An Investigation Into OME3 on a High Compression Ratio Engine
ASME 2020 Internal Combustion Engine Division Fall Technical Conference, 2020Abstract For decades, alternative fuels have been studied to further engine efficiency and lower combustion emissions. Of these fuels, biodiesel, alcohols, and ethers have shown advantageous benefits of improved mixing capability or reduced combustion emissions.

Energy Optimizing of High-Compression-Ratio Combustion Chambers
SAE Technical Paper Series, 1984<div class="htmlview paragraph">A synthesis of the research undertaken at the Institut Francais du Pétrole to understand phenomena of combustion, of heat transfers, and of knock and controlling to optimize high-compression-ratio combustion chambers has led to the proposing of two specific research topics: - calm chamber with dual ignition ...

Investigating Pre-Mixed Charge Compression Ignition Combustion in a High Compression Ratio Engine
SAE Technical Paper Series, 2018<div class="section abstract"><div class="htmlview paragraph">Utilizing a higher compression ratio in a Compression Ignition (CI) engine grants an obvious advantage of improved thermal efficiency. However, the resulting combustion temperatures promote dissociation ensuing in increased nitrogen oxide (NO<sub>x</sub>) emissions ...

A NONUNIFORM HIGH-QUALITY IMAGE COMPRESSION METHOD TO PRESERVE USER-SPECIFIED COMPRESSION RATIO
International Journal of Image and Graphics, 2011Most of image compression methods are based on frequency domain transforms that are followed by a quantization and rounding approach to discard some coefficients. It is obvious that the quality of compressed images highly depends on the manner of discarding these coefficients.

High compression ratio backward Raman conversion for high brightness excimer laser systems
IEEE Journal of Quantum Electronics, 1993A scheme of backward Raman pulse compression is proposed in which the backward first Stokes pulse is amplified under stationary conditions and the backward second Stokes under transient conditions by choosing an appropriate Raman medium. The compression factor and efficiency are improved by insertion of selective absorbers for the second Stokes ...

Study on the gridded electron gun with high compression ratio
2002 3rd International Conference on Microwave and Millimeter Wave Technology, 2002. Proceedings. ICMMT 2002., 2003The electron gun structure sizes were obtained with a fast calculation method. An electron gun with a perveance of p/sub /spl mu//>1 /spl mu/p and the area compression ratio M/sup 2/ > 50 was designed with the GUND4.FOR program.

Optimum Compression Ratios for a High-Speed Diesel Engine
Journal of Fluids Engineering, 1945Abstract Optimum compression ratios must give smooth and reliable ignition. They are high enough to procure maximum fuel economy. They are determined from data presented to show the effect of compression ratio upon the combustion and performance characteristics of a high-speed (2000-rpm) 3.25 × 4.5-in.
