Abstract
The invention relates to an air intake heating device of the engine, which comprises an air intake main pipe and a ventilation pipe which is externally connected with a crankcase. The invention is characterized in that a heater is arranged on the outer wall of an air intake end of the air intake main pipe. The heater is an electrical heating pipe or an annular hollow water jacket. The water jacket is provided with a water inlet pipe linker and a water outlet linker. The water inlet pipe linker and the water outlet linker are parallelly or serially connected with a cooling system cycle of the engine. The problem of easy icing choked of the crankcase ventilation system in low temperature environment is solved by adopting the heater to pre-heat the crankcase ventilation system of engine. The invention has a simple structure; therefore, the invention is in particular applicable to the crankcase ventilation system of small discharging engine.
Description
Technical field
The present invention relates to a kind of air-intake heating mechanism of engine.Relate in particular to the local heating in the engine aspirating system, be primarily aimed at and solve the difficult problem that crankcase ventilation system easily freezes and stops up in low temperature environment.
Background technique
At present, automobile with small output volumn is popularized gradually, pipeline in the small displacement engine crankcase ventilation system is narrow, and throughput is less, in the winter time Han Leng area, during galloping, air input of engine by air increases, the cool air high-speed motion in the air induction hose, the aqueous vapor that is mingled with very easily with ventilation system in the small amount of thermal airsetting build-up ice, stop up tiny ventilation duct, have a strong impact on the proper functioning of motor.
Do not find a kind of device that is used for the engine crankshaft ventilation system air inlet is carried out preheating as yet.
Summary of the invention
The technical problem to be solved in the present invention is, in order to remedy the deficiency of existing car engine machine technology, and provides a kind of simple in structure, can carry out the air-intake heating mechanism of engine of preheating to the engine crankshaft ventilation system air inlet.
The present invention solves the problems of the technologies described above to adopt following technological scheme: a kind of air-intake heating mechanism of engine, comprise that air inlet is responsible for and the ventilation duct of external crankcase, and it is characterized in that: be responsible for the inlet end outer wall in air inlet one heater is set.
Described heater is an electric heating tube.
Described heater can also be an annular hollow water jacket, and fill hose joint, titting water outlet are arranged on the water jacket.Fill hose joint on the described heater, titting water outlet parallel connection or the circulation of series connection engine-cooling system.
Good effect of the present invention is: because the main heater that adopts carries out preheating to the engine crankshaft ventilation system air inlet, solved the difficult problem that crankcase ventilation system easily freezes and stops up in low temperature environment.Simple in structure.
The present invention will be further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a plan view of the present invention.
Fig. 2 is the organigram of analysing and observe of the present invention.
Fig. 3 is a plan view of the present invention.
Fig. 4 is a stereogram of the present invention.
Among the figure: 1. be responsible for, 2. heater, 3. fill hose joint, 4. titting water outlet, 5. ventilation duct.
Embodiment
1 one kinds of air-intake heating mechanism of engine of embodiment comprise that air inlet is responsible for the ventilation duct (5) of (1) and external crankcase, it is characterized in that: be responsible for (1) inlet end outer wall in air inlet one heater (2) is set.Described heater (2) is an electric heating tube.
Working procedure of the present invention: behind automobile starting, engine cooling water begins circulation, circulating water flows through between (4) at fill hose joint (3), titting water outlet in the air-intake heating mechanism upper heater, the ventilation duct of being responsible for wall and connecing crankcase is heated, heats up, the air temperature rising before the throttle valve body.When high engine speeds turned round, the cool air amount that motor sucks increased, but the also rising simultaneously of the temperature of circulating water can effectively guarantee the heat that adds to ventilation duct and ambient gas, thereby avoid causing icing phenomenon.Because flow is not very big, when guaranteeing to add heat, can not bring tangible harmful effect to warm air system yet, guarantee the normal operation of motor in low temperature environment.
Claims (4)
1. air-intake heating mechanism of engine comprises that air inlet is responsible for the ventilation duct (5) of (1) and external crankcase, it is characterized in that: be responsible for (1) inlet end outer wall in air inlet one heater (2) is set.
2. air-intake heating mechanism of engine according to claim 1 is characterized in that: described heater (2) is an electric heating tube.
3. air-intake heating mechanism of engine according to claim 1 is characterized in that: described heater (2) is an annular hollow water jacket, and fill hose joint (3), titting water outlet (4) are arranged on the water jacket.
4. air-intake heating mechanism of engine according to claim 3 is characterized in that: the fill hose joint (3) on the described heater (2), titting water outlet (4) parallel connection or the circulation of series connection engine-cooling system.
