Perkins 403J-11 Engine

The Perkins 403J-11 is a high-performance, ultra-compact, inline-three-cylinder, liquid-cooled diesel engine designed specifically for compact equipment. As a key model in Perkins' advanced 400J industrial power series, the 403J-11 is distinguished by its extremely small footprint, excellent fuel economy, and low noise levels. It meets stringent EU Stage V and US EPA Tier 4 Final emissions standards, making it ideal for space-constrained applications such as mini-excavators, small rollers, turf and landscaping machinery, skid-steer loaders, and mobile lighting towers. Ultra-compact architecture: Featuring an optimized, ultra-short three-cylinder block design, the engine is exceptionally compact and lightweight, allowing for easy installation into the tight engine compartments typical of compact machinery. Clean, efficient combustion: Equipped with an advanced indirect injection combustion system, it fully complies with the world's strictest emissions standards for non-road mobile machinery (EU Stage V / EPA Tier 4 Final), delivering outstanding environmental performance without the need for complex after-treatment systems. Low noise and smooth operation: Precision balancing of the crankshaft and the three-cylinder configuration ensures robust low-speed torque while effectively minimizing operating noise and vibration, significantly enhancing operator comfort.
