Abstract

The utility model relates to a water-cooling engine preheater, which is composed of a machine case, an exhaust pipe, and a silencer, wherein, the machine case is provided with a blower, a water pump, an oil pump and a burner. The utility model utilizes the oil pump and the blower to pump the gasoline in an oil tank and outside air into the burner in order to combust and heat the engine cooling water which is pumped in a burner water jacket by the water pump, and thus, the function of preheating the engine to start smoothly is achieved. The utility model has the advantages of compact structure, flexible operation, great convenience, etc.

Description

Water-cooling engine preheater

The utility model belongs to the water-cooled engine pre-heating device.

Before the present utility model, the water-cooled engine actuating ratio of winter or cold area vehicle or other use occasion is difficulty, generally adopts to add hot water or shake the mode of starting in motor to be solved.This just brings a lot of troubles to the driver, and effect is also undesirable, and under no hot water service situation, engine start is just more difficult.

The purpose of this utility model is that a kind of preheater that is applicable to winter or cold area water-cooled motor will be provided, and motor can be started under low temperature environment smoothly.

The design of this model utility is such: in the preheater cabinet, is equipped with and utilizes water pump, oil pump and the blower of DC electrical source for power, and a burner.Water pump pumps into in-engine cooling water in the water jacket of burner; Oil pump pumps into fuel oil (gasoline), blower with air in the firing chamber of burner simultaneously, the water in the burner for heating water jacket of burning back.Water after the heating is got back to again in the motor, plays warm-up the engine, makes it the effect of starting smoothly.

An embodiment below in conjunction with this model utility of description of drawings.

Fig. 1 is the stereogram of this preheater, and wherein 1 is cabinet, the 2nd, and outlet pipe, the terminal of outlet pipe 2 is connected to silencing apparatus 3.

Fig. 2 is the cut-away view of preheater, and wherein 6 is burners, and Fig. 3 is the cut-away view of burner 6.

12 is water pumps, the 13rd in Fig. 2, and oil pump is installed on the base plate of cabinet 1, and blower 5 and spark coil 4 also are housed on the cabinet 1.The effect of water pump 12 is by intake pipe 10, and in outlet pipe 11 pumped into the water jacket 21 of burner 6, water jacket 21 was equipped with temperature controller 8 with in-engine cooling water.The effect of oil pump is by oil inlet pipe 14, with the gasoline in the fuel tank in oil outlet tube 15 pumps into the firing chamber 19 of burner 6, simultaneously blower 5 with air in airduct 7 pumps into firing chamber 19.Solenoid valve 16, oil injecting nozzle 17 and spark plug 18 are equipped with in 19 tops, firing chamber.

During work, the petrol tank on oil inlet pipe 14 and use scene or the vehicle is connected, intake pipe 10 and engine cooling water pipe are connected, and connect DC electrical source then, and water pump 12, blower 5, oil pump 13 are worked simultaneously.Water pump 12 is by intake pipe 10, outlet pipe 11 pumps into in-engine water in the water jacket 21 of burner 6, this moment is under the effect of solenoid valve 16, oil injecting nozzle 17 is opened, oil pump 13 is by oil inlet pipe 14, gasoline in the petrol tank is pumped into the firing chamber 19 of burner 6 and mixed through the air that airduct 7 pumps into firing chamber 19 by blower 5 through oil outlet tube 15.Spark plug 18 will mix the gas ignition under the effect of spark coil 4, the water in the heating water jacket 21.The effect of helical blade 20 is the flow velocitys that slow down hot gas, improves heats.Waste gas through export 22, outlet pipe 2, silencing apparatus 3 discharge.Water after the heating enters in the motor through hot-water line 9, and warm-up the engine so circulates.When water temperature when a certain setting temperature, temperature controller 8 actions are cut off the electricity supply, start function to start smoothly this moment.
