Abstract
The utility model discloses a heat-insulation shield of a pressure booster of a diesel engine, comprising a heat-insulation shield body. The heat-insulation shield body is a crown surface which is adapted with the surface of the pressure booster; the front end of the heat-insulation shield body is provided with a fixing part fixedly connected with an air intake manifold; and one side of the heat-insulation shield body is provided with a bracket fixedly connected with an exhaust bent pipe. In the utility model, the limited space at the exhaust side of the engine is reasonably utilized, and the surfaces of an exhaust manifold and the pressure booster are selected as guide surfaces, thereby the structure is compact and simple; the heat-insulation shield shares a fixed bolt with the intake manifold, thereby having simple structure and convenient installation; the upper half part of the heat-insulation shield is also used as a heat-insulation structure of the exhaust manifold so that the heat-insulation shield enhances the heat-insulation effect, has large covering area and favorable heat-insulation effect, and can effectively protect and insulate heat for the pressure booster with high temperature.
Description
Technical field
The utility model relates to a kind of heat insulation protective equipment, particularly a kind of diesel pressure booster thermal shield.
Background technique
At present, the general exhaust-gas turbocharger that adopts on motor, turbosupercharger is a kind ofly to utilize the dump energy in the engine exhaust to come the air pump of work.The motion of non-supercharged engine by bent axle be suck air from atmosphere directly, and pressurized machine provides pressurized air to motor.Increase owing to enter the air of cylinder,, make the bigger power of motor output and have higher combustion efficiency so allow to spray into more fuel oil.This means that a size motor identical with weight can produce bigger power after supercharging, in other words, a small displacement engine can produce after supercharging and the power identical than large-duty engine.Other saves advantages such as fuel oil and reduction discharging in addition.
But, in supercharged engine work, the combustion gas of High Temperature High Pressure promotes turbine rotation, can be heated to very high temperature to turbine case, this just exists certain danger, scalds the operator easily, and a large amount of heats can be distributed to machine room in the turbine case of high temperature surface, the temperature of machine room is raise, influence operating environment.Traditional engine supercharger thermal shield be not effect of heat insulation undesirable be exactly that structural design is too complicated, tracing it to its cause mainly is to cause because the thermal shield structural design is unreasonable and the mounting point is improper.
Summary of the invention
The utility model provides a kind of easy for installation for solving the technical problem that exists in the known technology, and area coverage is big, the diesel pressure booster thermal shield of good heat-insulation effect.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of diesel pressure booster thermal shield, comprise the thermal shield body, described thermal shield body is and the adaptive arc surface in pressurized machine surface, the front end of described thermal shield body is provided with the fixing part affixed with intake manifold, and a side of described thermal shield body is provided with the support affixed with exhaust elbow.
The utility model can also adopt following technical measures:
Above-mentioned diesel pressure booster thermal shield is characterized in: described thermal shield body is provided with pressurized machine machine oil oil inlet pipe opening and motor dipstick tube opening.
Above-mentioned diesel pressure booster thermal shield is characterized in: the surface of this thermal shield is provided with yellow zinc coating.
Advantage and the good effect that the utlity model has are: rationally utilized the confined space of the exhaust side of engine, the surface of applying gas exhaust manifold and pressurized machine is as guide surface (the higher position of temperature on the pressurized machine), compact structure, succinct; With the shared fixing bolt of intake manifold, simple in structure, easy for installation; The heat-insulating structure of upper half part double as gas exhaust manifold has strengthened effect of heat insulation, and area coverage is big, and good heat-insulation effect can be effectively protected with heat insulation the pressurized machine of high temperature.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Among the figure: 1, body, 2, the oil inlet pipe opening, 3, the dipstick tube opening, 4, fixing part, 5, support.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of diesel pressure booster thermal shield of the utility model, comprise thermal shield body 1, thermal shield body 1 is and the adaptive arc surface in pressurized machine surface, one end of thermal shield body 1 is provided with the fixing part 4 affixed with intake manifold, and a side of thermal shield body is provided with the support 5 affixed with exhaust elbow.Thermal shield body 1 is provided with pressurized machine machine oil oil inlet pipe opening 2 and motor dipstick tube opening 3, can make entire mechanism compact more under the prerequisite that does not interfere.Yellow zinc coating is adopted on the surface of this thermal shield, when taking into account aesthetic, also can play the high temperature warning effect.
The utility model body adopts globoidal structure, and a side is fixed on the intake manifold, and lateral support is fixed on the exhaust elbow.Two aperture positions get out of the way pressurized machine machine oil oil inlet pipe and motor dipstick pipe respectively on the cambered surface.Simple in structure, coverage area is big, and is easy for installation, and good heat-insulation effect can effectively protect car body not to be subjected to the pressurized machine temperatures involved.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not breaking away under the scope situation that the utility model aim and claim protect; according to above-mentioned mentality of designing; can also extend a lot of forms; according to the structural feature separately of high-temperature component on the motor; select its surface as guide surface; design more simply suitable; the heat-proof device of compact structure is to reduce the influence of high-temperature component to surrounding structure as far as possible.These all belong within the protection domain of the present utility model.
