\u2022 Changes the fuel pressure applied to the fuel injector according to engine operation conditions to improve engine output and startability.<\/div>\n
\u2022 The PCM determines the fuel pressure value corresponding to the engine operation conditions based on each input signal, and drives the spill valve control solenoid valve for optimum control of fuel pressure.<\/div>\n

OPERATION<\/p>\n


<\/p>\n

<\/a><\/p>\n

Directly after engine start<\/p>\n

\n
\n
\u2022 During a cold engine start, the fuel pressure is raised to promote fuel atomization.<\/div>\n<\/dd>\n<\/dl>\n


<\/p>\n

<\/a><\/p>\n

Basic Control<\/p>\n

\n
\n
\u2022 The PCM determines the target fuel pressure according to charging efficiency and performs feedback control by monitoring the fuel pressure in the fuel delivery pipe using the fuel pressure sensor.<\/div>\n
\n
\n
\u2015 When idling after engine warm up: Approx. 10 MPa {102 kgf\/cm 2<\/sup>, 1,450 psi}<\/div>\n
\u2015 After engine warm up, engine speed is 3,000 rpm or less, charging efficiency is 60 % or more: Approx. 20 MPa {204 kgf\/cm 2<\/sup>, 2,091 psi}<\/div>\n
\u2015 After engine warm up, engine speed is 3,500 rpm or more, charging efficiency is 60 % or more: Approx. 25 MPa {255 kgf\/cm 2<\/sup>, 3,626 psi}<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n<\/div>\n
