Diesel generating units require multi-stage viscous oil because the suitable working temperature range of multi-stage viscous oil is wide and the consumption rate is about 30% lower than that of single-stage viscous oil. The performance grade of oil represents the level of oil additives. For heavy-duty engines, the main protective effect is the additives in the oil. As the additives will gradually be consumed over time, only the selection of sufficient grade oil can ensure that the engine can be reliably protected in the whole oil-changing cycle.
The triboelectric effect refers to the charged phenomenon of two different objects due to contact and friction. Generators rely on this triboelectricity effect to obtain electrical energy from the variation of the potential difference between the road surface and vehicle wheels. Generators provide a good way to collect energy that is usually wasted in vain. Friction between tires and the ground consumes about 10% of the vehicle's fuel, which is almost wasted. Therefore, if we can convert it into electricity again, it will greatly improve the fuel efficiency of vehicles.
In high-rise buildings, high-speed diesel generators are generally used. When the units are installed on the floor, that is, not on the bottom floor, the heavy concrete foundation is used to avoid the foundation overweight and increase the floor load. When designing, it is necessary to load the units to the structural specialty. When the unit is located at the bottom of the building, the concrete foundation should be set up according to the requirements of the unit. Bottom angle screw can be buried or installed with an electric drill after the unit arrives.
