Abstract: PURPOSE: COP(catalyst overheat protection) area is decided in reference of an exhaust gas temperature and a catalyst temperature to adjust fuel amount, thereby improving air fuel ratio. CONSTITUTION: A method for deciding fuel amount feedback control comprises step of deciding whether an exhaust gas temperature is over a certain level. If the exhaust gas temperature is not over the level, it is decided as an air fuel ratio control area, and a feedback control using an oxygen sensor is carried out. If the exhaust gas temperature is over the level, it is decided as a COP area, and mapped fuel amount is injected. If the mapped fuel amount is injected, it is decided whether the exhaust gas temperature is over a certain level again. If then, fuel is more injected, and if not, the fuel is reduced.

Abstract: 본발명의학습영역분리를이용한노킹제어방법에서는전부하와부분부하에서노킹학습셀 구분이이루어지면서동일영역의부분부하노킹학습값이전부하에서도함께적용됨으로써고부하의부분부하에서학습된값으로전부하에서의노킹(Knocking)의발생이최소화되고, 또한부분부하에서특정셀 값의학습시 전부하특정셀도함께학습됨으로써동일영역에서부분부하보다 2ㅀ진각하여맵핑됨에따라부분부하학습값을그대로받아학습하는것이노킹(Knocking)에유리한전부하의특성이반영될수 있으며, 특히점화시기설정방식의다름에도노킹학습제어영역은부분부하와전부하를하나의테이블(Table)로보고맵핑(Mapping)함에따른노킹(Knocking)의악순환이모두해소되는특징을갖는다.
Abstract translation: 在根据本发明的使用学习范围分离的敲击控制方法中，在满负荷和部分负荷下进行敲击学习细胞分离。 由于同一区域的部分负荷敲击学习值一起应用于全负荷，所以在高负载的部分负荷中学习值使满载中的爆震发生最小化。 此外，当在部分负载中学习特定小区值时，一起学习满载中的特定小区值，从而在与部分负载相同的区域中通过2fg进行映射。 因此，可以反映满载的特性，这有利于通过完整地接收部分负载学习值来学习敲击。 更具体地，即使点火正时设定方法不同，敲击学习控制区域将部分负载和满负荷视为表，也可以解决根据映射的恶性循环。

Abstract: PURPOSE: An intake valve is provided to prevent the carbon deposits of the intake valve applied to a gasoline direction injection (GDI) engine by maintaining the temperature of a neck part for connecting a valve head and a valve stem at 200 deg. or less. CONSTITUTION: An intake valve comprises a valve head (3) and a void (4). The valve head is extended from a neck part (2) to open and close an intake passage connected to a combustion chamber. The neck part is formed in one end of a valve stem (1). The void makes an internal space of the valve head in a vacuum state so that heat transferred from the flames of the combustion chamber cannot be transferred to the neck part. The void is concentrically formed with the neck part at the center of the neck part.
