EVAPORATIVE SYSTEM |
| 摘要 |
An evaporative system is for an internal combustion engine. The internal combustion engine has an intake pipe equipped with a supercharger to pressurize intake air. The evaporative system includes an ejector, an ejector passage, and a pressure sensor. The ejector is to draw intake airflow from a downstream of the supercharger to an upstream of the supercharger to cause a negative pressure to draw fuel vapor into the upstream of the supercharger. The ejector passage is branched from the downstream of the supercharger and is returned through the ejector to the upstream of the supercharger. The pressure sensor is communicated with the ejector passage to detect pressure in the ejector passage. |

1. An evaporative system for an internal combustion engine, the internal combustion engine having an intake pipe equipped with a supercharger to pressurize intake air, the evaporative system comprising:
an ejector configured to draw intake airflow from a downstream of the supercharger to an upstream of the supercharger to cause a negative pressure to draw fuel vapor into the upstream of the supercharger; an ejector passage branched from the downstream of the supercharger and returned through the ejector to the upstream of the supercharger; and a pressure sensor communicated with the ejector passage and configured to detect pressure in the ejector passage. |
