Definition

Noun: A component of an internal combustion engine that collects exhaust gases from multiple engine cylinders and channels them into a single exhaust pipe or turbocharger inlet.

Usage

The term "exhaust manifold" is used specifically in the context of automotive and mechanical engineering. It refers to a crucial part of a vehicle's exhaust system.

Examples

• The mechanic replaced the cracked exhaust manifold.
• High-performance engines often use tubular steel exhaust manifolds for better gas flow.
• A leak in the exhaust manifold can be dangerous and reduce engine efficiency.

Advanced Usage

• Performance Exhaust Manifold: A specially designed manifold, often with equal-length tubing, to improve engine power by optimizing exhaust gas scavenging.
• Exhaust Manifold Gasket: The seal placed between the manifold and the engine cylinder head to prevent leaks.

Variants and Related Words

• Intake Manifold (n): The component that distributes air or air-fuel mixture to the cylinders. It is the counterpart to the exhaust manifold.
• Header (n): A type of performance exhaust manifold, typically with individual tubes for each cylinder.
• Manifold (n): A pipe or chamber with multiple inlets or outlets, for connecting different parts of a system.

Synonyms

• Exhaust header (specifically for performance tubular designs)

Related Phrases

• To bolt on an exhaust manifold: To install or attach the manifold to the engine.
• Exhaust manifold heat shield: A protective cover that prevents excessive heat from the manifold from damaging nearby components.

Noun

1. a manifold that receives exhaust gases from the cylinders and conducts them to the exhaust pipe
