The displacement of the H23 units is 2258 cubic centimeters. The variable valve timing system is carried out using DOHC VTEC technology, developed by Honda engineers. It is equipped with two camshafts with an additional cam that increases pressure on both valves. A toothed belt acts as a drive for the gas distribution mechanism.
