Abstract
The utility model discloses a constant pressure type diesel engine booster. The utility model is characterized in that an inlet of an air compressor (1) is communicated with an air filter (2) by an air delivery pipe (3); an outlet of the air compressor (1) is communicated with a constant pressure chamber (4) by an air delivery pipe (5); an outlet (8) of the constant pressure chamber (4) is communicated with an air intake valve of a diesel engine; the constant pressure chamber (4) is provided with an air intake compensation valve (7) and a pressure maintaining valve (6); the air compressor (1) is in transmission connection with a main shaft of the diesel engine. The utility model is the constant pressure type diesel engine booster which can enhance the air intake density of the diesel engine so as to enhance the power and the plateau restoring power of the diesel engine, and has the advantages of simple structure and easy manufacture.
Description
Technical field
The utility model relates to a kind of constant pressure type diesel pressure booster.
Background technique
Diesel engine is the mixed gas that diesel oil and air form in cylinder, reach the temperature of spontaneous combustion by Piston Compression after, ablaze voluntarily internal-combustion engine.The power of diesel engine depends on the air content in the cylinder under the situation of ceteris paribus, when air content was big, the power of diesel engine was just bigger.Some plateau sections in China, because rarefaction of air, the power of diesel engine just can not normally be brought into play; The power of the diesel engine that use in other areas also has the space of raising.
The model utility content
Technical problem to be solved in the utility model provides a kind of density of the induced air that can improve diesel engine, thereby improves the power of diesel engine and the constant pressure type diesel pressure booster of power recovery in the plateau.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the import of air compressor is communicated with air-strainer by pneumatic tube, the outlet of air compressor is communicated with the constant voltage chamber by pneumatic tube, the outlet of described constant voltage chamber is communicated with the intake valve of diesel engine, is provided with air inlet recuperation valve and pressure maintaining valve on the constant voltage chamber; Described air compressor is connected with the diesel engine spindle.
Adopt the constant pressure type diesel pressure booster of technique scheme, diesel engine directly drives air compressor work, air is after the air compressor compression, its density and temperature have all improved, make the temperature of the mixed gas of burning chamber of diesel engine be easy to temperature near spontaneous combustion, and the air participation amount of mixing with fuel oil also increases, can fully burn, given play to maximum blast potential energy, make diesel engine that good speed frequency response rate be arranged, increase the purpose of power to reach energy-conservation with moment, and reduce noxious gas emission.
In sum, the utility model is a kind of density of the induced air that can improve diesel engine, thereby improves power and the power recovery in the plateau and simple in structure, the easily manufactured constant pressure type diesel pressure booster of diesel engine.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Referring to accompanying drawing, the import of air compressor 1 is communicated with air-strainer 2 by pneumatic tube 3, the outlet of air compressor 1 is communicated with constant voltage chamber 4 by pneumatic tube 5, and described constant voltage chamber 4 outlet 8 is communicated with the intake valve of diesel engine, is provided with air inlet recuperation valve 7 and pressure maintaining valve 6 on constant voltage chamber 4; Described air compressor 1 is connected with the diesel engine spindle.
Diesel engine directly drives air compressor 1 work, air is behind air-strainer 2, be pressed into and be stored in the constant voltage chamber 4 by air compressor 1, by exporting 8 intake valves of delivering to diesel engine, and the air discharge capacity of air compressor 1 is slightly larger than the discharge capacity of diesel engine at one time, to guarantee the diesel engine proper functioning.Because air compressor 1 is inconsistent with the discharge capacity of diesel engine, a pressure maintaining valve 6 is installed constant voltage chamber 4 in, explode with preventing that constant voltage chamber 4 pressure are excessive to guarantee the diesel engine intake constant voltage.When diesel engine was made intake stroke, its intake valve was opened, because constant voltage chamber 4 outlet 8 directly is communicated with the diesel engine intake door, the high-pressure air in the constant voltage chamber 4 is in piston moves the suction cylinder.When IC Intake Valve Closes, compressor works on, and 4 inner air pressures are excessive when the constant voltage chamber, and pressure maintaining valve 6 is opened exhaust automatically, closes automatically again after pressure is reduced to certain pressure.
When diesel engine just began to start, the lack of air in the constant voltage chamber 4 because diesel engine piston moves, then produced negative pressure in the constant voltage chamber 4, and air inlet recuperation valve 7 is opened air to diesel engine is provided, and guarantees its proper functioning; Negative pressure stops after diesel engine stops suction, and air inlet recuperation valve 7 cuts out again automatically.
Because the effect of constant pressure type diesel pressure booster, the diesel engine inhaled air, pressure increases, increase in temperature, along with moving of piston, compressed, make the temperature of the mixed gas of firing chamber in the piston be easy to temperature, and the air participation amount of mixing with fuel oil also increase, so even diesel engine inhaled air when low speed near spontaneous combustion, its temperature and pressure all remains unchanged, the oil mass that diesel engine provides can fully be burnt, and can give play to maximum blast potential energy, makes diesel engine that good speed frequency response rate be arranged, increase the purpose of power to reach energy-conservation with moment, and reduce noxious gas emission.
