|
 | An experimental study was conducted using the dumping technique (total cylinder sampling) to produce cylinder mass-averaged nitric oxide histories. Data were taken using a four stroke diesel research engine employing a quiescent chamber, high pressure direct ijection fuel system, and simulated turbocharging. Two fuels were used to determine fuel cetane number effects. Two loads were run, one at an equivalence ratio of 0.5 and the other at a ratio of ... |

|
 | The work presented was performed to increase the understanding of the important variables involved in the radial penetration of the droplet cloud formed by a liquid jet impinging on a target placed a short distance from the injector orifice. The experiments studied a spray produced in a high pressure, ambient temperature bomb by a Lucas OAV injector system with a Bosch pump. Three experimental procedures were performed. The first experiment ... |

|
| A new method has been developed for measuring the oil films on cylinder walls in engines that offers benefits in improved understanding of oil transport and consumption. The unique aspect of this work is that fiber optics and laser induced fluorescence are combined to measure the oil film thickness. As a result the system is much less intrusive than previous methods using windows to observe the fluorescence. Static tests were ... |

|
| This final report covers a broad range of research activities, each of which contributes to the improved application of zero-dimensional engine cycle codes and/or multidimensional computational fluid mechanics (CFM) codes to engine design. Most of the work focused on problems related to in-cylinder heat transfer. |

|
| A new instrument for measurement of diesel in-cylinder radiation heat transfer has been designed, calibrated, and tested in a single cylinder, open chamber, turbocharged diesel engine. The unique feature of the instrument is that it measures the total radiation flux over the entire hemisphere, rather than being restricted to a finite acceptance angle of less than 2 P steradians as have previous instruments. The paper gives the instrument design details ... |

| Results of four research projects each dealing with instantaneous heat flux to the cylinder head of reciprocating engine are given. The projects are: heat flux to the cylinder head of a reciprocating engine are given. The projects are: heat flux measurements in a diesel engine with variations in injection pressure, nozzle tips and swirl; development of instrumentation for radiation measurements in a diesel cylinder; heat flux measurements to various surfaces ... |
