After learning that the new 300 pedal V sharp of Dayang was removed from the line, Niumo.com immediately rushed to the factory to evaluate and test the vehicle. Let’s first talk about its engine.
V 0V took 3 years to form. The chief designer is Mr. Kobe from Japan. He has worked for a well-known Japanese motorcycle company for a long time. After retiring, he went to Beiyi Company as a senior consultant. Through an interview with Mr. Kobe, we have a deeper understanding of the 300-level water-cooled 4-H valve engine independently developed by Dayang. (The following content is compiled according to the interview with Mr. Kobe, and has not been approved by me)
1. Actual displacement 299mlhtml
Looking at the "300-level" large pedals on the market, the actual displacement of most models is not 300ml, and the actual displacement is around 275ml. So strictly speaking, it is not a veritable 300 pedal. The actual displacement of the engine equipped with the Dayang V Rui 300 is 299ml. Judging from the actual displacement, the V Rui is a real 300-level large pedal.
2. The power parameters are leading in the same class
V sharp 300 engine type is water-cooled four-valve, with a maximum power of 20Kw/7500rpm maximum torque of 27.7N.m/6000rpm. The four-valve air intake structure and the advantage of greater actual displacement make its maximum power and torque higher than the same-class models on the market.
Pay attention to the above parameter comparison table. In addition to the maximum power and torque of V sharp is higher than that of competitors, the corresponding output speed is also lower than that of competitors. A relatively lower speed can obtain stronger power output, making daily riding easier, and the engine's durability is relatively better.
3. Multiple imported parts
In order to ensure the performance and quality of the engine, multiple parts inside the engine are imported from abroad or overseas, or foreign-owned enterprises in China, such as DID chains, NTN bearings, INA bearings, NOK oil seals, Pandong and Sanzhixing belts, Taiwan Hongzheng CVT, etc.
4. Double high-position air intake system
double high-position air intake design under the seat.
dual high-position air intake system, two air intake ports are designed under the seat, one for engine air intake, which can effectively filter out hard dust particles in the air, reduce dust wear on the engine, provide sufficient clean air for the engine, and ensure the normal performance of engine power. In addition to dissipating heat to the transmission part, the other air intake also plays a role in preventing wind, sand and wear. Combined with the double-sided toothed belt mentioned below, it can improve the heat dissipation efficiency of the belt and extend the belt life.
5. Double-sided tooth belt
The following figure is a common single-sided tooth belt
Double-sided tooth belt. Traditional scooters are mostly single-sided tooth belt designs. V sharp adopts double-sided tooth design, which can effectively improve the engine's heat dissipation efficiency and extend the service life of the belt. Relatively speaking, the double-sided tooth design has higher requirements on the strength of the belt.
6. bearing shell structure
bearing shell structure, the traditional engine is a bearing transmission structure, the V-sharp engine adopts the commonly used bearing shell structure in high-end multi-cylinder engines, changing rolling friction to sliding friction , effectively reducing friction coefficient , operating more smoothly, with high load and high speed, more suitable for ultra-long distance driving.
In addition, the blades on the Puli disk are designed in reverse. When passing through the wading section, the water can be thrown out to prevent the belt from slipping in and out of water.
also uses mainstream technologies such as automotive-grade filtering.
From the perspective of the engine displacement, power torque and technical content of V sharp, it has excellent hard power and has reached the current level of the first echelon in the same level. So the actual dynamic performance? We will explain this later through long-term testing and professional instrument testing, so please pay attention.
