READ MOREProduct Features
Gantry-type engine block with rear-mounted gear chamber provides high overall rigidity, low vibration, and low noise.
Four-valve design with one cylinder per head makes operation and maintenance more convenient.
Integrated forged high-strength crankshaft and tooth-shaped high-strength connecting rods offer superior strength and reliability.
Twin-supercharger intake system ensures more efficient and sufficient air intake while maintaining a compact structure and attractive appearance.
Unique dual electronic control system: high-power mode uses electronic high-pressure common rail with multiple injection capability, effectively reducing noise and vibration; low-power mode uses electronic unit pump technology, achieving the perfect combination of high power and cost-effectiveness.
