Diesel engine 403A-11G

3-cylinderin-linepower generation

Overview
The 403A-11G EP diesel engine is a compact 3-cylinder power unit designed for industrial power generation applications. It delivers high power density, efficient fuel consumption and low noise for installations where space, emissions tuning and reliable electrical output are priorities.

Features At A Glance

• Compact and flexible – ElectropaK packaging minimises footprint; suitable where size constraints and aftertreatment integration are considerations. Certain configurations support matching of engine speed and electrical frequency to application requirements.
• Efficient, quiet and powerful – Three-cylinder layout provides strong power-to-weight ratio, improved refinement and low operational noise, appropriate for urban and sensitive environments.
• Lower operating costs – Simple indirect injection fuel system, proven mechanical governance and straightforward installation reduce maintenance burden and total cost of ownership.

Key specifications
