Title: a method for LPI engine starting in improvement
Inventor: LEE U JIK
IPC: F02M21/02
Filed: 2002-08-27
Abstract: PURPOSE: A method for improving LPI engine starting is provided to prevent the start ability due to partial cool down in jetting fuel. CONSTITUTION: An engine control unit receives a temperature value of a fuel line for setting up a fuel target pressure(S100-S140). The engine control unit receives the present fuel pressure of the fuel line for operating the same with the fuel target pressure to judge whether the fuel pressure of the fuel line reaches the target fuel pressure(S150,S160). If so, the engine control unit sets the minimum velocity value of a fuel pump for outputting a predetermined control signal to control the fuel pump at the minimum velocity(S170). If not, the engine control unit sets up a fuel pump velocity control value(S180-S200). If the fuel pressure of the fuel line reaches the target fuel pressure, the engine control unit calculates an amount of fuel jet(S300-S380). If the fuel pressure of the fuel line does not reach the target fuel pressure, the engine control unit sets up the maximum velocity control value for outputting a predetermined control signal to control the fuel pump at the maximum velocity(S400-S450).
