| 1. | The gases pass into the exhaust manifold .
这些废气进入排气歧管。 |
| 2. | The exhaust gas exits through the other exhaust manifold .
废气经另外一个排气歧管排出。 |
| 3. | When there is vacuum in the intake manifold, the vacuum holds the diaphragm up .
当进气歧管有真空存在时，真空便向上吸引膜片。 |
| 4. | In the round piston vv carburetor, the piston is moved by intake-manifold vacuum .
在圆形活塞的VV化油器中，活塞是由进气歧管真空移动的。 |
| 5. | If the engine backfires, the sudden pressure in the intake manifold forces the valve back .
如果发动机回火，进气歧管骤增的压力就迫使阀门向后移动。 |
| 6. | This vacuum, called intake-manifold vacuum, varies as the operating conditions change .
这个真空叫做进气歧管真空。这种进气歧管真空随运转情况而变化。 |
| 7. | When the engine is shut off, the intake manifold cools and a slight vacuum forms as a result .
这是因为当发动机熄火时，进气歧管冷却而产生轻微的真空。 |
| 8. | This device, called the manifold heat-control valve, is built into the exhaust and intake manifold .
这种装置称为“歧管热控制阀”，它拼装在排气与进气歧管中。 |
| 9. | The piston moves up and down in the piston chamber primarily in response to changes in intake manifold vacuum .
活塞主要因进气歧管真空度的变化而在活塞腔内上下移动。 |
| 10. | The pudding results from the failure of all the fuel to vaporize and from the sorting effect of the intake manifold .
积洼是全部燃料蒸发得不充分和进气歧管类似影响的结果。 |
