Abstract
The utility model belongs to the field of engine preheating, and particularly discloses a cold start preheating device of a heavy oil engine, which includes a storage battery, a preheating switch, a thick film semiconductor infrared heating element, a temperature sensor and a temperature indicator, wherein the heating element is adhered to the cylinder cover of the engine. The heat generated by the heating element through the electrical energy of the storage battery is transmitted into a combustion chamber through the cylinder cover; the temperature sensor is used for collecting the temperature of the cylinder cover and displaying through the temperature indicator; and when the set temperature is reached, the preheating switch is closed, and the preheating of the engine is accomplished. The cold start preheating device of the heavy oil engine can quickly heat the cylinder cover during the cold start of the engine and accelerate fuel atomization, thereby effectively overcoming the difficult problem of cold start of the heavy oil engine under low temperature.
Description
Technical field
The utility model relates to a kind of Preheating unit that is used for the heavy oil engine cold starting, belongs to the engine warming up field.
Background technique
Under the lower situation of ambient temperature, heavy oil engine is when cold starting, and the burning room temperature is lower, the phenomenon that fuel oil is difficult for atomizing and exists secondary to condense.At present, existing engine preheating system mainly adopts the method for charge heating and fuel-firing preheating, and heating material mainly is electrical heating wire and glow plug.Yet charge heating and fuel-firing preheating efficient are lower, and the power consumption of electrical heating wire and glow plug is big, the efficiency of heating surface is low, speed is slow, working life is short, heating the time has naked light, Security is relatively poor.
The model utility content
The defective that the utility model exists to existing technology, and a kind of heavy oil engine Preheating unit through the heated engine cylinder cap is proposed.
This device comprises storage battery, preheating switch, heater band, temperature transducer and temperature indicator; Wherein: heater band sticks on the cylinder cap of motor; Storage battery connects heater band through preheating switch; Temperature transducer is arranged at the spark plug place of motor, and temperature transducer is connected with temperature indicator.
Said storage battery also connects voltmeter, and voltmeter is used to monitor the voltage of storage battery.
Preferably, heater band adopts thick film semiconducting infrared heating sheet.
Technique effect:
1, the cylinder cap of the direct heated engine of the utility model; Make heat be delivered to the firing chamber effectively and heat inflammable mixture; Can make the temperature of inflammable mixture reach kindling temperature in the short period of time, effectively improve the starting performance of heavy oil engine under cryogenic conditions.
2, adopt thick film semiconducting infrared heating sheet, few to the heat diffusion area influence of cylinder cap, the flames of anger when heating, safe and reliable, the efficiency of heating surface is high.
3, effectively reduce the discharging of motor HC (hydrocarbon) when cold starting.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Label title among the figure: 1, storage battery; 2, voltmeter; 3, preheating switch; 4, engine chamber; 5, heater band; 6, temperature transducer; 7, temperature indicator.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The structure of the utility model device is as shown in Figure 1, specifically comprises storage battery 1, voltmeter 2, preheating switch 3, heater band 5, temperature transducer 6 and temperature indicator 7.
When engine warming up, open preheating switch 3, storage battery 1 gives heater band 5 energisings; Heater band 5 is converted into heat energy with electric energy, and heat energy is delivered in the firing chamber 4 through cylinder cap, the inflammable mixture in the heating flame chamber 4; Prevent that the fuel oil secondary from condensing, and make mixed gas reach kindling temperature.Temperature indicator 7 demonstrates the cylinder cap temperature that temperature transducer 6 is gathered, and when reaching setting temperature, closes preheating switch 3, and heater band 5 and storage battery 1 are broken off, and accomplishes the engine warming up process.
