| Yes, Ducati's fuel injection CPU has a coolant temperature sensor and an air temperature sensor.
Engines need more fuel when for a cold start as there is no heat in the ports and chambers to keep the fuel atomized as vapor, so it condenses. Fuel as a liquid burns very badly in the combustion chamber, so throwing more at it ensures enough stays as vapor for some sort of combustion. Injected engines get a very nice fuel spray from the injectors and this is why injected engines behave better when cold.
A coolant temperature sensor is used so that the computer can add additional fuel to its fuel map while the engine is warming up, and also to retard ignition timing when the engine gets too hot. The computer stops enriching due to low temperature at between 80 and 90°C. So at least from a fuel correction standpoint, the proper operating temperatures for a fuel injected Ducati is above these temperatures.
Further, on a cold morning the air is denser so an air temperature sensor will prompt the CPU to add fuel to its 20°C ambient fuel map to compensate. If the day is hotter than 20°, it reduces fuel.  |
