Description
Technical field
The present invention relates to a kind of engine starting system, particularly a kind of motor low-temperature cool starting system of cold area equipment.
Background technique
Engine cold-start is that mean engine shut down for some time apart from last time, begins under the corresponding to situation of portion's temperature and ambient temperature within it to start.Correspondingly with it start thermal starting in addition, be exactly mean engine apart from off time last time soon, portion still has under the situation of higher surplus temperature and starts within it.
Engine cold-start is more difficult than thermal starting, and is 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 possibly be in and solidify or the deposition 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 obtains well lubricated, and then loading.
Cold-starting device is the vehicle-mounted heating equipment of motor 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, thoroughly eliminate the cold start-up wearing and tearing of automobile motor car engine and the operator cabin of parking in the winter low temperature cold environment.Its working principle is to utilize 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 through the heat that burns gasoline produced, and operator cabin is heated up.
Chinese invention patent CN102359429 discloses a kind of motor low-temperature cool starting system; Comprise the cold-starting device that is used for adding oil turbine from the pump of fuel tank oil suction with through the burning fuel oil; Draw a small amount of fuel oil through pump from fuel tank and get into the cold-starting device and burn, obtain energy through 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 through the thermoconvection of circulating water self to in-engine circulating water heating, therefore has problems such as heats 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 through engine cycles water.And to engine cold-start, general what use is the air-inlet grille electric heating, but for special cold area engine interior owing to oil product thickness and reason such as freezing more, engine start is difficulty very; And select to use the warm or warm-air drier heating of the electric heating system of employing for the most domestic manufacturers of operator cabin or control room; But the warm effect of electric heating system is very slow; And the warm thermal source of warm braw mechanism generally is an engine cycles water, when motor can't start, just can't warm oneself.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of motor low-temperature cool starting system that motor is carried out preheating under without the situation of ato unit can be used for the cold area engine cold-start time.
Technological scheme: a kind of motor low-temperature cool starting system comprises heater, oil scavenge pump, fuel pipe, intakeport, smoke-ejecting pipe, intake pipe and outlet pipe; Said heater is connected through fuel pipe with oil scavenge pump, and said intake pipe is connected with the heater roof anchorage; Be provided with circulating water pump in the pipeline of said intake pipe.Circulating water pump carries out pump circulation to cooling water (liquid), and motor is heated sooner, and it is more even to be heated, and the heat energy utilization rate is higher.
The system works principle is: give heating installation power supply through storage battery, control the oil-measuring pump fuel feeding by the controller that heater is inner, through fuel oil from the fuel tank sucking-off of oil-measuring pump with capacity rating, supply with heater.Control simultaneously that oil inflame is heated and the control circle pump working by the inner controller of heater.Circulating water pump from hydroecium water outlet or motor water outlet with cooling water (liquid) sucking-off and pump into heating in the heater; Cooling water (liquid) after will heating then 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.
Said oil scavenge pump is an 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 said smoke-ejecting pipe is provided with baffler.
In order to solve under the not startup situation of motor heating thermal in the operator cabin, said heater connects intake pipe and the parallelly connected warm-air drier in outlet pipe place.
In order to control flowing of hot water in the warm-air drier, said heater connects intake pipe and warm-air drier respectively through tee union, the mouth of pipe that said tee union connects warm-air drier be provided with can switch water valve.
Beneficial effect: the present invention is simple in structure, installs easily, improves the temperature of system simultaneously in a short period of time, and the system that makes reaches the condition that is fit to operation fast.Boiler heating than common is safer, and is 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 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, and it is more even to be heated, and the heat energy utilization rate is higher.
