ENGINE [SKYACTIV-D 2.2]

id0100000002x6


Special Features

•  For SKYACTIV-D 2.2, the following have been adopted to lower fuel consumption.
―  Low compression ratio
•  Combustion efficiency by lower compression ration (14.0)
―  Weight reductions
•  Aluminum alloy cylinder block adopted
•  Exhaust manifold integrated cylinder heads adopted
―  Weight reduction and mechanical resistance loss improvements
•  Piston shape optimized
•  Narrowed down crankshaft journal
•  The SKYACTIV-D 2.2 has adopted an IDEVA for improved ignition stability during cold engine starts.
•  Two-step boost control has been adopted which realizes low emissions, low fuel consumption and high torque/response by the efficient, high air charging obtained in all ranges.
•  An exhaust gas recirculation (EGR) system has been adopted for cleaner exhaust emissions and improved fuel efficiency.
•  i-stop control has been adopted for improved fuel efficiency, reduced exhaust gas emissions, and reduced idling noise.
•  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. (With i-ELOOP)
