Description
Technical field
The utility model relates to a kind of auto parts and components, is specifically related to a kind of compound air inlet heating device that is used for diesel engine.
Background technique
When cold area and severe cold season are piloted engine, because engine oil viscosity increases, the starting resistance square also will increase; While fuel gasification decreased performance, the service behaviour of storage battery reduces, and makes the engine start difficulty.The automobile and the motor industry development of China at present is rapid, and improving fuel engine starting performance at low temperatures is an important technological problems that must solve.Fuel engine especially diesel engine is subjected to the influence of environment to cause starting difficulty very greatly under the low temperature in the winter time, even can't start at a lower temperature at all.For head it off, auxiliary devices that can improve the fuel fire condition and reduce starting torque more commonly used are as glow plug, intake air preheater, starting preheater boiler, starting fluid injector and starting decompressor etc.Regrettably these measures are under utmost point cryogenic conditions, and are still not very good.
The auxiliary starting device that the utility model proposed can make diesel engine starting smoothly more than ambient temperature-35 ℃; For special severe cold area and special vehicle (as military vehicle etc.), then can guarantee the starting rapidly more than ambient temperature-41 ℃ of diesel engine and car load.
Summary of the invention
The purpose of this utility model is in order to solve the reliable rapidly problem of starting successfully of under-41 ℃ condition of ultralow temperature diesel engine, provides a kind of and has that compact structure, installation and maintenance are easy, the diesel engine composite efficient air inlet heating device of low-temperature cool starting good reliability.
Below in conjunction with accompanying drawing know-why of the present utility model and structure are described: the compound air inlet heating device of use for diesel engine has: cylinder head, conductive plate, charge heating plug, sealing gasket, grid air heater, bolt, rubber seal cushion rubber, constant voltage stable state suction tude, air inlet tube etc.The top of cylinder head intake duct side is provided with the charge heating plug, and the charge heating plug connects together by conductive plate and is installed on the cylinder head.Cylinder head intake duct side is equipped with the grid air heater, grid air heater both sides are equipped with sealing gasket and rubber seal cushion rubber respectively, by bolt that intake duct end cap and grid air heater, sealing gasket and rubber seal cushion rubber is fastening, the intake duct end cap is connected to constant voltage stable state suction tude.Be connected with bolt in the flange mode between constant voltage stable state suction tude and the suction tude joint.Described constant voltage stable state suction tude does not design intake manifold separately as an air inlet voltage stabilizing cavity, and the inlet flange side is provided with the annular groove that is coated with sealer.Its cardinal principle is: the charge heating plug is installed on the cylinder head by conductive plate, is provided with a grid heater simultaneously between cylinder cover for diesel engine and constant voltage stable state suction tude, and the storage battery of car load is as the power supply of heater plug and grid heater.By the charge heating plug air in the cylinder of diesel engine is preheated; By the grid air heater air-flow in the constant voltage stable state suction tude is heated, constitute dual compound preheating air inlet.Under low temperature state, during engine start, determine by pre-heat controller on the car load and preheating switch whether Preheating unit enters compound heating, or an independent heated condition in two heating systems.When ambient temperature more than-35 ℃ the time, start charge heating separately and fill in capable preheating; When ambient temperature during at-35 ℃ to-41 ℃, charge heating plug and grid air heater are worked simultaneously.Under heated condition,, guaranteed diesel engine starting rapidly under-41 ℃ cryogenic conditions because interior gas of cylinder of diesel engine and extraneous current are heated simultaneously fully through the air-flow of grid air heater.Because compound Preheating unit directly heats cylinder interior, so its efficient is very high.
Characteristics of the present utility model and beneficial effect are: stable working is soft during the cold-starting motor, has effectively reduced the wearing and tearing of engine body, has prolonged motor working life in fuel saving.Test shows, and is respond well to the cold starting of diesel engine and car load under-41 ℃ cryogenic conditions, and the storage battery that the composite efficient air inlet heating device can use automobile itself is easy to use as power supply, installs simple, safe and reliable.

Embodiment
Below in conjunction with accompanying drawing structure of the present utility model is described further: structurally: the top of cylinder head 1 intake duct side is provided with charge heating plug 3, and the tapped hole that heater plug is installed communicates with cylinder.Charge heating plug 3 links together by conductive plate 2, is installed on (as Fig. 1) on the cylinder head 1.Cylinder head intake duct side is equipped with grid air heater 5, and grid air heater both sides are equipped with sealing gasket 4 and rubber seal cushion rubber 7 respectively, and is by bolt 6 that intake duct end cap 11 is fastening with grid air heater 5, sealing gasket 4 and rubber seal cushion rubber 7.Intake duct end cap 11 is connected to constant voltage stable state suction tude 8, is connected (as Fig. 2) in the flange mode with bolt 9 between constant voltage stable state suction tude and the suction tude joint 10.Constant voltage stable state suction tude 8 does not design intake manifold separately as an air inlet voltage stabilizing cavity, and the inlet flange side is provided with the annular groove that is coated with sealer.
Fig. 2 is the schematic representation of the utility model decomposition texture, and the air inlet side of present embodiment cylinder head is provided with 4 intake ducts, so the intake duct top of cylinder head is provided with 4 charge heating plugs, illustrated conductive plate and charge heating plug are the states when being in not with assembling.Conductive plate links together 4 charge heating plugs, and the width of grid air heater is 23.2 ± 0.2mm.When ambient temperature more than-35 ℃ the time, 4 charge heatings covering of starting cylinder are filled in capable preheating separately; When ambient temperature is between-35 ℃ to-41 ℃, charge heating plug and grid air heater are worked simultaneously, earlier to charge heating plug heating 35 seconds, start the grid air heater then, the power supply of grid air heater is from the storage battery on the car load, this moment, charge heating plug and grid air heater co-operation can be started diesel engine when the charge heating plug is heated to 70 seconds.Under heated condition, the air-flow of the gas and the grid air heater of flowing through has obtained sufficient heating simultaneously in the cylinder of diesel engine, thereby has guaranteed diesel engine starting rapidly under-41 ℃ cryogenic conditions.The compound air inlet heating device of this diesel engine is mainly used in auxiliary diesel and starts under ultralow temperature, to improve the cold starting performance of diesel engine.
