The article presents the impact of hydrocarbon
fuel angle of injection on heat emission characteristics in a
compression – ignition AD3.152 engine. The angle of injection
has a significant impact on the primary engine operating
parameters and combustion process indicators, which include
the proportion of combustion which occurs according to kinetic
and diffusion models, heat emission rate and the combustion
process duration. The characteristics describing emission of a
relative heat quantity were determined on the basis of an
analysis of actual, indicator diagrams averaged over 100 runs,
under the assumption that the combustion process ends by the
time the exhaust valve opens. During the test, the engine
operated according to an external speed characteristic. Tests
were carried out for three fuel angles of injection: 13, 17 and 21
crankshaft rotation degrees.
