Sprinklers can be seen during the summer to spray water on the road, not only to relieve the heat but also to make the road cleaner. What else does the sprinkler do? What else can a sprinkler do? Specifically, this professional car has the following uses. First of all, it can be used to clean the city roads. The main role of the sprinkler is to clean the road surface, especially in northern cities where there is a lot of dust and it has a great influence on the urban environment. For the cleaning of the road surface, not only the solid waste should be disposed of, but also the dust must be treated. Sprinkling water through a sprinkler can effectively suppress this dust and create a good environment for the city. Secondly, spraying water on the road with a sprinkler can relieve the dry weather during summer drought. In summer, the temperature is very high, and the surface temperature is higher than the temperature in the air. This has a certain influence on pedestrians and the urban environment. Watering the pavement can have the effect of lowering temperature and relieving drought. Sprinklers are more efficient in watering, and they are very significant in terms of cooling, which brings people a more appropriate urban environment. Once again, the sprinkler can also be used for greening the city. The sprinkler can also carry out urban greening work because it has a compartment that can hold the water source and can be used to irrigate trees and lawns only by connecting the pipes. For those inconvenient places for water intake, sprinkler trucks are required to complete these greening works, especially for large-scale sprinklers, and the amount of water transported can effectively irrigate trees. Finally, sprinklers can also be used to rescue people in special circumstances. Because the sprinkler has the function of storing water and transporting water, it can also be used to transport water in the event of a sudden fire. It also has certain significance for rescue and disaster relief. However, due to the lack of a power system, the sprinkler has a relatively small head for water, which is not conducive to high-level sprinkler operations and can only complete the task of transportation.

Motorcycle engines work the same way that car engines do. They consist of pistons, a Cylinder Block and a head, which contains the valve train. The pistons move up and down in the cylinder block, driven by explosions of a fuel-air mixture that has been ignited by a spark. Valves open and close to allow the fuel-air mixture to enter the combustion chamber. As the pistons move up and down, they turn a crankshaft, which transforms the energy from the pistons into rotary motion. The rotational force of the crankshaft is transmitted, via the transmission , to the rear wheel of the motorcycle
Motorcycle engines are generally classified by one of three characteristics: the number of cylinders they possess, the capacity of their combustion chambers or the number of strokes in their power cycles.
wheel of the motorcycle.
Cylinders
Motorcycle engines can have between one and six cylinders. For years, the V-twin design was the engine of choice for motorcycle engineers in America, Europe and Japan. The V-twin gets its name from the fact that the two cylinders form a V shape, such as the classic Harley-Davidson V-twin shown below. Notice the 45-degree angle in the Harley-Davidson V-twin-other manufacturers may vary this angle to reduce vibration.
The V-twin is just one way to accommodate two cylinders. When the cylinders are oriented so that the pistons oppose each other, the result is an opposed-twin design. Parallel-twin engines have their pistons placed side by side in an upright position .
Today, the most popular design is the four-cylinder, which runs more smoothly and at higher revolutions per minute (rpms) than a comparable twin. The four cylinders can be placed in a row, or they can be arranged in a V-shape configuration, with two cylinders on each side of the V.
Capacity
The size of the combustion chamber in a motorcycle engine is directly related to its power output. The upper limit is about 1500 cubic centimeters (cc), while the lower limit is about 50 cc. The latter engines are usually found on small motorcycles (mopeds ) that offer 100-miles-to-the-gallon fuel economy but only reach top speeds of 30 to 35 miles per hour.
