Abstract
A start control device of a vehicular direct injection engine provided in a vehicle is configured to execute an ignition start to raise rotation of the direct injection engine at a start of the direct injection engine by fuel injection and multiple sparking performed for a predetermined cylinder in an expansion stroke out of multiple cylinders of the direct injection engine, the start control device of a vehicular direct injection engine reduces the number of times of sparking for the predetermined cylinder at the time of an ignition start of the direct injection engine as compared to an ignition start performed before the current ignition start based on ignition timing of the ignition start performed before the current ignition start.
Claims6
A start control device of a vehicular direct injection engine provided in a vehicle, the start control device comprising:
- an electronic control unit configured to execute an ignition start to raise rotation of the direct injection engine at a start of the direct injection engine by fuel injection and multiple sparking performed for a predetermined cylinder in an expansion stroke out of multiple cylinders of the direct injection engine,
- wherein the electronic control unit reduces a number of times of sparking for the predetermined cylinder at a time of a current ignition start of the direct injection engine as compared to a prior ignition start performed before the current ignition start based on ignition timing of the prior ignition start performed before the current ignition start.
