Особливості вибору газових форсунок для альтернативного біогазового палива

Abstract

To study the linearity of the work, the reaction time of the nozzle, the resistance of the coil, the operating time, the ability to maintain factory performance and service life, we have selected nozzles of the 4th generation of the most common manufacturers, namely: Matrix; Barracuda; Valtek; Hana; Keihin. According to the results of research, it is established that the linearity of Keihin nozzles will ensure maximum efficiency of biogas combustion on the engine. The reaction time is the highest in Keihin nozzles. Barracuda injectors are very close to Keihin, so their use will not impair engine performance. The factory characteristics of the injectors, namely the coil resistance is optimal in Keihin injectors, and the lowest in Valtek injectors, the reaction time (operation) of Matrix, Hana and Keihin injectors is quite close is 2 ms, which will ensure fast response and operation, and Barracuda injectors Valtek has degraded performance on this parameter, the ability to maintain factory performance in the range of 2 to 5% provide nozzles Keihin, Matrix and Barracuda, and the worst performance in Valtek - up to 20%, the service life of the injectors with timely maintenance is the highest in Keihin nozzles , Matrix and Hana, which is from 200 to 250 thousand km, and the lowest in the Valtek and Matrix injectors resource from 70 to 100 thousand km.
