«The prevailing thinking has been that as the oceans warm due to increasing
atmospheric greenhouse gases, the
oxygen content of the oceans should decline,» Thunell says.
It shows that the
content of
atmospheric oxygen has taken several ups and downs.
The system monitors throttle position, engine temperature, intake - manifold pressure,
atmospheric pressure, exhaust - gas
oxygen content, and intake - air temperature.
A 32 - bit, 80 MHz central processor unit (CPU) within the Ridgeline's powertrain control module calculates injection timing and duration after assessing an array of sensor signals: crankshaft and camshaft position, throttle position, coolant temperature, intake manifold pressure and temperature,
atmospheric pressure, and exhaust - gas
oxygen content.
Mate, the decreased
oxygen content at altitude is a function of decreased density, not of changed
atmospheric composition.
