Abstract
The utility model relates to an adiabatic engine with a ceramic chamber lining. The utility model comprises a cylinder body, a piston, an air inlet and outlet pipe, adiabatic engineering ceramic chamber linings (blocks), etc., wherein, the adiabatic engineering ceramic chamber linings (blocks) are stuck and lined on surfaces of thermocontact positions, such as the inner surface of a cylinder, the top of the piston, a combustion chamber of the cylinder, etc., by inorganic binders. When the utility model is utilized, the adiabatic work of the combustion chamber of the engine can be realized, the surface temperature of the combustion chamber can be reduced, heat transfer loss can be decreased, oil consumption is reduced, inflating effect can be enhanced, the original forced circulation cooling system which takes water and oil as mediums can be cancelled, production cost is reduced, and the economical efficiency of the engine is enhanced.
Description
The utility model relates to motor, especially a kind of sticking ceramic chamber lining adiabatic engine made from engineering ceramics that is lining in the cylinder internal surface of lining.
A large amount of heats that existing motor produces in the cylinder when draining work, ad hoc have a recirculated cooling water case, to reduce the temperature rise of motor, makes it to keep proper functioning.Carry out reactive sintering again after also having the people that stupalith is sprayed on metal wadding surface.Make the motor insulated combustion chamber, or all adopt stupalith to make adiabatic engine.But the former is because the thermal expansion coefficient of metal and pottery differs too big, and ceramic plane produces be full of cracks and can not reach the effect of anticipation during engine operation; The latter is because complex process, and cost is too high and be difficult to popularize and implement.
It is a kind of simple in structure that the purpose of this utility model is to provide, and makes easily, with low cost, the ceramic chamber lining adiabatic engine of insulation effect excellence.
When comprising cylinder block, piston, air inlet-outlet pipe, ceramic chamber lining adiabatic engine of the present utility model glues the formations such as insulating ceramic material that are lining in surfaces, position such as cylinder surfaces, piston head, head combustion chamber with inorganic binder.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, ceramic chamber lining adiabatic engine of the present utility model comprises engine body and the sticking ceramic thermal insulation lining (8) that is lining in cylinder (9) internal surface, the sticking ceramic thermal insulation pad (6) that is lining in piston (10) top surface, stickingly is lining in the ceramic thermal insulation pad (5) of suction valve and outlet valve end face, sticking ceramic thermal insulation lining (1) and (2) that are lining in suction tude and outlet pipe inwall, and glues the ceramic thermal insulation pad (4) that is lining in cylinder head (3) combustor surface etc.For the ease of making and installation and maintenance, embedding is across metal spacer (7) between ceramic thermal insulation lining (8) and the cylinder (9), and the sticking lining of ceramic thermal insulation lining (8) is at spacer (7) internal surface.Ceramic thermal insulation lining (piece) sticks to by on the sleeve member surface with inorganic binder.
During engine operation, piston (10) is done up and down to move back and forth work done at a high speed, produces a large amount of heats, and outwards distributes by surface of contact such as cylinder wall, piston end surface and exhaust ducts.These heat losss cause that engine power and thermal efficiency decline account for about 15% of the theoretical mixed cycle power and the thermal efficiency.Ceramic chamber lining adiabatic engine of the present utility model, cylinder inner wall and all adhered to the heat contact surface have fabulous thermal shock resistance, excellent abrasive, the engineering ceramics heat insulation housing (piece) of resistance to flexure and good chemical stability preferably.Thereby, can realize the adiabatic operation of engine chamber, reduce the heat transfer loss of motor significantly, improve the Economy of motor, reduce oil consumption.Because the firing chamber of making motor with stupalith can make the material surface temperature the firing chamber in be minimized, originally fresh air enters heating behind the cylinder, temperature rise, heavily the rate decline situation that influences charging efficiency is improved, and has improved the inflation effect.In addition, because used ceramic thermal insulation lining (piece), motor can cancel original Yi Shui, oil be the positive drive type circulating cooling system of medium, reduces the cost of production of motor, reduces mechanical friction loss.Also the temperature owing to the engine air inside wall of cylinder, piston is minimized.Be splashed to lubricant oil that this part component carries out work and be improved, thereby improved the lubrication effect of motor and reduced the consumption of lubricant oil by the oxidation deterioration of heating, the situation of decomposing coking.
Claims (2)
1, a kind of ceramic chamber lining adiabatic engine is made of cylinder block, piston, air inlet-outlet pipe etc.The combustor surface and air inlet-outlet pipe surface and all sticking engineering ceramics heat insulation housing (piece) (8), (6), (4), (5), (2) and (1) of serving as a contrast of air inlet and exhaust valve end face that it is characterized in that (9) surface, piston (10) top surface, cylinder head (3) in cylinder.
2, ceramics adiabatic engine as claimed in claim 1 is characterized in that embedding is across metal spacer (7) between cylinder block (9) and the adiabatic pad (8).
