Hello Adarsh, if your question is that whether BTech in Delhi Technological University(DTU) has a seperate entrance exam, the answer is a no. For any student to apply for the course they need to pass their class 12 examinations on or before 2018 with atleast 50% aggregate marks in Physics,Chemistry and Maths (where you have to pass each subject seperately and also pass in English as a core subject). The admissions will be based on JEE mains rank and marks, where you have to secure a minimum of 60% marks. Once that is done, you can apply for Btech in DTU.

All the best to you! :D
