Description
Technical field
The utility model belongs to field of internal combustion engine, is related to pre-heating intaking structure built in a kind of use for diesel engine.
Background technique
It is well known that at low ambient temperatures, since the viscosity of machine oil is higher, the starting torque of diesel engine is larger, cylinder wall
Initial temperature is low, and fuel-oil atmozation is poor, and compressed air themperature is difficult to reach fuel oil autoignition temperature, thus there are low for diesel engine
The problem of warm start difficulty.It can start rapidly to guarantee diesel engine under cryogenic, be generallyd use on diesel engine
Electric heating intake air preheater.
Electric heating intake air preheater is installed in diesel engine air inlet pipeline, before the engine is started up with start when it benefit
It is powered with exothermic material and generates heat, heating enters the air in engine cylinder body, to improve the cold-starting of diesel engine
Combustion conditions in performance and Optimization of Diesel Engine cylinder.
Electrical heating preheater is commonly outlet structure currently on the market, and structure is simple, easy for installation, and air easily seals,
But since preheater thickness limits, common external electrical heating preheater is installed, will increase air inlet pipeline length.Part factory
Family is not available external electric heater and realizes diesel engine since by the integrally-built limitation of diesel engine, air inlet pipeline is difficult to lengthen
Charge heating function.
Therefore, pre-heating intaking structure built in developing one kind use for diesel engine compact-sized, easy to use, can effectively solve
The certainly above problem.
Utility model content
The purpose of this utility model is to provide pre-heating intaking knots built in a kind of use for diesel engine compact-sized, easy to use
Structure realizes diesel engine intake electric heating function to solve in the case where not changing air inlet pipeline.
In order to achieve the above objectives, the technical solution adopted in the utility model is: pre-heating intaking knot built in a kind of use for diesel engine
Structure, comprising: bolt, inlet pipe connection, preheater, gasket, positive stud, cathode bolt, gauze pad, air inlet pipe；Inlet pipe connection
It is connected with preheater by clearance fit, is provided with corresponding mounting hole after inlet pipe connection and preheater cooperation, and pass through anode
Stud, gasket and cathode are bolted；It is provided with corresponding mounting hole on inlet pipe connection and air inlet pipe, and passes through bolt and gauze pad
It is attached.
On the inner wall of inlet pipe connection, it is provided with preheater positive terminal hole and preheater negative terminal hole.
Positive terminal hole boss and negative terminal hole boss are provided on the lateral surface of inlet pipe connection.
Sebific duct connection boss is provided on the front end face of inlet pipe connection.
Inlet pipe connection fixed hole is provided on the rear end face of inlet pipe connection.
The beneficial effect that the utility model obtains afterwards by adopting the above technical scheme is: the utility model is compact-sized, convenient
Installation and maintenance, it is safe and reliable.By preheater and inlet pipe connection clearance fit, the fresh air of entrance is added
Heat efficiently solves the problems, such as the low temperature hard-to-start of diesel engine.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and embodiments, it is to be understood that the guarantor of the utility model
Shield range is not limited by present embodiment.
As shown in Fig. 1 ~ 3, inlet pipe connection inner wall 2-1 is provided on the inlet pipe connection 2 in the utility model, air inlet connects
Preheater positive terminal hole 2-11 and preheater negative terminal hole 2-12, inlet pipe connection outside are provided in nozzle inner wall 2-1
It is provided with positive terminal hole boss 2-21 and negative terminal hole boss 2-22 on the 2-2 of face, is arranged on inlet pipe connection front end face 2-3
There is sebific duct to connect boss 2-31, is provided with inlet pipe connection fixed hole 2-41 on inlet pipe connection rear end face 2-4.
Inlet pipe connection 2 is connected with preheater 3 by clearance fit, is provided with after inlet pipe connection 2 and the cooperation of preheater 3
Corresponding mounting hole, is connected by positive stud 5, gasket 4 and cathode bolt 6；It is provided on inlet pipe connection 2 and air inlet pipe 8 pair
Mounting hole is answered, is attached by bolt 1 and gauze pad 7.It thus can be by built-in preheater, to the new of entrance inlet pipe connection
Fresh air is preheated before entering engine chamber.Part diesel engine is solved because pipeline limitation is not available air inlet electricity
The problem of pre- heat function, to solve the problems, such as diesel engine low temperature hard-to-start.
Situation described in this embodiment is not limited in practical application, all do not depart from the utility model in essence content
Technical solution and improvement, should all fall into the scope of the claims of the utility model.
