Effect of Filtration on Fuel Consumption
The impact of fine abrasives in lube oil as it relates to fuel economy over the engine’s life is noteworthy. A bus engine fuel consumption study by G. Andrews, of the University of Leeds, provides evidence of the benefit associated with cleaner oil on fuel economy in an actual road trial. It was noted that the Cummins engine’s fuel efficiency increased 2 percent to 3 percent when a six-micron by-pass filter was used along with a full flow filter. The study spanned 50,000 miles of service. The fuel consumption was calculated based on detailed fuelling records from the fleet. In a similar study reported by the same authors using by-pass filtration, a 5 percent to 8 percent reduction in fuel consumption was achieved on a 1.8 liter Ford passenger car IDI diesel engine.

KLAROL – Reduces Pollution
KLAROL Oil Cleaning Systems can keep oils clean while the oil is in operation. By keeping oils in operation for a very long time, KLAROL ensures elimination of frequent oil changes. This is a sure shot way of reducing groundwater soil and air pollution, which are possibilities when oil is changed at regular intervals. As discussed earlier, the only way to reduce waste emissions from engines is by ensuring that there is reduced wearing out in engines as they age. When a new engine runs on oil purified by KLAROL it is actually running with a better than new oil at all times. This ensures that while the engine ages it does so with minimum wear. Its oil consumption does not increase over a period of time like in those engines which run without KLAROL. By reducing engine oil consumption KLAROL reduces waste stream emissions in old engines.

Effect of Filtration on Fuel Consumption
A study reported by J. Fodor and F. Ling of the Research Institute of Automotive Industry-Budapest and published in Lubrication Engineering magazine found a sharp improvement in fuel economy in a six-cylinder diesel engine fitted with improved filtration. By reducing oil contamination by 98 percent, not only was a nearly 5 percent reduction in fuel consumption achieved but wear and friction were reduced by 93 percent and 2.9 percent respectively.

KLAROL Reduces Global Warming
Higher fuel consumption means more production of carbon dioxide, a greenhouse gas responsible for increasing Global Warming.

By ensuring that the engine oil is always contaminant free by continuously cleaning it down to less than a micron, by removing water and lighter fractions of fuel and lighter oxidized molecules of oil, and all this while the oil is working in the engine, KLAROL ensures better protection for essential additives in the oil.. Running engine on clean oil at all times and with proper additive protection, not only helps to increase oil life but also ensures an efficient engine over a period of time. A healthy engine ensures better combustion and therefore is more fuel efficient. Better fuel efficiency essentially means lesser production of the greenhouse gas carbon dioxide i.e. reduced global warming.

Ground Water, Soil & Air Pollution
Discarded oil is one of the major sources of pollution. Studies have indicated that mishandling of waste oil can cause ground water pollution, soil pollution and air pollution. Waste oils are carcinogenic and therefore can be injurious to health.

Ideally, waste oil generated should be re-refined and used again. However, studies indicate that a lot waste oil is used for lubricating machines or burnt indiscriminately. Where oil is used for lubricating machines, there are possibilities that this oil finds its way into ground water when shop floors are cleaned. It has been proven that a drop of oil can contaminate a ton of groundwater. Figure below shows engine oil discarded by transporters causing groundwater pollution.

Waste oil can also contaminate groundwater and cause soil pollution during transportation from the site where they are collected to the re-refining plant because of leakages and improper handling. Burning oil can cause air pollution, by releasing hydrocarbons and heavy metals into the air. Engine oils can also cause waste emissions in engines while in operation.



Waste Steam Emissions
When the engine consumes oil, due primarily to contaminant-induced wear, oil enters the combustion chamber, burns with the fuel, and is pushed out with exhaust gases as particles and volatile hydrocarbons. New mineral-based lubricants have a more volatile light-end fraction and are more prone to hydrocarbon emissions. The level of exhaust emissions increases considerably over time corresponding to engine wear and deposit formation in the combustion zone. This leads not only to greater concentration of exhaust particulates, but also to a higher percentage that are unburned hydrocarbon, a by-product of oil consumption.

Unlike a new engine, the lubricating oil is a dominant contributor to particulate matter (PM) emissions in aged engines. The obvious strategy to control / reduce hydrocarbon emissions is to reduce oil consumption. This, of course, points to a strategy of reducing abrasion and wear. According to projections by Barris of Donaldson Co. after 12,000 hours of service, an off-road diesel engine can produce nearly six times more exhaust emissions due to wear associated with particles and other causes.
