Question 143Motor Plants - Assistant Engineer70% to pass
In a two-stroke cycle, opposed-piston, diesel engine, one crankshaft operates several crank angles in advance of the other crankshaft to_______________.
AI Explanation
The correct answer is A) allow the exhaust ports to open and close before the inlet ports close.
In a two-stroke, opposed-piston diesel engine, the two crankshafts are designed to operate at different crank angles to optimize the timing of the engine's intake and exhaust events. By having one crankshaft operate several crank angles in advance of the other, it allows the exhaust ports to open and close before the inlet ports close. This ensures efficient scavenging of the exhaust gases and proper filling of the cylinders with the fresh intake charge, improving the engine's overall performance and efficiency.
The other options are incorrect because they do not accurately describe the purpose of the offset crankshaft design in an opposed-piston, two-stroke diesel engine.
