The invention relates to a device and method for controlling start of compression self-ignition engine. When automatically stopping the engine, an automatic stop controller (51) of an electronic control unit (50) controls the opening of the intake throttle valve (30) so that the intake airflow amount for the compression-stroke-in-stop cylinder (2C) that is on the intake stroke between the final TDC of the cylinder (2C) and the immediate previous TDC (2TDC) of the final TDC increases above the intake airflow amount for the expansion-stroke-in-stop cylinder (2A) that is on the intake stroke between the second previous TDC (3TDC) of the final TDC, and the (2TDC).
