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. The engine does not require low ash oils or low sulphur diesel, and service intervals are said to be every 500 hours, according to application.
