PEM-9004 FAQ​

​

Q: ​We have a PEM 9004 and need to add another fuel to the list. However, we do not know what some of the required variables are. Can you please define what A2 and B are? 

A: The A2 and B variables are special factors of the fuel, which are demandable for the calculation of the efficiency (Eta) respectively losses (qA). These factors are to be requested from the fuel supplier. 

About that please refer to the fuel factor list for North American users. Maybe it could help you find out the right factor values of the A2 and B.​
