ENGINE CONTROL SYSTEM [SKYACTIV-D 2.2]

id0140z7139900

Outline

• Two-step boost control has been adopted, realizing low emission, low fuel consumption, high torque, and high response.

― Compressor bypass solenoid valve adopted

― Regulating solenoid valve adopted

― Wastegate solenoid valve adopted

• Intake stroke EGR using double exhaust valve actuation system (IDEVA) control has been adopted, realizing combustion stability at cold temperatures.

― OCV adopted

• Glow control has been adopted to improve engine startability and diesel particulate filter regeneration performance.

― Glow control module adopted

• Engine hydraulic pressure switching control has been adopted reducing engine load.

― Engine oil solenoid valve adopted

• DC-DC converter control has been adopted for improved power supply stability. (Without i-ELOOP)

― DC-DC converter adopted

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

― DC-DC converter (i-ELOOP) adopted

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

― Current sensor adopted
