摘要： An engine control system includes a scavenging module that generates a scavenging signal when both a driver torque request is greater than a predetermined torque threshold and a rotational speed of an engine crankshaft is less than a predetermined speed threshold. A cam phaser control module controls intake and exhaust cam phasers based on the scavenging signal such that opening times of intake and exhaust valves of a respective cylinder overlap.

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 air-per-cylinder (APC) security system for a vehicle comprises an APC determination module, an APC threshold determination module, and an APC diagnostic module. The APC determination module determines first and second APC values for first and second cylinders of an engine, respectively, based on mass airflow (MAF) into the engine. The APC threshold determination module determines an APC threshold based on the first APC value and a spark timing for the first cylinder. The APC diagnostic module selectively diagnoses a fault in the APC determination module when the second APC value is greater than a sum of the first APC value and the APC threshold.

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.
