Toyota Prado displaying fuel economy

Improving fuel economy

Improving fuel economy can be achieved through operating techniques, improved standard of maintenance and selected use of aftermarket products. When looking at products that could potentially improve fuel economy, there are 3 broad methods of action to consider…

  • Improving Combustion Efficiency
  • Restoring Lost Efficiency
  • Reducing Frictional Horsepower Losses

IMPROVING COMBUSTION EFFICIENCY

Improving fuel economy depends on the peak flame temperature (the higher the better), and the time to complete the combustion process (the shorter the better). It is indeed rare for any fuel additive to produce fuel economy improvements in as new engines, and while it is possible for use of an injector cleaner to result in better economy, it is really a matter of restoring lost efficiency. There would be no change in a new engine which is already clean.

However, if a fuel additive does genuinely improve combustion, it will show an efficiency gain in an “as new” engine, operating under steady state, controlled laboratory conditions. FTC Decarbonizer is one such product that has been validated by numerous world recognized independent testing authorities, a small selection of which include…

University Of California, Los Angeles (UCLA)

Southwest Research Institute, Texas

WA Institute of Technology

Curtin University

Brigham Young University

The most recent validation of FTC  improving fuel economy comes from Australia’s Prof Dongke Zhang in a paper presented to the Asia Pacific Conference on Combustion (2009) in Taiwan. His work was commissioned by BHP Billiton.

FTC’s action is one of chemical catalysis to achieve higher (ie closer to the ideal) peak flame temperatures and a shorter burn time. For as new automotive (diesel and petrol) applications, fuel economy improves by 2-5% depending on engine and operating duty cycle. However, few engines remain in as new condition for long, and this presents opportunities to capitalize on the inefficiencies that are created when an engine first starts to age. Efficiency gains are more likely to be of the order 6-8%, but this introduces another aspect…

Improving fuel economy

Combustion Deposits. As engines operate, deposits tend to accumulate with time, particularly in combustion and exhaust spaces. This results in a gradual, almost imperceptible deterioration of operating performance and economy. These deposits affect economy and performance in several ways. Deposits around piston ring grooves cause fouling of the ring, and even slight fouling results in loss of cylinder compression. In addition, deposits in combustion and exhaust spaces interfere with the smooth efficient flow of gases. Where turbochargers are fitted, the extra weight of any carbon that forms on the turbo blades will slow it down, and reduce supplied air to the engine. General deposits also produce mechanical drag, which further reduces fuel economy.

The de-carbonizing effect of FTC Decarbonizer is also a catalytic action, and permits these deposits to be safely burnt off during normal engine operation. It works on the combustion of carbon deposits, by catalytically lowering the combustion temperature of carbon by an estimated 100-150C, and in so doing restores lost compression, design gas flow and mechanical action that may be impaired by excessive deposits.

The more badly coked up an engine has become, the greater the opportunity to improve (ie restore) fuel economy. Typically fuel economy improvements of 6-8% are achieved for engines in pretty sound condition. However, where engines have become badly coked up, fuel economy may have already dropped dramatically, and so with restoration of engine cleanliness, can also come some amazing gains in economy. I’m reluctant to quote some of the over-the-top sort of cases we’ve had, but there will be one or two examples in our website Case Studies file. Make no mistake, these extreme improvements are not the norm. Many of those engines are either heading for a deposit caused failure, or would benefit by a rebuild.

Engine design efficiency is always best at sustained, steady state, high load conditions, so there is always greater potential for improving fuel economy when engines operate under adverse type conditions, eg stop-start city driving, excessive idling, prolonged light engine loadings, short run times, cool operation

All these operating conditions promote deposit build up, as well as combustion inefficiencies…so there is added potential to improve fuel economy with FTC.

Fuel System Deposits. This is the forte of injector cleaners, although naturally the performance will vary between different products. Engine condition, operation and fuel quality both determine the rate of deposit build up on injectors. Cleanpower is our entry in this category, and it is designed to provide rapid cleanup of pumps and injectors, while being suitable as a routine additive for each fill, to ensure stay clean preventative maintenance.

