―  Pumping loss improvement from:
•  Variable valve timing mechanism adopted on both sides of intake and exhaust. (SKYACTIV-G 1.5 (with 4-2-1 exhaust system))
•  Variable valve timing structure on intake side adopted (SKYACTIV-G 1.5 (with 4-1 exhaust system))
―  Cooling loss improvement
•  Piston cavity has been adopted.
―  Combustion efficiency improvement
•  Multiple hole-type fuel injectors adopted
•  Cooling loss improvement (with coolant control valve)
―  Coolant control valve adopted
―  Optimized engine coolant passage
•  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. (SKYACTIV-G 1.5 (with 4-2-1 exhaust system))
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*3 has been adopted reducing engine load. (SKYACTIV-G 1.5 (with 4-2-1 exhaust system))
•  Engine oil variable control*4 has been adopted reducing engine load. (SKYACTIV-G 1.5 (with 4-2-1 exhaust system))
―  Engine oil solenoid valve 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
•  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. (See i-ELOOP [i-ELOOP].) (With i-ELOOP)
―  DC-DC converter (i-ELOOP) adopted
•  With the adoption of the ion sensor, which detects pre-ignition, engine reliability has been improved. (SKYACTIV-G 1.5 (with 4-2-1 exhaust system))
•  LIN communication has been adopted to the current sensor and DC-DC converter for simplified wiring harnesses. (Without i-ELOOP)
•  i-stop control has been adopted for improved fuel efficiency, reduced exhaust gas emissions, and reduced idling noise. (With i-stop control)
*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.
*3  :Without coolant control valve
*4  :With coolant control valve
