论文已在中国上海举行的第27届CIMAC大会上发表。论文的版权归CIMAC所有。Development and application of ad-nition. Pulsed laser illumination was used for visualiza-vanced engineering tools-for description, prediction of fuel jets, from which information on fuel jet pen-and optimization of the 2-stroke Diesel engine process penetration, jet velocity, and spray angles could be gathered essential for development of the marine engines. For this purpose a high-power laser and a custom of the future. Here, recent developments of optical tom designed imaging system was mounted directly and laser based imaging tools will be presented. Such onto the optical cover. The fuel jet data is qualitatively tools can lead to both increased understanding and compared to results from KIVA simulations, in order to predictive capabilities of for example the scavenging tune spray parameters in the numerical model. The process, fuel spray structure, flame ignition, and ther-same laser system was also used for measurements mal loads. For optical studies access to the combus-of in-cylinder flow velocities, in order to characterize tion chamber has been achieved using sapphire win-swirl and scavenging. Particle image velocimetry(PIV)was used for those velocity measurements. Finally, in-frared imaging was employed for two purposes, firstly for capturing the evolution of piston temperature distributions during single engine cycles and secondly for visualization of scavenging of hot product gases.
