Description

Cold start preheater of external power type for engine

The invention belongs to the Preheating unit that a kind of external 220 volts of power supplys start the cold in the winter time machine of various motors.

Existing various motors, particularly diesel engine are in the winter time during subzero low temperature, because water temperature is low around the cylinder barrel, igniting outburst condition is poor, oil temperature is low, viscosity is big, insufficient lubrication, the Starter load increases, and can not reach effective rotating speed, and ambient temperature is low, reasons such as air inlet atomization badness are very difficult to cold machine is started.The most of regional winter temperature of China is all subzero below-10 ℃, and except that the motor that is parked in insulation workshop or garage, all the other are all had to adopt when shutting down and discharge water; add hot water during startup in a large number, the roasting oil of the fire end,, boiling water waters mixture pipe; or half way up the mountain stops the startup of slide car.Both inconvenient, dangerous again, operation labor intensity is big.Though there is the part diesel engine that the heater plug device is housed, as be installed in the heater plug that 375 types, three cylinder diesel engine oil nozzle roots on the black panther transport vehicle are produced in Shandong, also can only heat the oil spout part, still can't resolve air inlet, cooling water, the low temperature problem of machine oil, and, because heater plug needs long-time heavy-current discharge, battery tension is descended, further reduced the useful horsepower of Starter, shortened the working life of storage battery and Starter, so, under subzero-10 ℃ environmental conditions, do not add hot water, still can not normally start.

Purpose of the present invention is exactly at the problems referred to above, a kind of electrothermal part that utilizes external 220 volts of power supplys is provided, the heating air inlet pipe, cooling water around the cylinder barrel and oil end machine oil, the Preheating unit that motor can normal cold machine under the condition below the ambient temperature-10 ℃ be started.

The purpose of this utility model is achieved in that

The utility model comprises electric heating element, engine oil under casing, thermostat, mixture pipe, it is characterized in that: little water tank is being installed near engine oil under casing bottom, be inserted with electric heating element in the little water tank, little water tank is connected into and out of cooling nozzle with motor with two pipelines; Electric heating element is installed on mixture pipe.

---little water tank bottom two ends respectively have a groove, respectively insert an electric heating element in each groove.

The electric heating element that the present invention has adopted external 220V mains supply to connect seal arrangement is housed inserts near in the additional little water tank of installing at the bottom of the engine oil, the machine oil at the bottom of the cooling water that is added with antifreeze liquid and the engine oil of directly heating, utilize the difference of height of heat, cold water proportion difference and little water tank and cylinder body, heat to starting cylinder barrel to carry out hot water circuit on every side by bypass road junction and the little water outlet of water tank that is installed in the thermostat bottom and two heat-resistant rubber hose pipelines that are installed on motor cock of water drain and the little water tank inlet.Simultaneously, additional one group of electric heating element heating air inlet on the air inlet mixture pipe.Making motor-10---under 35 ℃ of temperature, preheating 10-30 minute, power consumption 0.5-1.5 degree normally started.

Advantage of the present invention has: 1, at-10 ℃---under 35 ℃ the temperature, be added with the engine shutdown of antifreeze liquid after, though dead time length, need not discharge water, all can normally start in 10-30 minute in energising; 2, external civil power 220V power supply, various places are easy to use, and vehicle only need have one to be furnished with 2.5 squares 20 meters waterproof flexible glue lines of common power plug and to get final product; 3, easy to operate, only need to connect power supply; 4, the present invention utilizes thermostat 40 ℃ of performances of not opening below-50 ℃, and circulating hot water and engine radiator cooling water are opened circuit, 1/3rd of the whole engine cooling water of only having heated, the i.e. cooling water of the first half around the cylinder barrel.So quick heating is saved the energy; 5, electric heating element adopts the mica resistance line sheet that sell in market, and safe and reliable, long service life is easily purchased easily and changed; 6, easy for installation, sieve silk was fixed at the bottom of additional little water tank utilized former machine oil, Circulation pipe adopts the automotive fan heater sebific duct, do not need motor is transformed, additional electrical thermoelement on the air inlet mixture pipe makes semi-circular fixing getting final product with tinsel, all can conveniently install on the mixture pipe of various motors; 7, machine oil is heated under the biography temperature of little water tank simultaneously, and viscosity is low, and lubricating condition strengthens, and has alleviated and has started load, has shortened discharge time, has saved the limited electric energy of storage battery, protects and prolonged the working life of Starter storage battery.

Below in conjunction with accompanying drawing embodiments of the invention are further described.

Fig. 1 is a working principle schematic representation of the present invention:

Additional little water tank 10 by common iron sheet according to engine oil at the bottom of the size of 7 one sides make the hollow water-tight can 10 of a rectangle, and at a water intake 13 and water outlet 9 joints of respectively being welded up and down, do two watertight metal troughs 17 slotting can two ends that are welded in according to required electric heating element size weldering, tightly be inserted into electric heating element 18 in the metal trough, with lead 16 with two electric heating elements be installed on the engine charge mixture pipe 5 with fixing electric heating element 6 parallel connections of semi-circular sheet metal, by switch insurance 14 and Three-hole socket 15 and external 220V power connection.Cooling water in the little water tank is heated, cooling water after heating enters cylinder body 8 tops by the sebific duct 4 that is connected at the bypass road junction 3 of little water outlet of water tank and thermostat bottom, the cooling water that inferior part of the cylinder block is not heated replenishes into little water tank continuation heating by the water intake connecting pipe 12 of motor cock of water drain 11 and little water tank, around the motor cylinder barrel, particularly upper point prevails and sends out the continuous circular heating in working area, simultaneously, because thermostat 2 is in closed condition this moment, make to add hot water and open circuit in radiator 1 water route.At this moment, 7 machine oil are heated under the heat transmission of little water tank near face at the bottom of the engine oil, electric heating element additional on the air inlet mixer tube heats mixture pipe synchronously, air inlet, machine oil, cylinder barrel cooling water on every side are raised to more than 0 ℃ very soon, after engine start condition abundance, just can normally start.Producing installation testing on the black panther agricultural transportation vehicle 375 types three cylinder diesel engine through the present invention in Shandong, is-10 ℃ at temperature---under 30 ℃, switched on 10-30 minute, and power consumption 0.5-0.7 degree, the one-shot success rate is 95%, the restarting success rate is 100%.
