New Puma Energy Tier 3 diesel to lift fuel efficiency of mining fleets

Puma Energy is promising that a new Tier 3 diesel fuel being launched by the company will provide Australian mining companies with a strong improvement in efficiency from their equipment fleets.

The company is introducing the Pumamax Next Gen Diesel, which it says is Australia’s first Tier 3 diesel fuel.

According to Puma, Next Gen will increase fuel efficiency by up to 12 per cent and boost engine performance, while also lowering maintenance costs and emissions.

Puma general manager Ray Taylor said: “During the fuel combustion process, an engine running standard diesel will generally transfer only about 40 per cent of the potential energy contained in a hydrocarbon molecule into mechanical energy.

“This holds back fuel efficiency results for standard or Tier 1 diesel products because they are not completely burned, so any unburnt waste is either deposited in the engine itself or emitted as airborne particles.

“Until recently, the only way to make that process more efficient was to introduce a detergent-like chemical additive to premium diesel fuel, what we call Tier 2 products. While Tier 2 diesel is marginally more efficient, it still does not address the cause of incomplete or uneven burning.”

Puma lead engineer Alex Irvine said the long-term benefits of the new diesel solution have been proven in extensive testing.

“With Next Gen, we have been able to ensure the hydrocarbon chains burn more evenly than ever before. This has the effect of producing quicker, smoother and more powerful flame ignition, propagation and complete burn – much like if you lit a camp fire in several places so the flames can spread and burn faster,” Irvine said.

“What this advancement does is help bring engines back to their original performance levels.”

At the same time, Next Gen provides a protective insulation layer throughout the engine and any associated fuel components, Irvine added. This reduced energy loss allows Next Gen to propel the vehicle further than previously possible.

“In turn, more efficient conversion of the energy stored in Next Gen helps the engine to balance the amount of fuel injected in every power stroke with the power demanded, so fuel consumption is reduced, while decreasing carbon deposits and cleaning the engine beyond the fuel injectors,” Irvine said.

After in-house, on-road and independent testing, Irvine said Next Gen had proven to extend engine component life and maintenance intervals, while cutting maintenance expenses and off-road downtime, as well as curbing greenhouse gas emission and particulate matter discharge.

“We had our road-haulage subsidiary Directhaul fleet do a field test over four months with one of its B-Double trucks and it recorded a 10 per cent saving in fuel costs,” Irvine said.

Next Gen Diesel also reduced and, in most cases, eliminated carbon build-up and engine deposits.
