Specific Heat Capacity Question watch

1. I think I am missing some things for this to work. This is what I've been given.

The context is diesel inside an internal combustion engine.

The amount of diesel fuel is 500 litres.

The specific heat capacity is given as 2200 per kg.kelvin
The calorific value of the fuel is 42.58 X 10^6 J per kg
The density of the fuel is 0.84 per litre

Of course, simply using Q=mc( Change in Temp) and rearranging for (change in temp) is not enough. If it is done, it gives a funny large amount in terms of temperature. I'm assuming the calorific fuel is the amount of energy available

It's been some time since I did A level physics but I'm sure Specific Latent heat of vaporisation would be used too?

How do I incorporate the two? Also, just gut feeling, but I would also have to convert some of the above units as well right? Thanks in advance
