Chongqing Hengtong Chief Engineer Wan Hao: Create a Commercial Vehicle that Meets the National Conditions


Hengtong, a passenger car giant standing in the west, continuously creates eco-friendly, energy-saving, reliable and durable passenger car products for the passenger bus industry in China. In today's global economic downturn, Hengtong Buses has completed its sales target of 3,500 units this year and is moving toward higher goals. With its long-standing gas bus manufacturing experience and rigorous and pragmatic industrial style, Hengtong has provided reliable products for many customers and contributed to the promotion of energy conservation and environmental protection. The reporter recently interviewed Mr. Wan Yu, Chief Engineer of Chongqing Hengtong, to understand the reasons why Hengtong has achieved such success in the past 70 years.

Adhere to Independent Innovation and Cultivate Research Team

When talking about independent innovation, Wan Zong has repeatedly stressed the need to go with Chinese characteristics, especially in the manufacture of dual-fuel passenger cars. If you still take the foreign technology route, it is very likely to lead to dissatisfaction and cause many problems. Nowadays some domestic passenger car factories spend heavily on designing and manufacturing passenger cars to hire foreign design teams. However, this practice is debatable. In practical work, due to various factors, problems in technology matching can be caused. However, if the automaker has its own design team, they can study the design direction according to the country's unique environment and contribute to the maintenance of the entire production line.

Hengtong's achievements in scientific research are not unrelated to Hengtong's “loose” research environment: not only use a lot of financial, material, and human resources, but also carry out strategic cooperation with Chongqing University and Hunan University, and do not severely penalize non-fatal mistakes in the study. It has increased the confidence and motivation of researchers to open up.

Hengtong has a natural gas passenger vehicle research team, there is also a natural gas bus research institute, and its natural gas technology has independent innovation property rights protection. For example, how to solve the problem that the internal cylinder temperature of the engine is too high after burning natural gas;

Over the years, Hengtong has always insisted on independent innovation, which also brought them a lot of Honor. For example, at the beginning of this year's Shanghai BAAV, its Veyron City won the Best Original Bus Award. The homogeneity of Chinese buses is very common. Some passenger cars can easily see which foreign brands are imitated. Therefore, in the field of passenger car manufacturing, we should vigorously promote the spirit of independent innovation.

Improve service network and listen to multiple opinions

Hengtong buses make full use of domestic resources. In addition to their own natural gas R&D capabilities, other assemblies such as the chassis use Dongfeng and other domestic excellent manufacturers' products so that they can rely on their extensive service network. Hengtong and some public transport companies establish after-sales service stations in provincial capital cities, which are conducive to vehicle service in the first place.

In order to better meet the needs of customers, Hengtong listened to opinions from various parties on the bus, such as the driver’s assessment of the condition of the vehicle, and even suggestions from the general public on the comfort of the seats in the compartment, the color requirements, and the brightness of the lights. Mr. Wan Hao gave an example: “Before the development of a new model, related parties from Hengtong organized six seminars before and after the development of the new model. At the end, we performed more than 90 improvements on prototypes and then obtained them during the sales process. Good performance." It can be said that when the new models are off the assembly line, they not only include the technical staff and the hard work of the industry, but also contain the wisdom of many people. If the so-called meet the technical requirements is only debugging in the test site, this may be too one-sided, it can only measure the performance of the bus assembly. Passenger buses, especially buses, are used by the people. From a certain perspective, people at the grassroots level have more say in the products.

About 90% of the buses sold by Hengtong are natural gas buses. Just one day before this article interviewed Mr. Wan Hao, there was exactly one batch of natural gas vehicles exported to Thailand. It is because of the trust in Hengtong's "natural gas" that foreign customers eventually chose them.

Sales is a systematic project. Nowadays, Hengtong has practiced internal strength and has made preparations for passenger car design and development, after-sales service, and spare parts, waiting for customers to review.
