Abstract

The utility model relates to a water-cooled preheater of a vehicle, which belongs to preheating devices for vehicle engines. The utility model comprises a communicating pipe, a valve, a filter, a heater, a water pump and a return-off valve. The valve, the filter, the heater and the water pump are arranged on the communicating pipe in turn, and the two ends of the communicating pipe are respectively connected and communicated with the water inlet pipe and the water outlet pipe of the water-cooled system of a vehicle engine. The return-off valve is arranged on the water inlet pipe of the water-cooled system of the vehicle engine, and the heater and the water pump are connected with an external 220v power supply. The utility model can quickly cause the vehicle engine in low temperature to quickly obtain normal starting temperature, the cylinder abrasion is reduced, and the service life of the engine is prolonged.

Description

Vehicle water-cooled preheater

The utility model belongs to a kind of Preheating unit of motor car engine.

North cold weather, winter, the cold starting of automobile was more serious to the wearing and tearing of engine system.Put down in writing according to interrelated data: automobile starts the wear extent that wearing and tearing in the cylinder when reaching 60～80 ℃ to engine temperature are equivalent to 30 to 40 kilometers of cruisings in the time of 5 ℃.The wearing and tearing of cylinder have 50% to be to occur in the start-up course approximately.In the winter of northern frore area, the wearing and tearing of engine start are just more serious, particularly are the vehicle of fuel with diesel oil, can not start, just roasting, boiling hot with hot water with fire, even the personnel selection of opening the throttle pushes away, this not only wastes fuel, has increased environmental pollution, and very dangerous.

The purpose of this utility model is at the problems referred to above, and a kind of vehicle water-cooled preheater that solves the automobile cold start problem is provided.

As everyone knows, not overheated in the course of the work in order to make motor car engine, adopt the way (except that air-cooled) of Forced water cooling usually, constituent comprises radiator, water jacket, pump.Radiator and water jacket are communicated with by intake pipe and outlet pipe.Temperature raises in the cylinder operation process, and by the water cooling in the water jacket, the water temperature in the water jacket raises, be pumped to radiator heat-dissipation after, get back to again in the water jacket, the Forced water cooling of circulation realization motor like this is in order to avoid cylinder is damaged because of overheated.

Vehicle water-cooled preheater comprises connecting tube, valve, heater, water pump and returns disconnected valve.Valve, heater and water pump were successively set on connecting tube, and the two ends of connecting tube are connected with outlet pipe with the intake pipe of motor car engine water cooling system respectively, and communicate.Returning disconnected valve is arranged on the intake pipe.Heater and water pump connect the 220V power supply.

Before starting vehicle, earlier connecting valve is opened, to return disconnected valve closes, connect the 220V power supply, at this moment heater and water pump are worked simultaneously, the antifreeze liquid of heating is sent into water jacket, and the water that has been heated, is so continued to heat and circulation is preheated cylinder at the top of cylinder with circulate on every side by water jacket.Because the water that has been heated is without radiator, heat is difficult for being scattered and disappeared, and cylinder can reach the preference temperature of normal starting very soon.When piloting engine, cut off the 220V power supply earlier.After the engine start, antifreeze low viscous lubricant oil can be adsorbed on the hot cylinder wall, forms oil film, and can be rapidly heated, because cylinder body is warm, fuel oil energy atomizes effectively, thereby guarantees the normal operation and the acceleration of motor.After the engine start, must will return disconnected valve and open at leisure, recover the cooling system proper functioning.

The utility model is not only simple in structure, and is easy to use, and the preheating speed is fast, fuel saving, and can reduce the wearing and tearing of motor, improve the working life of motor.

Fig. 1 is an a kind of embodiment's of the present utility model structural representation.The utility model is described in further detail below in conjunction with accompanying drawing.

The utility model, promptly vehicle water-cooled preheater is made up of connecting tube 1, lead 7 and Preheating unit, and Preheating unit is made up of valve 2, filter 3, heater 4, water pump 5, time disconnected valve 6 and lead 7.Valve 2, filter 3, heater 4, water pump 5 were successively set on connecting tube 1, and the end of connecting tube 1 is connected with the intake pipe 8 of the constituent of motor car engine and communicates, and the other end is connected with the outlet pipe 9 of the constituent of motor car engine and communicates.Returning disconnected valve 6 is arranged on the intake pipe 8.Heater 4 and water pump 5 uses the 220V power supplys, i.e. lead 7 plugs 11, and plug 11 can be inserted in the 220V power socket.Heater 4 has temperature control function, when being heated liquid medium temperature and reaching setting value, just can cut off the electricity supply automatically, stops liquid medium being heated.

When start-uping a car at low temperatures, at first close back disconnected valve 6, cut off and lead to the loop of radiator 10 in the automobile water-cooling system.Open valve 2 again, connect the 220V power supply, heater 4 and water pump 5 are worked simultaneously, are heated liquid medium (antifreeze liquid, water) and enter in the heater 4 through valve 2 and filter 3, and heating back pumps in the water jacket of motor by water pump 5, make the cylinder preheating, when cylinder is preheated to the normal starting temperature as 80 ℃, automatically cut off the 220V power supply, the driver can pilot engine, behind the engine ignition, slowly open back disconnected valve 6, make constituent recover proper functioning.

Claims

1, vehicle water-cooled preheater, comprise connecting tube (1), lead (7) and Preheating unit, it is characterized in that described Preheating unit is by valve (2), filter (3), heater (4), water pump (5) with return disconnected valve (6) and form, valve (2), filter (3), heater (4), water pump (5) are successively set on connecting tube on (1), the two ends of connecting tube (1) are connected with outlet pipe (9) with the intake pipe (8) of motor car engine constituent respectively and communicate, and return disconnected valve (6) and are arranged on the intake pipe (8).
