Cost Effective Maintenance have unveiled a series of products that would improve fuel economy in vehicles. The products include FTC Decarbonizer, Cleanpower, Flushing Oil Concentrate and AW10 antiwear.
Vehicle fuel economy can be improved through operating techniques, improved standard of maintenance and selected use of aftermarket products. There are 3 broad methods that could improve fuel efficiency:
- Improving Combustion Efficiency
- Restoring Lost Efficiency
- Reducing Frictional Horsepower Losses
- Improving combustion efficiency
Engine 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 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 a matter of restoring lost efficiency.
If a fuel additive improves 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 including:
- University Of California, Los Angeles (UCLA)
- Southwest Research Institute, Texas
- WA Institute of Technology
- Curtin University
- Brigham Young University
FTC Decarbonizer’s action is one of chemical catalysis to achieve higher peak flame temperatures and a shorter burn time. For as new automotive (diesel and petrol) applications, fuel economy improves by 2% to 5% depending on engine and operating duty cycle. However, few engines remain in as new condition for long, and this presents opportunities to capitalise on the inefficiencies that are created when an engine first starts to age. Efficiency gains are likely to be of the order 6% to 8%.
Combustion deposits: As engines operate, deposits tend to accumulate with time, particularly in combustion and exhaust spaces. This results in a gradual 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-carbonising effect of FTC Decarbonizer is also a catalytic action, and permits these deposits to be safely burnt off during normal engine operation. FTC Decarbonizer works on the combustion of carbon deposits, by catalytically lowering the combustion temperature of carbon by an estimated 100°C - 150°C, and in so doing restores lost compression, design gas flow and mechanical action that may be impaired by excessive deposits.
Typically fuel economy improvements of 6% to 8% are achieved for engines in sound condition. However, where engines have become badly coked up, fuel economy may have already dropped, and so with restoration of engine cleanliness, can also come some gains in economy.
Engine design efficiency is always best at sustained steady state, high load conditions, so there is always potential for improving fuel economy when engines operate under adverse type conditions, such as 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 decarbonizer.
Fuel system deposits: This is the forte of injector cleaners, although the performance will vary between different products. Engine condition, operation and fuel quality both determine the rate of deposit build up on injectors. Cleanpower from Cost Effective Maintenance provides rapid cleanup of pumps and injectors. It is also 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 ( 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 ( 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 Flushing Oil Concentrate available from Cost Effective Maintenance, 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.
Only a few oil additives are there that deliver energy efficiencies due to their ability to reduce frictional horsepower losses. Cost Effective Maintenance’s entry in this arena is AW10 Antiwear which increases the host oil’s load carrying ability by 2 or more times (depending on the oil).
Falex Test measures the oil load carrying ability. The internationally accepted procedure, Falex test has demonstrated that the active chemical in AW10 antiwear raised the load carrying ability of the base oil. AW10 demonstrates reduced frictional losses and consequent fuel economy.
