On December 17, the Award Ceremony for the Third "Rundi Cup" My Reliable Commercial Vehicle Power took place in Beijing. By its outstanding product and market performance, YC6MK won the "My Reliable Power Award" in the heavy-duty category. Zhang Xue, chairman of the Bus Branch of the China Highway & Transportation Society, presented the award to Yuchai's representative.

"As Yuchai's new-generation heavy-duty engine, since its launch, YC6MK has weathered the rigid testing of the market with its quality improved constantly, thus becoming a powerful heavy-duty engine, being widely recognized by vehicle plants and customers, and earning good reputation," Zhong Yuwei, vice general manager of Yuchai Machinery Co., Ltd., said when speaking of the awarded product.

Award represents recognition and motivation

To echo the theme of "My Reliable", like its previous editions, the selection involved three sessions: customer survey, online voting and expert review. The awarded products selected through rigorous evaluation undoubtedly represent the highest technical level of the industry at present.

"With a displacement of 10.3L, YC6MK is a fully-improved and more advanced four-valve heavy-duty engine upgraded and developed on the basis of the original 9.8L model. The series has seven power ranges including 300hp, 340hp, 350hp, 375hp, 385hp, 400hp and 420hp. YC6MK has an integrated cylinder head, improves cooling performance, reduces vibration and noise, and is conducive to controlling emission and increasing reliability. With advantages such as strong power, high reliability, high efficiency, fuel conservation, low noise and environmental friendliness, YC6MK can better meet customers' actual needs," Zhong said.

In terms of power customers are most concerned about, YCMK enhances key parts like body to boost power performance and explosive force, can work under a maximum explosion pressure of 180b, and is fully geared to European high-end heavy-duty engines. With higher reliability and sufficient power reserves, it can meet higher power upgrading demand.

In terms of fuel consumption, YC6MK has better fuel economy. Its intelligent electronically-controlled injection system precisely controls injection timing and injection quantity to boost fuel economy. Besides, the multifunctional economy switch can make the engine operate according to different power curves in different conditions to enhance fuel conservation.

YC6MK's outstanding safety is commendable likewise. The Jake Brake in-cylinder braking system increases the braking force by 55 percent, boosts active safety and makes its braking force more than 10 percent higher than similar products. It can effectively prevent problems like power attenuation, brake failure and off-tracking in rainy days when vehicles run down steep slopes.

Low noise is another prominent advantage of YC6MK. With an integrated cylinder head, it has better air channel consistency, a smoother water channel and a stronger cooling capacity compared to engines with separated cylinder heads. Additionally, it is rigid with small vibration, low noise and highly improved reliability. Besides, four-valve technology boosts the circulation area and efficiency of air intake and exhaust, makes combustion fuller, and fuel consumption and exhaust emission lower. Smoother air intake and exhaust effectively reduces the noise of air intake  and exhaust. The fully optimized piston line and cylinder clearance make the sound of piston click lower, thus effectively controlling noise production, reducing YC6MK's overall noise by 2dB to 4dB compared to similar products and enhancing riding comfort.

High reliability frees customers from worries and reduces use and maintenance cost. The wet cylinder liner is more durable, boosting its useful life; the standard intelligent filter makes engine combustion cleaner and the injection system more durable. You need only to replace the element rather than the shell during maintenance to save worry and money.

It is natural that YC6MK with many outstanding features was recognized by the market. "According to the tendency of the first 11 months, the total sales of YC6MK are expected to be 43,000 units in 2013, including 30,000 truck engines, 4,500 bus engines as well as 8,500 general machinery engines and marine engines. It is primarily carried by heavy-duty engineering trucks and tractors and mainly sold in regions like Southwest, Northwest and North China. YC6MK-powered 12m coaches are sold across the country, earning wide praise from customers," Zhong told cvnews.com.cn, "Outstanding performance and market recognition are both the reasons why YC6MK won the 'My Reliable Power Award" in the heavy-duty category."

