Because the diesel cetane number machines based on the standard method are all dependent on imports and are expensive, which affects the strict implementation of domestic diesel quality standards, the localization of this instrument is of great significance. On the basis of years of research and development of bench testing machines, the diesel cetane number machine has been successfully developed in strict accordance with ASTM D613 and GB/T 386-2010 standards. Independent intellectual property rights. The main body is a standard single-cylinder, four-stroke, variable compression ratio, indirect injection diesel engine. Under the conditions of controlling the fuel flow, injection time and compression ratio, the diesel engine to be tested is compared with the standard fuel to obtain a diesel engine. A measure of the ignition lag period.
The stability and reliability of the instrument, the accuracy and stability of the results can reach the level of similar imported products, and at the same time, the automation level of the test operation is improved to the greatest extent, so that the cetane number test of the diesel engine is no longer cumbersome.
