The ECU calculates a LP-side correction coefficient Kcor_LP and a HP-side correction coefficient Kcor_HP such that they include a LP-side FB correction value Dfb_LP and a HP-side FB correction value Dfb_HP that are calculated using equations (9) and (17) such that an absolute value of an EGR amount error E_egr is reduced, and a LP-side learned value CorMAP_LP/HP-side learned value CorMAP_HP learned when a LP ratio R_LP=1/R_LP=0 holds, calculates a target LP opening θ_LP_dmd and a target HP opening θ_HP_dmd using the LP-side correction coefficient Kcor_LP and the HP-side correction coefficient Kcor_HP, and controls a LP opening θ_LP and a HP opening θ_HP such that they become equal to the target LP opening θ_LP_dmd and the target HP opening θ_HP_dmd.

Combination outlet valve and pressure relief valve and fuel pump using the same
A combination outlet valve and pressure relief valve includes an outer housing having a passage. An inner housing is located within the passage and includes a first bore extending thereinto from one end and a second bore extending thereinto from the other end such that the first bore and the second bore terminate at an inner housing wall. An outlet valve assembly is located within the first bore and includes an outlet valve member, an outlet valve seat, and an outlet valve spring grounded to the inner housing wall and biasing the outlet valve member toward the outlet valve seat. A pressure relief valve assembly is located within the second bore and includes a pressure relief valve member, a pressure relief valve seat, and a pressure relief valve spring grounded to the inner housing wall and biasing the pressure relief valve member toward the pressure relief valve seat.

A fuel injector isolator includes a support member which is rigid and which is annular in shape being centered about an axis such that the support member has a support member inner periphery which circumferentially surrounds the axis and includes a concave region. The fuel injector isolator also includes an isolation member which is resilient and compliant and which is annular in shape being centered about the axis such that the support member has an isolation member outer periphery and an isolation member inner periphery which accommodates the fuel injector therein. The isolation member is located within the support member inner periphery and includes 1) an isolation member outer periphery upper retention surface which engages the support member first end surface and 2) an isolation member outer periphery lower retention surface which extends into the concave region and engages the concave region of the support member.
