摘要： A solenoid driver generates a current signal to drive a solenoid of a lifter oil manifold assembly (LOMA) to switch a displacement on demand engine between activated and deactivated modes. The solenoid driver includes a current module that generates the current signal based on a duty cycle signal and a switching module that regulates the duty cycle signal based on the activated and deactivated modes. The duty cycle signal is 100% for a first period after the engine switches to the deactivated mode and is variable for a second period after the first period.

摘要： A control system and method for detecting a hydraulic system leak in an engine includes a pressure sensor that senses a first pressure reading of a hydraulic fluid supply at a first time and a second pressure reading of said hydraulic fluid supply at a second time. A comparison module calculates a pressure ratio based on the first and second pressure readings and signals a fault condition based on a relationship between the pressure ratio and a pressure threshold.

摘要： An engine control system comprises an intake valve deactivation module and an exhaust valve deactivation module. The intake valve deactivation module deactivates an intake valve of a cylinder of an engine based on an engine stop request such that the intake valve remains closed. The exhaust valve deactivation module deactivates an exhaust valve of the cylinder after the intake valve deactivation module deactivates the intake valve such that the exhaust valve remains closed.

摘要： A vehicle biodiesel fuel diagnostic method may include determining a biodiesel fuel concentration of fuel added to a vehicle fuel tank during a fueling event at a fueling location and determining the fueling location. The biodiesel fuel concentration and fueling location may be transmitted to an information system where the concentration and location are stored in a database. The method may further include indicating an abnormal biodiesel fuel condition in the database when the biodiesel fuel concentration is outside of a predetermined range.

摘要： Cloud point monitoring systems for determining a cloud point temperature value for diesel fuel are provided. In one exemplary embodiment, a cloud point monitoring system receives diesel fuel in the tubular conduit and propagates light through the diesel fuel. The cloud point monitoring system further determines a cloud point temperature value indicative of a cloud point of the diesel fuel based on a light intensity level of the light that has propagated through cooled diesel fuel.

摘要： A system to reduce rotational speed variations of a crankshaft includes a controller, a braking device, and a control module. The controller deactivates at least one cylinder in an internal combustion engine. The braking device applies a braking torque to the crankshaft when at least one cylinder is deactivated. The control module determines whether the controller has deactivated at least one cylinder and selectively synchronizes the braking torque with a crankshaft rotational speed.

摘要： An oil monitoring system includes a level module, a limit module and an remedial action module. The level module is configured to determine N oil levels of an engine of a vehicle, where N is an integer greater than 1. The limit module is configured to determine an oil level trend based on the N oil levels and estimate when a level of oil in the engine is to be outside the predetermined range based on the oil level trend. The remedial action module is configured to perform a remedial action based on the estimate of when the level of the oil is to be outside the predetermined range.
