Q

What is the ineffective crank angle?

A

Where there is small linear movement of the piston for a large angular rotation of the crankshaft

17
Q

What is inlet valve lead?

A

When the inlet valve is opened early, at the end of the exhaust stroke

18
Q

What is exhaust valve lead?

A

The exhaust valve opens before the end of the power stroke

19
Q

What is exhaust valve lag?

A

The exhaust valve remains open after TDC an into the induction stroke

20
Q

What is valve overlap?

A

When both valves are open at the same time

21
Q

What is the ignition timing?

A

Ignite just before TDC so the whole charge has ignited by just after TDC
