What cars have a non interference engine

## What is a Non-Interference Engine?

In an internal combustion engine, the valves open and close to allow air and fuel into the cylinders, and to allow exhaust gases to escape. The timing of the valve openings and closings is critical to the engine’s performance and efficiency. If the valves are not timed correctly, the engine can be damaged.

In a non-interference engine, the pistons and valves are designed so that they cannot collide with each other, even if the timing belt or chain breaks. This is in contrast to an interference engine, in which the pistons and valves can collide if the timing belt or chain breaks, causing serious engine damage.

## Advantages of Non-Interference Engines

There are several advantages to having a non-interference engine, including:

* **Reduced risk of engine damage.** If the timing belt or chain breaks in a non-interference engine, the engine will not be damaged. This can save you a lot of money in repair costs.
* **Peace of mind.** Knowing that your engine is not at risk of damage if the timing belt or chain breaks can give you peace of mind.
* **Lower maintenance costs.** Non-interference engines typically require less maintenance than interference engines, because the timing belt or chain does not need to be replaced as often.

## Disadvantages of Non-Interference Engines

There are also some disadvantages to having a non-interference engine, including:

* **Lower performance.** Non-interference engines typically have lower performance than interference engines, because the valves cannot be timed as aggressively.
* **Higher emissions.** Non-interference engines typically produce more emissions than interference engines, because the valves cannot be timed as precisely.

## Which Cars Have Non-Interference Engines?

There are many different cars that have non-interference engines. Some of the most popular include:

* **Honda Civic**
* **Toyota Corolla**
* **Mazda3**
* **Volkswagen Golf**
* **Hyundai Elantra**
* **Kia Forte**
* **Nissan Sentra**
* **Chevrolet Cruze**
* **Ford Focus**
* **Subaru Impreza**

If you are looking for a car with a non-interference engine, be sure to check the owner’s manual or consult with a mechanic to verify.

## Conclusion

Non-interference engines offer a number of advantages over interference engines, including reduced risk of engine damage, peace of mind, and lower maintenance costs. However, they also have some disadvantages, such as lower performance and higher emissions. Ultimately, the best type of engine for you will depend on your individual needs and preferences.
