Just as the famous Chinese saying goes, East or west, Guilin landscape is best, Guilins passenger transport enterprises have higher requirements for engine performance than common passenger transport companies. Guilin Junda Transport Co., Ltd. (Junda), Guilins largest road transport enterprise, has 1,527 vehicles for road passenger transport, tourist transport and urban & rural passenger transport, which include 204 publicly-run vehicles and are all used for direct express lines. In the period of National II emission, Jundas direct express lines mainly used import engines, but after the implementation of National III standard in 2008, Yuchai National III engines found its way into part of Jundas direct express lines by its low fuel consumption. From last year, Yuchai National III engines were put into the express system in full swing, with a market share of 100%.

YC6G makes good start

As Jundas quality line brand, express vehicles should run punctually and effectively in perfect conditions, therefore, vehicle performance and prices should be higher than common vehicles, and engine reliability is more demanding. In view of that, during the development of Junda Express, import engines gained an absolute superiority and even held a 100% share at the start-up stage.

However, due to the higher prices of import engines, inconvenient parts purchase and repair services, as well as the technical progress of homemade engines, Yuchai engines fell in the selection scope of Junda. Wu Xiaojie, chief of the Safety Technology Division of Junda, said emotionally, Given the upgrading of engine emission standard, we purchased YC6G engines for a comparative test with import engines in 2006. For the model selection, Wu headed to Yuchai for a survey of technical strength, and was reassured after learning that it is a model developed on the basis of a full set of drawings and production lines introduced from Ford. The results of the actual test have also shown that YC6G is more cost-effective than the two import engines. From the introduction of Ford technical platform in 1992 to successful bus matching in 1998, YC6G has sold well in the industry for a decade. There have been more than 100,000 YC6G engines possessed in the domestic passenger transport market, which enjoys a good fame Yuchai King for its great dynamics and reliability.

The successful trial of YC6G not only offered Junda a good knowledge of homemade National III engine technology and provided a basis for future model selection, but also brought Yuchai engines into Jundas express product system. Subsequently, large-power engines up to National III standard such as YC6L330 and YC6M375 became the matching models for Jundas express vehicles successively.

YC6M becomes new favorite

In 2009, fuel duty was imposed to replace the original road toll, passenger transport surcharge and transport management expense. The original mode of charging by seat number was cancelled, causing a new change to road passenger transport enterprises. Purchasing vehicles with more seats to directly increase operating income has become a fresh need of passenger transport companies. However, it is not necessarily better to have more seats, and once-popular double-deck buses were restricted in many places due to safety concerns in 2009. In this context, half-decked buses have become a new favorite.

"Half-decked buses cater to market demands, and have become the mainstream of Guangxis passenger transport market after being introduced last year. We also purchased six such buses last year, all of which match YC6M375. Wu said, We selected YC6M375 on the basis of Junda Expresss vehicle use facts. Express vehicles are large-sized, run a long distance and have high requirements for engine reserve power. An engine with higher reserve power is more reliable, just as a person who can bear 150 kilograms will walk faster and farther if he bears 50 only.

However, given that YC6M375 is a new model, Junda is conservative in choosing the lines for YC6M375, all of which are in the province: Nanning (a round distance of 800 kilometers), Jinchengjiang (a round distance of 660 kilometers) and Hezhou (a round distance of 500 kilometers). So far, the six YC6M375 engines have served 220,000 kilometers at most and 150,000 at least, with almost no failures found. We are satisfied with a model with such high reliability. Wu said.

The actual integrated fuel consumption of 12-meter half-decked buses with Yuchai engines is about 22L/100km, lower than 25L/100km estimated by Junda. According to the source, compared with another homemade engine, Yuchai engine in the same model has higher reliability and acceleration performance and moderate fuel consumption.

The biggest concern of passenger transport companies is fuel cost. Tire cost, repair cost and fuel cost are Jundas three major costs for daily operation, of which fuel cost accounts for 40% of the total operating cost, far higher than the proportion of tire cost and repair cost. Saving fuel cost by 1% or 2% is considerable. Therefore, Wu values YC6Ms economy most. A year of use reassured Junda. According to Wu, a 12-meter YC6M bus added this year will be put into operation on the longer Guiyang-Guilin line, with Man engine replaced.

Eight-word service motto

Now, more than 90% of Jundas publicly-run and contracted buses are equipped with four & six-cylinder Yuchai engines. If the current trend continues, the figure will hit 100% in one year or two. Wu said. When being asked why he trusted Yuchai so much in an interview with Commercial Vehicle News, Wu replied simply and practically, We chose Yuchai because of its engine quality and service brand. When performance is equal, there is no need to seek far, Yuchais services are best in our eyes, they are always ready. We feel purchasing Yuchai engines is just like purchasing insurance, which frees us from worry. Any problem will be settled by a call.

During cooperation with Yuchai over the decade, Wu could hardly remember how many failures Yuchai has eliminated for Junda, To sum up, Yuchais services are fast, precise, warm and considerate. The reason why Yuchai can reassure customers is that Yuchai has a dense service network. Due to the highly extendable service network, Yuchais service radiuses are intercrossed, and several service outlets will stand by upon receipt of a call. Before engines are deployed, Yuchai have sent staff for follow-up services, carried out staff training and deployed detection equipment.

Wu recollected an important reason for choosing YC6M engines is Yuchais quality services. At Busworld Asia 2008 in Shanghai, Wu specially viewed YC6M engines. The quality of an engine can be judged from appearance and piping, if the appearance is rough and piping is uneven, the engine must be inferior. Because each of the buses equipped with YC6M engines is worth more than RMB 1 million, the company was meticulous in model selection, held a directors meeting with the participation of the chairman, and convened the technical staff of the corporate operation department for discussion. Without any technical reserve or first-hand data, we took a risk on YC6M engines because of Yuchais persistently high quality and considerate services. He said.
