New Generation Flat Motor


SUBARU has presented new generation BOXER engine on 23rd Sep. 2010. Completely new with longer stroke ratio, the value of stroke exceeds that of cylindrical diameter, never served before. Because of width restriction the designing was limited as short stroked flat engine, but this time the engineer overcame this fatal defect to change ordinal common sense,flat design lacks torque because of short stroke.
Judging from small frontal shot, twin cam, not cogged belt but chain connection, water pump driven with rib belt.
Probablly the height of cylinder head has reduced by special design and the height of cylinder block was increased.
Anyway long-awaited motor would be highlighted soon.
But remember the fact that the relatively high frequency noise ,over 2kHz caused by crank shaft vibration and new trans-axle CVT's mechanical construction. As experienced on 3L 6cylinders Legacy, I'm not fond of these 6th sense irritating noise, so the HF noise isolative technology must be invited for newer models.
