Abstract
The invention relates to a power dynamometer, especially relating to a power dynamometer used for an internal combustion engine. The power dynamometer comprises a rotor which is connected with an internal combustion engine shaft. The rotor is opened with a groove. The groove is provided with a belt inside to connect with a rotating wheel of an electric generator. The electric generator is connected with a first power meter. The electric generator is connected with an external resistor. A connecting line between the generator and the external resistor is provided with a second power meter. By employing the above structure, it is convenient to measure output power and drive power of the internal combustion engine.
Description
Technical field
The present invention relates to a kind of dynamometer, the dynamometer that particularly a kind of internal combustion engine is used.
Background technology
Dynamometer is the output torque of measurement mechanical or the device of driving torque.If record the rotating speed of machinery simultaneously, also can calculate the output power or the driving power of machinery.Dynamometer mainly is used for measuring the shaft power characteristic of machineries such as generator, motor, internal combustion engine, gas turbine and pump.
Internal combustion engine dynamometer commonly used now is a hydraulic dynamometer; China utility model patent instructions CN201072366Y just discloses a kind of hydraulic dynamometer; Comprise airframe components, force measuring machine, advance water drainage part, quiet school parts; Rotor and the left and right sides shell and the Y-axis support frame frame that are symmetrical in the rotor both sides are installed on the main shaft of said airframe components, and said rotor is provided with spinner blade, and the face that left and right sides shell and rotor are relative is provided with blade; The blade of spinner blade and left and right sides shell is prismatic blade and direction is consistent, and two blades are vertical with rotor plane.Though this utility model patent has enlarged the measured power scope of hydraulic dynamometer, this hydraulic dynamometer can only be measured output power, can not measure the driving power of engine.
Summary of the invention
The technical issues that need to address of the present invention provide a kind ofly can measure the effective output of internal combustion engine and the internal combustion engine dynamometer of driving power.
For solving above-mentioned technical matters; Internal combustion engine Electric Dynamometer of the present invention comprises rotor, and said rotor is connected with the axle of internal combustion engine, has groove on the said rotor; Be provided with belt in the groove and link to each other, be connected with first power meter on the said generator with the runner of generator; Said generator output is connected on the outside resistor, and the connecting line of said generator and external resistor is provided with second power meter.
After adopting said structure,, and be connected with power meter on the generator because the rotor of internal combustion engine circuit dynamometer of the present invention links to each other with generator.Internal combustion engine shaft drives rotor rotation, and the mechanical energy of internal combustion engine is converted into the kinetic energy of rotor, and rotor is converted into kinetic energy the electric energy of generator again.Can measure the mechanical energy of tested internal combustion engine through first power meter on the generator, determine the output power of internal combustion engine.The external resistor that generator was connected to is converted into heat energy with electric energy and distributes, and second power meter on the resistor is through recording the driving power of the energometry machinery of emitting.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
