Description

A kind of motor car engine Preheating unit

The utility model relates to a kind of device that motor car engine is carried out preheating.

At present, the truck of various automobiles, particularly various loadings, because it is bulky, does not generally have the garage to deposit it, if in northern cold winter, automobile in the open the resting period of a specified duration excessively, very difficult when then restarting, both made adding antifreeze liquid, under the lower situation of temperature, also be difficult to start, if start, what condition was good toasts with petrol burner, will not roast with faggot if having; Perhaps behind the automobile stagnation of movement, bleed off cooling liquid, when restarting, add hot water again, so various loading trucks cause very big difficulty in the startup in cold winter to the driver.

The purpose of this utility model provides and a kind ofly makes things convenient for the driver greatly at the cold winter starting automobile of plug motor car engine Preheating unit easily, need not toast.

For reaching above-mentioned purpose, the utility model by the following technical solutions:

The utility model includes a housing, built-in heating pipe, conduit, suction pump, motor, the thermostat of being provided with of housing, wherein, one end of heating pipe is provided with an outlet pipe, other is provided with an air vent, and the other end is provided with a conduit, and the water outlet of this conduit and suction pump links, water inlet UNICOM one water intake of suction pump, suction pump is by driven by motor; Sealing is provided with an electric heating tube in the heating pipe, the outlet pipe of heating pipe is established thermostat, there are two small gaps to communicate on the valve of this thermostat with valve opening, in addition, on valve, offer at least one little water hole, valve is the shutoff valve opening under normal temperature, have only two small gaps and little water hole to communicate with valve opening, in the time of 80～95 ℃, under the effect of suction pump, the cooling liquid small amount of recycled that from two small gaps of thermostatic valve and little water hole, flows, when the cooling liquid in the heating pipe reaches 80～95 ℃, the cooling liquid that flows heats thermostat, makes its valve open, and cooling liquid flows out engine warming up from big valve opening, when coolant temperature is lower than 80～95 ℃, the valve opening of thermostat is closed, and impels electric heating tube to the heating of the cooling liquid in the heating pipe, circulates next time.

Mounting point of the present utility model is such, open the water blocking of engine water temperature induction plug side, with outlet pipe of the present utility model and its UNICOM, the automobile warm-air return pipe is opened a mouth of a river, this mouth of a river and the utility model water intake link, so, heated water circulates in automobile engine cylinder-body under the effect of suction pump in the heating pipe, warm-up the engine, engine start very easy just like this, after the preheating, the ABAP Adapter that will be connected with the utility model is pulled out and is got final product.

Use automobile of the present utility model, when starting in the winter time, need not to toast in various manners, can start sparking easily, easily, give the driver very big convenience.

The utility model will be further described below in conjunction with drawings and Examples:
