Effect of low temperature on roller

Low temperature makes it difficult to start the engine. The main reasons are the increase of lubricating oil viscosity, the decrease of battery working capacity and the poor atomization of fuel oil.

The viscosity of oil increases with the decrease of temperature, and the flow performance deteriorates, so that the engine lubrication condition deteriorates, and the crankshaft rotation resistance increases.

Battery at low temperature, the viscosity of the electrolyte also increases, the permeability decreases, the internal resistance increases the capacity of the battery and the terminal voltage decreases significantly, even can not discharge. Voltage reduction makes the starter not get the required output power, difficult to meet the requirements of starting speed.

Because the low temperature makes the engine start crankshaft speed is not high, intake pipe temperature and gas flow rate are low, fuel atomization quality is poor, and further increase the difficulty to the engine start.

At low temperature, the viscosity of various oils is large and the fluidity is poor, which brings difficulties to the operation of the roller and aggravates the wear and tear of the parts.

The viscosity of lubricating oil is large, and the power loss of stirring increases when the mechanism is running, so that the power of the engine decreases, and the efficiency of the transmission system is low, thus reducing the driving capacity of the roller walking and exciting mechanism.

The poor fluidity of lubricating oil increases the difficulty of lubricating some parts and reduces the lubrication effect, thus exacerbating the engine and transmission parts wear.

The viscosity of the working oil is large, but also increases the resistance of the pipeline, so that the hydraulic steering is difficult to operate, the efficiency of the hydraulic drive brake deteriorates, increases the difficulty of driving, and has an adverse effect on the safe driving.

There are also common freezing hazards in cold season construction, such as: the freezing of battery electrolyte will make it stop working; The cooling water of a water-cooled engine freezes and cracks the radiator and cylinder block.
