  • Patent number: 10316761
    Abstract: A vehicle propulsion system includes a controller configured to generate a control signal that dictates operation of a propulsion system of a vehicle having an engine and an electrically driven superturbocharger or a turbo-compounding turbine. Responsive to determining that the vehicle is one or more of entering into or traveling within an airflow restricting area, the controller is configured to change the operation of the propulsion system of the vehicle by reducing a power output by the engine. The controller is configured to reduce the power output by the engine to increase a power output of the electrically driven superturbocharger or the turbo-compounding turbine to propel the vehicle through the airflow restricting area.

  • Patent number: 9097172
    Abstract: An engine control system for a vehicle comprises a pump control module and a heating request determination module. The pump control module disengages a switchable water pump from an engine upon startup of the engine. The heating request determination module generates a heat request signal that indicates whether heating of a passenger cabin of the vehicle has been requested based on ambient air temperature, humidity of ambient air, and a status of an air conditioner clutch. The pump control module selectively engages the switchable water pump after the heat request signal is generated.

  • Patent number: 8474417
    Abstract: An air-cooled general-purpose engine includes: a cooling fan fixed to one end portion, protruding outward from one end wall of an engine main body, of a crankshaft; and a shroud which is mounted to the engine main body, and which defines a cooling-air path between the shroud and the one end wall, the cooling-air path guiding a cooling air blown under pressure from the cooling fan. The air-cooled general-purpose engine includes: an oil pump which pumps up an oil from an oil reservoir; and an oil-supply path which is formed in the one end wall, facing the cooling-air path, of the engine main body, and configured to guide the oil discharged from the oil pump to a valve operating chamber in a head portion of the engine main body, and a jet for jetting the oil is provided in an opening of the oil-supply path, the opening being open to the valve operating chamber.

  • Patent number: 8443766
    Abstract: A method for automatically controlling an internal combustion engine, where, during normal operation in a first controller mode, a charge air temperature controller is set as dominant for a map-controlled thermostatic valve for automatically controlling the charge air temperature (TLL), or, during normal operation in a second controller mode, a coolant temperature limit controller is set as dominant for the map-controlled thermostatic valve for automatically controlling the coolant temperature (TKM). If a charge air temperature sensor fails, the second controller mode is set with the coolant temperature limit controller dominant, and if a coolant temperature sensor fails, the first controller mode is set with the charge air temperature controller dominant.

  • Patent number: 6880495
    Abstract: A method for cooling a motor vehicle engine consists in regulating the volume and the flow rate of a coolant fluid in a hydraulic circuit provided with a branch equipped with an electronically controlled actuator and means forming radiator. The method comprises a step of determining the temperature of the cooling liquid, a step of comparing the temperature of the cooling liquid with a specified threshold temperature from which the engine is said to be hot, and, when the temperature of the fluid is higher than the threshold temperature, the flow rate in the radiator branch is regulated so as to maintain the temperature of the cooling fluid around a specified setpoint value. The curve representing the opening of the thermostat valve based on the temperature of the cooling fluid exhibits an hysteresis around the setpoint temperature. The invention also concerns a device for cooling a motor vehicle engine.

  • Patent number: 6549838
    Abstract: A control strategy and method for controlling friction element engagement and disengagement time for an automatic transmission when the transmission is operating at cold ambient temperatures. During drive-to-reverse or reverse-to-drive friction element engagements with power on, the strategy compensates for a tendency of an oncoming friction element to gain capacity before an off-going clutch loses capacity, thereby avoiding a potential friction element tie-up condition when the transmission is operated with intermediate or high levels of engine torque as the friction elements are sequentially engaged and disengaged during cold rock cycling.

The engine is configured to receive a predetermined combustion-supporting fluid into a plurality of cylinders through a respective intake manifold. The method allows for detecting a full or high load engine condition using the amount of fuel injected into a cylinder per cylinder cycle and/or throttle notch position. The method also allows for sensing a predetermined parameter indicative of a respective ambient condition. The method further allows for selecting a desired value of a predetermined operational parameter that influences peak pressures developed within the cylinders. The desired value being selected based on the value of the parameter indicative of the ambient condition. A comparing step allows for comparing an actual value of the operational parameter against the desired value of that operational parameter.
