GENERAL DESCRIPTION
- Model Dll46 is 6-cylinder, 4-cycle, in-line, vertical type engines. It is water-cooled and used Toroidal combustion system. 2. 1 Engine Characteristics The engine operates according to the Toroidal combustion system developed by Daewoo Heavy Industrial Co. of Korea and A VL Co. of Austria.
- The main design features of this system are the combustion chamber arranged in the center of the piston and the swirling passage in the cylinder head. Due to the swirling passage, the air entering the cylinder through the helical port designed specially during intake stroke is imparted a strong rotary motion in the combustion chamber and the complicated turbulence motion created by the swirl produced
- during compression stroke and strong squish flow makes the fuel be mixed more sufficiently with air. During power stroke the fuel injected from a multi-orifice nozzle is mixed sufficiently with air for complete combustion, so that the improvement of performance is achieved. Engines with the Toroidal combustion system are characterized by their quiet running, high flexibility and very low specific fuel and oil consumption
