The invention discloses an engine injection process control IP (intellectual property) core which is an intellectual property core in a field programmable gate array (FPGA). The IP core specifically comprises an input signal processing module, a high voltage output module, a cylinder gating module and a chopping control module, wherein the input signal processing module is used for converting an input signal into a signal for other module to directly use; the high voltage output module is used for controlling the gating of an external high voltage output circuit; the cylinder gating module is used for gating an oil injection cylinder; and the chopping control module is used for outputting chopper voltage. An IPC (Information Processing Center) device in the engine is designed into specific hardware, namely one IP core in FPGA, so that the invention breaks through the limitation that the traditional single-chip microcomputer operating software algorithm only has serial computing power, and the IP core has the parallel computing power of the hardware of FPGA. On one hand, the design of software codes can be simplified; and on the other hand, the entire IPC device has clear functional architecture, and the reliability of system operation is enhanced.
