Where is the EGR valve on a 1997 Hyundai Elantra?
Does not have one. The engine uses cam overlap to achieve the effect of the EGR valve.
What does the term valve overlap mean?
Valve timing overlap is the time when both exhaust and intake valves are open most engines with catalytic converters require valve overlap in order to send a small amount of raw fuel/ air mix to the converter's. An "open cam" has valve overlap a "closed" cam does not
What is the purpose of the valve in an engine?
The purpose of the valve spring is to maintain contact between the components in the valve train, so the valve motion will follow the cam profile.

What is valve overlap?
Valve overlap occurs in a four-stroke engine at the end of the Exhaust stroke and at the beginning of the Induction stroke; and is when both the exhaust and inlet valves are open at the same time. At the end of the Exhaust stroke, the Exhaust valve is closing and the Inlet valve is starting to open in preparation for the induction of fuel and air into the cylinder. It is common knowledge that in vehicles that cannot alter the valve timing, the Inlet valve opens approx 6 degrees before top-dead-centre and the Exhaust valve closes at 9 degrees after top-dead-centre
When the intake and exhaust valves are both open at the same time that length of time is called?
Valve overlap.
What is the purpose of a valve tappet?
To move the valve down as the camshaft rotates.
What is the purpose of valve ports?
The purpose of Valve Ports is to let exhaust gases out of the cylinder and to let air and fuel mixture into the cylinder!
What does a overlap valve do?
send a small amount of raw fuel/air to the catalytic convertor,which increases the efficiency of the operating engine.
What is the purpose of geyser pressure valve?
The purpose of a pressure relief valve in a geyser is to release the pressure created inside due to evaporation of water.
What is the purpose of the PVC valve?
A PVC Valve shuts off water A pcv valve is for positive crankcase ventilation in an engine
What are the disadvantages to have a large valve overlap?
High end Rpm output tails sooner, engines idle is lumpy, emissions are higher, too much overlap can cause rough low rpm driving, more chance of detonation.
