4-cylinderturbochargedin-line

Overview
The Perkins 404D-22T is a 2.2 litre, 4-cylinder turbocharged industrial diesel engine from the Perkins 400 Series. Designed for off-highway and industrial applications, it balances compact dimensions, refined operation and competitive fuel economy. Available with indirect injection (IDI) and common rail fuel systems to suit varied application requirements.

Features At A Glance

• Low ownership cost – Competitive fuel consumption and engineered reliability reduce lifecycle costs. Warranties: one year for constant-speed and two years for variable-speed models as standard. Global Perkins product support and service network available.
• Compact design – Small footprint and configurable options make the engine suitable for skid steer loaders, mini excavators, wheel loaders, lift platforms, lighting towers, small tractors, air compressors, turf-care and materials-handling equipment.
• Performance and refinement – Smooth power delivery across the 400 Series range (8.2–50 kW) with selective use of indirect and direct injection to deliver low noise and refined operation.
