A method and system for engine monitoring comprises a plurality of monitoring devices. A master monitoring device is provided which acts as a communication hub for one or more subsidiary monitoring devices. The master monitoring device is incorporated in or directly attached to the internal combustion engine and functions to sense a characteristic of the internal combustion engine. The monitoring device is configured to transmit data representative of the sensed characteristic to a remote application running on a remote device.

A gearbox filler assembly includes a cylindrical insert attached to an interior of a port disposed within a housing of the gearbox. The cylindrical insert has a first end disposed within the port, a second end extending outward from the port and is configured to receive a detachable filler cap, a retaining lip around at least a portion of a first interior circumference proximate to the first end, and a retaining slot around at least a second interior circumference between the retaining lip and the second end. A retaining ring is detachably coupled within the retaining slot. A cylindrical baffle is detachably retained between the retaining ring and the retaining lip.

T-Tube device is made to help oil changers, or adders applying the oil into an engine. It is a movement of adding oil to an engine safely. This device is attached on the quart (container's) mouth or neck. It is removable and attachable; from the neck the Tube runs going to the engine and transmits the liquid (oil) into the engine's body. This device operates easily with no oil dropping around the engine's neck, or around the engine's body of the vehicle. One end connects to the gallon (quart) or bottle's neck. T-TUBE eliminates the need of funnel and or spilling oil on or on the engine's body. It eliminates any increment weather, winds, or heat, hotness, coldness, or wet weather.

An engine assembly includes an air-cooled engine and an external oil reservoir. The engine includes a vertically-oriented crankshaft a crankcase cover having a front portion and a rear portion, wherein the front portion of the crankcase cover and the cylinder head are located forward of a vertical plane that includes the crankshaft axis, a return pump housing formed in the exterior of the crankcase cover, a return pump positioned in the return pump housing, and a return pump inlet formed through the crankcase cover, wherein the return pump inlet is located in the front portion of the crankcase cover and the return pump inlet is located closer to the camshaft than to the crankshaft. The external oil reservoir includes an oil tank and an oil filter assembly.

An engine oil dipstick for monitoring an internal combustion engine comprises a processor and a sensor module. The sensor module is configured to sense a characteristic of the internal combustion engine and to output data representative of the sensed characteristic to the processor. The engine oil dipstick is configured to provide a housing for the processor. The processor is configured to determine a value representative of the firing frequency of the internal combustion engine based on the output data.

An agricultural system that includes a hydraulic fluid tank with a conduit. The hydraulic fluid tank receives and stores hydraulic fluid. A hydraulic fill system couples to and facilitates filling of the hydraulic fluid tank. The hydraulic fill system includes an arm that rotates with respect to the hydraulic fluid tank between an extended position and a retracted position. The arm defines a channel. A connector couples to the arm. The connector defines an opening that receives the hydraulic fluid. A flexible conduit rests within the channel. The flexible conduit includes a first end and a second end. The first end couples to the conduit and the second end couples to the connector

A tube assembly for monitoring a fluid dispensed into a fluid fill port is disclosed. The tube assembly may include a tube body disposed between a first and second open end. A locking portion including a circumferential groove may be defined adjacent to the first open end and a fill portion may be defined at the second open end of the tube body. An aperture may extend through an outer surface of the tube body and a sensor may be inserted into the aperture such that at least a portion of the sensor is positioned within the interior portion of the tube body. The sensor may be configured to monitor at least one fluid characteristic of the fluid that is dispensed into the tube assembly and flows into the fluid fill port.

A plug for a hubcap includes a base configured to fit into and obstruct a port of a hubcap. The base at least partially defines a cavity therein. The plug also includes a cap extending radially outward from the base. The cap defines an opening therein, the opening extending at least partially radially, and a passage extending axially between the opening and the cavity. The opening is in fluid communication with the cavity via the passage.

Systems and methods for capturing fluid change history in a vehicle are provided. A method includes: detecting, by a computer device, a fill cap is removed from an inlet port of a fluid reservoir or a drain plug is removed from an outlet port of the fluid reservoir; activating, by the computer device and based on the detecting, one of a fill sensor and a drain sensor; obtaining, by the computer device, fluid characteristics data from one of the fill sensor and the drain sensor; determining, by the computer device, at least one fluid parameter based on the fluid characteristics data; and transmitting, by the computer device, the determined at least one fluid parameter to a remote system via a communication network that is external to the vehicle.
