How many valves does a Subaru have?
Subaru engines typically have four valves per cylinder, which is a common configuration for modern automotive engines. This means that a typical Subaru engine will have a total number of valves that is a multiple of four, depending on the number of cylinders in the engine.
Subaru Engine Valve Configurations
Subaru is known for its use of horizontally-opposed "boxer" engines, which have a unique valve train design compared to more common inline or V-shaped engines. The key features of Subaru's valve train include:
- Four valves per cylinder (two intake, two exhaust)
- Overhead camshaft design, with one camshaft per cylinder bank
- Timing chain or timing belt to synchronize the camshafts with the crankshaft
The total number of valves in a Subaru engine depends on the number of cylinders. Common Subaru engine configurations include:
- 4-cylinder engines: 16 valves total (4 cylinders x 4 valves per cylinder)
- 6-cylinder engines: 24 valves total (6 cylinders x 4 valves per cylinder)
So in summary, a typical Subaru engine will have either 16 or 24 valves, depending on whether it is a 4-cylinder or 6-cylinder engine. This four-valves-per-cylinder design helps Subaru engines achieve good power output, efficiency, and emissions performance.
