A fluid heating pre-start system includes a fluid circuit. The fluid circuit includes a circulating pump, a heat exchanger, and a fluid jacket coupled to a piece of equipment. The pre-start system includes a heater positioned to heat the fluid in the fluid circuit using the heat exchanger. The pre-start system includes a controller positioned to control the operation of the fluid circuit and the heater. The pre-start system may be run until the piece of equipment is preheated to a desired temperature before the piece of equipment is activated.

The present invention provides a preheating, lubricating, and cooling system that oil essentially used for lubrication, wear resistance, and cooling of an internal combustion engine, industrial equipment, or a mobile vehicle is used as a preheating medium, a manager supplies the oil most optimized for load operation of equipment through a preheating system separated from the existing main oil system, and an oil supply path uses a path of the existing oil system, so that the preheating and the load operation are facilitated during an extremely cold season and an extremely hot season, and a normal operation is possible even in a case of being immediately stopped after the operation.

A system for an engine includes a heat shield system and a crankcase ventilation system. The heat shield system includes at least one heat shield panel. The crankcase ventilation system includes at least one breather, at least one outlet, and at least one conduit extending from the at least one breather to the at least one outlet. A portion of the at least one conduit is coupled to the at least one heat shield panel to directly transfer heat from the heat shield system to the at least one conduit.

A variety of methods and arrangements for reducing noise, vibration and harshness (NVH) in a skip fire engine control system are described. In one aspect, a firing sequence is used to operate the engine in a skip fire manner. A smoothing torque is determined that is applied to a powertrain by an energy storage/release device. The smoothing torque is arranged to at least partially cancel out variation in torque generated by the skip fire firing sequence. Various methods, powertrain controllers, arrangements and computer software related to the above operations are also described.

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.

An oil temperature increasing system and method for an eco-friendly vehicle includes: an oil-temperature detector configured to detect a temperature of oil flowing to a motor and a transmission by an electric oil pump; and a controller configured to receive a detection signal of the oil-temperature detector, and apply a current for increasing temperature to the motor when the oil temperature is less than a predetermined reference temperature. A temperature of the motor is increased by the current applied to the motor, such that the oil temperature is increased by heat of the motor.

A vehicle may include a driving motor supplying driving force to vehicle wheel; a power converter using a coil provided in the driving motor to transform power input from the external power source; a battery charged according to counter electromotive force of the driving motor in a regenerative braking mode, charged according to the power transformed by the power converter in a charging mode, and supplying driving power to the driving motor in a driving mode; an oil pump supplying oil to the driving motor; a detector detecting temperature of the oil; and a controller controlling the oil pump to be operated in a warm-up mode when the oil temperature detected by the detector is less than a first threshold temperature and the battery is in the charging mode, and applying reference power to the oil pump to move the oil to the driving motor in the warm-up mode.

A refiner device for refining of a liquid, wherein the refiner device includes a housing provided with a liquid inlet for unrefined oil or fuel, a liquid outlet for refined oil or fuel, an air inlet for supplying a flow of air into the housing, and an air outlet for discharging air and contaminants removed from the liquid. The refiner device further includes a liquid receiving plate arranged inside the housing, the refiner device arranged such that when liquid has passed through the liquid inlet during operation of the device, the liquid is contacted with an upper surface of the liquid receiving plate before it reaches the liquid outlet, and at least one heating element arranged to directly or indirectly heat the liquid while the liquid is in contact with the liquid receiving plate. The refiner device further includes a hollow air-guiding member arranged at the liquid receiving plate.

The present invention relates to automotive products, as well as uses thereof, which can facilitate warming of engine oil in an energy efficient and, therefore, more environmentally friendly manner. More specifically, a fluid reservoir is disclosed that includes a double walled vessel that defines a fluid containing compartment and has a self-contained region that shares a wall with the fluid containing compartment. A composition in the self-contained region at least partially covers the shared wall surface, and one or more light sources are positioned in the self-contained region to induce a phase change in the composition. The composition includes a phase-change material (PCM) and a molecular switch material. This fluid reservoir can be used to heat oil in an engine or oil pan.
