Internal engine temperatures reduced by using more efficient cooling techniques.

This provides the rich mixture required to sustain operation at low engine temperatures.

I check the engine temperature with my hand.

The rise in their engine temperatures, which had reached alarming levels, declined somewhat.

Four oil coolers also ensured that the engine temperature never exceeded 110 C.

The Argonne study found that the damage results from the lower engine temperature during idling.

Stage six refers to the engine temperature and low pressure shaft speed.

This in turn resulted in a higher overall engine temperature.

"Which do they use as the mark: the speed, or the engine temperature?"

The only real worry here was his engine temperature.
