CONSTRUCTION
The pistons are made of aluminum alloy.
Combustion chambers are provided on the pistons for direct injection.
The shape of the combustion chamber has been optimized to achieve a low compression ratio, high engine output, and low fuel consumption.
A cooling channel is provided to achieve excellent piston cooling performance.
To improve the wear resistance of the top ring groove, a Ni-resist cast iron ring carrier is used.
Along with the improved engine performance, the piston skirt is applied with a resin coating to reduce friction loss.
Due to increased machining precision of the cylinder bore diameter, it is not necessary to prepare pistons with different diameters.
