Abstract
The utility model relates to a preheating device for starting internal combustion engines, which is suitable for areas with cold winters, which is composed of an oil sucking pipe, an engine oil heater, a heating coil, an oil outlet pipe, a one-way valve, an engine oil pump, and a motor. The utility model has a basic principle that engine oil in each lubricating oil pipe in an internal combustion engine is heated to rise the temperature of each lubricating face of the internal combustion engine to preheat the internal combustion engine. Only a general 220 volts alternating current can be used as a heat source. The utility model is a preheating device for starting internal combustion engines with the advantage of wide purpose.
Description
The utility model belongs to technical field of internal combustion engines, is a kind of internal-combustion engine cold-starting preheater specifically.
In the prior art, internal-combustion engine starting difficulty phenomenon under low temperature environment is ubiquitous.One of reason that causes internal-combustion engine cold-starting difficulty is because cylinder cap, cylinder liner, piston temperature are low, the heat of pressurized gas in a large amount of absorption firing chambers, and temperature can not reach combustion temperature compressing at the end to make pressurized gas; The 2nd, cause cutting-in speed not enough because starting resistance is excessive.In these two reasons starting resistance excessive be the main cause that causes internal-combustion engine cold starting performance difference.And cause the excessive main cause of starting resistance to be because under cryogenic conditions, the engine oil viscosity that is trapped on each parts attrition surface of internal-combustion engine is excessive, the motion frictional resistance and the oil sump engine oil viscosity interior and that oil leab is interior that have strengthened each parts attrition surface are excessive, have increased the flow resistance of machine oil in oil leab.In order to reduce the starting resistance that internal-combustion engine produces greatly because of engine oil viscosity under low temperature environment, use diesel engine starting preheater and steam economizer bank to utilize electric heating and steam that the machine oil in the oil sump is carried out preheating at present on the diesel engine, but these two kinds of devices can only reduce the viscosity of the low shell inner engine oil of oil, and can not reduce in the oil leab and each parts rubbing surface on the viscosity of machine oil, so can not reduce the starting resistance of internal-combustion engine effectively.
The purpose of this utility model be for internal-combustion engine in the winter time cold area can start easily a kind of internal combustion engine start preheater is provided, improve the starting performance of internal-combustion engine.
For improving the scarce limit of original technology, the utility model has provided a kind of internal-combustion engine cold-starting preheater.This equipment is made up of motor, oil pump, lube oil heater, fuel sucking pipe, one-way valve, oil outlet tube, fuel sucking pipe electrically-heated coil, lube oil heater electrically-heated coil.Be fixed on the internal-combustion engine with support during use, an end of fuel sucking pipe communicates with the low shell of oil, and the other end and lube oil heater filler opening join, and fuel sucking pipe machine oil electrically-heated coil and lube oil heater electrically-heated coil are contained in respectively in fuel sucking pipe and the lube oil heater.The oil outlet of lube oil heater links to each other with oil pump, and single-phase valve is installed on the oil pump oil outlet, and one of oil outlet tube terminates on the single-phase valve, and the other end links to each other with the internal combustion engine lubrication oil duct.Start motor and get final product sucking-off machine oil, can pump into machine oil after the heating.
The technical solution of the utility model is achieved in that a kind of engine starting preheater, is made of motor, oil pump, lube oil heater, machine oil pipe, one-way valve, oil outlet tube, fuel sucking pipe electrically-heated coil, lube oil heater electrically-heated coil; It is characterized in that lube oil heater is built-in with the lube oil heater electrically-heated coil, fuel sucking pipe is equipped with the fuel sucking pipe electrically-heated coil outward.When the need cranking internal combustion engine with the engine starting Preheating unit with being placed on by the internal-combustion engine, the low shell of oil of fuel sucking pipe and internal-combustion engine is linked to each other, turn on the power switch, the machine oil of internal-combustion engine is drawn into is heated in the heater about 70 ℃, again defeated getting back in the internal-combustion engine got final product cranking internal combustion engine.
The utility model has the advantages that: internal-combustion engine cold-starting preheater can effectively reduce the starting resistance of internal-combustion engine under low temperature environment, improves the cold starting performance of internal-combustion engine; Enlarged pre-heat rating,, increased the bulk temperature of internal-combustion engine by only oil preheating also being conducted heat to each running parts simultaneously to internal-combustion engine; Can shorten operation (warming-up) time at internal-combustion engine initial stage, enter working state in advance, save fuel.
Provide one of the present utility model below in conjunction with accompanying drawing and implement 1 fuel sucking pipe heating coil in the illustration, 2 fuel sucking pipes, 3 220 volts of power supplys, 4 lube oil heater shells, 5 lube oil heater electric coils, 6 oil outlet tubes, 7 one-way valves, 8 oil pump, 9 motor, 10 220 power supplys.Be fixed on the internal-combustion engine with support during use, an end of fuel sucking pipe communicates with the low shell of oil, and the other end and lube oil heater filler opening join, and fuel sucking pipe machine oil electrically-heated coil and heater electrically-heated coil are contained in respectively in fuel sucking pipe and the heater.The oil outlet of lube oil heater links to each other with oil pump, and single-phase valve is installed on the oil pump oil outlet, and one of oil outlet tube terminates on the single-phase valve, and the other end links to each other with the internal combustion engine lubrication oil duct.Start motor and get final product sucking-off machine oil, can pump into machine oil after the heating.
