An automobile includes an engine and an engine controller. The engine includes multiple cylinders. Each cylinder has a fuel injector connected to the engine controller. The engine controller has a first output which activates a first fraction of the fuel injectors. In addition, the engine controller has a second output which activates a second fraction of the fuel injectors. The engine controller also has an input which provides a timing signal synchronous with rotation of the engine and a sequencing circuit responsive to the timing signal. The sequencing circuit periodically alternates between the first and second output in synchronization with the rotation of the engine.

[ What is claimed is:] [1.] A method of selectively activating fuel injectors in an engine having multiple cylinders and an electronic circuit for sensing a state of an input, comprising:operating said engine in a non-split engine mode in response to said electronic circuit sensing a first state of said input;operating said engine in a half-power split engine mode in response to said electronic circuit sensing a second state of said input by sequentially activating a first half of said fuel injectors during a first time period, and activating a second half of said fuel injectors during a second time period; andoperating said engine in a three-quarters power split engine mode in response to said electronic circuit sensing a third state of said input by sequentially activating a first subset of said fuel injectors during a third time period, activating all of said injectors during a fourth time period, and activating a second subset of said fuel injectors during a fifth time period.
