MECHANICAL [SKYACTIV-D 2.2]

id0110s5000100


Outline

•  For SKYACTIV-D 2.2, the following is performed to lower fuel consumption.
―  Low compression ratio
•  Combustion efficiency by lower compression ratio (14.0) (fuel injector (2pin type))
•  Combustion efficiency by lower compression ratio (14.4) (fuel injector (6pin type))
―  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. (Fuel injector (2pin type))
•  A maintenance-free design for valve clearance has been achieved with the adoption of the HLA.
