What is the benefit of an interference engine?
But as manufacturers design smaller engines that in turn need to produce more power, interference engines have been shown to breathe better and have a higher compression ratio to aid performance. Specifically, they come with larger valves that open further into the combustion chamber.
Is an interference engine bad?
Consequently, by design, interference engines are susceptible to; critical failure in the event of a timing belt failure. So, if the timing belt snaps, the pistons will smash into the valves; causing serious (and costly) engine damage. Therefore, there’s little risk of catastrophic engine damage.
What is the difference between interference motor and non-interference motor?
Interference engines are 4-stroke engines that open one or more valves to fully accommodate the area in which the pistons enter. In comparison, non-interference engines feature pistons that do not travel into the open valves.
Why do manufacturers make interference engines?
Most modern cars have interference engines. The reason is that manufacturers strive to make the engines more efficient by increasing the compression ratio and make the valves open wider for more air flow. The compression ratio is increased by reducing the volume of the combustion chambers.
Are Mercedes interference engines?
most mercedes engines now a days are interference engines.
What happens if a timing belt breaks on an interference engine?
If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position. This may result in a heavy damage to the engine with broken or bent valves, damaged pistons and, possibly, destroyed cylinder head and block.
What makes an engine an interference engine?
An interference engine is a type of 4-stroke internal combustion piston engine in which one or more valves in the fully open position extends into any area through which the piston may travel. By contrast, in a non-interference engine, the piston does not travel into any area into which the valves open.
What cars have interference engines?
All Honda cars from 1984 through 1996 have interference engines. The engine codes include ES2, ES3, A18A1, A20A1 and A20A3 in the 1984 through 1989 Accord and Prelude.
What does interference mean in an engine?
An interference engine is a type of 4-stroke internal combustion piston engine in which one or more valves in the fully open position extends into any area that the piston may travel into.
What engines are non interference?
