C2.2 China NR4
Cat® C2.2 Diesel Engine
The C2.2 and C2.2T are indirect injection industrial diesel engines meeting China Nonroad Stage IV emission standards without the need for electronic control, aftertreatment or exhaust gas recirculation. Available as naturally aspirated or turbocharged for improved low speed torque, we also offer a range of factory configurable options to minimize the cost of machine development and of manufacturing if equipped with e-controller.
Reliable, Quiet and Durable Power
World-class manufacturing capability and processes coupled with proven core engine designs assure reliability, quiet operation, and many hours of productive life.
High Performance
Substantial torque rise delivers impressive performance throughout a wide speed range while maintaining low operating costs.
Fuel Efficiency
Fuel consumption optimized to match operating cycles of a wide range of equipment and applications while maintaining low operating costs.
Broad Application Range
Industry leading ratings and options for compact construction equipment, material handling, and other industrial applications. The engine is designed to require no special training or operation, which makes it particularly suitable for machines that are used in rental fleets.
Package Size
Ultra-compact package size and high power density ensures ease of installation. It also allows machine manufacturers to develop smaller machines, with low weight for transport, tight turning circles for productivity, and good sight lines for safety.
