Title:
2サイクルエンジン
Document Type and Number:
Japanese Patent JP4194007
Kind Code:
B2
Abstract:
An outboard motor includes a sensor assembly having a housing with a sensor chamber, a sensor having a sensor element exposed to the sensor chamber, and a sleeve disposed in a passage extending from a combustion chamber of the outboard motor to the sensor chamber. The sleeve can have three flanges supporting the sleeve within the passage. Additionally, the sleeve can have an extension so as to allow the overall length of the sleeve to be varied in accordance with the desired resonance frequency of the sensor chamber. An engine of the outboard motor can also include a control system configured to control an air/fuel ratio of fuel charges delivered to a combustion chamber within the engine based on an output of the combustion condition sensor when the engine is in a first operational state and to control the air/fuel ratio, irrespective of the output of the combustion condition sensor, when the engine is in the second operational state.
