On May 4, 2018, it was learned that the advanced collective and advanced personal nomenclature of May 1st and Employee Skills Competition in Ma'anshan City was held in a grand meeting. The meeting commended the city’s first employee who won the Anhui Provincial Technological Innovation Award, Hanma Gas. The engine project won the third prize and the project leader Lu Lin took office.
Lumin, leader of the Hanma natural gas engine project It is understood that China has become a major global producer and user of internal combustion engines. However, compared with the international advanced level, internal combustion engine products still have large gaps in terms of environmental protection, energy conservation, reliability, dynamic performance, and safety. To solve these problems, The company is autonomously developing the Hanma engine, an environmentally friendly, energy-saving and high-reliability engine for heavy-duty commercial vehicles.
Hanma natural gas engine is mainly designed and developed on the basis of the original Hanma diesel engine. The same technology platform and common parts are the same, and the spare parts supplier is also a world-class company product. Hanma natural gas engine adopts four-valve, integrated cylinder head, wet cylinder liner, overhead camshaft, rear gear train arrangement and electronically controlled gas lean combustion technology, advanced water-cooled turbocharging and efficient post-processing technology, through the national machine Inspections by the authorities such as the EMU Quality Supervision and Inspection Center (Chongqing), EU TUV and AVL Liszt, meet the national five emission standards and have the potential to upgrade to SVI.
Hanma natural gas engine
The main innovations of the Hanma natural gas engine are embodied in the use of an integral cylinder head with double water jackets, which improves the cooling capacity and reliability of the complete machine. The life of the B10 reaches 1.2 million kilometers and is more reliable. The cylinder block adopts a gantry symmetrical belt with a hollow cavity. Structure, improve the body's rigidity, reduce the weight; domestic first integrated design and matching compression release cylinder brake system, braking power up to 80% of positive power, more secure; the main technical indicators reached the international advanced level, products It is environmentally friendly, reliable, safe, low speed and high torque. Hanma Natural Gas Engine has applied for 10 national invention patents, and has authorized 2 items, and 5 items have been entered into practical examinations. Utility models have been declared and 13 items have been authorized, filling the gaps in the province's high-power engines, and having a significant impact on the internal combustion engine technology and industrial development. .
Since it was put on the market in 2016, the Hanma natural gas engine has been widely praised by users and exported to many countries and regions such as Malaysia, which has increased the international influence of China's own brands and achieved remarkable economic and social benefits.
