Poppet valves are the one whose valve stem moves up and down in a valve guide.

Answer: A

Explanation

Poppet valve is used for controlling the flow of fluid in the engine.

The valves are present inside a cylindrical structure from where the fluids will get inserted or exhausted.

The timing of input and output as well the quantity of input and output is maintained by Poppet valve.

The valve consists of a large metal plate connected with a long metal rod.

The metal rod is termed as valve stem which is present in the valve guide.

The valve stem will be moving up and down to insert and exhaust the gases respectively in an internal combustion engine.

#include<iostream>

using namespace std;

unsigned int second_a(unsigned int n)

{

int r,sum=0,temp;

int first;

for(int i= 1; I<=n; i++)

{

first = n;

//Check if first digit is 3

// Remove last digit from number till only one digit is left

while(first >= 10)

{

first = first / 10;

}

if(first == 3) // if first digit is 3

{

//Check if n is palindrome

temp=n; // save the value of n in a temporary Variable

while(n>0)

{

r=n%10; //getting remainder

sum=(sum*10)+r;

n=n/10;

}

if(temp==sum)

cout<<n<<" is a palindrome";

else

cout<<n<<" is not a palindrome";

}

}

}

Explanation:
