方案详情

A combination of imaging techniques for investigations
of highly transient processes and cyclic variations in internal
combustion engines is presented. The single highspeed
camera setup uses a CMOS camera combined
with a two-stage image-intensifier and two excimer lasers.
Fuel mixing, ignition and combustion were monitored
via planar laser induced fluorescence imaging of
toluene as a tracer that was added to iso-octane in combination
with the simultaneous recording of light emission
from the spark plasma and OH* chemiluminescence
of the developing flame. Image frame rates of 12 kHz for
hundreds of cycles were achieved. Application to misfire
events in a spray-guided gasoline direct-injection engine
is described to illustrate the merits of the technique.
