Abstract
The invention relates to a turbo-charging automatic protection device, which comprises a hydraulic manifold block, wherein the hydraulic manifold block is provided with an oil inlet port and a starting electromagnetic valve, the oil inlet port is connected with a starting accumulator and a parking accumulator through a check valve, the starting electromagnetic valve is connected with the starting accumulator, and the outlet of the starting electromagnetic valve is connected with an oil outlet through an oil outlet. The instant and reliable lubrication problem of the turbo-charger is solved when the car is cold started and is stopped suddenly, so the service life of the turbo-charger is effectively prolonged, the power performance of the car is improved, the fuel oil consumption is reduced, and the tail gas exhaustion is more environment-friendly.
Description
Technical field
The present invention relates to a kind of turbo-charging automatic protection device, is the self oiling protective system of automobile and other supercharging of internal combustion engine turbine of exhaust gas turbocharge, is specially adapted to the protection of the pressurized machine of float petrol car.
Background technique
The diesel engine for automobile and the minority petrol engine of big discharge capacity adopt exhaust gas turbocharge mostly at present, and motor is under the identical condition of volume weight, and power can improve 30%-100% even more, and energy-conservation environmental protection again.
Because exhaust gas turbine proper functioning rotating speed very high (several ten thousand to tens0000 rev/mins), adopt two floating sliding bearings almost entirely, therefore to the very high requirement that is supplied with of lubricant oil, lubricant oil has gently premature wear then of shortage slightly, and is heavy then dry grind and scrap.Just most of in the market vehicles that turbosupercharger is housed; manufacturer does not adopt the technology protection measure (cold start-up and anxious stopping phase) what reduces wear; just formulate strict working specification and retrain the user; prolong the working life (artificial control) of pressurized machine in order to protection; the user is difficult to by manipulating the strict execution of specification; there is misoperation just to cause many artificial damages slightly, brings not small economy loss, manufacturer to make troubles to the user, thus particularly thorny.
Summary of the invention
Its purpose of the present invention just is to provide a kind of turbo-charging automatic protection device; realized that automobile is in time lubricated reliably to turbosupercharger when cold start-up and crash-stop; prolonged the working life of pressurized machine effectively; improved the power performance of automobile simultaneously; reduced fuel consume, exhaust emissions is environmental protection more.
The technological scheme that the present invention takes for achieving the above object; a kind of turbo-charging automatic protection device; comprise hydraulic manifold block; described hydraulic manifold block is provided with the oil-feed interface, starts solenoid valve; described oil-feed interface connects startup accumulator, parking accumulator through one-way valve; described startup solenoid valve import connects the startup accumulator, and described startup electromagnetic valve outlet connects oil outlet through filter cleaner.
Compared with prior art the present invention has the following advantages.
Owing to adopted the structural design that starts accumulator, parking accumulator, thereby realized that automobile is in time lubricated reliably to turbosupercharger when cold start-up and crash-stop, prolonged the working life of pressurized machine effectively, improved the power performance of automobile simultaneously, reduced fuel consume, exhaust emissions is environmental protection more.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Accompanying drawing is this apparatus structure principle schematic.
Embodiment
Comprise hydraulic manifold block, as shown in drawings, described hydraulic manifold block is provided with oil-feed interface 1, starts solenoid valve 6, described oil-feed interface 1 connects startup accumulator 10, parking accumulator 7 through one- way valve 5,11, described startup solenoid valve 6 imports connect startup accumulator 10, and described startup solenoid valve 6 outlets connect oil outlets 8 through filter cleaner 9.
Described hydraulic manifold block is provided with and starts fault sensor 12, trouble of shutdown sensor 4, oil temperature sensor 3 and electric heater 13.
Working procedure
Stored the lubricant oil of some in advance owing to startup accumulator 10 in the cold start-up stage, startup solenoid valve 6 is opened after receiving actuating signal, so lubricant oil promptly flows to pressurized machine by oil out port 8 under the effect of pneumatic spring, whether 3 decisions of simultaneous temperature sensor heat, so lubricant oil lags behind and the low excessively problem of winter oil temperature start up period of the elimination.The lubricant oil that is come by main oil gallery behind the engine start at first pressurizes to two accumulators by two one-way valves, and the accumulator that stops then carries out the pressurize fuel feeding through one-way valve 2 to pressurized machine and comes for its proper functioning.Anxious stopping phase: because motor quits work, main oil gallery pressure rapidly disappears, so one-way valve is closed rapidly under overbottom pressure, so continuing fuel feeding, the parking accumulator stopped until supercharger rotor safety in two to three minutes, so this technology can make the wearing and tearing of turbine rotor bearing reduce to minimum.
This device comprises startup accumulator 10, parking accumulator 7, hydraulic manifold block, filter cleaner 9, starts fault sensor 12, starts solenoid valve 6, trouble of shutdown sensor 4, oil temperature sensor 3, electric heater 13, oil-feed interface 1, oil out port 8.
Accumulator is an air chamber for handstand has the seal container top of certain altitude, and the bottom is that this example of shoe cream room (its profile can be: circular, square, polygonal or other given shape) is for square.
Startup, trouble of shutdown sensor are warned device by electrical signal or capillary tube with instrument or fault acousto-optic that fault message is uploaded on the instrument panel, so that the driver in time finds fault, keep in repair immediately, maintain, remove a hidden danger.
Start solenoid valve, come the switching of control oil channel with the startup electrical signal, with the retardation phenomenon of elimination oil pump fuel feeding, the wearing and tearing the start up period of having reduced.
Oil temperature sensor and electric heater are because lubricant oil is along with its viscosity increase of reduction of atmospheric temperature, mobile variation, greasy property weaken, so oily temperature sensing cooperates with heater to be eliminated because of the low excessively unfavorable factor of winter oil temperature.
Filter cleaner, owing in the machine oil trickle mechanical admixture is arranged, it can quicken the wearing and tearing of pressurized machine bearing, sets up filter cleaner can guarantee that turbine rotor has enough working life.
Hydraulic manifold block, material are aluminum alloy, brass, stainless steel or other material, are processed with longitudinal and transverse pipelines with staggered thereon, also have many big or small one connection screw to make each parts Colaesce become an integral body.
