Characteristic map thermostat: Notes
The characteristic map thermostat is attached to the housing of the coolant pump.
The coolant temperature influences:
- Fuel consumption
- Power
- Factor of quality of the mixture formation
- Pollutant emission
- Mechanical load on the components
The optimization of these variables does not permit a fixed temperature value if there are different speed and load states. The optimization requires a temperature range that corresponds to each operating point. The characteristic map thermostat achieves an approximation of the optimal temperature.
