C1.1
C1.1 NA and T EU Stage V
DESCRIPTION
The C1.1 and C1.1T are indirect injection industrial diesel engines meeting EU Stage V 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.
