摘要： An engine control system according to the principles of the present disclosure includes a manifold air pressure (MAP) determination module, a boost control module, and a throttle control module. The MAP determination module determines a desired MAP based on a driver torque request. The boost control module controls a boost device based on the desired MAP and a basic boost pressure. The boost device is actuated using boost pressure and the boost pressure is insufficient to actuate the boost device when the boost pressure is less than the basic boost pressure. The throttle control module controls a throttle valve based on the desired MAP and the basic boost pressure.

摘要： A lubrication torque limit module includes a temperature module that determines a temperature of an engine and generates an engine temperature signal. A limit module generates a torque limit signal based on the temperature signal and a speed of the engine. The torque limit signal identifies an indicated torque maximum limit. A torque arbitration module limits indicated torque of the engine based on the indicated torque maximum limit. The indicated torque of the engine is equal to an unmanaged brake torque of the engine plus an overall friction torque of the engine.

摘要： A method includes: retarding spark timing relative to a predetermined spark timing when an engine torque output reduction is requested for a gear shift; estimating a first torque output of an engine based on N cylinders of the engine being fueled, an engine speed, an air per cylinder (APC), and the predetermined spark timing; estimating a second torque output of the engine based on M cylinders being fueled, the engine speed, the APC, and the spark timing. determining an initial pressure ratio across a turbocharger compressor; determining an adjustment based on M and the first and second torque outputs; generating a desired pressure ratio across the turbocharger compressor based on the adjustment and the initial pressure ratio; and controlling opening of a turbocharger wastegate based on the desired pressure ratio. N is a total number of cylinders of the engine and M is less than or equal to N.

摘要： A gasket for an internal combustion engine comprises a sheet portion and a PCV impaction surface formed in the sheet portion. The PCV impaction surface is configured to extend across, and partially close, a crankcase ventilation system passage. A plurality of apertures extend through the PCV impaction surface and are configured to allow crankcase gas to flow freely in the crankcase ventilation system passage while the PCV impaction surface is configured to separate oil droplets from the crankcase gas by impaction of the droplets with the surface.
