  "textContent": "A fuel injection system includes an injector (3), a controller (5), and a cylinder internal pressure sensor (26). The injector (3) injects fuel to an engine (1). The controller (5) controls injection start timing (T) of the injector (3), an injection amount (Q), and a supply pressure (P) of the injected fuel. The cylinder internal pressure sensor (26) detects one of a cylinder internal pressure and a heat release rate of the internal combustion engine (1). The controller (5) has a standard estimation means (5) and a correction means (5). The standard state estimation means (5) obtains a standard state of one of the cylinder internal pressure and the heat release rate upon fuel injection from the injector (5). The correction means (5) corrects at least one of the injection start timing (T), the injection amount (Q), and the supply pressure (P) in a direction to eliminate a difference that exists between the standard state obtained by the standard state estimation means (5) and one of the cylinder internal pressure and the heat release rate detected by the cylinder internal pressure sensor (26).",
