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.
Fuel Gauge Sender Unit Removal/Installation [2 Wd]
WARNING:
Always keep sparks and flames away from fuel when servicing the fuel system.
Fuel can be easily ignited which could cause serious injury or death, and damage
to equipment.
Fuel line spills and leakage from the pressurized fuel system are dangerous.
Fuel can ignite a ...
Differential Oil Temperature Sensor
Purpose, Function
The differential oil temperature sensor detects the rear differential oil
temperature based on the resistance of the thermistor, and inputs it to the
AWD CM.
Construction
The differential oil temperature sensor is installed in the rear differential
carr ...
Power Brake Unit Inspection
NOTE:
The following inspection methods are simple inspection methods to judge the
function of the power brake unit.
If there is any malfunction in the power brake unit, replace the power brake
unit as a single unit.
