The camshaft is a metal shaft in the engine responsible for controlling the timing and movement of the intake and exhaust valves. These valves

regulate airflow in and out of the combustion chamber. As the camshaft rotates, it uses specially shaped lobes to open and close the valves

at precise intervals, in sync with the piston movement.

Every model in the Changan lineup, including the performance-oriented Changan Deepal S07, relies on this component to achieve

optimal power and fuel efficiency.

What Does the Camshaft Do?

The camshaft performs two key functions:

  • Opens intake valves to allow a mixture of air and fuel into the engine.

  • Opens exhaust valves to let out burnt gases after combustion.

The shape and timing of the camshaft lobes determine how long and how far the valves open, directly affecting engine performance, fuel economy,

and emissions — core values in every Changan vehicle design.

Camshaft vs. Crankshaft: What’s the Difference?

Though both are vital to the engine, their roles are quite distinct:

 

Feature Camshaft Crankshaft
Primary Role Controls valve timing Converts piston motion into power
Position Typically in the cylinder head Located in the bottom engine block
Connected To Valvetrain Pistons and flywheel
Speed Rotates at half the crankshaft speed Rotates with every piston stroke

In short, the camshaft helps the engine breathe, while the crankshaft turns that motion into usable energy.

Camshaft Sensors in Modern Changan Models

Advanced Changan vehicles, such as the Deepal S07, use a camshaft position sensor. This sensor communicates with the vehicle’s ECU (engine

control unit) to fine-tune fuel injection and ignition timing. If this sensor fails, your engine may misfire, run inefficiently, or display a check engine

light.

Camshaft Bearings and Maintenance

The camshaft spins inside bearings that minimize friction and prevent premature wear. To ensure longevity:

  • Regular oil changes are essential.

  • Avoid using low-grade or dirty engine oil.

  • Pay attention to signs of unusual engine noise or misfiring.

 

If you’re noticing issues, it might not just be the camshaft — it could be a power issue. Consider checking your vehicle’s battery and explore

new battery options tailored for Changan models.

Signs of a Worn or Damaged Camshaft

Watch for these symptoms that may suggest a camshaft issue:

  • Engine misfires or hesitation

  • Clicking or tapping noises from the engine

  • Rough idling or poor fuel economy

  • Difficulty starting the vehicle

  • A persistent check engine light

These signs can often be misdiagnosed, so it’s best to schedule a proper diagnostic with a Changan-certified service center.

Frequently Asked Questions About the Camshaft

What does a camshaft do in an engine?

It controls when the engine valves open and close, helping manage airflow for combustion.

Is a camshaft the same as a crankshaft?

No — the camshaft handles valve timing, while the crankshaft transforms linear motion into rotation.

Where is the camshaft located?

In most modern Changan engines, it’s found in the cylinder head (overhead camshaft design).

What causes camshaft failure?

Most issues arise from poor lubrication, bearing wear, or timing belt/chain problems.

Can I drive with a faulty camshaft?

It’s not recommended. Continuing to drive can cause further engine damage or failure.

Can a camshaft be repaired?

In some cases, yes. But in severe cases, a replacement may be necessary for safe and efficient performance.

 

Final Thoughts

The camshaft may be hidden beneath your vehicle’s sleek exterior, but its role is foundational to engine health. Whether you’re interested in the

reliable Karvaan MPV Plus, the luxury and comfort of the Oshan X7, or a tech-forward EV like the Deepal S07, keeping your camshaft in good

condition is key to long-term driving satisfaction.
