After the motorcycle is parked overnight, will you do the warming up for the first riding every day? I believe this is a question for many riders. Some use the motorbike carefully and will warm up for a while before starting, while some impatient riders will start immediately after starting.
However, facts tell us that for a mechanical component or an engine that requires lubrication, preheating is beneficial.
First, warm-up can extend engine life
In winter, the engine oil is generally viscous, and even thinner engine oil cannot avoid the influence from low temperature. After overnight, the oil film on the friction surface of the engine is almost gone. After starting, the engine oil needs pressure to go through the oil passage, reaching each lubricating surface. The process takes some time, especially longer when the oil is viscous. At this time, the importance of preheating is reflected.
Warm-up is to let the engine run at a low speed, and it is not just to warm it up quickly. If the motorcycle is warmed up quickly with the throttle on the spot after starting, because the engine oil has not yet been fully lubricated, this heating method will increase damage and reduce Engine life.
Generally, the oil viscosity decreases in the summer, and the warm-up time is 2 to 3 minutes. In the winter, the oil viscosity increases and the warm-up time is a little longer, 3 to 5 minutes. You can wait for a while after starting, then start lightly, drive at low speed first, and warm the car while driving.
Second, preheating can reduce fuel consumption
For a car in good technical condition, in order to save fuel, the mixing ratio is generally thinner to achieve the purpose of saving fuel. The best condition for adjusting the carburetor of a motorcycle is that the engine speed is the lowest and will not stall when the vehicle is idling, and the engine speed can be responded quickly and smoothly when the throttle is increased or decreased quickly.
The fuel efficiency of a motorcycle is closely related to the degree of atomization of the fuel. The better degree of atomization, the more fully burned and the lower the fuel consumption. The temperature of the preheated combustion chamber is higher, then the flammable mixture entering the combustion chamber is further atomized by its volatility, which the fuel achieves higher efficiency.
With the increasing popularity of EFI vehicles, the demand for pre-heating will decrease apparently, especially in the second aspect mentioned above. EFI vehicles will usually increase appropriately under the feedback of the intake air temperature sensor The injection pulse width is multi-injected to compensate, so the symptoms are not obvious. But generally speaking, no matter what model, proper preheating is always good!
