Question

The construction of a two stroke cycle engine is ____________ because it has ports instead of valves.

(a) complex

(b) simple

(c) unpredictable

(d) none of the mentioned

I got this question during an internship interview.

My doubt stems from Advantages of Two Stroke Engines in chapter Two Stroke Engines of IC Engine

Answer 1

The correct answer is:

(b) simple

The construction of a two-stroke cycle engine is simple because it uses ports instead of valves. This design eliminates the need for a complex valve mechanism, making the engine lighter, more compact, and easier to manufacture. Since two-stroke engines rely on ports for the intake and exhaust processes, they have fewer moving parts compared to four-stroke engines, which use valves, camshafts, and other components.
