including measurement of inducted mass air flow (MAF) from mass air flow sensor120; engine coolant temperature (ECT) from temperature sensor112coupled to cooling sleeve114; a profile ignition pickup signal (PIP) from Hall effect sensor118(or other type) coupled to crankshaft40; throttle position...
Controller 12 may receive various signals from sensors coupled to engine 10, in addition to those signals previously discussed, including measurement of inducted mass air flow (MAF) from mass air flow sensor 120; engine coolant temperature (ECT) from temperature sensor 112 coupled to cooling sleeve...
flow of coolant from the first stage recirculation flow increases. As this flow increases the trend is for the intermediate pressure density to drop towards suction pressure. As can be seen in the equation above and in FIG. 8, the mass flow capacity drops linearly with intermediate pressure den...
flow (MAF) from mass air flow sensor 110 which is coupled to throttle body 58 upstream of air bypass passageway 94 to provide a total measurement of airflow inducted into intake manifold 44 via both throttle body 58 and air bypass passageway 94; engine coolant temperature (ECT) from ...
“OLED”) display, a solid state display, etc.). The dashboard display104communicates information to the user, such as vehicle speed, current fuel tank level, engine coolant temperature, engine revolutions per minute (RPM), oil pressure, battery state, faults, and/or warnings, etc. ...
airflow (MAF) sensor 64 also provides a signal 66 indicative of the compressor intake airflow to the ECU 24. Additional sensory inputs can also be received by the ECU along signal line 62 such as engine coolant temperature, engine speed, and throttle position. Additional operator inputs 68 ...
Kind Code: A1 Abstract: The turbine has a coolant channel (2b) integrated in a turbine housing (2a). The coolant channel extends at a rotatably mounted shaft (4a) in the turbine housing and is arranged on a side of a turbine running wheel (4) turned away from a bearing housing (3a)...
