Cat to launch dual fuel retrofit kit for 785C truck

Cat's 785C mining truck

Caterpillar will offer its gas blending retrofit kit for the 785C mining truck in 2018.

The OEM’s Dynamic Gas Blending (DGB) technology allows engines to run on both diesel and liquefied natural gas (LNG), offering lower fuel costs while maintaining diesel power and transient performance.

It is the first DGB system Caterpillar has offered for mining machines and will be available for purchase in January 2018 from the global Cat network.

Steve Igoe, Caterpillar’s gas engine business commercial manager, said the company had recently completed validation of the retrofit kit on the 785C mining truck with excellent results.

“The kit will allow customers to reduce fuel costs significantly by using LNG. Natural gas and LNG offer both economic and environmental benefits to the mining industry,” Igoe said.

Caterpillar also plans to offer additional DGB systems in the future. Igoe said the retrofit kit was built on proven Cat DGB technology and had been used in the oil and gas industry since 2013.

“The retrofit kit offers a peak substitution of up to 85 per cent of diesel with natural gas and gets the same performance, reliability and payload as a diesel truck,” Igoe said.

“This will allow our customers to realise a 20 to 40 per cent savings on fuel costs, which can represent millions of dollars each year for a large mine.”
