C1.1 China NR4
C1.1 NA and T China Nonroad IV
DESCRIPTION
The C1.1 and C1.1T 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-controllerFeatures
- Reliable Power
Manufactured in some of the world's most modern and highly automated production facilities, the Cat® C1.1 is proven to
deliver durable power and offers a wide range of customization options that refuse to compromise quality and durablity. - Compact Size
With a 16.1-21 kW (21.6-28.2 hp) power rating, the C1.1 and the C1.1 turbo allows OEMs to consider different
installation, operating and commercial requirements. These models are particularly adapted to machines where power
from a small package is crucial. And for jobs that require that extra bit of power, there's a turbocharged option that
delivers in almost any condition, at any altitude.
- Quiet Work
The stiff block and indirect injection system make this a quiet engine, minimizing operator fatigue and saving money forOEMs in sound attenuation measures.
