Question 384Motor Plants - Assistant Engineer70% to pass
Large, two-stroke cycle, main propulsion, diesel engine cylinders can be successfully pressure charged during normal operation, by using the _______________.
AI Explanation
The correct answer is C) constant or pulse pressure system.
Large, two-stroke cycle, main propulsion diesel engines can be successfully pressure charged during normal operation by using a constant or pulse pressure system. This system utilizes the exhaust gas energy to drive a turbocharger, which then compresses the intake air, increasing the air density and enabling more efficient combustion in the engine cylinders.
The other options are incorrect because: A) the exhaust gas temperature system is not used for pressure charging, B) the exhaust load system is not a common method for pressure charging, and D) the constant volume system is not applicable for pressure charging in this type of diesel engine.
