Rui Power Weichai explores the “killer” of the small horsepower segment of construction machinery

Among them, as a barometer of the construction machinery industry, the excavator has been reflected in its compact development. According to statistics, from January to June 2017, 26 major excavator manufacturers accumulated sales of about 75,000 units, an increase of 100% year-on-year! The small digging sales of 39,549 units, accounting for 52.77%, China's small digging market demand is evident.

Seizing the small-horsepower segment of construction machinery has become an important strategic direction for many companies. As a core power producer, Weichai Power, which launched the Rui Power Series as early as 2015, is also the “killer” for the development of the small horsepower engineering machinery market.

Weichai 4 sharp power construction machinery products

He Weirui’s power, that is, cutting-edge work, making him strong and sharp, cannot be made.

The cutting-edge work: Relying on heavy-duty engine design concept, 70 years of mature product development experience, lasted 4 years, a new design and development of 2-4L products.

Phi Jian Rui Rui: Small-scale power R & D technology frontier masterpiece, leading the development direction of the small power of the Chinese construction machinery industry.

Impossible to be unavoidable: Forge ahead with the spirit of "sharpness and incompatibility" and firmly instigated the belief that Weichai must open up new markets.

The newly designed and newly developed Weichai non-road three-stage construction machinery, which lasted four years, has 2-4L “Rui Power” products, which has accumulated the engine technology accumulation in Weichai in the past 70 years. This "brilliant" work not only satisfies the state's latest requirements in emissions upgrading, but also represents a big leap in performance quality, redefining new standards for small construction machinery market power, and leading the development direction of small power in the Chinese construction machinery industry. .

Relying on Weichai's “Five Countries and Ten Lands” R&D resources, the reliability, dynamics, economy, and NVH of Rui Power have all been significantly improved. Forklifts, skidders, aerial work platforms, small loaders, road rollers Excellent performance in such areas as supporting.

At the beginning of its development, Ruigong Engineering Machinery fully considered the particularity of the environment in which the construction machinery was used. In terms of reliability, Weichai designed and developed "Rui Power" according to the standard of 20,000 hours of life of heavy-duty diesel engine B10. All of them have cylinder liners. By strengthening the body, cylinder head, connecting rod, and crankshaft, the burst pressure easily reaches 16 MPa; Optimize the friction pair, oil pump and oil cooler to increase the oil pressure and reduce the oil temperature so as to realize the good operation of the lubrication system. The BOSCH common rail system, BOSCH urea injection system and BorgWarner are configured based on the excellent supplier system. Turbochargers, silicone oil fans, Petters starters, silver wheel coolers, etc. ensure the high quality of parts.

In terms of dynamics, “Rui Power” continues the traditional advantage of “high torque, high speed, and high power” of Weichai Power's power products. Full MAP torque is significantly higher than that of competing products, and the maximum torque is 7% higher than the competing product. Torque speed The scope is broader.

In terms of economy, through the optimization of combustion, the best matching of supercharger, and the continuous improvement of thermostats, accelerator pedals and other applications, the "Rui-Power" fuel consumption rate is 3-6g/kWh lower than that of competing products.

In NVH, the use of accessories such as high-volume noise reduction fans, muffler boosters, and noise reduction cylinder head covers, as well as constant optimization of combustion noise and mechanical noise, have enabled the “Rui-Power” to achieve higher torque than competing products. , NVH performance is still outstanding. Among them, Weichai WP4.1 was praised as “the quietest engine” when it was applied on trucks.

At the same time, the Weichai non-road three-phase construction machinery power adopts high-pressure common rail technology and standard Weichai autonomous ECU. According to the characteristics of different market segments, it can achieve accurate and customized supporting applications to ensure that the engine and the whole machine can easily play the best status. In addition, at present, Weichai has accumulated more than 10 years in the field of electronic control technology, has 2 million sets of electronically controlled high pressure common rail products, the social possession of the product mature and reliable, and a huge after-sales service, etc., but also enough to allow customers to sit back and relax.

Since Chai Rui Power was listed on the market, it has been recognized by customers and has shown great advantages in continuous use. In the future, under the situation that the demand for small construction machinery is increasing day by day, Weichai will continue to be market-oriented, with the aim of “customer satisfaction”, segment the market, continuously improve the product and market planning, expand the products involved, and hope more customers We can enjoy the excellent quality and meticulous service of Weichai.
