WIPO Patent Application WO/2004/040130

Kind Code:

A1

Abstract:

An injector (11) is provided such that an injection nozzle (11a) is opposite a suction valve opening (3e), and is set at an angle where a mixture gas of a fuel injected from the injection nozzle (11a) and air produces air motion in a cylinder. The mixture gas is directly injected in a cylinder bore (2b) from the suction valve opening (3e) that is opened during fuel injection from the injector (11), so that the air motion is produced. This reduces the amount of fuel that sticks to a wall face without degrading combustion ability and improves properties of exhaust gases and throttle response.
