Two technicians are discussing variable valve timing technician a says that changing the exhaust valve timing how to reduce exhaust emissions says it change in the intake valve timing helped increase low speed torque

Both technicians A and B are correct.

Explanation:

Variable valve timing is the process of changing the time of a valve lift in the internal combustion engine. This process is usually used to enhance the performance,emissions or the efficient consumption of fuel.

Now a days, variable valve timing is commonly used with a combination of variable valve lift systems in internal combustion engines.

Therefore,  technician A(changing the exhaust valve timing how to reduce exhaust emissions) and technician B (it changes in the intake valve timing helped increase low speed torque) are correct.

this is true
