Diesel engine 402D-05G

2-cylinderwater coolingTier 3

Overview
Perkins 400 Series electric power (EP) engines provide compact, economical and reliable power for generator sets. The Perkins 402D-05G is the smallest model in the range: a 0.5 litre two-cylinder unit engineered for low running costs, straightforward installation and strong cold-start performance. The engine complies with EU Stage IIIA and U.S. EPA Tier 3 emissions regulations and is suitable for prime and standby applications, including regions with less stringent emissions control.

Features At A Glance

• Lower operating costs — Simple, durable design with 500-hour oil/filter change interval (dependent on load) and a common platform that simplifies upgrades and reduces spare parts costs.
• Small package — Compact dimensions and adaptable component layout ease integration into small genset applications and simplify maintenance.
