Diesel engine 403A-15G

3-cylinderin-linefor generator sets

Overview
The Perkins 403A-15G is a 3-cylinder electric power (EP) engine designed for compact generator applications where low noise, high power density and fuel efficiency are required. It is suitable for both unregulated environments with harsh conditions and markets with stricter emissions requirements.

Key Specs

• Gross Mechanical Output: 12.2–15.1 kWm
• Typical Electrical Output: 13.1–16.2 kVA (10.4–12.9 kWe)
• Rated Speed: 1500 rpm
• Emissions: Fuel optimised

Features At A Glance

• Compact and quiet — High power density in a small footprint; engineered for reduced noise levels suitable for urban and noise-sensitive installations.
• Efficient operation — Indirect injection and optimized combustion deliver competitive fuel economy across typical generator duty cycles.
• Low operating complexity — Mechanically governed fuel system and proven components simplify maintenance and reduce running costs.
