A lubricating system of an engine equipped with an idle reduction system includes an oil cooler, a remotely operable valve configured to open and close a bypass passage that bypasses the oil cooler, and an electronic control unit. The electronic control unit is configured to perform the steps of: controlling the valve so that a temperature of lubricating oil approaches a target temperature; and lowering the target temperature when an average torque of the engine is less than a predetermined threshold.

A connection device for connecting a ventilating line to an intake air flow guide of an internal combustion engine, wherein the connection device has a non-return valve for preventing a flow from the intake air flow guide into the ventilating line. The connection device has at least one hole which is arranged upstream of the non-return valve and connects an interior chamber of the connection device to a surrounding area of the connection device.

A cooling system for an outboard motor of a marine vessel is provided. The cooling system includes an oil sump housing having an inner housing wall and an outer housing wall. The inner housing wall defines a transmission mounting cavity, and the inner housing wall and the outer housing wall defines an oil containment cavity that at least partially surrounds the transmission mounting cavity. The cooling system further includes a first sprayer nozzle and a second sprayer nozzle. Both the first sprayer nozzle and the second sprayer nozzle are coupled to the oil sump housing and configured to spray cooling fluid within the transmission mounting cavity onto an inner surface of the inner housing wall.

A temperature-controlling water valve is provided. An adjusting assembly is assembled within the water valve and includes an adjusting member, a first elastic member, a blocking member and an abutting member. The first elastic member biases the abutting member, and the blocking member is fixed to the adjusting member to block the abutting member from detaching from a receiving hole of the adjusting member. A temperature-controlling assembly includes a valve member and a second elastic member biasing the valve member. Thermal expansion or contraction of a rod member of the valve member drives the valve member to move so that an overlapping area of the valve member and a first passageway of the water valve and an overlapping area of the valve member and a second passageway of the water valve change.

An engine heater system for supplying compressed air to an air brake of a vehicle. The engine heater system including a gas turbine. A compressor fluidly coupled to an air reservoir of the vehicle. The air reservoir fluidly coupled to an air brake of the vehicle. A shaft rotatably attached between the gas turbine and the compressor, and when the gas turbine rotates the shaft, the compressor provides compressed air to the air reservoir of the vehicle for operating the air brake of the vehicle.

A piston oil squirter is selectively opened when an oil temperature is below a threshold oil temperature to transfer heat from the combustion chamber and heat the oil more rapidly when the engine is cold.

A system for circulating coolant including a coolant manifold and a coolant filter hosing. The oil cap and the oil transfer tube act in conjunction to redirect the oil flow. The coolant manifold is able to redirect coolant to the coolant filter and back into the system. The coolant filter is able to filter coolant in the system.

A system and method for a variable displacement internal combustion engine using different types of pneumatic cylinder springs on skipped working cycles to control engine and aftertreatment system temperatures are described. The system and method may be used to rapidly heat up the aftertreatment system(s) and/or an engine block of the engine following a cold start by using one or more different types of pneumatic cylinder springs during skipped firing opportunities. By rapidly heating the aftertreatment system(s) and/or engine block, noxious emissions such as hydrocarbons, carbon monoxide, NO.sub.x and/or particulates, following cold starts are significantly reduced.

Embodiments of a hydraulic reservoir cooler include a backward curve centrifugal fan located rearward of a vented front cover of the cooler, the centrifugal fan having a center point “c” and a radius “r”; and a core area including fins and a manifold in fluid communication with a hydraulic fluid tank, the core area being located between the vented front cover and the backward curve centrifugal fan and including: a straight vertical portion extending in height less than an uppermost upper end of the centrifugal fan; a straight horizontal portion located above the uppermost upper end of the centrifugal fan; and a curved portion connecting the straight vertical and horizontal portions, the curved portion having a center point “C” and a radius “R”; where C is located above c and R is greater than r. The cooler may be adapted for use with an agricultural pumper truck.

The present disclosure relates to the field of energy storage, and provides a rapid-response energy storage system and a using method thereof. The system comprises an air storage chamber, a compressor unit, an expander unit, a compressor unit lubrication station, an expander unit lubrication station, a compressor unit oil cooler, an expander unit oil cooler, a compressor unit oil pump and an expander unit oil pump; an outlet of the compressor unit communicates with an inlet of the air storage chamber through a heating pipe inside the expander unit lubrication station, and an outlet of the air storage chamber communicates with a heating pipe inside the compressor unit lubrication station sequentially through a regulating valve and the expander unit; the compressor unit lubrication station, the compressor unit oil pump, an oil way inside the compressor unit and the high-temperature side of the compressor unit oil cooler are sequentially connected end to end to form a first oil circulation loop; and the expander unit lubrication station, the expander unit oil pump, an oil way inside the expander unit and the high-temperature side of the expander unit oil cooler are sequentially connected end to end to form a second oil circulation loop. According to the present disclosure, rapid responses can be achieved and the lubricating oil can be heated without the consumption of external thermal energy.
