19 List Of Cars With Non-Interference Engines With Integral Parts

list of cars with non interference engines

Interference and non interference engines are two popular combustion engine types that are generally powered by petrol. To help you learn more, we bring you a list of cars with non interference engines. 

If you are confused about whether you should go for an interference or non-interference engine, we are here to help.

A timing chain or timing belt is one of the most crucial parts of combustion engines. Generally, when this belt or chain snaps, your engine gets damaged. But in some cases, your engine is saved, and you are made aware of the upcoming severity.

The engine that is somehow immune to the destruction that a snapped timing belt can cause and warns is a non interference engine.

Thus, if you wish to own a car with an engine that gives you time to handle the broken timing belt or chain issue instead of coming to a complete halt, we recommend you explore our non interference engine list.

Exploring cars with non interference engines is quite different from exploring cheap cars with paddle shifters, so go through each detail carefully.

Difference Between Non Interference Engine & Interference Engine

Before we begin exploring modern cars with non interference engines, it is highly crucial that you, as a buyer, should understand the terminology of a non interference engine.

The modern internal combustion engine is a complex space enclosing several moving parts that can break havoc if not working as they should.

However, the damage your car will incur due to the internal parts not functioning properly depends on whether your car is powered by an interference engine or a non interference engine.

This difference in engine will tell if you will have severe engine damage or some minor engine repairs on your hands.

What engines are non interference engines?

If you own cars with non interference engines, then you should know that a non-interference engine is a type of internal combustion engine.

In this type of engine, the piston and valves operate independently without any risk of collision. 

In Layman’s terms, the pistons and valves never occupy the same space within the combustion chamber of the engine, ensuring they never interfere with each other’s movement.

So, even if your timing belt or chain breaks, it will not bring your engine to a halt. You will surely hear rattling sounds as an indication of the issue, giving you enough time to work on the issue and have it fixed.

What is an interference engine?

An interference engine is a 4-stroke type of internal combustion piston engine. In this engine, one or more valves in their fully open position extend into any area through which the piston may travel.

In simpler terms, both pistons and valves occupy the same space within the combustion chamber in an interference engine but at different times.

This engine design maximizes the engine’s compression ratio, leading to increased performance and fuel economy.

However, this is not such a great thing as an interference engine risks major internal damage because if there is a failure of camshaft drive belts, drive gears or drive chains, pistons will strike the valves, damaging the engine entirely.

Interference Engine vs Non Interference Engine

interference vs non interference engine
AspectNon-Interference EngineInterference Engine
Valve-Piston GapThere is a gap between a fully open valve and the piston at the top of its stroke.There is no gap between a fully open valve and the piston at the top of its stroke.
DesignThe piston does not move into any space into which the valves open.One or more valves in the fully open position extends into any space through which the piston may move.
PerformancePerformance may not be as high as interference engines.Offers improved compression ratio, which further provides enhanced performance & fuel efficiency.
Risk in Timing Belt/Chain FailureIf the timing belt or chain breaks, the pistons won’t make contact with the valves. Thus there is only a little risk of catastrophic engine damage.If the timing belt or chain breaks, the pistons will smash into the valves, causing serious and expensive engine damage.
MaintenanceRegular maintenance and timely replacement of the timing belt is crucial, but the risk of engine damage is lower if the timing belt or chain fails.Requires regular maintenance and timely replacement of the timing belt to prevent catastrophic engine damage.

What Are The Integral Parts Of A Non Interference Engine?

Now that you are fully aware a list of cars with non-interference engines roaring the roads, let us have a look at the various crucial parts of a non-interference engine.

Timing Belt

The timing belt or chain is a serpentine belt that is placed on one end or side of the engine of your ride to properly synchronize the crankshaft and camshaft.

The main purpose of a timing chain in any engine is to synchronize the upper half of the engine motor with the lower half of the engine motor.

Valves

Valves are an integral part of an engine. They are mechanical parts used in internal combustion engines to restrict or enable the flow of gas or fluid from combustion cylinders or chambers during engine operation.

Valves are the ones that start or stop the flow, prevent backflow, regulate flow, and regulate pressure in gaseous or fluid handling applications.

Piston

The piston is a slider component in an engine that is moved by the pressure of a liquid. It generally comprses of a small cylindrical body in a cylindrical vessel along which it moves back and forth. Pistons in engines are a crucial component that drives engines and pump gas compressors, pneumatic cylinders, and hydraulic cylinders.

The main task of a piston in an engine is to transfer force from the expanding gas in the cylinder to the crankshaft through the piston rod.

All FAQs About Non-Interference Car Engine List

Is there a list of cars with non interference engines Mercedes?

NO. Mercedes Benz did produce a few non interference engines back in time. However, most of the engines manufactured by the company since 1980 are interference engines. Thus, if you were exclusively looking for a Mercedes non interference engine list, you would be disappointed.

What happens if the timing belt snaps?

The timing belt is the one that ensures the smooth operation of the piston and valves. If it snaps, it can harm your engine, but the severity of the harm depends on the type of your engine.

If you own a non interference engine, there will not be much damage that can’t be repaired. You will be able to tackle the issue before it gets worse.

However, if you own an interference engine, the breaking of the timing belt will result in the piston and valves colliding, resulting in the bending and breaking of several engine parts and ultimately killing your engine.

Thus, to ensure no such thing happens, you need to take good care of your car engine and replace the timing belt as soon as it shows any signs of wear and tear.

Why do interference engines exist?

Interference engines exist simply because they offer several advantages over non interference engines.

With interference engines, you get a high compression ratio, more power, increased efficiency, and reduced emissions.

Bottom line, is that interference is more potent, more environmentally friendly, and offers more power and efficiency.

Advantages of Interference Engines:

  • Increased Power & Efficiency
  • Higher Compression Ratio
  • Reduced Emissions
What car brands have non interference engines?

Over the decades, interference engines have become highly popular mainly because of the advantages they possess over non interference engines.

However, despite this popularity, there are some automakers who either used to or still produce a few non interference engines.

Below, we have a list covering the top car brands (alphabetically) that have non interference engines under their names:

  • Acura
  • Chrysler
  • Ford
