An optical investigation into the reactive fuel spray of high-pressure DME and Ethanol

Reducing harmful emissions and increasing thermal efficiency in internal combustion engines have been the foremost goals of modern engine research. Compression ignition (CI) engines offer advantages in terms of high-efficiency operation as the overall in-cylinder mixture is lean. High-pressure direct injection fueling systems, commonly employed in CI engines, allow for the precise control of the combustion through injection timing and heat …
