Engine Size

A new type of high-efficiency reciprocating internal combustion engine — called the “isoengine” — is being developed, which has separate cylinders for compression and combustion. The fully developed engine is predicted to generate electricity at net electrical plant efficiencies of up to 60% with unit sizes in the range of about 5–20 MWe. The specific capital cost and overall engine size are expected to be similar to those of conventional large engines. The construction of a first 3 MW prototype engine has now been fully completed and in October 2002 the first fuel was injected. The present paper focuses on the experience and test results obtained during the commissioning and early test stage of the prototype engine. The testing of this Engineering Demonstrator will contribute significantly to the development of a Commercial Demonstrator and first commercial isoengines, which should be available in the second half of this decade.   NOTE: This paper was presented at the ASME 2003 Internal Combustion Engine Division Spring Technical Conference but was printed in the ASME 2003 Internal Combustion Engine and Rail Transportation Divisions Fall Technical Conference proceedings, pages 409–418.

This paper reviews the options available to the engine manufacturer to comply with US off-highway Tier 3 emissions limits and beyond. The most cost-effective solutions are considered and discussed. Possible technical scenarios for the longer-term development of off-highway engines are reviewed.   NOTE: This paper was presented at the ASME 2003 Internal Combustion Engine Division Spring Technical Conference but was printed in the ASME 2003 Internal Combustion Engine and Rail Transportation Divisions Fall Technical Conference proceedings, pages 419–426.

A new type of high efficiency reciprocating internal combustion engine, which is predicted to achieve an electrical efficiency of up to 60% on diesel fuel or 58% on natural gas, is described with particular focus on the engineering of its novel components. The so-called isoengine, which is being developed by Innogy plc, involves quasi-isothermal compression of combustion air. In commercial applications it is envisaged that the engine will run at 600 rpm and produce 7 MW of electric power. The engine will also be capable of producing up to 3 MW of heat in the form of hot water, with the electrical efficiency reduced by two percentage points. The engine is intended for distributed and on-site power generation with the option of switchable co-generation of hot water for industrial use or for space heating. A 3 MWe engineering demonstrator is currently under construction.

A new layout of a two-cylinder internal combustion engine with counter-pistons is proposed, which increases its efficiency by reducing the pressure angles. The dynamics of the proposed arrangement of a two-shaft crank-slider internal combustion engine, which provides maximum torque moment at maximum gas pressure in the minimum volume of the combustion chamber, is investigated, which reduces the load on the engine design and its weight and dimensional parameters. The research was carried out by comparing the dynamic characteristics of different engines using vector modular models and the KDAM program.

Swing Engine

MFPSE, Micro Free Piston Swing Engine, is a new type of miniature internal combustion engine based on the working principle of two-stroke swing engine. The successful development and operation of this type of miniature internal combustion engine provide important significance for the miniaturization of the internal combustion engine, and provide a number of important research theory, computation method and experimental data. In this article, according to the work characteristics and co-ordination requirements of MFPSE (Micro Free Piston Swing Engine), whose strain interference is analyzed using finite element analysis software, the problems and interference of the center pendulum and cylinder is found evidently. The data of analysis provides theory basis for the MFPSE’s structural optimization, and is critical to improve the performance of MFPSE.
