SDB-600T Automatic Cetane Rating Unit Engine

Description

Standards
GB/T 386，ASTM D613

Application
This instrument meets ASTM D613 and ISO 5165 completely. Its functional performances can meet or be better than the standard requirements with independent and intelligent properties. The main unit of is a standard single cylinder, four stroke, variable compression ratio, indirect injection diesel engine. The diesel fuel oil can be tested under the condition of controlling the fuel flow rate, the fuel injection time and thecompression ratio, and compared with the standard fuel to measure the ignitiondelay timing.
