Engine Mitsubishi 4G93

The 4G93 1834cc GDI engine has the following features. First, gasoline is not injected into the intake manifold, but directly into the combustion chamber. Secondly, the air is fed into the cylinder vertically from the top, and not from the side. This improves the filling of the cylinder and makes it easier to control the air flow. Thirdly, on the 4G93 engine, the piston has a truncated bottom with a spherical recess, which sharply directs the air flow in the opposite direction.
