Abstract
The utility model relates to an inlet channel of a diesel engine, which belongs to the technical field of diesel engines, and comprises a flat channel part and a helical channel part, wherein the flat channel part and the helical channel part are an integrated channel, the shape of the flat channel part is similar to a linear channel, the helical channel part is a helical forniciform channel, the circumference diameter which is surrounded by the helical channel part is 19.5mm-22mm, and the radius of a circular arc of an excessive part of the flat channel part and the helical channel part is 23mm-27mm. After using the inlet channel of the diesel engine, a lower swirl ratio can be achieved, the flow resistance of gas is reduced, the charging efficiency of the diesel engine is increased, fuel oil and the air are fully mixed, the fuel oil of the diesel engine is fully burnt, and the power of the diesel engine is increased.
Description
Technical field
The utility model relates to technical field of internal combustion engines, is a kind of 493 diesel engine direct injection intake ducts more specifically.
Background technique
The diesel engine intake road structural design of prior art is not satisfactory, the shape that intake duct adopts makes the intake duct swirl rate big, the strength of vortex that produces will make the inlet stream dynamic resistance strengthen greatly, also can cause fuel oil is foundered on the cylinder wall, reduces the diesel engine fuel oil combustion efficiency.
Summary of the invention
The utility model provides a kind of and can reduce gas flow resistance, raising diesel engine power at the deficiencies in the prior art, reduces the diesel engine intake road of the toxic emission of diesel engine simultaneously.
A kind of diesel engine intake road comprises smooth pipe section, helical pipe part, and described smooth pipe section and helical pipe partly are the pipeline of one; Described smooth pipe section is the near linear pipeline, its sectional shape is a rectangular, the size a in cross section is 42mm, b is 31mm, the central axis distance L of the air inlet end face of smooth pipe section and helical pipe part is 86mm, and the central axis of smooth pipe section and horizontal angle theta are 11 °; Described helical pipe partly is a helical buckling shape pipeline, and the end face of giving vent to anger is a diameter phi
1Circle for 35.5mm; Partly the give vent to anger height H of end face of the air inlet end face center line of described smooth pipe section and helical pipe is 53mm; The circle diameter φ that the helical pipe part is surrounded
2Be 19.5mm～22mm; The radius r of the excessive partial arc of smooth pipe section and helical pipe part is 23mm～27mm.
The preferred compositions of this model utility is: the circle diameter φ that described helical pipe part is surrounded
2Be 20mm～21mm; The radius r of the excessive partial arc of described smooth pipe section and helical pipe part is 24mm～26mm.
The optimum combination of this model utility is: the circle diameter φ that described helical pipe part is surrounded
2Be 20.6mm; The radius r of the excessive partial arc of described smooth pipe section and helical pipe part is 25mm.
The beneficial effect of this model utility is: after adopting the size combinations of this intake duct, can reach lower swirl rate, thereby reduced the gas flow resistance, improved the diesel engine charging efficiency, in contracting stroke, the motor entrance pressure avoided strong air whirl that fuel oil is foundered on the cylinder wall, fuel oil is fully mixed with air, and the diesel engine fuel oil sufficient combustion has improved diesel engine power.
