Wastegate

定义 Definition

wastegate(名词):(涡轮增压器的)废气旁通阀/泄压阀。用于调节进入涡轮的废气流量,防止增压压力(boost)过高,从而保护发动机与涡轮系统、稳定输出。(在汽车与发动机工程语境中最常见)

发音 Pronunciation (IPA)

/westet/

例句 Examples

The wastegate opens to prevent overboost.
废气旁通阀打开以防止增压过高。

When the ECU detects excessive boost pressure, it commands the wastegate actuator to divert exhaust flow and stabilize the turbo’s speed.
当ECU检测到增压压力过高时,会控制废气旁通阀执行器分流废气,以稳定涡轮转速。

词源 Etymology

waste(“废弃/多余的”)+ gate(“闸门/阀门”)构成,字面意思是“把多余的(废气能量)放走的阀门”。在涡轮系统中,它不是“浪费”,而是通过“旁通”来精确控制增压压力与涡轮转速。
