연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An engine fuel injection control apparatus includes a variable valve device that at least varies an intake valve open timing of an intake valve. A controller adjusts the variable valve device and a fuel injection timing of a fuel injection valve. The controller controls a fuel injection end timing in accordance with an overlap amount of the intake valve and an exhaust valve. The controller adjusts the fuel injection timing such that the fuel injection end timing is more advanced than the intake valve open timing and such that as an amount by which the overlap amount exceeds a prescribed overlap amount becomes larger, a time interval between the fuel injection end timing and the intake valve open timing is set to become increasingly larger, upon determining that the engine is being cold started and the overlap amount is larger than the prescribed overlap amount.

1. An engine fuel injection control apparatus comprising: an intake port;a fuel injection valve provided in the intake port;a variable valve device that at least varies an intake valve open timing of an intake valve provided downstream of the fuel injection valve; anda controller operatively connected to the variable valve device and the fuel injection valve to adjust the variable valve device and a fuel injection timing of the fuel injection valve,the controller controlling a fuel injection end timing in accordance with an overlap amount of the intake valve and an exhaust valve, andthe controller adjusting the fuel injection timing such that the fuel injection end timing is more advanced than the intake valve open timing and such that as an amount by which the overlap amount exceeds a prescribed overlap amount becomes larger, a time interval between the fuel injection end timing and the intake valve open timing is set to become increasingly larger, upon determining that the engine is being cold started and the overlap amount is larger than the prescribed overlap amount. 2. The engine fuel injection control apparatus as recited in claim 1, wherein the controller adjusts the fuel injection timing such that the fuel injection end timing is more retarded than the intake valve open timing upon determining that the engine is being cold started and the overlap amount is negative. 3. The engine fuel injection control apparatus as recited in claim 1, wherein the controller adjusts the fuel injection timing such that the fuel injection end timing becomes substantially the same as the intake valve open timing upon determining that the engine is being cold started and the overlap amount is a positive overlap amount that is smaller than the prescribed overlap amount. 4. The engine fuel injection control apparatus as recited in claim 1, wherein the controller sets the fuel injection timing such that the fuel injection end timing is fixed at a timing more retarded than the intake valve open timing and not varied according to the overlap amount upon determining that the engine is being cold started and the overlap amount is a positive overlap amount that is smaller than the prescribed overlap amount. 5. The engine fuel injection control apparatus as recited in claim 1, wherein the controller adjusts the fuel injection timing such that the fuel injection end timing is fixed at a timing more advanced than the intake valve open timing and not varied according to the overlap amount upon determining that the engine is being cold started and the overlap amount larger than a second prescribed overlap amount that is larger than the prescribed overlap amount. 6. An engine fuel injection control apparatus comprising: an intake port;a fuel injection valve provided in the intake port;a variable valve device that at least varies an intake valve open timing of an intake valve provided downstream of the fuel injection valve; anda controller operatively connected to the variable valve device and the fuel injection valve to regulate the variable valve device and a fuel injection timing of the fuel injection valve,the controller further including a temperature estimating section that estimates a temperature of the intake valve; anda temperature determining section that determining when a temperature of the intake valve has reached a prescribed temperature at which fuel can be vaporized,the controller controlling a fuel injection end timing in accordance with an overlap amount of the intake valve and an exhaust valve, andthe controller setting the fuel injection timing such that as the overlap amount becomes larger, the fuel injection timing is set to become increasingly more advanced during a period from when the engine is cold started until a temperature of the intake valve reaches the prescribed temperature at which fuel can be vaporized. 7. The engine fuel injection control apparatus as recited in claim 6, wherein the controller sets a fixed close timing for an exhaust valve of the engine. 8. The engine fuel injection control apparatus as recited in claim 6, wherein the controller controls the intake valve open timing such that after a temperature of the intake valve reaches the prescribed temperature at which fuel can be vaporized during cold starting, the controller controls the intake valve open timing such that the overlap amount becomes smaller and sets the fuel injection end timing to be further advanced with respect to the intake valve open timing. 9. An engine fuel injection control apparatus comprising: an intake port;a fuel injection valve provided in the intake port;a variable valve device that at least varies an intake valve open timing of an intake valve provided downstream of the fuel injection valve; anda controller operatively connected to the variable valve device and the fuel injection valve to adjust the variable valve device and a fuel injection timing of the fuel injection valve;the controller further including a blowback amount estimating section that estimates an amount of blown back exhaust gas flowing into the intake port at an open timing of the intake valve,the controller adjusting the variable valve device during cold starting of the engine such that the open timing of the intake valve occurs earlier than a close timing of an exhaust valve, andthe controller controlling the fuel injection timing in accordance with the blowback amount, setting a fuel injection end timing to be more retarded than an open timing of the intake valve upon determining that the blowback amount is zero or smaller than a prescribed value, and setting the fuel injection end timing to occur during an exhaust stroke and at a timing more advanced than a valve open timing of the intake valve upon determining that the blowback amount is larger than a prescribed value. 10.
