<P> In non-diesel internal combustion engines , gasoline direct injection ( GDI ) , also known as petrol direct injection , direct petrol injection , spark - ignited direct injection ( SIDI ) and fuel - stratified injection ( FSI ) , is a variant of fuel injection employed in modern two - stroke and four - stroke gasoline engines . The gasoline is highly pressurized , and injected via a common rail fuel line directly into the combustion chamber of each cylinder , as opposed to conventional multipoint fuel injection that injects fuel into the intake tract or cylinder port . Directly injecting fuel into the combustion chamber requires high - pressure injection , whereas low pressure is used injecting into the intake tract or cylinder port . </P>
