DETERMINATION OF A HIGH PRESSURE EXHAUST SPRING IN A CYLINDER OF AN INTERNAL COMBUSTION ENGINE |
| 摘要 |
A variety of methods and arrangements for determining whether a high pressure exhaust spring is present in a cylinder of an internal combustion engine are described. For spark ignition engines, the electrical properties of the spark plug spark gap may be used to determine whether a high pressure exhaust spring is present. |

1. A method of determining whether a high pressure exhaust spring is present in a cylinder of a spark ignition, internal combustion engine having a reciprocating piston, the method comprising:
measuring at least one electrical property of a spark gap in a cylinder; and based on the electrical property measurement, determining whether a high pressure exhaust spring is present in the cylinder. |
