Gujarat Mineral Development Corp. Ltd.
Mr. P.K.Soni (G.M. Project)

“Application of fuel cat has yielded excellent performance in saving of fuel cost in our O & K RH-30 excavators and haulpak 35 tonnage dumpers. Fuel Cat has yielded a saving of 9% approximately in fuel consumption.”

Kandla Port Trust.
Chief Mechanical Engineer

“In Tugs, we have installed it on CATERPILLAR Engines Model CAT – 3516 of 1275 KW (1710 BHP). We have found noticeable improvement in Fuel Efficiency.
This certificate is issued after 8 months of Tests and Trails of Fuel Cats on our Engines. We are satisfied with its performance.”

Irrigation Department – Gujarat State.
Mr. D.A. Thakkar (Executive Engineer, Irrigation Mech. Dn. No. 4)
Mr. K.C. Bharti (Superintending Engineer, Irrigation Mech. Circle No. 2)

“We have fitted fuel cat on our various vehicles and Heavy Equipments like, Ashok Leyland Trailers, Tata Hitachi Excavators, Ashok Leyland Tipper, BEML D-80 Dozers, and Dumpers etc. We have found reduced smoke in emissions and in fuel efficiency.
We have found fuel – Cat kit Environment friendly and Fuel Efficient.”


Understanding Engine Efficiency

It is generally accepted that most Internal Combustion Engines, even when aided with turbochargers and stock efficiency aids, have a Mechanical Efficiency of about 30%.

Most Internal Combustion Engines waste about 31% of the energy in Fuel as heat lost to the cooling system and another 33% through the Exhaust. The rest 6% are friction losses.

Also most of the Combustion process completes in approx. 4-5 miliseconds at an engine speed of 5000 rpm. This is the time that elapses from when the spark is fired until the burning of the fuel air mix is complete after some 80 degrees of crankshaft rotation.

If the fuel is not burnt in given time it results in more Hydro Carbons in Emissions more Carbon deposition on engine walls and wastage of costly fuel energy.

Most Engine manufacturers have done little to harness this wasted energy, though there are very few add-on devices and systems like FUEL-CAT are known to greatly improve Combustion Efficiency and Recover Wasted Energy.

With FUEL-CAT you get the Most Efficient and Energy Saving Combustion, which is Stoichiometric (perfect) Air-Fuel Mixture Ratios where all fuel is consumed giving Maximum Energy Efficiency, and Minimum Generation of Pollutants.
