Abstract: A system includes a first heater positioned in or proximate to an exhaust aftertreatment system in exhaust gas-receiving communication with an engine, a second heater positioned downstream of the first heater, and a controller coupled to the first and second heaters. The controller is structured to determine, based on information indicative of a temperature regarding the exhaust aftertreatment system, that the temperature is below a temperature threshold; receive information regarding a characteristic of a battery coupled to the first heater and the second heater; control the temperature regarding the exhaust aftertreatment system without using the first or second heaters in response to determining that the characteristic of the battery is below a first threshold; and control a temperature regarding the exhaust aftertreatment system using the first heater in response to determining that the characteristic of the battery is above the first threshold but below a second threshold.

Abstract: An integrated fan and pump drive system.

Abstract: A cooling system for an engine is disclosed. In a first embodiment, the cooling system may comprise a heat exchanger, a pump coupled to the heat exchanger, an EGR cooler coupled to the pump, and a first valve coupled to the EGR cooler and the heat exchanger. When the first valve is in a first position, the first valve directs a coolant to the heat exchanger and when the first valve is in a second position, the heat exchanger is bypassed and coolant flows directly to the pump. It is an advantage for a cooling system to utilize a valve to maximize the rate a coolant flows throughout the system when the valve is in an open position and also to warm up an engine when the valve is in a closed position.

Abstract: An internal combustion engine includes an engine block having an oil rifle. A cylinder liner carried by the engine block includes a bottom end. A piston cooling nozzle coupled with the engine block includes an inlet in communication with the oil rifle, a tube, and a bracket coupled with the tube. The bracket engages the bottom end of the cylinder liner.

Abstract: A replaceable cylinder liner for an internal combustion engine. The position of the liner within the block is established by a midstop. An interference fit below the midstop seals the bottom end of a cooling passage that extends around the liner. The top end of the cooling passage is sealed by an o-ring, and when the engine is warmed up by an interference fit also. The top of the cooling passage is close to the top dead center position of the top piston ring, and reduces the temperature of the top piston ring.

Abstract: A method and apparatus for providing an improved static timing between a crankshaft and a camshaft in an internal combustion engine. The crankshaft and camshaft are locked into predetermined rotational positions to set the desired timing between the crankshaft and camshaft. The camshaft is locked into its predetermined rotational position using a camshaft timing member positioned between a flat portion formed on an outer peripheral surface of camshaft and an adjacent portion of said engine, such as the cylinder head. This positioning of the camshaft timing member prevents the camshaft from rotating and locks the camshaft into the desired predetermined rotational position for setting the static timing with respect to the crankshaft. The crankshaft in locked into its predetermined position using a crankshaft timing pin inserted through the engine block and positioned into a slot formed in a counterweight on the crankshaft.

Abstract: An articulated piston for use in heavy duty diesel engines including a piston crown having an outer surface, a peripheral pending side wall and an inner surface having a pair of pin bosses extending downwardly from the inner surface with the inner surface and the pin bosses defining a hollow cooling cavity opening downwardly and extending about a circumference of the piston crown and a piston skirt with the piston skirt including a first longitudinal plane containing a pair of diametrically opposed bores for receiving a wrist pin for connection to the bosses of the crown and defining two semi-cylindrical thrust and non thrust surfaces of the skirt with a thickness of the non thrust surface being less than a thickness of the thrust surface and a second longitudinal plane, perpendicular to the first plane thereby dividing the piston skirt into four peripheral quarters.
