Your Engine’s Lead Player: The Camshaft | Meineke Lancaster

Understanding Your Vehicle’s Camshaft: Function and Maintenance

Lancaster County’s very own native Jonathan Groff has won a Tony Award for his performance in “Merrily We Roll Along.” And just as he is the lead in this Broadway performance, so too is the camshaft the lead in your engine’s performance. But, for many this part is a mystery. And yet, just like Jonathan Groff, this critical performer should be know by all. Because understanding what the camshaft does and how to maintain it can help you keep your engine running smoothly and efficiently. So, in this blog, the experts at Meineke in Lancaster dive into the purpose of the camshaft, how it works, and provide tips on maintaining it for optimal performance.

What is a Camshaft?

The camshaft is a rotating cylindrical shaft located within the engine. And it plays a pivotal role in the engine’s valve timing by controlling the opening and closing of the intake and exhaust valves. Furthermore, the camshaft is driven by the crankshaft (it’s supporting actor) via a timing belt, chain, or gears. And this ensures that the valves open and close in sync with the movement of the pistons.

How Does the Camshaft Work?

The camshaft features lobes (also known as cams) which are specifically shaped protrusions along its length. And as the camshaft rotates, these lobes push against the valve lifters (or tappets), causing the valves to open. Then, once the lobe passes, the valve spring forces the valve to close. And this precise timing of valve operation is what is the crucial “play” for optimal engine performance. Because it ensures that the right amount of air and fuel mixture enters the combustion chamber and exhaust gases are expelled efficiently.

Types of Camshafts

There are mainly two types of camshafts used in internal combustion engines:

  1. Single Overhead Camshaft (SOHC):

    • Features one camshaft per cylinder bank.
    • Generally used in simpler engine designs.
    • Operates both intake and exhaust valves.

  2. Double Overhead Camshaft (DOHC):

    • Features two camshafts per cylinder bank (one for intake valves and one for exhaust valves).
    • Allows for better air flow and higher performance.
    • Commonly found in high-performance and modern engines.

Importance of the Camshaft

The camshaft’s role in valve timing directly impacts engine performance, fuel efficiency, and emissions. And a well-functioning camshaft ensures that the engine runs smoothly, producing the power needed for various driving conditions. Whereas, malfunctions or wear in the camshaft can lead to poor engine performance, reduced fuel economy, and increased emissions.

Maintaining Your Camshaft

Maintaining your camshaft is key to your engines performance and long, healthy lifespan. So, Meineke in Lancaster recommend this top tips to keep your camshaft in top condition:

  1. Regular Oil Changes:

    • Engine oil lubricates the camshaft and its components, reducing friction and wear. So, regular oil changes are important to ensure that the camshaft and other engine parts are properly lubricated.

  2. Use Quality Oil and Filters:

    • Always use high-quality oil and filters recommended by your vehicle’s manufacturer. This ensures optimal lubrication and filtration, preventing contaminants from damaging the camshaft.

  3. Inspect the Timing Belt/Chain:

    • The timing belt or chain connects the camshaft to the crankshaft. So, regularly inspect it for signs of wear or damage and replace it according to your vehicle’s maintenance schedule. Because, a broken timing belt or chain can cause severe engine damage.

  4. Monitor Engine Performance:

    • Pay attention to any changes in engine performance, such as rough idling, misfires, or decreased power. Because, these could be signs of camshaft issues that need to be addressed by the ASE certified experts at Meineke in Lancaster.

  5. Keep an Eye on the Valve Train:

    • Regularly inspect the valve train components, such as lifters, pushrods, and rocker arms, for wear and proper adjustment. Because, proper valve train operation is essential for the camshaft to function correctly.
  6. Follow the Manufacturer’s Maintenance Schedule:
    • Adhering to the recommended maintenance schedule for your car or truck ensures that all engine components, including the camshaft, are checked and maintained regularly. And Meineke in Lancaster can help you put together a maintenance schedule that fits your lifestyle and your wallet.
