Abstract
The cylinder liner of two stroke IC engine (4) need not liquid coolant (normally water) cooling.And only cool off by the scavenging air in the scavenging air chamber (13) on the whole height of cylinder liner (4).This novel dry liner (4) has been eliminated because the distortion of the system that the relatively large temperature difference causes between cooling water and scavenging air is made of cylinder liner and scavenging air storage.Can cause dislocation between motor body and the working cylinder with distortion up till now.
Description
The cylinder liner of the relevant two stroke IC engine of the present invention, this cylinder liner can be held one or more cylinder liners.This cylinder liner links to each other with the scavenging air storage around the scavenging air chamber.
Traditional two stroke IC engine, particularly the cylinder liner of the marine diesel engine of low speed or cylinder block include a plurality of cylinders, these cylinder liner or cylinder block include a plurality of cylinders, these cylinder liner or cylinder block form the part of the cooling system of cooling air cylinder liner and cylinder liner, the water that is relatively hot flows therein, and water temperature is 70-80 ℃; In so-called " hot water " cooling, temperature even can reach 100-120 ℃." yet storage " is 40-50 ℃ in the temperature of the scavenging air of cylinder liner bottom.This temperature difference may cause the distortion of cylinder liner, thereby produces dislocation between motor body and working cylinder or each working cylinder.
The warpage and the distortion of the scavenging air reservoir system that the objective of the invention is to eliminate cylinder liner and link to each other with cylinder liner.Thus, according to the present invention, the scavenging air chamber on the whole height of cylinder liner with cylinder liner or each cylinder liner concentric ring around, and cylinder liner itself does not need the liquid coolant cooling.
Because this new cylinder cover need not supplied with cooling water, therefore, in cylinder liner, just can not produce the said temperature difference in front, the distortion that just can not produce cylinder liner and reservoir system yet.
Another advantage of the present invention be save on the cylinder liner complicated cooling channel and on seal arrangement.And the volume of scavenging air chamber increases in the cylinder liner, has correspondingly saved the volume of reservoir system.
Below with reference to embodiment and accompanying drawing, narrate the present invention in more detail.
Unique view in the Figure of description is the cross-sectional view of a marine diesel engine perpendicular to its bent axle and novel cylinder liner and cylinder liner, and the scavenging air apotheca links to each other with cylinder liner.
Cylinder liner 4 is contained on motor pedestal or the support post 1, and crosshead 2 and connecting rod 3 wherein are housed.Cylinder liner 6 is contained on the cylinder liner 4 together with water pipe or the support ring 5 in the middle of placing; Piston 7 is reciprocating and by piston rod 8 its to-and-fro motion is passed to crosshead 2 and connecting rod 3 in lining 6.
In a conventional manner cylinder liner is fixed on the pedestal 1 with fastening piece or bolt or like 9.
Cylinder liner 6 stretches out the part of cylinder liner and is cooled off by traditional cooling water system, anticipates as shown in its cooling channel.
In the capsul 11 of cylinder liner 4 bottoms seal arrangement 12 is arranged, the packed-piston bar passes the passage of pedestal lid and the bottom of cylinder liner 4.
Cylinder liner is inner whole to be scavenging air chamber 13, and its left side is by lid 14 sealings, and its right side links to each other with the scavenging air storage.
With traditional inverted configuration, scavenging air chamber 13 is upwards widened as tower, makes scavenging air in the cylinder liner 4 along the zone flows of the lining on the scavenging port 6, thus cooling air cylinder sleeve 4 and lining 6.Be provided with one-way valve in the air flue between storage 15 and scavenging air chamber 13, and work in known manner, improve scavenging air pressure by hydraulic booster.Increase device and supply with scavenging air from storage abreast to air chamber 13, and only under the situation of engine low load, when the exhaust eddy current increases the scavenging air underpressure that device supplies with, use work by one-way valve 17.
When cylinder liner 4 is reinforced for the cylinder body form that includes a plurality of cylinders, scavenging air storage and scavenging air chamber are separated into the each several part that links to each other with cylinder independently with the next door, and be respectively equipped with hole 18,19 on the next door, the pressure of scavenging air is equated.
Claims (1)
- A kind of cylinder liner of two stroke IC engine, this cylinder liner can be held one or more cylinder liners, this cylinder liner is around the scavenging air chamber, link to each other with the scavenging air storage, it is characterized in that scavenging air chamber (13) on the whole height of cylinder liner (4) with cylinder liner or each cylinder liner (6) concentric ring around, and cylinder liner itself does not need the liquid coolant cooling.
