How do newer cars know when to fire certain cylinders?
Many modern cars have no distributor at all. The ignition is triggered by toothed timing wheels spinning with the crankshaft, which is much more accurate than points. Then there are individual coils for each cylinder, fired by the engine management computer. Some engines share coils between two cylinders.
What are the firing orders of a 4 stroke engine?
From figure 4 cylinder #1 fires in the first 120 degrees. In the next 120 degrees (240 degrees), as cylinder #1 moves from the power stroke to the exhaust stroke, cylinder #4 fires. In the next 120 degrees (360 degrees), as cylinder #4 moves from the power stroke to the exhaust stroke, cylinder #3 fires.
Why is the firing order of the engine fixed?
Cylinders firing order improves the distribution of the fresh charge in the manifold to the cylinders and helps the release of the exhaust gases,while at the same time reduces torsional vibrations. So after a proper introduction of firing order coming to the question. It is fixed so that torsional moment is even.
What is the firing order of a VW Jetta engine?
