Abstract: A cooling jacket for an engine has upper and lower bodies. The upper body includes a plurality of upper portions. Each upper portion has a top orifice and a bottom orifice. The lower body is located below the upper body and includes a plurality of lower portions. Each lower portion has a lower orifice aligned with a respective one of the bottom orifices so as to permit a coolant to flow through the lower orifice and into the bottom orifice. The coolant flows from that lower portion to the respective one of the upper portions. Each upper portion has at least one upper passageway extending through that upper portion from the bottom orifice to the top orifice so that the coolant entering the upper passageway of that upper portion flows through the upper portion to the top orifice.

Abstract: An internal combustion engine includes a crankshaft rotatably supported by an engine block, and rotatable about a crank axis. A control shaft is rotatably supported by the engine block, and rotatable about a control axis. A link rod is rotatably connected to the crankshaft. A lower connecting rod includes a first end rotatably connected to the link rod, and a second end rotatably connected to the control shaft. An upper connecting rod is rotatably connected to the link rod and a piston. The second end of the lower connecting rod and the control shaft are rotatably connected at a location offset from the control axis to define an eccentric connection relative to the control axis. Rotation of the control shaft about the control axis rotates the second end of the lower connecting rod about the control axis to adjust a compression stroke length of the piston.

Abstract: An engine assembly includes an oil pan including an oil pan body defining a cavity. The oil pan body includes a dividing wall separating the cavity into a first compartment and a second compartment. The engine assembly further includes a drip tray coupled to the oil pan body. The drip tray is disposed over the second compartment and can direct oil to the first compartment where the oil is warmed up initially in order to minimize the time it takes to heat the oil when the internal combustion engine is warming up. The engine assembly further includes an oil scraper coupled to the oil pan body. The oil scraper is disposed over the drip tray and can scrape oil from a crankshaft.

Abstract: A system and method of thermal management for an engine are provided. The system includes an engine, an electrical water pump, and a controller. The controller has a processor and tangible, non-transitory memory on which is recorded instructions. Executing the recorded instructions causes the processor to continuously monitor the temperature of the cylinder head and the temperature of the coolant. If the monitored temperatures of the cylinder head and the coolant are below predetermined thresholds, the processor executes a first control action, in which the pump remains off and the coolant remains stagnant. If either of the monitored temperatures of the cylinder head or coolant reaches the respective predetermined threshold, the controller initiates a second control action, which requires the controller to signal the pump to turn on and circulate coolant. The controller then determines the desired operating speed of the electrical water pump based on engine load.

The circuit additionally includes a remote reservoir for receiving sump oil via the first passage and an orifice in the first passage for controlling an amount of sump oil transferred to the reservoir. The circuit additionally includes an active first valve in the first fluid passage for selectively opening and closing communication between the sump and the reservoir. The circuit also includes a second fluid passage in communication with the auxiliary reservoir for returning the oil from the reservoir to the sump. Furthermore, the circuit includes an active second valve arranged in the second passage for selectively opening and closing communication between the reservoir and the sump.

Abstract: A system for detecting engine events includes an engine assembly, and an acoustic emission sensor mounted on the engine assembly. A controller has a processor configured to execute stored instructions and is programmed to convert the signal into one or more frequency components, filter the signal with a band pass filter and determine a power value of each of the one or more frequency components within the range of frequencies of the band pass filter. The controller then compares the power value of each of the one or more frequency components to a reference value associated with acoustic emissions in the engine assembly during a baseline engine cycle. The controller adjusts at least one operating parameter of the engine assembly if the power value differs from the reference value by at least a predetermined amount. A corresponding method of controlling an engine assembly is disclosed.
