Introduction
The document provides detailed specifications and features of the HiMSEN H17/21V engine, developed by Hyundai Heavy Industries. This engine is Korea's first high-speed engine, designed for marine propulsion, emergency generator sets, and diesel power plants.

Specifications
The H17/21V engine operates at 1,800 rpm (or 1,500 rpm) with a high output of 160 kW (or 140 kW) per cylinder. It features a compact structure, reducing the weight ratio per kilowatt by about one-third compared to current 4-stroke diesel engines. The engine complies with IMO Tier II regulations for emissions and offers low specific fuel oil consumption (SFOC).

Key Features

• High output and low fuel oil consumption.
• Quick acceleration and load response.
• Modularized design for easier maintenance.
• Low NOx emissions and compliance with IMO Tier II.
• Low vibration and noise levels.

Applications
The engine is suitable for both marine and stationary applications, including naval ships, propulsion systems, generating sets, power plants, packaged power stations, and emergency generating sets.

Technical Data
The document provides detailed technical data, including engine output at different speeds (1,500 rpm/50 Hz and 1,800 rpm/60 Hz), dimensions, weights, and specific lubricating oil consumption. The engine's bore and stroke are 170 mm and 210 mm, respectively, with a swept volume of 4.77 liters per cylinder.

Performance Characteristics

• Mean effective pressure (BMEP) is 23.5 bar at 1,500 rpm and 22.4 bar at 1,800 rpm.
• Max firing pressure is 180 bar.
• Power density is 247 b.m/s at 1,500 rpm and 282 b.m/s at 1,800 rpm.

Conclusion
The HiMSEN H17/21V engine represents a significant advancement in earth-friendly engine technology, offering high performance, efficiency, and compliance with international emission standards.
