An ECU calculates a command injection amount based on a driving condition, and calculates an injection timing based on a detected fuel pressure. Further, the ECU calculates a provisional injection period, and calculates again an injection period based on the injection timing fuel pressure and the command injection amount when the injection timing fuel pressure is correctly detected.

Process for producing labeled article

A method for producing spiro-orthocarbonate compounds is disclosed. The method comprises reacting a cyclic carbonate compound of the following formula with an epoxy compound containing an epoxy group: ##STR1## wherein R is an alkylene group or a substituted alkylene group. The disclosed method makes it easy to commercially produce spiro-orthocarbonate compounds in a one stage reaction. The starting materials can be easily handled without any hygienic difficulties and the method can be carried out without entailing any operational difficulties.
