- Abstract
- In the present paper, infrared (IR) measurements were
performed in order to study the development of injection and
combustion in a transparent Euro 5 diesel engine operating in
premixed mode. An elongated single cylinder engine
equipped with the multi-cylinder head of commercial
passenger car and with common rail (CR) injection system,
respectively, was used. A sapphire window was set in the
bottom of the combustion chamber, and a sapphire ring was
placed between the head and the top of the cylinder line.
Measurements were carried out through both accesses by a
new high-speed infrared (IR) digital imaging system
obtaining information that was difficult to achieve by the
conventional UV- visible camera. IR camera was able to
detect the emitted light in the wavelength range 1.5-5 ìm that
is relevant for the emission bands of CO2 and H2O. The
evaporation phase of pre and main injection, and subsequent
combustion evolution were analyzed. Moreover, IR imaging
was carried out by means of ad hoc filter to evaluate the
spatial distribution of CO2 inside the cylinder. Images
sequence during the whole engine cycle, starting from the
intake and stopping to the exhaust phase, was observed from
both optical windows. A comparison with visible imaging
was carried out. IR measurements showed the ability to
determine temporal and spatial distribution of fuel during
evaporation phase and evaluate the combustion process
evolution for longer time than visible imaging. Moreover, the
IR camera was revealed very useful tool to detect the emitted
light after a long operation time of the engine. The camera
was able to acquire images of the reactions that happen in the
combustion chamber and above the piston head even if the
optical windows were obscured by the soot produced from
the previous combustion cycles. (literal)
