GAS 6SF2-17E4N

Advanced Clean Power Technology

The GAS 6SF2-17E4N represents the latest evolution in natural gas engine technology from FAW Jiefang’s renowned Wuxi Diesel Engine Works. This 6-cylinder powerhouse delivers clean, efficient performance that meets today’s demanding environmental standards while maintaining the reliability you expect from commercial-grade engines.

Built with a robust 6.74-liter displacement and advanced turbocharging with intercooling, this engine produces 132 kW of rated power at 2,300 rpm and 125 kW net power. The impressive torque output of 630 Nm at 1,400 rpm ensures strong pulling power for heavy-duty applications, making it perfect for commercial trucks, buses, and industrial equipment.

Clean Emissions and Fuel Efficiency

What sets the GAS 6SF2-17E4N apart is its Euro IV emissions compliance and remarkably low fuel consumption of just 205 g/kW·h. The engine uses a sophisticated electronic control system with closed-loop technology, combined with a specialized natural gas mixer that optimizes the air-fuel mixture for lean burn operation. This results in cleaner combustion, reduced emissions, and better fuel economy compared to traditional diesel engines.

The smoke output stays well below 0.3 m⁻¹, while noise levels remain at or under 98 dB(A), making this engine suitable for urban applications where environmental regulations are strict. Whether you’re running compressed natural gas (CNG) or liquefied natural gas (LNG), this engine adapts seamlessly to different fuel delivery systems.

Proven Engineering Heritage

Manufactured by FAWDE, part of China’s largest heavy truck producer FAW Jiefang, this engine benefits from over 70 years of engineering expertise. The Wuxi facility, established in 1943, now covers 670,000 square meters and produces 600,000 engines annually with world-leading equipment and industry-leading quality standards.

The engine’s compact dimensions of 1,235 × 760 × 950 mm and manageable weight of 600 kg make installation straightforward in various chassis configurations. The direct injection system with precision bore and stroke measurements (107 × 125 mm) ensures optimal combustion chamber geometry for maximum efficiency.

Versatile Applications

This natural gas engine excels in multiple applications where clean power is essential. Heavy-duty trucks benefit from its strong torque characteristics and fuel efficiency, while transit buses appreciate the reduced emissions for city operations. The engine also works well in stationary applications like generator sets, where consistent power output and clean operation are priorities.

The electronic control system constantly monitors and adjusts engine parameters to maintain peak performance across varying load conditions. This smart technology helps extend engine life while maximizing fuel economy and minimizing maintenance requirements.
