Help to ID Tree with thorns and fruit

Does anyone know what the name is or the fruit is on the attached pictures?
The tree is covered with thorns ranging from an inch in length to 3 inches in length.
It is also full of the green fruit shown. I have been unable to identify it for certain. Thanks.

 

Looks like Poncirus trifoliata, Trifoliate Orange.

 

After you sent me the name, I searched the internet and am sure you have identified it. Thank you very much.
