Introduction of friction loss of energy

In the actual Vibrator Motors, due to various frictional losses will further reduce the actual output power, including the following:

Piston ring and cylinder wall friction. Piston rings are on their own to maintain the effect with the flexibility of the cylinder wall seal. Therefore, the ring wall, that is, when the deformation of piston rings, cylinder piston movement is bound to exist between the cylinder and the friction ring installation, thereby preventing movement of the friction, so deformation of the piston rings needed to increase the load, the friction losses and elasticity the piston ring, ring ring is proportional to the thickness and number of roots.

Oil viscosity and viscosity-temperature characteristics of the friction caused by the loss. Improve the oil viscosity, oil film thickness can be increased, thereby increasing its ability to withstand load and increase the reliability of lubrication. However, the loss will also increase friction, mechanical friction, the friction within the Electric Motor because a very large area, generally in the 0.5 square meters or more.The crankshaft bearings and sliding friction losses.The crankshaft-driven valve and a variety of auxiliary equipment (such as pumps, water pumps, fans, etc.) power loss.

Covered by a layer of oil on these surfaces, when the mechanical movement speed, even a slight increase in oil viscosity, the friction power loss will increase a lot, so the DC motor controller can be reduced using the power, fuel consumption increases. In fact, the number of motorcycle users in order to reduce engine noise, the potential use of high-viscosity oil movement. Oil viscosity, increasing the friction between the components will not only increase the mechanical wear, heat of combustion of fuel, we must enter more friction and power consumption to overcome the increased friction, thereby reducing the engine's effective power. According to trial evidence, the use of SAE-10W30 engine oil SAE-20W50 oil ratio of about 10% higher power consumption. In addition, the lubricating oil viscosity, the cooling effect is relatively worse. This is because the viscosity of the oil flow is slow, behind the cooling effect of natural cooling.
