초록 ▼

A method for controlling at least valve to operate in at least a cylinder of an internal combustion engine coupled to a manifold, the method comprising of deactivating said valve in response to an operating condition of a vehicle electrical system, wherein during at least a first condition of the vehicle electrical system said valve is deactivated in a first position that allows at least some airflow between the cylinder and the manifold.

대표청구항 ▼

The invention claimed is: 1. A method for controlling at least a valve to operate in at least a cylinder of an internal combustion engine coupled to a manifold, the method comprising: deactivating said valve in response to an electrical operating condition of a vehicle electrical system, wherein in response to a first electrical condition of the vehicle electrical system said valve is deactivated in a first position that allows at least some airflow between the cylinder and the manifold. 2. The method of claim 1, wherein the valve is an electromechanically actuated valve. 3. The method of claim 1, wherein the valve is a mechanically actuated valve. 4. The method of claim 1 further comprising, deactivating said valve in a second position in response to a second electrical condition of the electrical system, wherein the second position allows less airflow between the cylinder and the manifold than said first position. 5. The method of claim 4, wherein said second position is a closed position of said valve. 6. The method of claim 5, wherein said first electrical condition is a first amount of electrical power available to an engine starter by the vehicle electrical system, said second electrical condition is a second amount of electrical power available to the engine starter by the vehicle electrical system, and said first amount of electrical power is different than the second amount of electrical power. 7. A method for controlling at least a valve to operate in at least a cylinder of an internal combustion engine of a vehicle, the vehicle including an electrical system, the method comprising: operating the valve for a first cycle of the cylinder in response to a first electrical operating condition of the vehicle electrical system; and deactivating operation of said valve for a second cycle of said cylinder in response to a second electrical operating condition of the vehicle electrical system, said valve deactivated in a desired position; wherein said second electrical condition of said electrical system is a lower amount of electrical power available for an engine start from said electrical system compared to an amount of electrical power available in said first electrical condition. 8. The method of claim 7, wherein said desired position is an open position. 9. The method of claim 7, wherein said desired position is a closed position. 10. The method of claim 7, wherein said valve is an electromechanically actuated valve. 11. The method of claim 7, wherein said valve is a mechanically actuated valve. 12. A method for controlling at least a valve to operate in at least a cylinder of an internal combustion engine of a vehicle, the vehicle including an electrical system, the method comprising: starting the engine in a first mode using a first number of valves in response to a first electrical condition of the vehicle electrical system; and starting said engine in a second mode using a second number of valves, said second number of valves less than said first number, in response to a second electrical condition of said vehicle electrical system; said second electrical condition including a lower amount of electrical power available to the engine from the electrical system than said first electrical condition. 13. The method of claim 12, wherein during said second mode at least one valve is deactivated in a closed position. 14. The method of claim 12, wherein during said second mode at least one valve is deactivated in an open position. 15. The method of claim 12 further comprising, deactivating the cylinder wherein at least one valve of said first number of valves is located. 16. The method of claim 12 further comprising, deactivating ancillary vehicle electrical loads during at least one of the first mode and the second mode. 17. The method of claim 12 further comprising, reactivating said valve in response to a third electrical operating condition of said vehicle electrical system. 18. The method of claim 17 further comprising, reactivating one or more mechanically actuated valves in order of a combustion sequence, in response to said third electrical operating condition of said vehicle electrical system. 19. The method of claim 1 wherein the electrical operating condition of the vehicle electrical system is an amount of stored energy of a battery of the vehicle, and the deactivating occurs during engine cranking of an engine start. 20. The method of claim 1 wherein the electrical operating condition of the vehicle electrical system is an available amount of electrical power. 21. The method of claim 19 wherein the deactivated valve is held in the first position for a cycle of the cylinder.
