FUEL INJECTOR AND IGNITOR FOR INTERNAL COMBUSTION ENGINE

Title:

FUEL INJECTOR AND IGNITOR FOR INTERNAL COMBUSTION ENGINE

Document Type and Number:

Japanese Patent JP2004340124

Kind Code:

A

Abstract:

To provide a stable and low-cost ignition means for a direct injection type internal combustion engine.

In a direct injection spark ignition type internal combustion engine, an electrode 24 is integrally formed with a fuel injection valve 21, and the fuel injection valve 21 has a plurality of fuel injection ports around the electrode 24. Relative disposition of the fuel injection ports 22 in the fuel injection valve 21 and the electrode 24 are preliminarily set, so that no fluctuation is generated while assembled. In the disposition, injected fuel currents 25 are not directly sent to the electrode 24, but fuel mist is securely formed to completely surround the electrode. A ground electrode 23 for this ignitor can be formed on a movable piston 25 in the internal combustion engine.
