Timing belt

Recommended Posts

There are two types of engines that use timing belts.  They are

described as: "Interference Engines" and "Non-interference Engines"  The

difference lies in the proximity between the valves and the pistons.  On an

interference engine, if the timing belt slips even one notch, the piston can

crash into an open valve causing serious engine damage by bending valves and

breaking pistons.  Non-interference engines will usually not self destruct,

but in either case if the belt fails, the engine will immediately shut down leaving you

stranded.

If I may add:

Delaying a timing belt change (for a few rupees) is probably the biggest mistake up you can make. If you have an 'interference engine' (as most are nowadays) your valves will be good for use only as harpoons, or large nails. The piston(s), cylinder walls, are all at severe risk. In the case of rubber belts (as many are) you will not have any advance warning. Even with chain type belts you are unlikely to to get this since the tensioner will not allow any rattle noises to start.

Yes' date=' but chain type belts are not used due to high noise levels. Or are they in some cars?

I also thought so. You will be surprised at the number. I cannot list these offhand but these are plentiful. .

Older engines employed the chain type timing belts. Now a days they are really belt like' date=' like the fan belts.

Many modern engines do use a chain timing belt.

Rubber Timing belts have to be 'cogged' and not Vee or Grooved!
