Technology modification of liquid hydrocarbon fuel

Improving the characteristics of the fuel used immediately before burning is the basis of the technical solution.

What is MT “ECOS’?

MT "ECOS" is not a panacea, but a reliable, simple, inexpensive and effective means to reduce operating costs and the environmental impact in the overall system of environmental safety.МТ.

Testing of the engine

Testing and practical operation of MT “ECOS” in Russia, USA, Czech Republic, China and others, confirmed the consistency and efficiency of the technology, showed an improvement in the completeness and quality of fuel combustion, which allows increasing the efficiency of a power plant, reducing specific fuel consumption and harmful emissions


Our goal

The main goal of fuel modification is to improve the quality of the fuel before it is burned in the combustion chamber, which allows to perform the combustion process most fully and efficiently. It will also improve the performance of systems such as EGR and SCR.

Extension of resource

The resource of operation of the internal combustion engine and power plants, to a large extent, depends on the amount of soot and carbon deposits in the combustion chamber and the exhaust particles formed during incomplete combustion of fuel. MT "ECOS" allows reducing these negative phenomena. Moreover, MT "ECOS" allows cleaning the combustion chambers of soot deposits and thereby extend the service life of the engine and power plants.

ECONOMY - ECOLOGY - RESOURCE - these are the basic requirements today for any engine or power plant.

But all these requirements are interdependent: the improvement of one indicator causes deterioration of another or vice versa. As a result: a compromise!

Industry seeks to produce engines and power plants that meet ever higher technical  and environmental standards, but the ever-increasing amounts of hydrocarbon combustion, the desire to reduce the cost of the final product are forcing consumers to use the cheapest grades of fuel for which modern power plants are not designed. In addition, you must consider the presence of a large number of age-related equipment. This, in turn, leads to environmental degradation, reduction of the lifetime of power plants and other negative consequences. Is it possible, at least partially, to solve these controversial problems without changing the design of the engines and with minimal cost?


Yes. You can: by improving the characteristics of the fuel used immediately before it is burned.

This allows you to make processing technology (modification) of liquid hydrocarbon fuels. This technology dates back to the 80s-90s of the last century: in the process of studying the interaction of hydrocarbons with electric fields, one very important property was revealed: hydrocarbons, interacting with electric fields, change their structure, which leads to an increase in heat of combustion to 5%, and  to save the fuel. Therefore, the task of improving the characteristics of the fuel used immediately before combustion was the basis for the search of  a technical solution.

Any fuel: gasoline, diesel fuel, fuel oil is a mixture of hydrocarbons, a complex group and fractional composition inherent in this type of fuel. In the process of burning, not all, especially heavy, fractions have time to burn in the combustion chamber: they settle on the parts of the cylinder-piston group (CPG), burn down in the exhaust manifold and are released into the atmosphere.

The task of the fuel modification technology is to increase the completeness of the combustion of the fuel that has entered the combustion chamber. This is achieved by treating (modifying) the fuel with electric fields.

As a result of this interaction of the electric field and the fuel, the structure of the fuel, its group and fractional composition (RF patent), and physical properties change. This is confirmed by laboratory studies of the treated fuel (in St. Petersburg NICEB RAS). As a result of this treatment, the number of light fractions with greater heat of combustion increases, and the number of heavy ones with less heat of combustion decreases. The light fractions contain shorter hydrocarbon molecules and, therefore, burn out    to the final products        CO2 and H2O. In addition, the viscosity of the fuel decreases, which leads to an improvement in the quality of mixing and also increases the completeness of combustion of the fuel.

This is confirmed by the bench tests of devices developed on the basis of this technology, carried out in the laboratory of the internal combustion engine of the Peter the Great St. Petersburg Polytechnic University (reports), at the Warsaw Institute of Fuel and Renewable Energy (report) at the Kolomensky Plant OJSC (protocol), on MES booth (USA, Cummins ISX 15.0L 1-6 engine) and others, where the results of previous studies were confirmed and the efficiency of these devices on fuel economy of 3-8% and reduction of  harmful emissions into the atmosphere from working Shimi gases by 15-45% were registered.

The use of fuel modification technology does not violate, but contributes to the improvement of the work of such systems as EGR and SCR used on engines to improve the environment conditions.

About the company



Employees of the company have come a long way in the development and implementation of fuel modification technology. The goal was evident: the creation of inexpensive and effective means to reduce operating costs and environmental impact in 2009-2015 employees of the company together with partners - the Institute of transport problems of the RAS, St. Petersburg Technical University of Peter the Great, St. Petersburg Scientific Center of the Russian Academy of Sciences, Technical University "Voenmekh" - conducted a large research and experimental work on determining the parameters of devices for power plants of various capacities and working on different types of fuel. The devices have been certified in the Russian system (GROWTH P) and according to the requirements of the (RUSSIAN MARITIME REGISTER OF SHIPPING).

In 2015-2018 the company's employees have developed compact, safe and efficient fuel treatment devices, which are called ECOS fuel modifiers (MT ECOS), designed   to work   on the broad variety of various engines and power plants.

Currently, the development and implementation of fuel modifiers (trademark "ECOS") in the Russian Federation is carried out in the company LLC "ECOS". General Director  and  Chief  Designer is Dr. Pavel Anisimov. The company's team continues its research and practical activities.  In Germany, the project is engaged in the implementation by the company



The bench testing of the devices have been carried out on a Peugeot XUD9A diesel engine at the Warsaw Institute of Fuel and Renewable Energy, when the engine was powered with standard diesel fuel, a reduction in the specific emission of СО-10%, HC-40% and PM-15% in the ECE R49 test without changing of NOx emissions rate.

The use of devices when powering the engine with standard diesel fuel with the addition of 10% FAME contributes to an increase in engine power by approximately 4% and to a reduction in the specific emission of CO-35%, HC-50% and PM-45% in the ECE R49 test.

Bench tests at MAHLE Engine Components (MEC, USA) on a Cummins ISX 15.0L 1-6 engine showed a noticeable      decrease in carbon oxides (CO) from 32% to 88%, hydrocarbons (HC) by 38-89% in various modes.

Sea trials of automotive, locomotive and maritime diesel engines conducted in the Russian Federation, the USA, the Czech Republic, China and Germany showed even better results and thus confirmed the results of bench tests of fuel modifiers.

For example, tests of the MAN TGA-18440 brand in the transport enterprise of the joint venture ZAO BALTKOM LINEZ (SP BALTCOM LINES, CJSC, St. Petersburg) showed fuel savings from 6.1% to 17.4%. ( Equipped 70 units of transportation.)

The results of the pilot project in St. Petersburg State Unitary Enterprise Passenger Transport, where 100 city buses were equipped, with “ECOS”             showed a decrease in smoke from 19% to 88%. Equipping the entire fleet of city buses will significantly improve the environmental situation in any large  city.

The test results for reducing fuel consumption on shunting diesel locomotives TEM2 (7.4% -16.2%) and special self-propelled equipment (12.7%) allowed the experts of Russian Railways to evaluate the economic efficiency of MT ECOS with a payback period of 6-8 months.

Currently, new models of devices have been developed taking into account the operating experience of fuel modifiers in water transport and the facilities of JSC Russian Railways, where there is an increased level of vibration and also for installation in power plants of foreign production. All products are certified according to the rules of the EAU.
