A controller, a vehicle incorporating the controller, and a method for controlling operation of a direct injection internal combustion engine having a combustion chamber for performing a plurality of operating cycles. The controller is configured to receive a fuel cut signal indicative of a request to inhibit fuel injection into the combustion chamber and, in dependence on the fuel cut signal, control a fuel supply system to inhibit fuel injection into the combustion chamber to perform one or more fuel cut operating cycle. The controller determines a particulate loading of a particulate filter in an exhaust system. During the one or more fuel cut operating cycle, the controller is configured to control operation of an intake valve to control the introduction of intake gases into the combustion chamber in dependence on the determined particulate loading of the particulate filter.

Controller and method for controlling operation of a direct injection internal combustion engine

A control system for controlling operation of an internal combustion engine is configured to: receive a first request signal indicative of first torque demand; determine a schedule defining an opening timing of the intake valve and a closing timing of the intake valve of a cylinder of the internal combustion engine in dependence on the first torque demand; and cause the intake valve to open in accordance with the schedule. The control system is also configured to, during a period in which the intake valve is open: receive a second torque request signal indicative of a second torque demand different to the first torque demand; determine an updated schedule defining an updated closing timing of the intake valve in dependence on the second torque demand; and cause the intake valve to close in accordance with the updated schedule.
