Abstract
The utility model discloses a high-efficiency preheating device for starting internal combustion engines, which is composed of a motor (2), an engine oil pump (1), an electric heater (10), an oil sucking pipe (17), oil outlet pipes (7), (8), and an engine oil spraying head (9). The motor (2), the energy oil pump (1) and the electric heater (10) of the utility model form integration. Under the action of the energy oil pump (1), engine oil of an internal combustion engine flows circularly between the internal combustion engine and the electric heater (10) through the oil sucking pipe (17), the oil outlet pipes (7), (8) and the engine oil spraying (9), continuously brings heat generated by the electric heater (10) to the internal combustion engine, and carries out pre-lubrication to the internal combustion engine to make the internal combustion engine achieve the temperature state and the lubricating state of the full-load operating requirements before the internal combustion engine is started.
Description
The utility model belongs to technical field of internal combustion engines, is a kind of high efficiency internal combustion engine starting preheater specifically.
The internal-combustion engine ubiquity the phenomenon of starting difficulty under low temperature environment, the reason one that causes this phenomenon is owing to cylinder head, cylinder liner, and the temperature of piston is low, the heat of pressurized gas in a large amount of absorption firing chambers makes pressurized gas at the end can not reach combustion temperature in compression; The 2nd, because engine oil viscosity is excessive at low temperatures, increased the motion frictional resistance of the flow resistance of machine oil in oil duct and each parts attrition surface, cause that the engine starting resistance is excessive can not to reach cutting-in speed.In order to improve the cold starting performance of internal-combustion engine, use steam preheating pipe and anticipatory electric heater that the machine oil in the oil sump is carried out preheating at present on the internal-combustion engine, but these two kinds of devices can only reduce the viscosity of oil sump inner engine oil, and can not reduce in the oil duct and each parts attrition surface on the viscosity of machine oil, so can not effectively reduce the starting resistance of internal-combustion engine.
Chinese patent specification 99202738.1 disclosed internal-combustion engine cold-starting preheaters are by motor, oil pump, lube oil heater and turnover oil pipe are formed, this preheater is sent to hot machine oil in the internal combustion engine lubrication oil duct with oil pump after heating in the machine oil inhalation machine oil heater in the oil sump with oil pump again, by oil leab hot machine oil is sent on each lubricated parts attrition surface, though this preheater can reduce in the oil leab and the engine oil viscosity on the parts attrition surface, reduce starting resistance, but can not be to cylinder head, cylinder liner and piston preheating are so can not improve the cold starting performance of internal-combustion engine fully; Because the cooling liquid in piston, cylinder head, cylinder block, the cylinder liner does not obtain preheating, the temperature that does not reach the running at full capacity requirement will lean on the heat of internal-combustion engine self running no load generation to come above-mentioned parts preheating, when finishing this warm, not only can cause heavy wear to internal-combustion engine, and wasted a large amount of fuel, also environment has been caused serious tail gas and noise pollution.It is not compact that this preheater of while also exists structure, and the lube oil heater heat exchange is slow, and the heat energy utilization rate is low, operates loaded down with trivial details shortcoming.
Purpose of the present utility model provides a kind of high efficiency internal combustion engine starting preheater.This preheater heat exchange is fast, and the heat utilization efficiency height is easy and simple to handle, can make internal-combustion engine starting easily under low temperature environment, and just can reach the temperature and the lubricating status of running at full capacity requirement at prestart.
The technical solution of the utility model is: this device is made up of motor, oil pump, electric heating apparatus, fuel sucking pipe, fuel sucking pipe electrically-heated coil, one-way valve, oil outlet tube and machine oil shower nozzle, oil pump and the coaxial assembling of motor, oil pump is installed on the motor power output terminal end cap, motor terminal covers the organic oil road, oil road one end communicates with the oil pump oil outlet, the other end is equipped with one-way valve, and one-way valve is connected with oil outlet tube.Oil outlet tube divides two-way: the one tunnel is communicated with the internal combustion engine lubrication oil duct, and another road enters internal combustion engines, and the end of pipeline is equipped with the machine oil shower nozzle, and the machine oil shower nozzle can be with oil injection on piston base and cylinder head and cylinder block.Electric heating apparatus is a tubular, and an end is equipped with heating core in the tube, and the other end is a cavity.The filler opening of oil pump communicates with cavity; On the electric heating apparatus gland fuel sucking pipe is housed, electrically-heated coil is arranged in the fuel sucking pipe, the other end of fuel sucking pipe communicates with oil sump.
During use, connect motor, electric heating apparatus and fuel sucking pipe electrically-heated coil power supply, under the effect of oil pump, the machine oil in the oil sump is flowed through by suction and is pressed into oil outlet tube again behind the electric heating apparatus, divides two-way to enter internal combustion engine lubrication oil duct and internal combustion engines.Machine oil is passed to heat to flow back to again behind each lubricated parts and cylinder head, cylinder block, the piston and is entered next warm-up cycle in the oil sump.
The utility model has the advantages that: the heat that can continuously electric heating apparatus be produced carries to internal-combustion engine, the cooling liquid that make the machine oil of internal-combustion engine, respectively turns round in parts, cylinder head, cylinder block, cylinder liner, piston and the water jacket all obtains preheating, and each running parts carried out prelubrication, make internal-combustion engine just reach the operate at full capacity temperature that requires and good lubricating status at prestart.Avoided internal-combustion engine to walk the waste of fuel in the thermal process and to the pollution of environment with to the heavy wear of internal-combustion engine in starting.
Below in conjunction with accompanying drawing the utility model is described in further detail;
Fig. 1 is a structural representation of the present utility model.
As we know from the figure, oil pump 1 is installed on the end cap 3 of motor 2, oil pump 1 and motor 2 coaxial assemblings have oil road 5 on the End cover for motor 3, oil road 5 one ends communicate with oil pump oil outlet 4, one-way valve 6 is housed on the other end, oil outlet tube 7 oil outlet tubes 7 are housed on the one-way valve 6, are a triplate line, and one the tunnel links to each other with oil outlet tube 8, another road is communicated with the internal combustion engine lubrication oil duct, and the end of oil outlet tube 8 is equipped with several machine oil shower nozzles 9.End in the electric heating 10 is equipped with heating core 11, the other end is a cavity 13, organic oil passage 12 in the heating core 11, one end of oil passageway 12 communicates with fuel sucking pipe 17, the other end communicates with electric heating apparatus cavity 13, with gland 14 and sieve bolt 15 electric heating apparatus 10 is fastened on the End cover for motor 3, oil pump 1 is sealed in the cavity 13 of electric heating apparatus 10, the filler opening 16 of oil pump communicates with cavity 13, one end of fuel sucking pipe 17 communicates with oil sump, and the other end communicates with electric heating apparatus 10, and electrically-heated coil 18 is arranged in the fuel sucking pipe 17, among the figure 19 is electrically-heated coil and electric heater power joint, and 20 is the motor power joint.
