Description

Low-temp. starting charger for vehicles

The utility model relate to a kind of under low temperature condition the startup charging unit on the automobile, i.e. automobile cold-starting charger.

Automobile engine starting is mainly by storage battery or crank, Bei Fang winter particularly, vapour, diesel engine starting difficulty are particularly outstanding, mainly contain following reason: 1, the lead storage battery winter capacity descends, the output current deficiency, often need that the dismounting storage battery charges and maintain, because starting motor for a long time, make the driver have to be used for hand, long-time fire and way such as bake and start; 2, diesel oil and gasoline atomizes badly when low temperature, also is the reason that causes ignition difficulties, and the driver must open choke and adds rich mixture like this, and is both uneconomical, bad again startup; 3, machine oil viscosity when low temperature increases, and each transmission part friction factor is increased, thereby increase power consumption, is difficult to start, and often the baking heating is unfavorable to machine.

The purpose of this utility model is to overcome the automobile starting difficulty and the above-mentioned defective of existence, a kind of automobile cold-starting charger is provided, loading and unloading when using this charger can exempt to charge in batteries, promptly the ato unit of both can having powered under the situation of 220V source is being arranged, save storage battery and start the energy, but self charges again; Heater section can improve intake temperature, is convenient to fuel-oil atmozation and combustion just, can carry out preheating to lubricant oil again.

To achieve these goals, the utility model adopts following measure: adopting the 220V Ac is electrical source of power, and the direct-current power supply ato unit after the rectification step-down has saved the energy that storage battery power supply starts; Add in the engine air filter ingress simultaneously and put electric heater raising intake temperature, make atomizing fuel oil, light easily; With the dipstick on the electric heating tube replacement fuel tank drain pan that has scale, can indicate lubricants capacity, can carry out preheating to machine oil again.The utility model comprises resistance heater and rectifying and pressure-regulating control circuit part, and power supply passes through K ₁K ₂Link to each other secondary power supply indicator coil, resistive heater coil and rectification coil, the D of being divided into of B with the elementary of transformer B ₁D ₂Constitute current rectifying and wave filtering circuit with capacitor C, and in parallel with the DC circuit of automobile, pass through K again ₅Join with convert charging and startup, by K with storage battery ₃The resistance heater of control places motor filtering ingress, and the heater output conductor is through K ₃Connect heater coil b, another group heater coil c and K ₄The heater lead of control is communicated with.

The utlity model has following advantage;

1, all 220V of having power supplys place just can start various kinds of vehicles fast with this DC electrical source that starts charger output, and outputting current steadily is adjustable, makes the motor can be for a long time or continuous operation.Save storage battery and start power consumption, also can charge storage battery itself.Exempt the storage battery dismounting, saved charging expense and time;

2, owing to install electric heater additional, improve intake temperature, solved the difficult problem of the not enough igniting of fuel-oil atmozation, reduced engine oil viscosity, reduced parts abrasion and motor power consumption, be convenient to igniting;

3, this body is long-pending little, in light weight, can install with car, is applicable to the large, medium and small type vehicle of petrol engine or diesel engine.Use this machine only to need i.e. startup in 2～3 minutes to finish in the winter time.

Doing one below by accompanying drawing in conjunction with embodiment of the present utility model describes in detail.

Fig. 1 is circuit theory diagrams of the present utility model.
