MULTI-CYLINDER INTERNAL COMBUSTION ENGINE AND METHOD FOR OPERATING A MULTI-CYLINDER INTERNAL COMBUSTION ENGINE |
| 摘要 |
A method for partial cylinder cutoff is provided. The method comprises operating a multi-cylinder internal combustion engine with applied ignition, in which an odd number n of cylinders is arranged in line, and during partial-load operation when engine load is below threshold, enabling a partial cutoff of the cylinders, the partial cutoff comprising operating each cylinder only intermittently such that each cylinder is fired and cut off in turn at an interval of (2*720° CA)/n. |

1. A method, comprising
operating a multi-cylinder direct-fuel-injection internal combustion engine with spark ignition, in which an odd number (n) of cylinders is arranged in line; and during partial-load operation when engine load is below threshold, adjusting engine airflow and enabling a partial cutoff of the cylinders, the partial cutoff comprising operating each cylinder only intermittently such that each cylinder is fired and cut off in turn at an interval of (2*720° CA)/n. |
