Abstract

<div class="htmlview paragraph">The work evaluates as the adaptation of a torch-ignition system, without charge stratification, in an Otto cycle engine alters the acting curves and also its level of emissions in relation to the motor with original ignition system. For this, based on the literature, three combustion prechamber geometries are projected, built and adapted to a engine FIAT 1581 cm<sup>3</sup>, 4 cylinders, 16 valves modified previously for operation in a cylinder end with development ECU. After accomplishment of the tests it was verified losses in performance and gain in the emissions of CO and CO<sub>2</sub> in comparison with the engine using original ignition system.</div>
