A szabvany leirasa:
"A combustion chamber design layout of grooves or channels or passages formed in the squish band to further enhance turbulence in the charge prior to ignition as compared to existing designs with squish bands or hemispherical layouts in I.C. Engines. These grooves or channels or passages after ignition direct the flame front to cause multipoint ignition during the combustion cycle resulting in the following distinct advantages over existing designs in practice. First, quicker and complete clean burn combustion; second, lower operating temperatures due to the higher flame velocities; third, enhanced torque and power through the entire range resulting in better fuel economy with lower Emissions; and fourth, smoother engine operation through the entire range enhancing engine life. "

Nem vagyok gepeszmernok, de a sik pres felulet (squish area) nem veletlenul sik.
De az biztos, hogy az eles eleket(khm) kerulni celszeru, igy egy polirozott egesterbe eleg durva beavatkozasnak tunik ez.  Raadasul ezeket esz nelkul vagjak bele, csak ugy saccra.   Vagy bejon vagy nem, de mindenkeppen jol nez ki alapon, gondolom. 

Nekem most lent van a hengerfej a kocsiról, beleflexeljek?  

Találkozott-e már valaki ilyennel, és ha igen, akkor ez mire jó??
