Outline<\/p>\n

\u2022 With the adoption of the rocker arm (built in needle roller bearing), the sliding resistance has been reduced.<\/div>\n
\u2022 With the adoption of the HLA, the valve clearance is maintained at 0 mm {0 in}<\/span> at all times.<\/div>\n
\u2022 The contact point of the rocker arm and cam is lubricated by the engine oil injected from the oil shower pipe.<\/div>\n
\u2022 Because the SKYACTIV-G 2.0 and SKYACTIV-G 2.5 are implemented on the Miller cycle, the intake manifold vacuum is insufficient during retarded intake valve closing. To improve this, a vacuum pump has been adopted which compensates for the insufficient intake manifold vacuum. (See VACUUM PUMP [(US)]<\/a>.)<\/p>\n\n\n\n

Purpose, Function<\/p>\n

\u2022 The cylinder head forms the combustion chamber and intake and exhaust ports.<\/div>\n



\n<\/a><\/p>\n

Construction<\/p>\n

\u2022 The lightweight cylinder head is made of aluminum alloy with excellent thermal conductivity.<\/div>\n
\u2022 Designing a compact pentroof combustion chamber and positioning the spark plug on the top of the combustion chamber has improved the combustion efficiency.<\/div>\n
\u2022 There are two intake valves and two exhaust valves per cylinder for a total of four valves and the intake\/exhaust type has been changed to a cross-flow type, improving intake and exhaust efficiency.<\/div>\n
\u2022 High pressurization is achieved by optimizing the intake port shape, improving the tumble ratio, increasing the combustion speed, and suppressing knocking.<\/div>\n
\u2022 With the adoption of plastic region tightening *<\/sup> for the cylinder head bolts, axial force has been stabilized.<\/p>\n\n\n\n

*:Plastic region tightening is a method of controlling the tightening using the rotation angle of a bolt and suppressing the variations in the axial force by tightening the bolt until its deformation does not return to its original condition (plastic region).<\/div>\n<\/div>\n
