A heat management system disclosed herein is used for a vehicle. The heat management system may include an electric device, a first heat exchanger, a second heat exchanger, a first channel, a second channel, a first pump, a second pump, a first channel valve, a second channel valve, a bypass channel, and a controller. The controller may be configured to, when one of the first pump and the second pump operates abnormally, control the first channel valve and the second channel valve such that the flow of the first heat medium from both of the first channel and the second channel to the first heat exchanger is allowed and activate the other of the first pump and the second pump.

Heat management system for vehicle

An object of the present invention is to provide an exhaust system component having excellent properties to be located in an exhaust flow path from an internal combustion engine, particularly, an exhaust system component having an extended use-life. The exhaust system component of the present invention for an internal combustion engine has a self-healing ceramic material and an electric heater for heating the self-healing ceramic material. In particular, the exhaust system component of the present invention is an oxygen sensor having a detection element and an electric heater, wherein the detection element has a solid electrolyte layer, a reference-side electrode layer, an exhaust-side electrode layer, and a diffusion layer and/or a trap layer each composed of a self-healing ceramic material.

Method for controlling an internal combustion engine having an exhaust system component including a self-healing ceramic material

An object of the present invention is to suppress a blockage caused by oil particles in an upstream side of a filter in an oil removal apparatus that collects oil particles in a filter disposed between an anode and a cathode. While an internal combustion engine is operative, application of a voltage to a bipolar electrode is controlled such that a voltage application period, in which the voltage is applied to the bipolar electrode, and a voltage application stoppage period, in which application of the voltage to the bipolar electrode is stopped, are repeated alternately at predetermined periodic intervals.

Oil removal apparatus

An object of the present invention is to suppress conduction between an anode and a cathode caused by condensed water in an oil removal apparatus in which oil particles are trapped in a filter disposed between the anode and the cathode. A bipolar electrode having an anode and a cathode that extend in a flow direction of blow-by gas, and a filter formed from an insulator and disposed between the anode and the cathode of the bipolar electrode are housed in a case. Further, when the oil removal apparatus is installed in a vehicle, the bipolar electrode and the filter are disposed in the case so as to be arranged in a horizontal direction, and a space through which the blow-by gas flows is formed between a lower inner wall surface of the case, and the bipolar electrode and filter.

An oil separator includes a case, electrode plates, filters, and a power supply unit. The electrode plates are arranged in the case with a space in between such that any two adjacent electrode plates face each other. The filters are made of an electrically insulating material and each arranged between any two adjacent electrode plates. The power supply unit is connected to the electrode plates and applies voltage between any two adjacent electrode plates, thereby creating a potential difference between the adjacent electrode plates. The filling factor of each filter is in a range from 0.005 to 0.03. The voltage applied between any two adjacent electrode plates by the power supply unit is in a range from 0.5 to 5 kV. The distance between any two adjacent electrode plates is in a range from 3 to 20 mm.

Oil separator

The invention relates to a fluid transport pipe. A first unit channel in which a channel cross-sectional area continuously decreases toward a downstream side and a second unit channel in which a channel cross-sectional area continuously increases toward the downstream side are alternately combined. A ratio A (=L/{[Smax]-[Smin]}) is set within a range in which a drag reduction rate Rbecomes a positive value. The fluid transport pipe includes: a first opening formed in a channel wall of the first unit channel; a second opening formed in a channel wall of the second unit channel; and a bypass channel that allows by-passing of a flow from the first unit channel to the second unit channel through the openings.

Fluid transport pipe

Embodiments of the present disclosure may suppress conduction between an anode and a cathode caused by condensed water in an oil removal apparatus in which oil particles are collected in a filter disposed between the anode and the cathode. An insulating layer may be sandwiched either between the filter and at least one of the anode and the cathode of the bipolar electrode, or within the filter so as to extend in a flow direction of blow-by gas, and may have an insulating property so as to prevent condensed water generated when moisture in the blow-by gas condenses, from connecting the anode and the cathode of the bipolar electrode.

The influenced of condensed water on an EGR device is alleviated. A device () that controls a cooling system including adjusting means for being able to adjust a circulation amount of coolant in a first flow passage, including an engine cooling flow passage, an EGR cooling flow passage and a radiator flow passage, and a second flow passage, including the engine cooling flow passage, the EGR cooling flow passage and a bypass flow passage and not including the radiator flow passage, includes: measuring means for measuring a temperature of the coolant; limiting means for limiting circulation of the coolant at starting an internal combustion engine; and control means for circulating the coolant preferentially through the second flow passage via control over the adjusting means based on the measured temperature in a period in which circulation of the coolant is limited.
