Project summary

The project goal is to systematize the expertise of the project participants, Russian institutes as well as the international expertise in the design, calculation and design - technology evaluation of the detonation sensors for the integrated control systems of new generation of car engines. The detonation sensor represents an electrical and mechanical converter installed on the engine body and intended for the transformation of the vibration mechanical energy in a given frequency range into the electrical signal that is transmitted to the microprocessor control unit to correct the ignition angle. The detonation sensor allows to improve the operational characteristics of internal combustion engines (increase in power and lifetime) and operational parameters (fuel saving and the possibility to use low octane gas oil).

The project participants are the со - authors of publications in the design of detonation sensors and the only domestic series production detonation sensor for "GAZ - 31029" car. This sensor was also tested on the integrated basis at automobile plants "AvtoVAZ' (Toliatti), "AZLK" (Moscow), "Izhevsk motozavod "(Izhevsk) and was considered to be suitable for the application within the integrated control systems of the engines for new cars of the above plants.

Expected Results

The typed Russian texts of the book will be prepaid containing 120 - 180 A4 pages. Later the book would be published in Russian.

The work results will be scientifically and practically valuable both for the developers of car engines and control systems and for the personnel of technique maintenance centers.

Technical Approach and Methodology

The project work is based on the experience accumulated by the project participants in the development of piezoelectric detonation sensors for the integrated engine control systems.

The project participants have a great experience acquired from the development and design -technology validation of the detonation sensor for "GAZ - 31029 " car.

The project participants have several publications ("Avtomobilnaya promyshlennost," 1994, №9; "Piezotechnika - 94", international scientific - practical conference, Proceedings, Tomsk, edited by ITsP "Tormnform ", 1994 and others) and Russian patents in this field. Some results were presented at the international workshop "Integrated engine injection control systems and sensors" held in Suzdal, Russia) in April 1994.

The book will cover the development, calculation and design - technology validation of piezoelectric detonation sensors of several types wide band, resonance and semi - resonance with a broad bandwidth. The study results will be provided for the detonation phenomenon on some engines; the results were obtained from the analysis of the engine vibrations in various modes.

Potential Role of Foreign Partners

The project participants have several direct contacts with foreign partners under the project 075 - 94 i. e. with the representations of EADQ (Germany) Dr. E. Pridoehl and V. Libig involved in the development of systems and tods for nondestructive control (essentially based on the primary piezoelectric converters). Some results of the detonation sensor development were presented during the visit of the project participants to EADQ Company in April 1995.

The decision about the cooperation with the foreign partners within the proposed project will be taken upon the discussion of the project.
