Which feature does a typical crankshaft trigger wheel have?

  • A.Sixty teeth with two missing
  • B.One tooth for each cylinder, which produces a pulse at the moment each piston reaches top dead centre
  • C.A single tooth
  • D.Thirty six teeth with one missing, which is an equally common arrangement giving a resolution of ten degrees

Answer: A

The sixty minus two wheel gives six degree resolution with a recognisable gap for reference. Thirty six minus one is genuinely another common pattern, which makes the last option a correct description of a real alternative. Reading the definition literally, rather than recalling a summary, avoids the usual confusion. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision.
