THE TURBO FUEL STRATIFIED INJECTION- denotes a type of forced-aspiration(turbo) engine where fuel is force injected into the combustion chamber so as to create a stratified charge.It increases the power and torque of spark ignition engines,makes them economical and reduces the emission to a great extent.
Now what is a stratified charge engine ?-It is a type of internal combustion engine where there fuel is directly fed into the cylinder before ignition.This allows for higher compression ratios and a leaner air-fuel ratio than that of the conventional internal-combustion engines.
Conventionally the internal combustion engines used the Otto-Cycle or the constant volume cycle methodology during the intake stroke.This produces a homogeneous charge which is ignited at the predetermined moment at the beginning of the compression stroke.In the homogeneous charge system the air-fuel ratio is kept very close to stoichiometric,which in other words mean that the air content in the air-fuel mixture is just sufficient for complete combustion.But,the major drawback of this system is that it puts an upper-limit to the engine efficiency,results in unstable combustion which notably impacts the power and emission(especially for that of the nitrogen oxides).
