The story of Huaxing begins with1968In that year, Heze Oil Pump and Nozzle Factory rose from the wilderness and became one of the early explorers of fuel injection systems for internal combustion engines in China.

However, the wave of market economy is not gentle. In the 1990s, due to outdated equipment, low product quality, and low efficiency, this old state-owned enterprise was on the brink of bankruptcy.

The turning point occurred in 1997. After completing the restructuring of the enterprise, Huaxing people chose the most difficult path - not to buy ready-made foreign technology, but to explore a unique technological route by transforming old equipment and developing new processes.

After more than 20 years of hard training in internal skills, I have achieved remarkable results:

Nowadays, Huaxing has become a national level specialized and innovative "little giant" enterprise and a single champion in the manufacturing industry in Shandong Province.From being on the brink of bankruptcy to becoming an industry champion, Huaxing's path of counterattack is a vivid footnote to the rise of China's manufacturing industry from weakness to strength.

In the field of internal combustion engines, the fuel injection system is one of the core components with the highest technological content and the most demanding machining accuracy.The nozzle diameter, flow coefficient, and atomization effect of the fuel injector directly determine the performance and emission level of the engine.

Huaxing has achieved the top in the industry on this track.

High pressure common rail fuel injector:

Breaking foreign monopolies

The core of the emission upgrade of diesel engines from National III to National VI lies in the transition of the fuel system from mechanical control to electric control. HuaxingIndependently developed electronic high-pressure common rail fuel injector componentsIt is precisely the key to this leap forward.

The technical specifications of this product can be called a 'dance on the tip of the needle':

The difficulty of completing precision machining in a 0.1mm nozzle and ensuring the reliability of hundreds of millions of high-frequency sprays can be imagined. In the past, over 90% of domestic diesel engine manufacturers relied on imports and were expensive. Huaxing has completely broken through foreign technological barriers and product monopolies through independent innovation, achieving domestic substitution.

Gasoline engine direct injection (GDI):

The next blue ocean

After establishing a firm foothold in the diesel field, Huaxing turned its attention to the gasoline engine market. The company is making every effort to promoteResearch and Development of Direct Injection (GDI) Fuel System in Gasoline Engine CylinderThe project successfully applied for Mount Taishan Industrial Leading Talents in Shandong Province for the company, and obtained the provincial government's financial project support fund of 2 million yuan.

This means that Huaxing is moving from a "diesel expert" to a "comprehensive solution provider for fuel systems".

Standard setter:

From 'following' to 'leading'

To measure whether a company truly has industry discourse power, it depends on whether it participates in standard setting.

Diao Yantao, director of Huaxing Experimental Center, also serves as a member of the National Fuel Injection System Standardization Technical Committee. Only in the past three years, Huaxing has led/participated in the formulation4 national standards and 13 industry standardsJB/T14781-2024 "Diesel Electric Control Common Rail System Fuel Injector Parts" was officially released in 2024.

From product localization to standard localization, Huaxing is undergoing a qualitative change from "technology following" to "rule leading".

The manufacturing of fuel injection systems is a typical "high-precision and cutting-edge" field, with almost stringent requirements for processing equipment.

Huaxing's workshop is filled with top-notch equipment from around the world:

Professional equipment with independent intellectual property rights751 unitsAccumulated gainsMore than 100 patents have been authorized by the state.

Meanwhile, Huaxing is under constructionHeavy duty diesel engine common rail system high-tech industrial parkThe total investment amount reaches10 billion yuanAfter completion, the project will have an annual production capacity of 160000 sets of common rail systems.

At Huaxing, behind technological breakthroughs lies the silent perseverance of generations of engineers.

He is committed to promoting the localization of diesel high-pressure common rail fuel systems and gasoline engine direct injection (GDI) fuel systems, breaking through foreign technological monopolies, and helping the domestic automotive and diesel engine industries reduce costs and increase efficiency. The "Annual Production of 600000 Ship High Pressure Common Rail Electronic Control Injector Assembly" project led by him has received a special transfer payment of 1.2 million yuan from the Central Military Civilian Integration Development Fund.

At Huaxing, there are professional technicians like Diao Yantao495 peopleAccounting for nearly one-third of the total number of employees. They have devoted more than 20 years of focus to turning a fuel injector into a "business card" of Chinese manufacturing.
