Project objective is the development and the agreement with a grant-giving/funding Party of a full-scale (“technology demonstration”) project of a car/vehicle power plant substantiating a 21-century car concept proposal.
STATE OF AFFAIRS IN THE FIELD OF RESEARCH. In the course of a long-time activities of scientific-research institutes and industrial corporations conservatism in both the scientific thought and engineering policy is often worked out. For instance, production and application of internal combustion engines (ICE) with a crank mechanism and a gear box do not permit fuel consumption to be minimized at variable loads.
The best modern automotive engines have the coefficient of efficiency within the limits of 40…45%. Further efficiency increase is limited by conventional use of well-known Otto and Diesel thermodynamic cycles. In doing so, at partial loads effective efficiency decreases from 45% down to 25…20% or even lower, and at idle running effective efficiency becomes as low as zero. At the same time, at full exhaustion of hydrocarbon fuel and while protecting the environment effective efficiency increase of vehicles power plant is the first order for any company producing passenger cars, trucks and etc. The problem in question is evident and it is confirmed by a number of national programs including US National Program Partnership for New Generation of Vehicles (PNGV) [Research program of the partnership for a new generation of vehicles/Second report. National Academy Press. Washington, D.C.1996].
To overcome these stereotypes a technology demonstration project is proposed. Within the project, the development, manufacturing, testing of the operating model of a car power plant device will be performed. This power plant is supposed to provide fuel consumption within the limits of 1,5…2,0 L per a way of 100 km, with a car mass up to 700 kg and reduction of HC, NOx, CO and especially CO2 emissions into the environment.
IMPACT OF THE PROPOSED PROJECT ON PROGRESS IN THE GIVEN FIELD. The implementation of the project will permit to prepare a technology demonstration project with the elaboration of a new thermodynamic cycle theory which will allow to create a principally new ICE with high thermal efficiency and new drives in which energy is generated in the absence of idle strokes.
Project participants competence. The project participants are highly competent persons in the specified area, that is confirmed by their academic degrees and ranks, by a great number of publications and inventions. The weapons scientists and engineers taking part in the project development are persons with long experience in the development of lazer systems for estimate of situation, controlling systems of rocketry and the developments of nuclear power plants for military applications. The project participants have much experience in modeling of physical processes including modeling of power plant processes. On the project topic the participants have more than 30 inventions (some of them were patented in Russia and the USA), 2 reports at conferences (including SAE conference in 1997, the USA), over 20 publications.
EXPECTED RESULTS AND THEIR APPLICATION. Within the project proposal the following results are expected to be obtained:
— The development of design documentation of the proposed power plant variation at the stage of technical proposal. The documentation will be used for the development and agreement with the funding Party (Partner) of a working schedule and estimate of expenditures on this project.
— The development and the agreement with the grant-giving Party (Partner) of a working schedule and estimate of expenditures on the full-scale technology demonstration project.
The task of the project participants is to increase ICE efficiency by means of using the generalized thermodynamic cycle. The development and manufacturing of the proposed pulse/impulse power plant will not require changes of the existing technology in automotive industry as the production/manufacturing of free-piston engines was set in 30–40 years ago and hydraulic equipment is widely practiced in several industries especially in aircraft construction.
Within the project, technology demonstration is supposed to be prepared. For this it is necessary to develop a device of one of the possible construction variations of a car drive with a free-piston pulse/impulse ICE and program-controlled valves. The implementation of the project with manufacturing and testing of the working model of a power plant, will allow to demonstrate advantages of the proposed car concept to a possible Partner and/or a manufacturer and to proceed to commercial realization of the scientific results obtained.
As far as the protection of intellectual property rights and “know-how” are concerned, the participants intend to apply them to concrete inventions and to transfer the rights to the projects of industrial property to other participants of activities in prescribed manner or to a possible Partner.
Meeting ISTC Goals and Objectives:
The implementation of this project:
— Gives weapons scientists and engineers and also the specialists at the Institute of Scientific Cybernetics of the Belarussian National Academy of Sciences to redirect their abilities to peaceful activities by applying their experience and knowledge for the development of a XXI century car power plant.
— Promotes integration of the project participants into the international scientific community as the problem under review is supposed to be actual for the development of transport worldwide.
— Supports basic and applied research and technology development for peaceful purposes, notably in fields of environmental protection, saving of irretrievable energy sources (clearer exhaust, low fuel consumption of a power plant).
— Reinforces the transition of the project team members to the market-based economy as project results will have great commercial potential. Car drives developed on the basis of project results can be demanded by the market-oriented economy i.e. low fuel consumption, decrease of emissions into the environment, low metal requirement, decrease in using of irreparable hydrocarbon raw materials. All these advantages meet the requirements of the mankind.
SCOPE OF WORKS. Project activities are supposed to be carried out of two tasks (in 6 phases).
— development of design documentation for the working model of a power plant at the stage of technical proposal.
— search of additional collaborators; preliminary adjustment of the working schedule, of the technical proposal concerning a power plant with the funding Party (Partner);
— corrections of the technical proposal;
— agreement with the funding Party (Partner);
— proposal developments on the full-scale project, adjustment of the working schedule estimate of expenditures with the funding Party (Partner);
— Introduction of the proposal to ISTC.
THE ROLE OF FOREIGN COLLABORATORS. The collaborators are offered the following forms of participation in the given project proposal:
— information exchange in the course of project implementation;
— providing comments on technical reports;
— cross-checking of the results obtained in the course of the project implementation;
— taking part in the development of the working schedule;
— preliminary evaluation of the proposed power plant for marketing;
— discussing of protection plans of intellectual property.
TECHNICAL APPROACHES AND METHOLOGY. This proposal was preceded by long-lasting investigations. On the basis of mathematical modeling/simulation results the previous study of ICE charts were carried out. Due to the results obtained, the participants received 8 USSR Inventor’s Certificates and 10 patents including a US patent.
The proposal is based on the theory of the generalized thermodynamic cycle for the ICE which uses known thermodynamic processes proved by practice of engine building. The calculations have shown that thermal efficiency of the generalized cycle can reach 70% and effective efficiency 60% compared with 40…45% for the modern diesel engines.
The results of the following investigations and approaches will form the basis of the cycle under development:
— functional analysis of machines;
— system approach to design of machines;
— application of methods of artificial intelligence on synthesis of engine structure and transmission as a whole;
— unitizing of parts of a drive with the help of mathematical modeling/simulation;
— total program control of the engine and transmission.
THE PROJECT FOR TECHNOLOGY DEMONSTRATION will include checking of proper results of scientific investigations by means of design of the operating power plant prototype, its testing and commercial evaluation of the concept under proposal. The project will include the development of:
— the thermodynamic cycle theory with computing of its feasibility and optimization by means of mathematical simulation/modeling;
— elements of one of the possible designs/constructions of a car drive consisting of a free-piston impulse ICE in which the proposed thermodynamic cycle is realized, and a program-controlled hydraulic drive;
— a package of documentation on the working model of a car power plant, manufacturing and testing of this model.
— manufacturing of a working ICE model with a two-stage air compression, a total compression ratio as high as 30…40, and a program-control providing operation of the ICE in impulse mode;
— the project development of a vehicle without a clutch, a gear box with hydraulic impulse transmission and full-drive wheels every of which is program-controlled.
