2. ENGINE BODY
[1] CYLINDER BLOCK
The 07 series DI engine employs ladder frame
structure type crankcases - the crankcase 1 (1) with
combustion part and the crankcase 2 (2) which supports
the crankcase 1 (1).
The following benefits are in the ladder frame
structure.
1. Minimizing parts.
2. Noise reduction.
3. Reduction of loss and dispersion on friction thanks to
accuracy of axial concentricity.
The cylinder is a linerless type which enables good
cooling operation, less strain and good abrasion
resistance.

[2] COOLING JACKET
The 07 series DI engine employs coolant evenness
distribution type cooling jacket inside crankcase 1. The
coolant is evenly supplied to each cylinder through the
main gallery (3) in the jacket mold core (2).