For Yuchai, the heavy trophy is just recognition of past efforts as well as motivation for further development.

"'My Reliable Commercial Vehicle Power' is an inspection of a series of work on engine products and manufacturers from technology, production to service. Every vote contains customers' opinions on and expectations of products and enterprises. This also shows the core concept of 'My Reliable Commercial Vehicle Power': being awarded shows products have been highly recognized by the market, but manufacturers should continue maintaining and improving product quality and service. Thus, for me, the award is push and encouragement to engine products and manufacturers. It motivates enterprises to develop engines better meeting customer demand and according with emission regulations and policies in the direction of strong power, energy conservation, low consumption and environmental protection, plays a significant role in encouraging and appealing for industrial energy conservation and emission reduction, and provides effective support for environmental improvement. Of course, awarded engines have provided new orientations and more green choices for purchasers," Zhong said.

Be a model for energy conservation and emission reduction

Every edition of "My Reliable Commercial Vehicle Power" echoed industrial situation. It was the same this year. The biggest highlight was setting the threshold of national IV emission standard.

"According to the emission regulations, the national IV emission standard was originally set to come into effect on January 1, 2011. On December 21, 2010, the implementation time of the national IV emission standard for 3.5t+ diesel vehicles was announced to be postponed till January 1, 2012. Later, the time was further postponed till July 1, 2013. Regardless of how market environment and policies change, Yuchai with deep practice in the bus field has owned strong technical reserves, talent reserves and steady coping strategies. When it was less than three months since the national III standard (equivalent to Euro III standard) came into effect in Beijing and the vast majority of enterprises were prepared for launch of national III products, Yuchai launched China's first national IV diesel engine with independent intellectual property," Zhong introduced.

After year of R & D and improvement, Yuchai has owned all series of diesel engines with complete displacements and power ranges up to the national IV and V standards and partly up to the Euro VI standard. All national IV engines use electronic injection and post-emission processing technologies, all national IV vehicle diesel engines are mass-manufactured, have better power performance and economy, have advantages like large power, low emission, low noise and high reliability, and can meet customers' diverse upgrading demands.

"Yuchai which had sold national IV products in large volume before the national IV standard came into effect has had a lot of customers and strong technical support, the preheated national IV market made us switch to national III and IV emission regulations smoothly. Even so, we had still vigorously promoted the implementation of the national IV emission standard before it came into effect, guiding more customers in using national IV diesel engines based on our existing technical experience and customers' objective feedbacks. Zhong said, "Of course, it is our bounden duty to offer good after-sales service. Yuchai has established over 2,800 service stations and over 4,000 parts sales outlets across the country, and extended its service network to 32 countries in overseas regions like Southeast Asia, Middle East, North Africa, Eastern Europe, Central Asia and Central & South America. The perfect after-sales service network has shortened our service radius, the huge network layout and ever-improved service quality have provided strong support for Yuchai to honor its commitments to customers. As national IV diesel engines are more complex and have higher technical requirements than national III diesel engines, we compiled detailed operation instructions and training materials in diesel engine development, and gave professional trainings to improve the quality of national IV diesel engine service.

A summary of Yuchai's advantages in technology and service shows that Yuchai performed well in the national IV truck and bus segments in the first year of implementation of the national IV diesel engine emission standard, held a large share in all market fields and got off to a flying start.

Strive to be a world leader

The commercial vehicle industry finally ended the drop for two consecutive years to recover slowly in 2013, but confusion and perplexity still hover. At the same time, implementation of the national IV standard and rampant haze has exerted heavy pressure on the high-energy and high-emission commercial vehicle industry.

"In 2013 when domestic and overseas environmental factors are unstable, market competition was fierce and emission regulations were adjusted, thanks to favorable national policies, advanced technologies and the strong after-sales service network, Yuchai grew against the trend. In terms of product technology and quality planning, we further enhanced the technical competitiveness of products, broadened our vision, geared our products to international standards, and stressed competition with the leader in every segment to sharpen the international competitiveness of products," Zhong said.
