Outline
With the adoption of the rocker arm (built into needle roller bearing), the sliding resistance has been reduced.
With the adoption of the HLA, the valve clearance is maintained at 0 mm at all the times.
The contact point of the rocker arm and cam is lubricated by the engine oil injected from the oil shower pipe.
Because the SKYACTIV-G 2.0 is implemented on the Miller cycle, the intake manifold vacuum is insufficient during the intake valve opening timing. To improve this, the intake manifold vacuum insufficiency is supplemented with the adoption of the vacuum pump..
Purpose, Function
The cylinder head forms the combustion chamber and intake and exhaust ports.
Construction
The lightweight cylinder head is made of aluminum alloy with excellent thermal conductivity.
Designing a compact pentroof combustion chamber and positioning the spark plugs on the top of the combustion chamber has improved the combustion efficiency.
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.
High pressurization is achieved by optimizing the intake port shape, improving the tumble ratio, increasing the combustion speed, and suppressing knocking.
With the adoption of plastic region tightening* for the cylinder head bolts, axial force has been stabilized.

Procedure [Plastic Body Parts]
Repair of polypropylene bumpers having damage that has reached the surface of
the polypropylene and are too serious to be restored by painting only.
1. Cut the rough edges around the damage with a knife to make it smooth. Sand
the area with a sander to make an angle of about 45°.
2. ...
Mass Air Flow (MAF) Sensor Inspection
Visual Inspection
1. Remove the MAF sensor/IAT sensor No.1..
2. Visually inspect the MAF sensor for the following:
Damage, cracks, soiling
Rusted sensor terminal
Bent sensor terminal
If there is any malfunction, repair or replace the MAF sensor/IAT sensor
