ENGINE CONTROL SYSTEM [SKYACTIV-G 2.5]

Outline

• L-jetronic^*1 and D-jetronic^*2 type detectors have been combined for intake air amount detection, improving the accuracy of the intake air amount measurement.

• MAF sensor adopted

• MAP sensor adopted

• IAT sensor No.1 and No.2 adopted

• Valve timing control has been adopted on both sides of the intake and exhaust, improving fuel economy and emission performance.

Intake side: Electric variable valve timing control

• Intake CMP sensor adopted

• Electric variable valve timing motor/driver adopted

• Electric variable valve timing relay adopted

Exhaust side: Hydraulic variable valve timing control

• Exhaust CMP sensor adopted

• Engine oil control has been adopted reducing engine load.

• Engine oil solenoid valve adopted

• With the adoption of the i-ELOOP, charging efficiency during deceleration is improved. (With i-ELOOP)

• DC-DC converter (i-ELOOP) adopted

• With the adoption of fuel pump control, fuel pump power consumption has been reduced, improving fuel economy.

• Fuel pump control module adopted

• Generator output control adopted, fuel economy/idling stability improved.

• Current sensor adopted (with i-ELOOP)

• With the adoption of the ion sensor, which detects pre-ignition, engine reliability has been improved.

• LIN communication has been adopted to the current sensor and DC-DC converter for simplified wiring harnesses.

• With the adoption of the i-ELOOP, charging efficiency during deceleration is improved. Because loss of engine force does not occur when the battery is recharged during deceleration, fuel economy is improved.

^*1

Measures the intake air amount directly using the MAF sensor.

^*2

Measures the intake air pressure introduced into the cylinder using the MAP sensor and calculates the intake air amount indirectly.
