TECHNICAL FEATURES

HIGH-COMPRESSION ENGINE

OUTLINE

The GX630/GX630R/GX660/GX660R/GX690/GX690R engines have more combustion efficiency and cylinder cooling capability

than previous models. This results in increased the compression (increased to 9.3 from 8.3) and higher engine output.

FEATURE

Combustion efficiency and intake/exhaust efficiency improvement

Combustion efficiency improvement: The S/V ratio (Surface Volume ratio of the combustion chamber) and resulting thermal

efficiency have been increased by making the combustion chamber hemispherical.
The offset distance of the spark plug position has been decreased and the equality of the flame propagation has been increased by

moving the spark plug closer to the center of the combustion chamber.
Intake/exhaust efficiency improvement: Arranging the valves in a radial pattern allows the cylinder to have smoother intake and

exhaust ports, and the port angle has been narrowed.

Cooling efficiency improvement

The cylinder block has been integrated with the cylinder head. It eliminates the use of the low thermal conductivity steel cylinder

head bolts and stainless-steel cylinder head gaskets. Tubes are placed on the outside of the cylinder for push rod passages,

allowing the cylinder block to be thinner and increase cooling efficiency.
