Abstract

A control apparatus for an internal combustion engine that can be a four-cycle engine including cylinders into which fuel is directly injected, the control apparatus includes an electronic control unit. The electronic control unit is configured to execute a fuel injection and an ignition for the cylinder in an expansion stroke on a condition that a stop of the piston in any one of the cylinders at vicinity of a top dead center after a compression stroke is predicted when the electronic control unit is configured to stop the fuel injection and the ignition for the internal combustion engine upon fulfillment of a predetermined stop condition.

First claim

What is claimed is:

1. A vehicle comprising:
an internal combustion engine including
a first cylinder;
a second cylinder;
a piston in the first cylinder;
a crankshaft;
a fuel injector corresponding to the second cylinder; and
an igniter corresponding to the second cylinder; and

an electronic control unit configured to
predict, based on a rotational speed and an angle of the crankshaft, whether the piston is going to stop at a vicinity of a top dead center when a fu…
