Structure & Technical Features
- Cylinder Block & Head: Cast iron block + aluminum alloy head for good heat dissipation and light weight. The cylinder head features an integrated exhaust manifold to improve thermal management efficiency.
- Lubrication & Cooling: Full-pressure lubrication system with a gear-type oil pump, and a water-cooled system with a thermostat for precise temperature control.
- Ignition & Fuel System: Electronic ignition with a distributorless design and multi-point sequential fuel injection, ensuring stable combustion and good fuel economy.
- Noise & Vibration: Optimized crankshaft and balance shaft design, along with a timing chain (or belt) drive system, to reduce NVH (noise, vibration, harshness) and improve durability.
Application & Performance
Typical Applications: Changan Star series, Changan Star Truck, and other small commercial vehicles.
Key Strengths: Compact structure, reliable performance, low fuel consumption, and easy maintenance, making it ideal for urban logistics and light-duty transportation.
Service Life: With proper maintenance, the engine can typically achieve a service life of over 300,000 km.
