摘要： A knock detection module for an engine comprises a statistics storage module and a processing module. The statistics storage module stores M times N vibration profiles corresponding to M zones of operation of the engine and N cylinders of the engine, wherein M and N are integers greater than one. The processing module determines in which one of the M zones the engine is operating and determines whether knock has occurred for one of the N cylinders by comparing measured vibration data with a selected one of the vibration profiles corresponding to the one of the M zones and the one of the N cylinders.

摘要： A system for a vehicle includes a humidity determination module, a specific humidity module, and a parameter control module. The humidity determination module determines a first specific humidity of air based on a relative humidity of the air measured by a humidity sensor in an intake system of the vehicle. The specific humidity module sets a second specific humidity of the air equal to one of the first specific humidity and a predetermined specific humidity of the air in response to a comparison of a mass air flowrate (MAF) into an engine and a predetermined flowrate. The parameter control module controls at least one operating parameter of an engine based on the second specific humidity.

摘要： A control system for an engine includes a block heater determination module, an adjustment module, and an engine control module. The block heater determination module generates a block heater usage signal based on ambient temperature, measured engine coolant temperature, and a length of time of the engine being off prior to engine startup. The adjustment module generates a temperature signal based on the ambient temperature. The engine control module determines a desired fuel mass for fuel injection at engine startup based on the temperature signal when the block heater usage signal has a first state. The engine control module determines the desired fuel mass at engine startup based on the measured engine coolant temperature when the block heater usage signal has a second state.
