Abstract
The auxiliary start unit for car features that a liquefied gas cylinder serially connected with flow regulator, electromagnetic valve and temp-control switch is communicated with gas inlet of engine, electromagnetic valve is controlled by ignition switch, and a light hydrocarbon gas filling system is controlled by both ignition switch and engine temp. In the winter, light hydrocarbon gas is filled in coming gas of engine for helping ignition.
Description
A kind of auxiliary starting device of automobile, it belongs to a kind of engine accessory power rating, and it is applicable to automobile gasoline or diesel engine, and the cold state that is used to help to solve above-mentioned internal-combustion engine starts.
Motor car engine adopts gasoline or diesel engine more now.Their startup all is to use by battery-driven motor drives to start.In lower and motor off-air time of ambient temperature long after, when beginning to start since fuel gasification or atomize bad, therefore igniting difficulty relatively, will be repeatedly, or the use actuating motor of long period, this has often shortened the life-span of storage battery, also causes the storage battery dead electricity easily.
The objective of the invention is to invent a kind of auxiliary starting device of automobile, it can help to carry out the engine cold state and start shortening starting time or number of times, the consumption of minimizing accumulator electric-quantity, the prolongation life of storage battery.
Structure of the present invention as shown in Figure 1, it has liquefaction gas cartridge 1, it is characterized in that: the equipped at outlet port at liquefaction gas cartridge 1 is in series with flow regulator 2, solenoid valve 3 and temperature detect switch (TDS) 5, join by joint 4 and engine air inlet tube near the motor place afterwards, the electric control end of solenoid valve 3 links to each other with engine ignition switch and by its control.
Accompanying drawing 1 is a structural representation of the present invention.
Working principle of the present invention is as follows:
The present invention has liquefaction gas cartridge 1, it is characterized in that: the equipped at outlet port at liquefaction gas cartridge 1 is in series with flow regulator 2, solenoid valve 3 and temperature detect switch (TDS) 5, join by joint 4 and engine air inlet tube near the motor place afterwards, the electric control end of solenoid valve 3 links to each other with engine ignition switch and by its control.Contain liquid light hydrocarbon in liquefaction gas cartridge 1, it can be the mixture of propane, butane or propane and butane.Equipped at outlet port at liquefaction gas cartridge 1 is in series with flow regulator 2, solenoid valve 3 and temperature detect switch (TDS) 5, join by joint 4 and engine air inlet tube near the motor place at the other end of series connection, the electric control end of solenoid valve 3 links to each other with engine ignition switch and by its control.When the motor proper functioning, ignition switch is in off state, and the also corresponding shutoff of solenoid valve 3 helps the light hydrocarbon gas of igniting usefulness can not enter motor, and the present invention is in off position.When igniting, ignition switch is connected, and makes outside the starting electrical machinery startup, also makes solenoid valve 3 action conductings simultaneously.But when the motor ambient temperature was higher than setting threshold, temperature detect switch (TDS) 5 still was in off state, and the present invention still is in off state.And when the motor ambient temperature is lower than setting threshold, temperature detect switch (TDS) 5 is opened, when starting dynamo-electric fire, because ignition switch makes solenoid valve 3 conductings, the liquefied light hydrocarbon that is stored in the gas cartridge 1 gasifies after flow dontroller 2 is regulated, flow through behind solenoid valve 3 and the temperature detect switch (TDS) 5, enter engine air inlet tube by joint 4, and be inhaled in the cylinder.Because the light hydrocarbon gas burning-point is lower, and is rapid with air mixing, there are not vaporization or atomizing problem, therefore can easily light a fire, quicken starting.
The present invention adopts a kind of light hydrocarbon gas injected system by ignition switch and the dual control of engine temperature.When cold day and motor also are in cold machine state igniting, in engine charge, inject the light-hydrocarbon gas component, solved because the fuel gasification or the bad starting difficulty that produces that atomizes during the cold machine startup of cold day.Can shorten starting time or number of times, thereby reduce accumulator electric-quantity consumption, prolong the life of storage battery.
In the present invention, gas cartridge 1 can use the usual pressure vessel form, and pressure vessel code manufactures and designs, and joins with pipe joint and flow dontroller 2.Also can adopt as the patent No. is the gas tank patent of CNZL93204509.X.The volume of gas cartridge 1 can be between 1～3 liter any value.
In the present invention, flow dontroller 2 can be the cone valve of a manual tune, also can be the membrance valve of manual tune.By the open gap of regulating valve, regulate the output flow velocity of lighter hydrocarbons.
Temperature detect switch (TDS) 5 of the present invention can adopt mechanical double-metal sheet type gas switch, and it is loaded on the motor outer wall.By the distortion of bimetallic strip under different temperatures, open or the closed gas flow passage.Temperature detect switch (TDS) 5 also can adopt the ordinary temp relay to add the form of solenoid valve, and the serviceability temperature relay is controlled solenoid valve.In the present invention, temperature detect switch (TDS) 5 also can be exactly an ordinary temp relay, and it is connected with the automatically controlled end of solenoid valve 3, uses the mode of electric locking, as shown in Figure 2.In igniting and engine temperature when higher, temperature relay is in turnoff state, and ignition switch can not make solenoid valve conduction.Only when engine temperature was lower than threshold value and gets fiery switch ready, temperature relay and ignition switch all were on state, just made solenoid valve 3 conductings, realized adding lighter hydrocarbons and started.
Solenoid valve among the present invention is a general solenoid valve, because flow is little, therefore can use small-sized thin-film electro magnet valve.The present invention can exchange Flow valve 2 and solenoid valve 3 positions, and solenoid valve 3 joins with gas cartridge 1 preceding.
