The China IV GT17 turbocharger is a precision-engineered performance component designed exclusively for JMC 493 series 2.8L diesel engines meeting China IV emission standards. As a critical powertrain part, it delivers reliable power enhancement and emission compliance for light commercial vehicles, making it the preferred choice for fleet operators, automotive repair workshops and parts distributors worldwide. This turbocharger directly replaces OEM part numbers 1118300ABY and 822158-0002, ensuring perfect fitment and equivalent performance to the original equipment.
The GT17 is a classic turbocharger series developed by Garrett (Honeywell), renowned for its exceptional performance in small to medium flow applications. Specifically calibrated for JMC's JX493 2.8L diesel engine, this China IV variant features an optimized wastegate system that precisely controls boost pressure to meet stringent national emission regulations.
Compressor Housing (Intake Side): The silver-colored upper housing draws in fresh air, which is compressed by the coaxial compressor impeller and delivered to the engine cylinders, significantly increasing air intake volume and combustion efficiency.
Turbine Housing (Exhaust Side): The cast iron lower flange receives high-temperature exhaust gases from the engine, driving the turbine wheel to rotate and power the compressor. This flange is designed for direct mounting to the engine exhaust manifold.
Wastegate Assembly: The side-mounted actuator with connecting rod is the core control component. It automatically adjusts boost pressure based on exhaust gas pressure, preventing over-boost during high engine speeds or heavy loads while optimizing combustion efficiency for China IV emissions.
Oil Inlet/Return Ports: These dedicated ports provide essential lubrication and cooling to the turbine shaft, ensuring stable and long-lasting operation under demanding conditions.
This GT17 turbocharger increases the power output of the naturally aspirated 2.8L 493 engine by approximately 30%. It significantly improves low-end torque, which is crucial for light commercial vehicles carrying heavy loads or operating in urban delivery environments. The optimized boost response ensures smooth acceleration and better drivability across all engine speeds.
Engineered specifically for China IV emission standards, this turbocharger features a precisely calibrated wastegate that maintains consistent boost pressure. This prevents incomplete combustion and works in conjunction with the engine's aftertreatment system to reduce harmful exhaust emissions, ensuring your vehicles remain compliant with environmental regulations.
Constructed with high-quality materials, this turbocharger is built to withstand the harsh operating conditions of commercial diesel engines:
Cast iron turbine housing for exceptional heat resistance
Lightweight aluminum compressor housing for improved efficiency
Precision-balanced rotating assembly for reduced vibration and extended service life
Robust wastegate actuator for consistent performance over time
