Why do diesel engines run cooler?

Leaner Air-Fuel Ratio

Lean out the fuel and the engine runs cooler. Add fuel to the mix and combustion temps and exhaust gas temperature goes up. This is why diesels run a leaner air-fuel ratio than gas engines. In fact, some diesels utilize an air-fuel ratio as high as 90:1 or 100:1 at idle.
