CONSTRUCTION
The cylinder head sub-assembly is made of aluminum alloy. The injector has been located in the center of the combustion chamber in order to improve engine performance and to achieve cleaner emissions.
2 intake ports with different shapes have been combined to promote the mixture of fuel and air by optimizing the swirl in the cylinder.
A vertical 2-stage construction is used for the water jacket to improve cooling performance.
A glow plug is placed between the intake ports of each cylinder to ensure startability.
The cylinder head bolt employs plastic region tightening bolts.
