Acoustical Resonance Behind Tube Arrays in Exhaust Gas Economizer.

Acoustical Direction Finding with Time-Modulated Arrays

Time-Modulated Linear Arrays (TMLAs) offer useful efficiency savings over conventional phased arrays when applied in parameter estimation applications. The present paper considers the application of TMLAs to acoustic systems and proposes an algorithm for efficiently deriving the arrival angle of a signal. The proposed technique is applied in the frequency domain, where the signal and harmonic c...

Exhaust Gas Recirculation in On·board Diagnostic System

Introduce electronic control exhaust gas recirculation EGR system in the passenger cars and light duty vehicles was made because of fuel direct injectionengines. In this engines temperature combustion process is a higher then other type engine and in this connections NO, emissions were higher to. Simultaneously was appearing problems to electronic exhaust gas recirculation control in connection...
