  "textContent": "When a state where combustion injection is carried out under reference target rail pressure obtained by a reference target rail pressure map that is applied in a case where operational conditions and environmental conditions depending on the operational states of an engine are general standard states is shifted to a state where the combustion deteriorates due to a lack of preheating in the cylinder according to fuel injected in a pilot injection, the reference target rail pressure is corrected by decompression so as to set the target rail pressure. Accordingly, this increases the density of heat energy in the combustion field of the fuel injected in the pilot injection so as to achieve a high temperature in the combustion field and prevent an accidental fire caused by the fuel injected in the main injection with adequate preheating maintained in the cylinder.",
