Common Problems and Solutions of ASTM-CFR Octane Number Machine
摘要
Abstract
The antiknock property is the most important test item of automobile fuels such as automobile gasoline and automobile ethanol gasoline,and is an important index to measure the quality and performance of oil products.According to the test methods stipulated in GB/T 5487-2015,Determination of the gasoline octane number—Test method for research octane number,and GB/T 503-2016,Determination of the gasoline octane number—Test method for octane number,the test equipment must choose octane number rating machines to test related items.The paper takes Waukesha's ASTM-CFR octane number testing machine manufactured in the United States as an example.Five main problems during the operation of this kind of testing machines are expounded,which include unstable detonation meter reading,intake air temperature falling to be raised in the normal time of the instrument,unfitting gaps of intake valves and exhaust valves,too low circulating cooling water level,and too little hot oil.Also,the solutions are put forward,which help gasoline testing personnel to quickly solve the problems during the experiment,and improve the detection accuracy of antiknock index of gasoline products.关键词
