Cat’s C7.1 engine redeveloped for less regulated markets

Caterpillar has re-engineered its 7litre C7.1 engine to create a power unit more suited to those markets with lesser-regulated emission controls. Meeting China Stage II emission regulations – equivalent to EU Stage IIIa/EPA Tier 3 – the C7.1 uses high-pressure electronic common rail fuel injection and a wastegated single turbocharger, to achieve a power output of up to 205kW.
