摘要:
A hybrid vehicle includes an electric motor, an internal combustion engine, an exhaust emission control device and a controller. The controller is configured to execute catalyst warm-up control for warming up a catalyst of the exhaust emission control device. The catalyst warm-up control includes first control and second control. The first control is control for operating the internal combustion engine at a first operating point. The second control is control for, after the first control is executed, operating the internal combustion engine at a second operating point irrespective of a driving force that is required to propel the hybrid vehicle. An output of the internal combustion engine at the second operating point is larger than an output of the internal combustion engine at the first operating point. The controller is configured to operate the internal combustion engine while an ignition timing of the internal combustion engine at the time when the first control is executed is set to a retarded side with respect to an ignition timing of the internal combustion engine at the time when the second control is executed. The controller is configured to, when the first control is executed, control the variable valve actuating device such that the operation characteristic becomes the first characteristic. The controller is configured to, when the second control is executed, control the variable valve actuating device such that the operation characteristic is changed to the second characteristic. The controller is configured to, after the second control is executed, operate the internal combustion engine on the basis of the driving force that is required to propel the hybrid vehicle and control the variable valve actuating device on the basis of a rotation speed and torque of the internal combustion engine.

A hybrid vehicle includes an internal combustion engine, an electrical storage device, a rotary electric machine, and a controller. The internal combustion engine includes a variable valve actuating device. The variable valve actuating device is configured to change an operation characteristic of an intake valve. The electrical storage device is configured to be charged. The rotary electric machine is configured to generate driving force for propelling the hybrid vehicle by using electric power that is supplied from the electrical storage device. The controller is configured to cause the hybrid vehicle to travel in a selected one of a charge sustaining mode and a charge depleting mode. The charge sustaining mode is a mode in which a state of charge of the electrical storage device is kept within a predetermined range. The charge depleting mode is a mode in which consumption of the state of charge is given a higher priority as compared to the charge sustaining mode. The controller is configured to change a switching condition for switching from the charge depleting mode to the charge sustaining mode such that a first state of charge is higher than a second state of charge. The first state of charge is an state of charge at which the controller switches from the charge depleting mode to the charge sustaining mode at the time when the operation characteristic of the intake valve is unchangeable to a desired operation characteristic. The second state of charge is an state of charge at which the controller switches from the charge depleting mode to the charge sustaining mode at the time when the operation characteristic of the intake valve is changeable to a desired operation characteristic.
摘要:
An ignition and combustion control method for controlling ignition and combustion within an HCCI engine includes varying a fuel composition of a reformed fuel product for fueling the HCCI engine in response to changing loads or speeds of the HCCI engine. The fuel composition is varied by varying a water/fuel ratio of a mixture of water and fuel that is introduced into a fuel reformer to produce the reformed fuel product, and by controlling a temperature of a reaction within the fuel reformer. The HCCI engine is fueled with the fuel product.
