Тема: Knowing how much Fuel gets consumed when unit is Idle using CANBUS

Good afternoon, i have a question/problem
I have a unit with CANBUS, and i need to know how much fuel gets consumed when the unit is idle in a report (or when the unit has ignition but is not moving) but i dont know how to do it.
The GPS is a Ruptela Pro5 Lite, i have a sensor called "Combustible Utilizado" (Fuel Used) and i have it with the parameter "can_fuel_used" i have a feeling i can use this to know the data i want but i dont know how or if its a formula i need to use to get this information, or if its there other parameter form this device that can get me that information.

Thank you, any help is appreciated.

these are some parameter that the device sends me:

Re: Knowing how much Fuel gets consumed when unit is Idle using CANBUS

jornadadgps22 there is probably an ignition sensor, in that unit. Create an Absolute Fuel consumption sensor with the can_fuel_used parameter. Then add an Engine hours table, in the table add Consumed in idle run by AbsFCS column. If the can_fuel_used displays litres, then no other adjustments are required. If there is no ignition sensor available in the messages, create an Absolute engine hours sensor with the can_eng_hours parameter, and select it as a counter in the for the Engine hours in the General tab of the unit's properties. The rest is the same as for a generic ignition sensor.

Re: Knowing how much Fuel gets consumed when unit is Idle using CANBUS

Hi, thank you, excuse me i have another question.
I got in contact with support and they told me another way to get the fuel consumed in idle using CANBUS.
The method consist in using the "can_fuel_rate", selecting the "calculate fuel consumption by sensor".
Create a table with the column "Consumed by InsFCS in idle", but the problem is that the result doesnt seems right to me, like it said it consumed 107 liters in idle, but consumed in the trip was like 193l. but in total the fuel consumed was 223.50.
My question is, is there a formula or an operacion that i need to do so that it gives me a more realistic fuel consumption in idle using CANBUS???

Thank you, any help is appreciated.

Re: Knowing how much Fuel gets consumed when unit is Idle using CANBUS

jornadadgps22 the issue might be caused by the can_fuel_rate logic. Rate shows what is the speed of the consumption in a specific data message. For example:
- 10:00 can_fuel_rate=12
- 10:01 can_fuel_rate=5
- 10:02 can_fuel_rate=9
It means, that at 10:00 the fuel has been consumed with the speed of 12 let us say litres per for example hour.

Since it does not show Consumption, it can not be used for the consumption calculation. At least not straight away.
You may check this parameter yourself via the Messages tab. If the parameter equals to 0 during stops and changes during the work intervals, then it is most likely a consumption speed, not a consumption value.

If that is tru, I may recommend not wasting time with this parameter, and get back to something more relevant like can_fuel_used.
