What is Non-Interference Engines?

The latest internal combustion engine is a complex space of moving parts that can cause chaos if not working as desired.

The effect of chaos depends on whether your car is powered by a non-interference engine or an interference engine.

This type of engine will tell if the chaos will cause severe engine damage or minor engine repairs.


The working of an engine is based on the movement of pistons and the crankshaft. The smoother the movement, the better condition of the engine.

In engine terminology, interference refers to the paths that the pistons and valves travel. But the most interesting thing is to notice if those paths cross.

To put it in simple words, in a non-interference engine the piston is situated at the top dead center so that it can never go higher than a fully open valve.

Thus, being placed so high, the piston can never interfere with the valves.

18 List of Cars with Non-Interference Engines

Many top automobile brands offer interference and non-interference engines. Generally, there are many different types of engines, and each of them can be categorized into interference & non-interference engine.

One might find it unnecessary to learn about types of engines as it is a technical matter. But as a driver, it is crucial to know and understand the difference between the two types.

Crucial Parts Of Non-Interference Engine

Now that we have decoded the list of cars with non-interference engines, let us look at the list of the crucial parts of a non-interference engine.

1. Valves

Valves are the parts that are used for starting or stopping the flow, preventing backflow or relieving, regulating or throttling flow, and regulating pressure in fluid or gaseous handling applications.

Engine valves are mechanical parts used in internal combustion engines to enable or restrict the flow of fluid or gas from combustion chambers or cylinders during engine operation.

2. Piston

A slider that is moved or shaken by the pressure of a liquid, usually consisting of a small cylindrical body in a cylindrical chamber or vessel along which it moves back and forth, is called a piston.

In engines, pistons are, among other things, the parts that drive engines, pumps, gas compressors, hydraulic cylinders, and pneumatic cylinders.

Its main task in the engine is to transfer force from the expanding gas in the cylinder to the crankshaft via the piston rod.

3. Timing Belt

The timing belt is a serpentine belt that runs along one side of the engine to properly synchronize the camshaft and crankshaft.

The main purpose of the timing belt is to synchronize the upper half of the motor with the lower half of the motor.

Difference Between Non-Interference & Interference Engine

The main difference between a non-interference and an interference engine is in the way the valves of these engines open.

  • Non-interference engines have pistons that do not get inside or touch the open valves, maintaining a safe distance.
  • Interference engines have four strokes that open one or more valves to entirely fit the space in which the pistons enter.

In simpler terms, in an interference engine, there will be contact between the piston and the valve. However, in a non-interference engine, the piston is placed far down so that they never touch

What Happens If Timing Belt Snaps?

If the timing belt snaps, it can harm the engine of your vehicle based on its type. Thus, you must go through the list of cars with non-interference engines.

  • In an interference engine, the piston & valve’s stroke takes up a similar space in the cylinder. The timing belt is crucial here as it keeps these parts from smashing into each other.

So, if the timing belt somehow snaps, there is a huge chance of valve or cylinder damage to occur, which can harm your engine to severity.

  • In a non-interference engine, the vales & pistons do not take up similar space in the cylinder. So even if the timing belt snaps, there is no cylinder or valve damage. All you need to do is have it replaced, and the engine will be just as its former self.
