Abstract
The utility model relates to a low-temperature starter for IC engines, which is provided with a heater, and water in the heater is heated by a blow lamp or other methods. The heater is connected with a small circulating loop of the cooling water of an IC engine in parallel, and the pipeline of the heater is controlled to be opened and closed by a three-way switch. The installing position of the heater causes the water outlet of the heater to be lower than the water inlet of the cooling water jacket of the IC engine. Compared with the existing starter, the low-temperature starter for IC engines is effective, reliable and safe.
Description
The utility model relates to the internal-combustion engine low-temperature startup device.
In temperature was lower than 0 ℃ environment, internal combustion engine start had just become difficulty, and especially in temperature low winter that reaches the severe cold areas of subzero tens degree Celsius, this difficulty is just even more serious.Producing this difficult main cause is: temperature is too low, causes in the firing chamber compression end of a period air or mixture temperature on the low side; Temperature is low to make the fuel pulverised bad; Temperature is low, and viscosity is big with regard to Yin Wendu is low for machine oil, makes internal-combustion engine on the low side because of the resistance of start starts rotating speed greatly.Be born from internal-combustion engine, people did not just stop the research to internal-combustion engine cold-starting problem, successively produced the device of various help cold-startings, they can be divided into two classes haply: a class is mounted in heat is given in electricity consumption in the suction tude to the air inlet air inlet device, another kind of is the device that the internal-combustion engine engine body exterior is heated, and for example waters body, toasts body with blowtorch or fuel burning with hot water.This two classes device all can be accelerated the startup of internal-combustion engine under low temperature environment more effectively, and still, also there is the shortcoming of oneself separately in they.A class to air inlet give heat device because of heating power little and the heating very local, so it is undesirable to the machine effect that the too low environment of temperature or discharge capacity are bigger, one class device heating position, back is an engine body exterior, rather than directly influence around the firing chamber of machine intimate of internal combustion engine start speed, so efficient is very low, need just can make internal combustion engine start long heating time, and, trouble, bothersome and dangerous.
The purpose of this utility model is, a kind of internal-combustion engine low-temperature startup device is provided, and it can overcome above-mentioned existing starting drive deficiency separately, can guarantee that easily and reliably internal-combustion engine starts rapidly in the very low environment of temperature.
The internal-combustion engine low-temperature startup device that the utility model provides, there is one to heat the wherein heater of water (4) by blowtorch or other burner (5), be communicated with pipe and three-way cock between the water outlet of its water intake and the thermostat (2) of internal-combustion engine (1) cooling system, be communicated with pipe between its water outlet and internal-combustion engine (1) the cooling jacket water inlet, even the water loop of heater via (4) becomes one and the road that is linked back in the short circle loop of internal-combustion engine cooling system water, and the mounting point of said heater (4) makes its water outlet be lower than the water inlet of the cooling jacket on the internal-combustion engine (1).
Can in the pipeline of above-mentioned starting drive, add a little water pump (6) that drives by storage battery,, internal-combustion engine be started quickly to quicken circulating of hot water.Can also on the intake pipe of heater (4), adorn a water-thermometer (7), judge and to have begun starting apparatus combustion engine to observe water temperature.
The above-mentioned internal-combustion engine low-temperature startup device that the utility model provides, because the water that is heated by heater directly enters the cooling jacket in the internal-combustion engine, hot water directly heats cylinder liner and the cylinder head bottom surface that constitutes combustion chambers of internal combustion engines, so can effectively and quickly improve the temperature of firing chamber, promote fuel atomizing and catch fire.Compare with the existing thermic devices of giving that heat is given in air inlet that is loaded in the suction tude, its heating power is obviously much bigger.And the hot water that enters the cooling water of internal combustion engine cover warms up internal-combustion engine from the inside to surface gradually, can reduce the resistance of start that machine viscosity is caused more effectively.
Be an indefiniteness embodiment of the present utility model shown in the accompanying drawing 1, in the representative of each numerical chracter be:
The 1-internal combustion engine main body, the thermostat of 2-internal-combustion engine cooling system
The radiator 4-heater of 3-internal-combustion engine cooling system
The little water pump of 5-blowtorch 6-
The 7-water-thermometer
Among the figure, the major cycle loop that cooling water was walked when heavy line represented that the cooling water of internal combustion engine temperature is higher, the short circle loop that cooling water was walked when dotted line represented that the cooling water of internal combustion engine temperature is low, fine line is represented the heater connecting pipeline in this starting drive, arrow is represented the flow direction of water.
Heater (4) can adopt the structure that is similar to shower heater, should extend wherein to be subjected to the length of hot coil as far as possible.
During startup, thermostat (2) three-way cock is afterwards pulled the position of connecting heater (4) loop, with blowtorch (5) barbecue heater (4), water pump (6) and storage battery are connected, heated water circulates with regard to depending on water pump.Certainly, because the mounting point of heater (4) makes its water outlet be lower than cooling jacket water inlet on the internal combustion engine main body (1), can not depend on natural convection to form the circulation of hot water so do not start water pump (6) yet.
Claims (3)
1. internal-combustion engine low-temperature startup device.It is characterized in that: have one to heat the wherein heater of water (4) by blowtorch or other burner (5), be communicated with pipe and three-way cock between the water outlet of its water intake and the thermostat (2) of internal-combustion engine (1) cooling system, be communicated with pipe between its water outlet and internal-combustion engine (1) the cooling jacket water inlet, even the water loop of heater via (4) becomes one and the road that is linked back in the short circle loop of internal-combustion engine cooling system water, and the mounting point of said heater (4) makes its water outlet be lower than the water inlet of the cooling jacket on the internal-combustion engine (1).
2. internal-combustion engine low-temperature startup device as claimed in claim 1 is characterized in that, a little water pump (6) that is driven by storage battery is housed in said loop.
