GAS CA6SN

The GAS CA6SN natural gas engine brings together FAW Jiefang’s extensive diesel engine experience with proven natural gas technology. Drawing from decades of heavy-duty engine development, this 6-cylinder engine tackles the challenge of delivering both power and environmental compliance for today’s commercial vehicle market.

Core Engineering Specifications

Engine Configuration

• Type: 6-cylinder, inline direct injection
• Displacement: 12.53 liters
• Bore × Stroke: 131mm × 155mm
• Valves per cylinder: 4
• Aspiration: Turbocharged with intercooling

Power and Performance

• Power Range: 261-312 kW (350-420 HP) at 1900 rpm
• Maximum Torque: 1500-1650 Nm at 1300 rpm
• Minimum Gas Consumption: 190 g/kWh at full load
• Noise Level: ≤94.6 dB(A)

Advanced Control Technology

The CA6SN uses an electronic control system with closed-loop technology that continuously monitors and adjusts engine operation. This system manages fuel injection timing, air-fuel mixture, and ignition timing automatically, maintaining steady performance whether the engine is under light load or working hard. The result is consistent power delivery with low emissions across different operating conditions.

Environmental Performance

Meeting both Euro IV and Euro V emission standards, the CA6SN produces significantly lower harmful emissions compared to traditional diesel engines. The clean-burning natural gas fuel reduces carbon dioxide emissions by up to 27% while virtually eliminating particulate matter and drastically reducing nitrogen oxide emissions.

Operational Advantages

Cost Efficiency: Natural gas typically costs 40-50% less than diesel fuel, providing substantial operating cost savings. The engine’s efficient combustion system maximizes this economic advantage through optimized fuel consumption rates.

Extended Service Life: Natural gas burns cleananer than diesel, reducing engine wear and extending component life. This translates to longer maintenance intervals and reduced total cost of ownership.

Fuel Flexibility: Designed to work with both compressed natural gas (CNG) and liquefied natural gas (LNG), providing fleet operators flexibility in fuel infrastructure choices.

Applications and Market Fit

The GAS CA6SN excels in heavy-duty applications where environmental regulations are strict and fuel costs matter. Primary applications include:

• Long-haul freight transportation
• Urban delivery vehicles
• Mining operations in environmentally sensitive areas
• Public transportation systems
• Industrial equipment requiring sustained high power

Build Quality and Durability

Manufactured at FAW Jiefang’s state-of-the-art facility in Wuxi, each CA6SN engine undergoes rigorous quality testing. The robust construction features high-strength materials and precision manufacturing processes that ensure reliable operation even under demanding conditions.

Physical Specifications

• Dry Weight: 1050 kg
• Dimensions: 1639mm × 885mm × 1281mm
• Smoke Level: ≤0.3 m⁻¹ at full load

The GAS CA6SN goes beyond being just another fuel option. For fleet operators who need reliable power with lower operating costs and cleaner emissions, this engine offers a practical path forward. It delivers the performance heavy-duty applications demand while helping meet increasingly strict environmental regulations.
