Description

Technical Field

[0001] The utility model relates to the technical field of crankcases, in particular to a crankcase for a cetane number measuring machine. Background Art

[0002] The cetane number of diesel is an indicator of the combustibility of diesel. It refers to the volume percentage of n-cetane contained in a standard fuel with the same self-ignition property as diesel. Diesel with a high cetane number is easy to start, burns evenly, and has a large output power. A low cetane number means slow combustion, unstable operation, and easy detonation, which causes great damage to the vehicle. A cetane number measuring machine is a machine that measures the cetane number in diesel. The crankcase is a part of the machine. Sufficient lubricating oil needs to be added to the crankcase during operation. The lubricating oil inlet of a traditional crankcase is fixed to the crankcase. Due to the limited volume of the crankcase used for the measuring machine, the diameter of the oil inlet is small, and the gap between most oil inlets and the cylinder block arranged on the crankcase is limited. The overly compact space makes it difficult to add lubricating oil. Utility Model Content
