Direct Injection

a method of supplying fuel to the combustion chamber of an internal-combustion engine with internal mixing; the fuel is atomized as it enters the chamber at high speed. Direct injection is achieved by means of manifold fuel feed equipment operating at a maximum injection pressure of up to 100 meganewtons per sq m (MN/m²; 1 MN/m² = 10 kilograms-force per sq cm) or by a pump-and-injector unit at a pressure of up to 200 MN/m². Direct injection is used in diesel engines and in certain types of engines with spark ignition.

No references found			Many car companies are now creating gasoline direct injection (GDI) engines that cut emissions and are more economical than ever - but their reliance on the good old-fashioned spark plug means they still can''t reach optimum perfor mance. Bright sparks gear up; Researchers working to revolutionise ignition ... by Daily Post (Liverpool, England) While similar in theory to "direct-injection" systems, which also inject fuel directly into cylinders, such direct injection systems are difficult to use on small-displacement engines because they require a high-pressure pump that complicates system design, making component layout less cost-efficient.
