2.1.1.13. The Klapanny mechanism – general information

Fig. 2.20. Klapanny mechanism of engines of the Mazda 3 car: 1–cam-shaft; 2–chain of a drive of the mechanism of a gazoraspredeleniye; 3–camshaft asterisk; 4–lever of a natyazhitel; 5–natyazhitel of a chain; 6–pulley of a cranked shaft; 7–directing to a chain; 8–klapanny knot; 9–cam; 10-the oil operating valve (OCV); 11-executive mechanism of system of change of phases of a gazoraspredeleniye


Each cylinder has two inlet and two final channels. 16 valves are directly put in action by two cam-shafts. On engines of the L3 model the mechanism of change of phases of a gazoraspredeleniye which provides the best moment of opening or closing of valves is used, depending on traffic conditions constantly changing phases of a cam-shaft of inlet channels (fig. 2.20).
