The combustion chamber consists of the cylinder head and toroidal pistons, hole type injection nozzles and sheathed type glow plugs being installed in the cylinder head.
Combustion occurs when the fuel is directly injected into the combustion chamber with the power operat-ing the piston directly.
The combustion chamber in the Engines 4D30, 4D31, 4D32, 4DR5, 6DR5 is formed by the lobes-shaped main combustion chamber in the piston head and Mitsubishi’s own bell-shaped swirl chamber. A chamber jet is press-fitted into the swirl chamber that is made of material with little thermal expansion and good thermal conductivity. Also installed in the chamber are the sheathed glow plug and throttle injection nozzle.

The upward movement of the piston during the compression stroke imparts a violent swirling motion to the air charged into· the swirl chamber, to which fuel is injected for combustion. As the combustion goes on, the gas moves from the swirl to main combustion chamber where it is mixed with the air present. And further combustion occurs.
