Each firing sequence uses a different firing fraction.

The initialization sequence initiated by the invention can be identical to the power-on sequence, or it can be a separate, reinitiating sequence.

An ECU receives the torque and engine speed signals and sets the ignition timing in accordance with the ignition tables to produce torque levels below the maximum capacity of the engine.

This inflator can inflate an airbag at different rates dependent on the firing sequence used.

Based on the knocking determination result, ignition timing of the engine is controlled.

In some embodiments, transitions are constrained to occur when firing sequence segments of a designated length are shared by the first and second firing fractions.

In another aspect of the invention, a determination is made as to whether a firing sequence should be dynamically generated or selected from a set of predefined firing sequences.

In one aspect of the invention, a distinct firing sequence is determined for each bank of working chambers that is used to operate the bank in a skip fire manner.

A hot-air delivery system which can replace gasoline and spark plugs with heated pneumatic energy, which is delivered to the engine through pneumatic injector plugs, in accordance to engine firing order.
