Fuel injection apparatus for direct injecting petrol engine in motor car, has high pressure injector arranged in intake tract such that fuel is injected to engine in upstream manner under pressure on inlet valve in closed state

摘要

The apparatus (1) has a high pressure injector (8) comprising an inlet valve (6) discontinuously connected with a combustion chamber (2). The high pressure injector is arranged in an intake tract (7) such that fuel (9) is injected into an internal combustion engine (3) in upstream manner under pressure on the inlet valve in a closed state in adjustable time and crank-angle-related injection duration. Fuel supply is controllable such that the fuel is fed in single interval or in successive intervals in full-load operation of the internal combustion engine. Independent claims are also included for the following: (1) a method for controlling an injection apparatus (2) a computer program including a set of instructions to perform a method for controlling an injection apparatus (3) a motor car.
