1. High speed two stroke engines are ____________ efficient owing to the reduced volumetric efficiency.

2. A two stroke cycle engine gives _____________ the number of power strokes as compared to the four stroke cycle engine, at the same engine speed.

3. The thermal efficiency of a petrol engine is ____________ as compared to diesel engine.

4. Inadequate scavenging leads to a low amount of oxygen availability which results in incomplete combustion leading to higher specific fuel combustion.

5. As there is a working stroke in every revolution, a more uniform turning moment is obtained on the crankshaft and therefore, a __________ flywheel is required.

6. In compression ignition engines, swirl denotes a __________

7. The colour of exhaust from diesel engine is generally __________

8. The efficiency of a two stroke engine does not depend on the effectiveness of the scavenging process.
