Description
Technical field
The utility model relates to a kind of engine starting system, particularly a kind of engine low-temperature cold starting system of cold area equipment.
Background technique
Engine cold-start is mean engine apart from shutdown last time for some time, begins startup in section's temperature situation consistent with ambient temperature within it.Corresponding with it start in addition thermal starting, be exactly mean engine apart from off time last time soon, section still has in the situation than Gao Yuwen and starts within it.
Engine cold-start specific heat difficulty in starting, particularly very low in ambient temperature, when fuel oil is diesel oil.This is that fuel oil is not easy vaporization because start inside temperature too low during cold start-up.In addition, the lubricant oil of engine interior may be in and solidify or the precipitation state during cold start-up, causes the lubricating condition of each component bad.Therefore, behind the engine cold-start, low-speed running a period of time, progressively heated up in its inside, fuel gasification is very stable, and each component is well lubricated, and then loading.
Cold-starting device is the motor Vehicular heating device that is independent of automobile or engineering machinery vehicle, and its oneself fuel pipe, circuit, burning heater and control gear etc. are arranged.Do not need ato unit to carry out pre-heating temperature elevation to motor car engine and the operator cabin of parking in the winter low temperature cold environment, thoroughly eliminate the cold start-up wearing and tearing of automobile.Its working principle is to utilize the storage battery of this car and fuel tank to come moment power supply and a small amount of fuel feeding, and comes heated engine circulating water and then engine thermal is started by the heat that burns gasoline produces, and operator cabin is heated up.
Chinese invention patent CN102359429 discloses a kind of engine low-temperature cold starting system, comprise for from the pump of fuel tank oil suction and the cold-starting device by burning fuel oil refueling motor, draw a small amount of fuel oil by pump from fuel tank and enter the cold-starting device and burn, obtain energy by the fuel oil that burns in the cold-starting device circulating water of engine interior is heated.But because the uncontrollable meeting of flow of the pump of oil suction causes the waste of fuel oil; The cold start-up front engine is in halted state, the circulating water air pump inoperative of engine interior, therefore cold-starting device is to heat by the thermoconvection of circulating water self to in-engine circulating water heating, therefore has the problems such as heating effect is slow, heating is inhomogeneous, utilization efficiency of heat energy is not high.
At present, the domestic heating to motor and operator cabin or control room at industry or civilian machinery is generally adopted electric heating or is heated by circulating water of engine.And to engine cold-start, normal operation be the air-inlet grille electric heating, but for special cold area engine interior owing to oil product more thickness and the reason such as freezing, engine start is very difficult; And adopt electric heating heating or warm-air drier heating for the most domestic manufacturers of operator cabin or control room choice for use, but electric heating heating effect is very slow, and the thermal source of warm-air drier heating generally is circulating water of engine, just can't warm oneself when motor can't start.
Summary of the invention
Goal of the invention: the purpose of this utility model provide a kind of can be used for the cold area engine cold-start time in the situation that motor is carried out the engine low-temperature cold starting system of preheating without ato unit.
Technological scheme: a kind of engine low-temperature cold starting system comprises heater, oil scavenge pump, fuel pipe, intakeport, smoke-ejecting pipe, intake pipe and outlet pipe; Described heater is connected by fuel pipe with oil scavenge pump, and described intake pipe is fixedly connected with the heater top; Be provided with circulating water pump in the pipeline of described intake pipe.Circulating water pump carries out pump circulation to cooling water (liquid), and motor is heated sooner, is heated more even, and heat utilization rate is higher.
System Working Principle is: to heating installation power supply, control oil-measuring pump fuel feeding by the controller of heater inside by storage battery, by fuel oil from the fuel tank sucking-off of oil-measuring pump with capacity rating, supply with heater.Controlled by the controller of heater inside simultaneously that oil inflame is heated and the controlled circulation pump working.Circulating water pump from hydroecium water outlet or engine water outlet with cooling water (liquid) sucking-off and pump into heating in the heater, then the cooling water (liquid) after will heating forces to be drained into hydroecium water intake or engine water inlet again, heated cooling water (liquid) heats to body in the internal body circulation.
Described oil scavenge pump is oil-measuring pump.The oil inflame of the oil absorption of oil-measuring pump and the firing chamber of heater is flux matched, accomplishes that accurate fuel feeding do not waste, and Economy is higher.
In order to reduce discharge noise, the pipeline of described smoke-ejecting pipe is provided with baffler.
In order to solve in the not startup situation of motor heating thermal in the operator cabin, described heater connects intake pipe and outlet pipe place warm-air drier in parallel.
In order to control flowing of hot water in the warm-air drier, described heater connects respectively intake pipe and warm-air drier by tee union, the mouth of pipe that described tee union connects warm-air drier be provided with can switch water valve.
Beneficial effect: the utility model is simple in structure, installs easily, improves in a short period of time the temperature of system simultaneously, so that system reaches the condition that is fit to operation fast.Safer than common boiler heating, faster than electrical heating efficiency.Use more extensively, be applicable to various types of vehicles, engineering machinery, farm machinery, the engine compartment of canoe, yacht and steamer and the places such as operator cabin or control room.The oil inflame of the oil absorption of oil-measuring pump wherein and the firing chamber of heater is flux matched, accomplishes that accurate fuel feeding do not waste, and Economy is higher; Circulating water pump carries out pump circulation to cooling water (liquid) simultaneously, and motor is heated sooner, is heated more even, and heat utilization rate is higher.
