Abstract
An exhaust structure used for a cooling system of a pressurized gasoline engine comprises a pressurizer, an engine, a liquid storage pot, and a water-air separator. The water-air separator is connected with the liquid storage pot through an exhaust pipe extending from the top. The water-air separator is connected with a water return pipe of the pressurizer through a water inlet pipe extending from the middle portion. The water-air separator is connected with a water inlet pipe of the engine through a water outlet pipe at the bottom. Cooling water which passes the pressurizer is introduced to the water-air separator and water and air are separated in the water-air separator. Air goes out through the connection of a connecting pipe and the liquid storage pot. Liquid run back to the water inlet pipe of the engine and continue to cycle. Air in the backwater of the pressurizer is effectively separated and cooling efficiency of the engine is improved.
Description
Technical field
The utility model belongs to engine technology, particularly a kind of exhaust structure for the supercharging gasoline engine cooling system.
Background technique
Along with the development of engine technology, present diesel engine has substantially all adopted supercharging, and the petrol engine supercharging technology also develops rapidly.For power and the moment of torsion that improves small displacement engine, improve fuel economy and reduce exhaust emissions, make motor miniaturization, lightweight, supercharging technology, particularly turbosupercharging, it is more and more general to become.Exhaust gas turbocharge (hereinafter to be referred as supercharging) is to drive waste gas pump to drive pneumatic pump compression fresh air take the waste gas of engine emission as power source, thereby improves air inflow.This pressurized machine technology is the most ripe, uses the most general.
Because extreme temperatures in the turbosupercharger is so pressurized machine needs the water route to cool off.Adopt at present and more generally utilize short circle water that pressurized machine is cooled off, namely cooling water is drawn from temperature-regualting base, gets back to the water inflow of the engine pipe behind the cooling of charge device.This cooling cycle structure is simple, with low cost, but but drawn another problem: the cooling water of process pressurized machine is owing to high temperature seethes with excitement, produce a lot of bubbles, these bubbles enter motor can make the cooling effectiveness of whole cooling system greatly reduce, even can cause the mistake cause thermal damage of gray iron, pressurized machine etc. zero.
Summary of the invention
For the prior art above shortcomings, the utility model proposes a kind of exhaust structure for the supercharging gasoline engine cooling system, adopt moisture separator and connection associated ping thereof, effectively separate the gas in the pressurized machine backwater and discharge raising engine cooling efficient.
The technical solution of the utility model is as follows:
A kind of exhaust structure for the supercharging gasoline engine cooling system comprises pressurized machine, motor, liquid storage kettle and a moisture separator.Described moisture separator picks out outlet pipe by the top and connects the liquid storage kettle, and the intake pipe that moisture separator picks out by the middle part connects the return pipe of pressurized machine, and moisture separator is by the intake pipe of the outlet pipe connecting engine of bottom.Like this by introducing moisture separator through the cooling water behind the pressurized machine, in separator, water is separated with gas, gas is connected into the liquid storage kettle by connecting tube and drains, liquid flows back to the water inflow of the engine pipe and continues circulation, can effectively separate the gas in the pressurized machine backwater and discharge raising engine cooling efficient.
Further, there is dividing plate the inside of described moisture separator, vertically arranges, and is relative with the mouth of pipe of intake pipe, can reduce liquid velocity like this, is convenient to liquids and gases are separated.
Its advantage of the utility model is:
1, by moisture separator the gas in the pressurized machine backwater is separated and drain, improve the efficient of cooling system, guarantee whole motor reliability of operation.
2, simple in structure, reliability is high, and is with low cost.
3, moisture separator is independent setting, is to be connected by pipeline with other parts, is convenient to check, change.

Fig. 3: oil and water seperator top structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is conducted further description.
Figure 1 shows that the structural representation of whole system, formed by outlet pipe 1, moisture separator 2, intake pipe 3, outlet pipe 4, motor 5, pressurized machine 6 and liquid storage kettle 7.Outlet pipe 1 is connected to the top of moisture separator 2, and intake pipe 3 is connected to the middle part, and outlet pipe 4 is connected to the bottom.The major function of moisture separator 2 is with gentle the separating of water in the water inlet.Moisture separator 2 connects liquid storage kettle 7 by outlet pipe 1, but interface should be positioned at more than the highest water level, and the gas of being convenient to separate is discharged by the liquid storage kettle.Moisture separator 2 is by the return pipe of intake pipe 3 connection pressurized machines 6, and the high-temperature water that pressurized machine is included gas is introduced in the separator.Moisture separator 2 is introduced complete machine continuation circulation by the intake pipe of outlet pipe 4 connecting engines 5 with the water that moisture separator 2 is separated.Moisture separator 2 is installed on the cylinder head by construction bolt.
The structure of moisture separator 2 as shown in Figures 2 and 3, it is a moisture separator that volume is box, mainly comprises relief opening 21, installs and fixes hole 22, water intake 24, dividing plate 25 and water outlet 23.Relief opening 21 diameters are all less than water intake 24 and water outlet 23, are in order not allow liquid discharge, to cause heat of engine to scatter and disappear as far as possible.Dividing plate 25 is in moisture separator 2 interior vertical settings, and is relative with the mouth of pipe of intake pipe 3.Effect is to prevent liquid flow at high speed in separator, easier the separating of the static rear gas of liquid.
