What is the shape of the lower pintle end in a throttling pintle type?

Answer» Correct choice is (B) Truncated cone Explanation: The PINTLE type nozzle carries an extension, which produces a hollow cone-type spray. The pintle is much longer and is ALSO shaped like a truncated cone at its lower end. Such SHAPE causes only a small amount of the fuel to be injected at the ignition start.
