1. Time loss factor in Actual Cycle is due to ____________
a) progressive combustion
b) heat loss through cylinder walls
c) gas leakage
d) friction
Answer: a
Clarification: None.

2. If the spark timing is at TDC, the work is ____________
a) more
b) less
c) equal
d) none of the mentioned
Answer: b
Clarification: If the spark timing is at TDC, the work is less as the peak pressure is low.

3. When the spark is advanced, the work output is less as ____________
a) the peak pressure is low
b) the peak temperature is low
c) additional work is required to compress the burning gas
d) frictional losses increase
Answer: c
Clarification: When the spark is advanced, the work output is less as additional work is required to compress the burning gas.

4. Optimum spark timing gives ____________
a) higher mean effective pressure
b) higher efficiency
c) higher mean effective pressure and higher efficiency
d) none of the mentioned
Answer: c
Clarification: None.
