Intake Stroke
The intake stroke is one of the movements in the four stroke engine cycle. It begins when the piston is at top dead center. The exhaust gases have just been expelled. The intake valve opens, and the
Running Lean
When the proportion of fuel in the fuel/air mixture is reduced, the engine is said to be running lean. The engine is not receiving enough fuel for proper combustion. This will result in diminished pe
