A crank angle detection device for an engine that includes a pulsar ring including a plurality of detection portions and rotating coaxially with a crank shaft of the engine, and a sensor detecting a passage state of the detection portions. Here, the pulsar ring is fixed to a crank web of the crank shaft. A weight for adjusting inertia balance of the crank shaft is fixed to the crank web arranged close to an end of the crank shaft in an axial direction. The weight has a shape obtained by increasing thickness of a part of the pulsar ring."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Crank angle detection device for engine","description":"A crank angle detection device for an engine capable of achieving downsizing and enhancing appearance of the engine is provided.
