Novel Project in the Brazilian Mining Sector Develops V16 Engine That Uses 70% Ethanol and 30% Diesel. With Over 2,800 HP, Initiative by Cummins, Vale, and Komatsu Promises to Reduce CO₂ Emissions by Up to 70%.

An engine with over 2,800 horsepower, powered by a mixture of ethanol and diesel, is being developed for use in mining. The proposal stems from a partnership between Vale, the Japanese manufacturer Komatsu, and the American company Cummins. The focus is clear: transform the operation of heavy vehicles in Brazilian mines.

The proposal for the flexible engine goes far beyond what we know in automobiles. With superlative size and power, it will be used in off-road trucks that transport hundreds of tons in extreme conditions.

How Does the Flexible Engine in Mining Work?

Called QSK60, Cummins’ engine is a V16 with up to 2,889 horsepower and torque of 1,143 kgfm. The current project adapts this configuration to operate with 70% ethanol and 30% diesel.

Exclusive Project for Operations in Brazil

Although developed at Cummins’ headquarters in Indiana, USA, the engine was designed exclusively for the Brazilian market.

The initiative directly addresses the sustainability needs of domestic mining, especially in Vale operations.

The miner, which has been adopting strict environmental impact reduction goals, sees this project as a technological milestone.

The use of ethanol, an abundant fuel in Brazil, contributes to the policy of promoting renewable sources.

An Engine Outside Conventional Standards

The QSK60 engine weighs 7,794 kg dry, and can reach 9,616 kg with fluids. It will be installed in Komatsu trucks with a maximum operational weight of up to 107,600 kg.

These vehicles reach a maximum speed of only 30 km/h, but are essential for moving tons of ore in rugged terrain.

Unlike passenger car engines, which prioritize speed and lightness, this type of powerplant is designed to withstand, push, and last.

Even at low speed, performance and robustness are crucial in the mining environment.

The Mining Revolution Begins with the Engine

The definition of a flexible engine gains new meaning with Cummins’ project. Focused on sustainability and the safe operation of heavy machinery, the proposal paves the way for cleaner mining in Brazil.

The involvement of giants like Vale and Komatsu adds weight to the project. The expectation is that by 2026, field tests will confirm the viability of the new technology.

While an average building in London or New York takes three years to be completed, in China a 26-story tower went up in five days with about 100 workers, and the global modular construction market already moves US$ 95 billion per year.

Australia installs giant concrete structures on the seabed 800 meters from the shore to create an ocean intake for desalination that will draw in saltwater and produce 30 million liters of drinking water per day.

While cities spend fortunes patching potholes and tons of plastic become waste, the Netherlands transforms over 218,000 recycled cups into a modular bike path that can conceal drainage, cables, and pipes.

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

While communities suffer from water scarcity and the advancing desert, women in Morocco use nets high up in the mountains to trap fog droplets, fill reservoirs, and transport drinking water through more than 10 km of piping.

Goodbye hot wall? The EIFS system uses EPS boards on the outside of the facade, creating a thermal barrier against heat and transforming the external finish into insulation to make houses and buildings more comfortable in the heat.

5 used cars starting from R$ 30,000 with cheap and easy-to-find parts from manufacturers like Fiat, Honda, and Volkswagen deliver up to 120 hp, fuel consumption of 13 km/l, a trunk capacity of 384 liters, and simple maintenance in 2026
