1.1.1. OMEGA combustion bowl
The OMEGA combustion bowl is a unit designed to perform high-efficiency, low- emission
combustion. As the rim around the combustion bowl port of the upper of the piston has been
machined in a smaller size than the interior of the combustion bowl, strong swirl is produced
in the combustion bowl and strong squish flow makes the fuel be mixed more sufficiently with
air.
Due to the application of OMEGA combustion system and optimal ultilization of intake and
exhaust port configuration within the cylinder head, the DE12 series engines discharge a
very low level of hazardous exhaust gases such as smoke, nitrogen oxide, hydrocarbon, or
carbon monoxide and thus ensure high performance and low fuel consumption.