Crankcase Deposits. For many reasons deposits accumulate in the engine crankcase (ie the oil wetted side of the engine). Quality of engine oil used, service intervals, engine tune, engine duty cycles, fuel system state, turbo performance, top end deposits, type of engine (eg direct or pre-combustion diesel) and more can affect the rate and amount of sludge, carbon and varnish that builds up to cause mechanical inefficiencies, and deteriorated fuel economy.

A restoration (to almost pristine cleanliness) of the crankcase can be achieved using our Flushing Oil Concentrate, and by so doing, operating performance and fuel economy can be restored.

REDUCING FRICTIONAL HP LOSSES

The greater the size, and the number of moving parts, the greater the component mass to put and keep in motion, and the greater are the frictional forces, which consume some of the fuel’s otherwise available power. This applies to engines as well as transmissions and differentials and even hydraulics. What can be done to reduce frictional horsepower losses? The more widespread use of synthetic oils has allowed machinery manufacturers to design engines and transmissions which run on lower viscosity, oils, and that provides  a minor, but important role in progressing efficiencies.

Likewise, if you search amongst the top echelon of oil additives, and there will be a few that deliver energy efficiencies due to their ability to further reduce frictional horsepower losses. Our entry in this arena is AW10 Antiwear which achieves its goal by increasing the host oil’s load carrying ability by 2 or more times (depending on the oil). The means of measuring an oil’s load carrying ability is the Falex Test. This is an internationally accepted procedure, which is used by lubricant manufacturers, and should not be confused with the various test machines demonstrated at field days and such. The Falex test has demonstrated that the active chemical in AW10 dramatically raised the load carrying ability of the base oil. It proved far superior to the ZDDP additive, as used almost universally by major oil blenders. The most interesting aspect is that the Torque required to maintain comparable loadings on the Falex test, was substantially less using AW10 (compared to ZDDP). This clearly demonstrates reduced frictional losses and consequent fuel economy.

Other Falex tests indicated reductions in bearing temperature from 218C to 149C…a 69C drop. Further dramatic evidence of lower friction! Accompanying lower friction and higher load carrying ability is a benefit in reduced wear. Comparing comparable doses of ZDDP and AW10, wear (as measured by weight loss) with AW10 was a mere fraction of that recorded with ZDDP, and unlike ZDDP, the test was completed without seizure of the test components.

Bought Decarbonizer and the Flushing Oil Concentrate to use on my tractor and excavator, sadly a... bit too late for the digger....needs a rebuild. But the tractor was a definite improvement, the engine ran sweeter and a lot less gunk from the exhaust, really noticeable. Thoroughly recommend, the only suggestion is to maybe reconsider the product names....bit confusing. But names are not everything, absolutely worth the money. Many thanksread more

Frankly, I am astounded with the difference. I have been using the FTC Decarbonizer for the last... 1,500k. My mechanic has warned me the engine on my Winnebago Motorhome (Chevy 6.5L turbo diesel, 17 yrs old, 225k on the clock) was exhibiting signs of blow-by. There is now no evidence of smoke from the exhaust under load, the performance has improved, the engine just runs smoother, but incredibly it starts first time after being a difficult starter for several years. I am looking forward to its next service to see what the mechanic has to say. Great product.read more

I have used the AW10 in several cars now. It has made a HUGE difference in all of them. My little... junk Barina that I drive to the train station had a noisy engine and it got hot fast. After using the AW10, it is quiet and the temp takes a while to get to it's working temp. The car runs really well now. All the other cars are running well too.The Rust Conqueror is AMAZING. Works so much better than anything else I have tried. I first saw the XTroll rust treatment way back in the late 80's. It was fantastic back then. Over time I lost the can and moved states. I needed to treat some rust and nothing I used worked properly. I searched for the XTroll and found it with the Cost Effective Maintenance team. They were so helpful. The stuff isn't cheap but it is more than worth it. You want your equipment to last, Use the AW10 and XTroll. Look at the other products too. You won't regret it.read more
