In an engine, the piston's go up and the valve's that are adjacent to that piston go up. When the piston goes down the adjacent valves go down. This is achieved by the timing belt or chain and the engine timing being set correctly.
If the belt or chain breaks, the pistons still go up and down, but the valve's stop moving. On a non clearance engine, the piston will go up and hit the valves, resulting in bent valves and a now needed head job.
In a clearance engine, the top of the piston has an inset cut into it that is just enough room to avoid hitting the valves.
The 1991 Toyota Corolla does not have a zero-clearance engine. It has a non-interference engine. This means that the pistons will not travel to the pistons.
Yes...Well it is an interference engine, not zero clearance. Which means when the timing belt breaks the pistons with "interfere" with the valves.
no
Yes, it is an interference engine.Yes, it is an interference engine.
According to Gates ( they manufacture timing belts etc. ) No , it is not an interference engine
The Chevy Aveo 1.6L engine is not classified as a zero clearance engine. Zero clearance engines, also known as interference engines, are designed in such a way that if the timing belt or chain fails, the pistons and valves can collide, leading to significant engine damage. The Aveo's design allows for some clearance between the pistons and valves, reducing the risk of severe damage in the event of a timing failure. However, it's always best to maintain the timing components to prevent any potential issues.
yes this is a zero clearance engine design
I believe it is not a zero clearance engine because it doesn't have a defined mileage for the timing belt change.
The 3.4 Liter V6 is an interference engine and as such if the belt breaks you will have serious engine damage. The 4 cylinder uses a cam chain that will last the life of the engine.
I assume you mean zero interference. If so then 2006 Honda Civic's and up are non-interference. 2005 and older are interference engine.
This is an interference engine. In most cases the head as well and the pistons will be damaged.
Yes.
