Daihatsu MD‑9M Oil Mist Detector

Daihatsu MD‑9M Oil Mist Detector

The Daihatsu MD‑9M Oil Mist Detector is a crankcase monitoring system designed to detect hazardous oil mist concentrations in medium‑speed marine diesel engines. It provides early warning against crankcase explosions, ensuring safe and reliable engine operation in demanding marine environments.

The Daihatsu MD‑9M Oil Mist Detector is a dedicated safety device engineered for continuous monitoring of oil mist concentration inside the crankcase of medium‑speed diesel engines. Designed specifically for Daihatsu marine engines, the MD‑9M helps prevent crankcase explosions by detecting abnormal mist density at an early stage and activating alarms or shutdown sequences according to engine safety protocols.

Using a multi‑point sampling system, the MD‑9M draws crankcase atmosphere from several compartments and evaluates mist opacity through an optical detection chamber. This ensures fast and accurate detection of rising oil mist levels caused by bearing overheating, lubrication failure or mechanical friction.

Built for harsh marine conditions, the MD‑9M features a rugged construction, high vibration resistance and reliable long‑term performance. It is widely installed on Daihatsu auxiliary engines used on merchant vessels, tankers, bulk carriers and offshore units. The system complies with marine safety requirements and supports integration with ship automation and monitoring systems.
