Diesel engine 403D-07G

3-cylinderin-linepower generation

Overview
The Perkins 403D-07G is a 3-cylinder diesel engine designed for compact power generation installations. It combines high power density and fuel efficiency with low noise and refinement, making it suitable for both unregulated (extreme) and higher-regulation territories where emissions standards apply.

Features At A Glance

• Compact and flexible - Small ElectropaK footprint for space-constrained installations; some variants allow speed/frequency switching to match application and territory requirements.
• Efficient, quiet and powerful - 3-cylinder configuration delivers strong power density, good fuel economy and reduced noise levels for urban or noise-sensitive environments.
• Lower operating costs - Simple indirect-injection fuel system, proven reliability, ease of installation and Perkins support reduce total cost of ownership. Common engine platform facilitates affordable upgrades and maintenance.
