Introduction to SLYD Series Dyno The SLYD dynamometer adopts AC frequency conversion feedback loading, and the loading energy is fed back to the power grid through the AC load generator; the torque and speed are measured directly by the torque sensor; Technical Advantages 1. Energy saving of electric dynamometer: the basic principle of hydraulic and eddy current dynamometer is to convert the mechanical energy generated by the prime mover into heat energy, which will be taken away by water cooling. The energy generated by the prime mover can not be recovered, and energy consumption is also required in the conversion process. However, the electric dynamometer can convert the mechanical energy generated by the prime mover into electrical energy and feed back to the internal power grid for other equipment to use. 2. The loading mode of electric dynamometer: the hydraulic dynamometer can only be loaded in one direction, and the loading performance will be worse when the speed is lower than a certain value; it can not be used as reverse towing equipment, and it needs to be equipped with additional driving equipment when the engine mechanical efficiency test is required. The eddy current dynamometer can be bi-directional loading, but its loading performance is worse than that of hydraulic dynamometer at low speed, so it can not be used as reverse towing equipment. When the engine mechanical efficiency test needs to be done, additional traction equipment should be equipped.

Ozone is a pale blue gas with a distinctively pungent smell. Ozone gas is a powerful oxidant and has many industrial and consumer applications related to oxidation. This same high oxidising potential, however, causes ozone to damage mucous and respiratory tissues in animals, and also tissues in plants, above concentrations of about 100 ppb. This makes ozone a potent respiratory hazard and pollutant near ground level. Ozone gas odour is sharp, reminiscent of chlorine, and detectable by many people at concentrations of as little as 10ppb in air.
