Question 2.11 A/F effect on power output, efficiency and emissions for: a) constant speed b) constant throttle c) constant ignition timing
Answer: At constant speed the power output maximizes at ~ 12:1 A/F and drops off either side. The efficiency maximiz
Question 2.9 In the SI engine air and fuel are premixed and then compressed. Ignition happens (via a precisely timed electrical spark) just prior to TDC on the compression stroke. The mixture burns rapidly releasing most of its heat just after TDC (power
