Transit Mixer with two engine ( front + rear ) and one fuel tank

Calculations for Transit mixer fuel average:

There are number of equipment available at project sites, garages, commercially use and domestic use. Machine owner all the time think about the savings, less expenditures, making more use of their asset. They all the time think about the performance of the asset. They allot a person to maintain their asset in good working condition. Lots of factors they consider while evaluation the working of the asset i.e. machine’s working hours, it’s preventing maintenance interval, running repair scheduling, overall operational and maintenance cost. They know that they can operate their equipment in better condition so that they can earn more and let their business move towards the profitable height.
Here I am discussing about the fuel average of the machine. A common small scale asset honor generally calculate their asset fuel consumption after the project ending or while final billing of the work. Then they realize that the actual consumption in the operation of the machine.

Here I am giving you the best way to find out or to calculate the fuel average of the transit mixer by your own.
You just have some parameters to not down. Which are as below:
1.        Total HSD filled: Every time you have to fill the tank with full of its volume and not down the total filled HSD (High Speed Diesel) quantity in liters.
2.        Note down the ODO meter reading (kilometer/ hour reading) on which fuel (diesel) filled.
3.        Also note down the meter reading of the rear engine (mixer hour meter reading).
4.        Now first assume the standard average of one engine and fix it. E.g. generally rear engine of the mixer is of four cylinder air / oil cooled, so assume it’s fuel average is of 04LPH (i.e 04 liter per hour).
5.        Now calculation for rear fuel consumed quantity:
Q (R) = A (R) x HMR (R)
                Where     Q (R)       = Fuel quantity in liters
                                A (R)         = Fuel average of rear engine
                                HMR (R) = Hour meter reading of rear engine

6.        Now you get the value of the fuel quantity consumed in rear engine.
7.        Next deduct the calculated rear fuel consumption quantity from the total filled fuel quantity Q(T).
8.        This will give you the balance quantity i.e Q (F), left for front engine.
Q (F) = Q (T) – Q (R)
9.        Now we have to find out the fuel consumption in front engine.
10.     For this divide kilometer reading by quantity of fuel balance for front engine  or divide the balance fuel quantity by the front engine working hour or.
A (F) = KMR / Q (F) , or A (F) = Q (F) / HMR
11.     This is the value you want to find out. It’s the actual fuel average of your transit mixer.
12.     By analyzing this we can find out our transit mixer performance and make it relevant to our work and increase our profit as well.


Alternatively we can analyze the calculation in the following way:

Conclusion:

If you filled the fuel of 150.0 L and 
fornt engine means Transit mixer chassis moved to 250.0 Km 
rear mixer worked for 10.0 Hr 
then the fuel average of the chassis will be 2.5 Kmpl


The result will be:

Front engine fuel average = 2.5Kmpl
Rear engine fuel average = 5LPH
