Abstract
Menetelmä polttomoottorin (10) päästöjen vähentämiseksi, joka polttomoottori (10) käsittää ainakin yhden sylinterin (1), edestakaisin liikkuvan, sylinterin (1) sisälle järjestetyn männän (2), imukanavan (3), pakokanavan (4), ainakin yhden imuventtiilin (5) ja ainakin yhden pakoventtiilin (6). Imuventtiili (5) suljetaan imutahdin aikana ennen kuin mäntä (2) saavuttaa alakuolokohdan. Imuventtiilin (5) sulkemisen jälkeen pakoventtiili (6) avataan uudelleen pakokaasun virtaamisen sallimiseksi sylinteriin (1). Ennen pakoventtiilin (6) sulkemista pakokanavaan (4) ruiskutetaan vettä. Keksintö koskee myös polttomoottoria (10).
