It means the engine cubic capacity is 3.5 litres and it is a compression ignition engine that runs on diesel fuel.
A cubic foot is a cubic foot is a cubic foot... If you are referring to ask for a given equal mass of water and diesel fuel: The specific gravity of #2 diesel fuel is about 0.89, depending on the quality. The specific gravity of a liquid is the ratio of it's density to that of water. Since the specific gravity of diesel is less than one, it is less dense than water. Conversely, diesel is more voluminous than water. It will float on top of it. The answer to this question is that for an equal mass of water and diesel the latter will occupy more volume.
Of diesel fuel?
Two litres of fuel will fit in a container 10cm x 10cm x 20cm.A cubic meter of liquid is 1000 liters, plus you need expansion space...a 2200-liter tank would hold it, but 2500 liters is a standard size so get that one.
There are 1000 kilograms (kg) in a metric ton (or tonne). And there are about 0.264 gallons in a litre. Also, the density of diesel fuel is right at about 0.85 kilograms per litre. Since you have a metric ton of diesel fuel, that is 1000 kilograms of diesel fuel, you need to know how many litres of diesel fuel you have. Divide 1000 kg by 0.85 kg/litre and you'll get about 1176.5 litres. Now convert that to gallons by multiplying 1176.5 litres by 0.264 gallons/litre and you'll get about 310.6 gallons of diesel fuel in that metric ton you started with.
