A stratified charge engine describes a certain type of internal combustion engine, usually spark ignition (SI) engine that can be used in trucks, automobiles, portable and stationary equipment. The term "stratified charge" refers to the working fluids and fuel vapors entering the cylinder.
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), [1] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold).

fully demand-controlled, (Q7 returnless, RS 4 return to tank); fuel tank–mounted low-pressure fuel pump; Fuel Stratified Injection (FSI): two inlet camshaft double-cam driven single-piston high-pressure injection pumps maintaining a pressure of between 30 and 100 bar (435 and 1,450 psi) in the two stainless steel common rail fuel distributor ...
An all new cylinder head was needed for the Audi-developed Fuel Stratified Injection (FSI), which features cylinder-direct fuel injection straight into the combustion chambers. The result of needing to site both spark plug and fuel injector meant that the former five-valve layout had to be changed to a four-valve-per-cylinder arrangement.
A stratified fluid may be defined as the fluid with density variations in the vertical direction. For example, air and water; both are fluids and if we consider them together then they can be seen as a stratified fluid system. Density variations in the atmosphere profoundly affect the motion of water and air.

Stratified charge compression ignition also relies on temperature and density increase resulting from compression. However, it injects fuel later, during the compression stroke. Combustion occurs at the boundary of the fuel and air, producing higher emissions, but allowing a leaner and higher compression burn, producing greater efficiency.
