Product type
A DOHC camshaft, or Dual Overhead Camshaft, is a critical component in an internal combustion engine that controls the opening and closing of the engine's intake and exhaust valves. Typically made from high-strength steel or aluminum alloys, these camshafts are designed to optimize engine performance by allowing for precise timing and greater airflow. This design is commonly used in high-performance and modern engines to enhance efficiency and power output.
| Material | High-strength steel or aluminum alloys |
| Camshaft type | Dual Overhead |
| Number of valves per cylinder | Typically 4 |
| Lift range | 0.3 to 0.6 inches |
| Duration range | 200 to 300 degrees |
| Compatibility | Various engine models and makes |
When selecting a DOHC camshaft, consider the specific engine model and the desired performance characteristics. Key specifications to specify include the lift and duration of the camshaft, as well as any required tolerances or certifications. Additionally, buyers should assess the intended application, whether for street use or racing, and request quotes for the appropriate quantities based on their project needs.
