Domestic High-pressure Common Rail Breaks Through — BMASTER Shatters Technological Monopoly & Consolidates Industrial Foundation

Fuel injectors and fuel pumps are regarded as the core heart of internal combustion engines, directly determining engine power performance, fuel economy and emission indicators. For a long time, the domestic high-end high-pressure common rail market has been monopolized by international giants such as Bosch and Denso. High pricing and long delivery cycles of imported parts have become a major bottleneck restricting the independent development of the domestic commercial vehicle and construction machinery industries. Thanks to accelerated technological breakthroughs by local manufacturers, domestic high-pressure common rail injectors and pumps have achieved steady market expansion with rising localization rates.

According to the 2023 Blue Book on the Development of Key Internal Combustion Engine Components released by China Automotive Technology and Research Center (CATARC), the installation rate of domestic high-pressure common rail systems in commercial vehicles reached 61.3% in 2022, rising by 15.7 percentage points compared with 2020. The localization rate of core components including injectors and oil pumps exceeded 65%. In terms of technical parameters, the minimum stable injection quantity of domestic common rail injectors has decreased from 1.50 mm³ per stroke in 2021 to 1.20 mm³ per stroke in 2025, with a stable injection pressure above 2000 Bar, reaching the technical level of mainstream mid-range international products.

As a leading domestic manufacturer, BMASTER prioritizes independent research and development. We continuously invest in professional R&D teams and cooperate with domestic scientific research institutions. Targeting China Stage VI b and Off-road China Stage IV emission upgrading requirements, we optimize structural design and precision manufacturing processes. Adopting premium alloy materials, our domestic injectors and pumps undergo strict heat treatment and precision machining. Featuring accurate injection, excellent wear and corrosion resistance and outstanding stability, our products serve as ideal replacements for imported parts, reducing customers’ procurement costs by more than 40%.

To guarantee consistent quality, BMASTER implements a full-process quality control system. Every production procedure from raw material procurement and processing to finished product delivery undergoes rigorous testing, maintaining a product qualification rate above 99.8%. At present, our products are widely applied in light trucks, heavy-duty trucks and construction machinery. We have established long-term partnerships with many domestic OEMs. By breaking the international technological monopoly, BMASTER strengthens the independent and controllable development of China’s internal combustion engine industry.
