Abstract
A cold start rapid heating system of an automobile electric spray engine relates to an automobile engine system, and comprises an oil atomizer, an intake manifold and a rapid heater, wherein, the rapid heater is composed of at least a PTC heat sheet and a heat insulation plate which is arranged below the PTC heating sheet; the rapid heater is arranged on the wall of the intake manifold opposite to a nozzle of the oil atomizer, and the input end of the PTC heating sheet is connected with an engine controller. The cold start rapid heating system makes fuel oil of the oil atomizer be properly jetted at the position of the PTC heating sheet, and the atomized fuel oil is absolutely further vaporized, thereby the atomization effect of spraying fuel oil is favorable, the engine can be rapidly started at the condition of low temperature, and the quality of exhaust gas is improved to meet the discharge standard of Europe IV. In addition, the rapid heating system also has the advantages of improvement of automobile power performance, simple structure and low cost.
Description
Technical field:
The utility model relates to a kind of automobile engine system, particularly a kind of automotive electric injection engine cold start-up automotive quick-heat system.
Background technique:
Existing electronic fuel injection engine system is when low-temperature condition, the problem of ubiquity engine start difficulty, this is because when engine ignition starts, the fuel-oil atmozation that oil sprayer sprays, but the atomizing effect of this moment is because the granularity of the low atomizing of temperature is big, make that fuel oil can not perfect combustion, thereby produce a large amount of harmful gases, cause automobile starting difficulty, discharge amount to exceed standard and can influence life-span of vehicle exhaust filtrating equipment ternary Cuiization device, this also is the basic reason that present homemade electro jet car can't reach Europe IV emission standard.Engine preheating system miscellaneous is also arranged at present,, all be not suitable for existing electronic fuel injection engine system though this class Preheating unit can be used to solve the problem of conventional engine system start-up difficulty under the low temperature; And these Preheating units all are that whole intake manifold pipeline to motor heats, therefore the whole steam fogs of fuel oil that are difficult to oil sprayer is gushed out melt, thereby can not fundamentally solve electronic fuel injection engine system start-up difficulty, discharge amount exceeds standard, influences the vehicle exhaust filtrating equipment ternary problem in Cuiization device life-span.
The model utility content:
The technical problems to be solved in the utility model is: a kind of automotive electric injection engine cold start-up automotive quick-heat system is provided, this automotive quick-heat system can solve EFI formula motor under normal temperature or low-temperature condition, the atomizing effect of injected fuel is poor, the problem of startup difficulty, thereby improves the exhaust emissions quality of EFI formula motor.
The technological scheme that solves the problems of the technologies described above is: a kind of automotive electric injection engine cold start-up automotive quick-heat system, comprise oil sprayer, intake manifold, rapid heater, described rapid heater is by a slice pottery PTC (abbreviation of Positive Temperature Coefficient at least, the meaning is positive temperature coefficient, very big semi-conducting material or the components and parts of general reference positive temperature coefficient) thermistor heater band (hereinafter to be referred as the PTC heater band) and thermal baffle are formed, and thermal baffle is positioned at the below of PTC heater band; This rapid heater is installed on the intake manifold tube wall of fuel injector nozzle tip, and the input end of PTC heater band is connected with engine controller.
Further technological scheme of the present utility model is: described PTC heater band fuses by the mode that flexibly connects or fixedly connected with thermal baffle.
Owing to adopt said structure, the automotive electric injection engine cold start-up automotive quick-heat system of the utility model is compared with existing electronic fuel injection engine system, has following beneficial effect:
1, the atomizing effect of injected fuel is good, and is still capable of fast starting under low-temperature condition:
Because the utility model includes one with the rapid heater of PTC heater band as heater element, this rapid heater is installed on the intake manifold tube wall of fuel injector nozzle tip, and the PTC heater band is controlled by connected engine controller, therefore when engine ignition starts, the atomized fuel of oil sprayer just in time all is ejected into the PTC heater band position of rapid heater, and this moment, the PTC heater band can generate heat under the control of engine controller moment, make hundred-percent atomized fuel further be evaporated atomizing, therefore the fuel oil mixture burning that enters the engine combustion cylinder is more complete, more abundant, thereby reduce the generation of harmful gas, this electronic fuel injection engine system still can be started under low-temperature condition fast, but also can improve the quality of tail gas, make its emission standard that reaches Europe IV, also can prolong simultaneously the life-span of vehicle exhaust filtrating equipment ternary Cuiization device.
2, can improve the power performance of automobile:
Because this automotive quick-heat system has increased a rapid heater, makes the fuel oil mixture of deflagrating jar burn more fully, therefore under the condition the same with oil mass, the power performance of automobile is improved greatly.
3, simple in structure, cost of production is low.
Because the structure of this automotive quick-heat system is compared with the structure of the electronic fuel injection engine system of routine, just increased a rapid heater, and this rapid heater only is made up of PTC heater band and thermal baffle, and therefore structure of the present utility model is very simple, and its cost of production is also lower.
Below, the technical characteristics to the automotive electric injection engine cold start-up automotive quick-heat system of the utility model is further described in conjunction with the accompanying drawings and embodiments.
