Hello everyone,

I once memorized the density of diesel fuel at various temperatures; I thought it might be interesting for those '10-cent tuning' projects.

Temperature (°C) | Pressure (bar) | Density (kg/m³)

0° 900 888
10° 900 882.5
20 900 876.9
50 900 860.3
80 900 843.7
100 900 832.6

If you manipulate the engine control unit to display a diesel temperature of 100° instead of 0°, it will likely inject approximately 8% more diesel fuel.
Can we also assume that approximately 8% more power can be achieved?

I think that's being portrayed in a somewhat negative light.
2. attempt.

0° (the first digit represents temperature), the second digit 900 represents the nozzle pressure in bar, and the third digit 888 represents the density in kg/m³.

I hope this is understandable.
