IT CAN BE CALCULATED THEORETICALLY & PRACTICALLY:-
1. theoretically---
For this you must know the SFC(specific fuel consumption) of the engine at the given load.
for example(let us consider a diesel generator of 20 kw having SFC as 232 gm/kw-hr at 75% load)
(20x0.75)x232
therefore Fuel consumption in ltrs/hr= =4.094ltr/hr
0.85x1000
here 0.75 is for 75% load
0.85 is density of diesel
1000 is factor to convert milli-litre into litres
consumtpn
You can calculate fuel consumption per Kilowatt hour in diesel engine by multiplying the miles per gallon by the wattage per hour that the engine runs. This gives the net Kilowatt hour fuel consumption.
The consumption of lubricating oil for a diesel engine depends on the operating conditions and the design of the engine. There are some averages depending on the year of the engine. Pre 1980's engine are around 25% of fuel consumption. Pre 1990 engines are around 20% of fuel consumption and more recently built diesel engines are around 1% of fuel consumption.
1hrs diesel consumption with out load
is the fuel consume by the the engine
Diesel Engine SFC is Specific Fuel Consumption of Diesel Engine. This used to know how efficient Fuel utilization of Diesel Engine to produce electricity. Usually formula of SFC is Fuel Consumption divided by Electricity Production (liter/kWh).
There are several causes for high fuel consumption in a diesel engine. These include a difference in the weight of the vehicle, increased usage of air conditioning, and a difference in tire pressure.
Depends entirely on the load being applied to the engine.
You'd be lucky to get 30mpg tops
only if it has a diesel engine. A gasoline engine will not run properly on diesel fuel.
Diesel engines run on diesel fuel. Gasoline will destroy a diesel engine.
If the van has a diesel engine, then you MUST use diesel fuel. Unleaded gasoline will destroy a diesel engine. Diesel fuel is also used as a lubricant in a diesel engine. The use of any other fuel except diesel will result in serious damage. If you have put unleaded in your diesel, do not start or drive this vehicle until you drain the tank and change all the fuel filters.If the van has a diesel engine, then you MUST use diesel fuel.
