injection diesel engine. The problem is approached experimentally and methods for prediction of convective and radiative components are suggested. Total heat fluxes were measured using a thin-film type thermocouple developed in the course of the work, while the radiant flux was measured by a pyroelectric infrared detector. The experimental observations demonstrate variations in local heat fluxes which are moderate under motored conditions but large in the fired engine. Some of the observed features of flux variation with time and with location have been shown to be qualitatively explicable in terms of probable local events during the cycle.
