EF115 EFI

Why Choose the HDEF115 EFI?

Flagship Technology, Commercial Standards: Equipped with the same MAPCID precise cylinder detection technology, ECU closed-loop control, and high-temperature, high-altitude, and high-cold-climate tuning as the EF130, the technology is mature and reliable. Major components undergo commercial-grade reinforcement treatment, ensuring outstanding durability. Its advanced engine technology ensures low-noise and low-vibration operation, while industry-leading anti-corrosion technology provides excellent resistance to seawater corrosion.

Highly Efficient and Energy-Saving, Cost-Leading: Optimized combustion efficiency through DOHC 16-valve and integrated exhaust manifold designs, combined with precise control of the intelligent electronic fuel injection system, achieves significant fuel savings under the same operating intensity, bringing long-term economic returns to customers.

Intelligent, Convenient, Safe, and Reliable: Supports NMEA2000 system integration and mobile APP Bluetooth diagnostics, enabling efficient and convenient data monitoring and troubleshooting. A comprehensive ECU warning system monitors key parameters such as water temperature and oil pressure in real time, preventing problems before they occur.

Flexible Adaptability, Global Certification: Offers various models with long and extra-long shafts, and regular rotation and counter rotation, meeting the needs of dual-engine installations and various ship types. Products have passed EU CE and US EPA certifications, complying with environmental regulations in major global markets, and its quality has gained international recognition.

Core Technology Highlights

MAPCID Precise Cylinder Determination Technology: Eliminates the camshaft phase sensor, accurately determining top dead center through manifold pressure to achieve sequential fuel injection (SFI), resulting in more complete combustion and more direct power response.

DOHC (Double Overhead Camshaft) & 16-valve design: Optimizes intake and exhaust efficiency, improves engine power density and low-to-mid-range torque, and adapts to complex operating conditions.

Cylinder head integrated exhaust manifold: Compact structure, significantly shortens warm-up time, quickly enters efficient operating state, and reduces cold friction losses.

Intelligent adaptation to "three high" environments: The electronic fuel injection system is rigorously calibrated to ensure rapid start-up and stable operation in extreme temperatures of -30°C, 50°C, and high altitudes.

Large gearbox and reinforced components: The lower unit drive system is robust and durable, and key moving parts and the suspension system are reinforced to ensure reliability during long-term, high-intensity operation.
