Description
Technical field
The utility model relates to a kind of air-intake device for internal combustion engine, particularly a kind of air-intake of combustion engine air heating apparatus.
Background technique
At present, known air-intake of combustion engine air temperature changes with variation of ambient temperature.The gas handling system of internal-combustion engine can not remain on ambient air temperature, control optimum temperature range required when empty combustion is abundant to be mixed now, yet has the air of uniform temperature value just can make fully mixing of empty combustion, and fully mixing of only free combustion could perfect combustion.Ambient temperature mostly has-15 ℃-45 ℃ the temperature difference.When ambient temperature was in high temperature, near the abundant mixing of empty combustion optimum temperature, empty combustion mixed abundant, burn fully, and energy-saving and environmental protection, power is bringd into play, the emission standard height.But when ambient temperature was in low temperature, empty combustion mixed just insufficient, and incomplete combustion, pollutes at waste, and power is not played well, and emission standard is low, and this is the problem that remains our thinking and will solve.
Summary of the invention
Fully mix required best intake temperature scope in order to make internal-combustion engine reach empty combustion.It is a kind of when ambient temperature is low that the utility model provides, the heat that produces when utilizing internal combustion engine, the device of lifting and maintenance intake air temperature, i.e. air-intake of combustion engine air heating apparatus.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of air-intake of combustion engine air heating apparatus is connected with one or form the air ventilation pipeline of perforation by many between oil sump, crankcase and the intake manifold of internal-combustion engine.Described oil sump, crankcase and intake manifold single joint and twin adapter are housed respectively and on single, double joint, be equipped with respectively in gas flow tube and outside gas flow tube make it to form the air ventilation pipeline of a perforation.One end of the interior gas flow tube in the described oil sump is connected with the twin adapter of crankcase inboard, and its other end is connected with the twin adapter of oil sump inboard; Described outer gas flow tube has two sections, the one section outer gas flow tube that wherein has suction port and air-strainer is connected with the twin adapter in the oil sump outside, and an end of the outer gas flow tube of another section is connected with the twin adapter in the crankcase outside, and the other end is connected with single joint of intake manifold.
The beneficial effects of the utility model are: the heat energy that produces when utilizing internal combustion engine, can heat to Cryogenic air.Make it to reach empty combustion and fully mix required optimum air temperature.Guarantee that empty combustion fully mixes, perfect combustion, energy-saving and environmental protection.When ambient air temperature is high, can utilize the auxiliary internal-combustion engine heat radiation of this equipment, simple in structure.
The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, air-intake of combustion engine air heating apparatus of the present utility model is to be connected with one or form the air ventilation pipeline of perforation by many between oil sump 1, crankcase 2 and the intake manifold 3 at internal-combustion engine.Described oil sump 1, crankcase 2 and intake manifold 3 single joint 4 and twin adapter 5,6 are housed respectively and on single, double joint 4 and 5,6, be equipped with respectively in gas flow tube 7 and outside gas flow tube 8 and 9 make it to form the air ventilation pipeline of a perforation.One end of the interior gas flow tube 7 in the described oil sump 1 is connected with the twin adapter 6 of crankcase 2 inboards, and its other end is connected with the twin adapter 5 of oil sump 1 inboard; Described outer gas flow tube has two sections, the one section outer gas flow tube 8 that wherein has suction port 10-1 and air-strainer 11-1 is connected with the twin adapter 5 in oil sump 1 outside, and an end of the outer gas flow tube 9 of another section is connected with the twin adapter 6 in crankcase 2 outsides, and the other end is connected with single joint 4 of intake manifold 3.Described intake manifold's 3 one ends have suction port 10 and air-strainer 11, and the other end is connected with the intake manifold 13 that has closure 12.Also be provided with an air regulation valve 14 on described intake manifold's 3 single joint 4 and the outer gas flow tube 9 between the twin adapter 6 on the crankcase 2.
The utility model is I. C. engine oil drain pan 1, crankcase 2 and intake manifold 3, selects a correct position, respectively opens a hole, installs pipe joint and gas flow tube, and size specification is decided according to required quantity of hot air.When ambient temperature is low, just can with the part air through entering oil sump 1, crankcase 2 is heated, and takes away the part heat in oil sump 1, the crankcase 2, enters into intake manifold 3 again, merge into hot air with other air, finish the temperature-rise period before air enters cylinder.Reach empty combustion and fully mix required optimum air temperature.Make empty combustion fully mixing, perfect combustion.Improve power of IC engine and emission standard.
When the utility model is in the ambient temperature height, when internal-combustion engine does not need hot air, also can be used as the auxiliary heat dissipation equipment of internal-combustion engine, when ambient temperature is low, promote retainer as intake air temperature, be a kind of technical equipment multiple use.
