Systems and methods for operating an engine with deactivating and non-deactivating valves are presented. In one example, fuel supplied to cylinders being reactivated is supplied by direct fuel injectors even though the engine is operating in a region (e.g., speed and torque) where under conditions where cylinders are not being reactivated the engine injects fuel solely via port fuel injectors.

An evaporative emissions (EVAP) control system for a vehicle includes a purge pump configured to pump fuel vapor to an engine of the vehicle via a vapor line and a purge valve. The system includes a hydrocarbon (HC) sensor disposed in the vapor line and configured to measure an amount of HC in the fuel vapor pumped by the purge pump to the engine via the vapor line. A controller is configured to: detect an imminent cold start of the engine and, in response to the detecting, perform the cold start of the engine by controlling at least one of the purge pump and the purge valve, based on the measured amount of HC, to deliver a desired amount of fuel vapor to the engine, which decreases HC emissions by the engine.

A control device (7) of a cylinder direct injection type internal combustion engine (1) controls a fuel injection device (4) and an ignition device (5), executes injection of the fuel and ignition over multiple times, and executes a control of varying an interval between a timing of the injection of the fuel and a timing of the ignition, at the time of an ignition start in which the fuel is injected into a combustion chamber (3) in an expansion stroke with rotation of an output shaft (6) is stopped state and the fuel is ignited to start the rotation of the output shaft (6). The control device (7) varies the interval between the timing of the injection of the fuel and the timing of the ignition by adjusting a correlation of a pitch of the injection of the fuel over multiple times and a pitch of the ignition over multiple times. Therefore, the internal combustion engine (1) and the control device (7) have an effect of being able to enhance the starting property.
