    摘要： A system for detecting contamination of an air filter for an internal combustion engine includes an air pressure sensor disposed downstream of the air filter, an air flow sensor disposed in an air intake system of the engine, and a control module in communication with the air pressure sensor and the air flow sensor. The control module is configured to estimate an atmospheric pressure based on a signal received from the air pressure sensor. The control module is further configured to determine a contamination level of the air filter based on an air flow rate provided by the air flow sensor and a pressure drop across the air filter based on a pressure difference between the estimated atmospheric pressure and a second pressure measurement from the air pressure sensor that corresponds to the provided air flow rate.

    摘要： A system for a parallel intake engine includes first, second, third, and fourth modules. The first module estimates a total mass air flow (MAF) into the engine based on a cross-sectional area of a throttle and a pressure ratio across the throttle. The second module estimates first and second MAFs through first and second induction paths, respectively, based on the estimated total MAF and a factor. The third module calculates first and second differences between the estimated first and second MAFs and first and second MAFs measured by first and second MAF sensors, respectively. The fourth module detects failures of the first and second MAF sensors based on the first and second differences and first and second thresholds, respectively.

    摘要： A system according to the principles of the present disclosure includes a fuel volatility module, a temperature generation module, and a fuel control module. The fuel volatility module estimates a volatility of fuel provided to an engine based on an engine torque and an engine speed. The temperature generation module generates a temperature of an intake valve of the engine. The fuel control module selectively increases an amount of fuel provided to the engine based on the temperature of the intake valve, the engine torque, and the fuel volatility.

    摘要： An engine control system comprises a signal deviation module, a variation determination module, and a sensor diagnostic module. The signal deviation module receives a signal from a sensor monitoring an operating condition of an engine and determines a plurality of signal deviations. Each of the plurality of signal deviations is based on a magnitude of a difference between the signal at a first time and the signal at a second time. The second time is different than the first time. The variation determination module generates a variation value based on the plurality of signal deviations during a period. The sensor diagnostic module determines a state of the sensor based on the variation value.

    摘要： A system for an engine with a turbocharger system includes a rate determination module, a limiting rate selection module, a throttle inlet absolute pressure (TIAP) calculation module, and a throttle control module. The rate determination module generates a pressure rate value based on a pressure difference between a current TIAP signal from a TIAP sensor and a previous TIAP signal. The limiting rate selection module selects a limiting rate based on the pressure rate value. The TIAP calculation module generates a calculated TIAP signal based on the limiting rate and the current TIAP signal. The throttle control module generates a throttle control signal based on the calculated TIAP signal and actuates an inlet throttle valve of the engine based on the throttle control signal.
