Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research program was to investigate, develop, and demonstrate thermal energy storage systems for the improvement of the starting characteristics of Army Diesel engines exposed to cold temperatures overnight. Because of the effect of the oil temperatures on starting work, a passive thermal protection system that used Phase Change Materials (PCM) and insulation was designed for the oil pan and filter. Waste heat was stored in the PCM during engine operation, and was released back into the oil system after engine shutdown. Experimental tests were conducted with the PCM applied to the oil pan and filter of an M925 5-ton truck. After engine shut-off the oil temperature at the bottom of the pan was maintained at +50 deg F during a 12 hr exposure to average air temperature of 13 deg F. During cold start tests conducted after overnight cold exposure, the engine with the PCM applied to the oil system started faster and required much less cranking energy from the batteries than the baseline engine under similar conditions. A secondary benefit of the warmer oil is the improved engine lubrication at startup, which can reduce engine wear. A passive thermal protection system was also built and tested for the battery box.

This book was released on 2015 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel engine performance during cold starting is very crucial for smooth engine start at undesirable emission level. The development of cold start strategies that improve combustion stability relies mainly on the understanding of the combustion process during the cold starting. Even for modern diesel engines, the conditions during the cold start is far from normal operation characterized by large amount of unburned hydrocarbon emissions and long start to idling time. Thus, the use of an in-cylinder combustion sensor to measure the combustion quality during engine starting can significantly improve engine cold start control strategies. The ion current sensor has the potential to be used as onboard sensor to measure the combustion process during engine operation and can be used as feedback to the engine control unit. The aim of this research is to study and determine the combustion instability and its impact on various combustion and ionization characteristics by performing cycle analysis for a comparison between engine performance using ultra low sulfur diesel (ULSD) and aviation jet propulsion (JP8) fuels during cold start at 25 degrees Celsius. It also shows a comparison between two ion current sensors during low load idling using the same fuels. For this purpose, the glow plug and fuel injector of VW 2.0L turbocharged diesel engine were modified and electrically insulated to be used as ion current sensors. The experimental test was conducted to study the combustion process and emission product produced during low load idling.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental and numerical study was carried out to simulate the diesel spray breakup, vaporization, ignition, and combustion during cold starting conditions. This report summarizes the optical diagnostics and multi-dimensional computation results for two single-cylinder optically accessible engines. The results showed that optically accessible engines provide very useful information for studying the diesel cold starting conditions, which also provide a critical test for diesel combustion models. The pre-ignition chemistry showed great sensitivity to the compressed air temperature. KIVA with a modified shell model responds accordingly to the change of inlet air temperatures and fuel injection parameters. However, other submodels do not have enough sensitivity to simulate the starting of diesel engine without careful validation and further improvements. A method to compute the ignition delay in engines from data obtained in constant volume vessels was also developed. The method accounts for the effect of variations in charge pressure and temperature on the formation of the chain carriers from the combustible mixture during the ID period. A comparison is made between the computed ID and data obtained in a LABECO research engine under different ambient temperatures ranging from +200 to - 100 C.

Available in PDF, EPUB and Kindle. Book excerpt: This report includes the results of an investigation on the autoignition and combustion processes in diesel engines at low ambient temperatures. Experiments were conducted on three different single-cylinder direct-injection, four-stroke engines, using fuels of different cetane numbers and physical properties. Tests covered ambient temperatures ranging from 250C to -250C. The engines were soaked at least eight hours before a cold start test. The analysis indicated that the difficulty in starting diesel engines is caused by combustion instability at low temperatures. Combustion instability will cause the engine to misfire once before it fires again. This is referred to as 8-stroke-cycle operation. If it misfires twice, it is referred to as l2-stroke-cycle operation, and so on. This pattern was found to be reproducable. The engine may start on a l2-stroke-cycle operation at low temperatures, shift to an 8-stroke-cycle, and finally shifts to the regular 4-stroke-cycle. This pattern has been found not to be engine or fuel specific. A detailed thermodynamic and combustion analysis of the experimental data indicated that the cause for combustion instability is a combination of dynamic, physical and chemical kinetics factors. Recommendations are made to reduce combustion instability by using the electronic controls already available on engines.
