In this paper. the ignition characteristics in a MICCA-type annular combustor are studied for the first time using a pre-chamber combustion (PCC) system. The PCC is proposed to replace the traditional spark electrode ignitor in the annular combustor. aiming to shorten ignition time and prevent misfiring. https://www.markbroyard.com/quick-sale-savannah-tropic-pure-argan-oil-hair-serum-125ml-oos-on-sale-mega-super/
