Chris-Marine AB has launched a new Liner Diameter Measurement Instrument (LDM) in order to quickly investigate the condition in cylinder liners for 2-stroke engines. The main advantage of this new LDM is that the cylinder head or exhaust valve housing does not need to be removed. By replacing the traditional internal micrometer, the LDM is inserted in the liner through the scavenging ports.

The LDM can be preset with engine data for most of today’s existing 2-stroke engines, weighs 3.6 kg and is suitable for 2-stroke liners with a bore between 500 – 980 mm. Up to 12 measured diameters can be obtained on each level in the cylinder liner. The system accuracy is better than 0.03 mm and the total time to measure is approximately 1 hour per liner for measurement of 4 diameters on 9 heights (of which the setup time is about 20 minutes).

The system consists of the actual measuring unit and a wireless hand held terminal. Measured data is transmitted via a radiolink to an antenna inserted in the start air valve pocket. The stored data can be transferred to an excel application in any PC by Bluetooth, USB or by SD-card.

The instrument with radio transmitter has a CE-label, which is required for use within EU and Turkey. Further tests will be carried out for verifying compliance with other standards, of which the most immediate are USA, Japan, China and Korea.
