      <title>M25: NEW 255MM BORE ENGINE FROM KRUPP MAK</title>
      <link>https://trid.trb.org/View/479935</link>
      <description><![CDATA[Simplicity, robustness and ease of installation were key priorities set by the designers of Krupp MaK's latest family member, the M25 engine, which is intended for small ship propulsion and mainstream genset drive duties on marine diesel or heavy fuel.  An output range from 1740 to 2700kW is covered by the M25 series with six, eight and nine-cylinder in-line models running at 720/750 rev/min.  The article includes a table giving the principal weights and dimensions for the engine and a cross section diagram.  See also the following abstract two abstracts.]]></description>

      <title>A NEW 250MM BORE ENGINE FROM MAK</title>
      <link>https://trid.trb.org/View/480629</link>
      <description><![CDATA[The article describes the M25 medium-speed engine just introduced by Krupp MaK Maschinenbau GmbH of Kiel, Germany.  The engine is a long-stroke 255mm bore unit which will be offered with six, eight or nine cylinders in-line covering the output range from 1,740kW to 2,700kW.  The M25 is intended as a propulsion engine for most types of smaller vessel, including general cargo, tugs, special tankers, ferries, passenger vessels, fishing vessels and special purpose ships.]]></description>

      <title>POWER TO WEIGHT - A VIRTUAL RATIO</title>
      <link>https://trid.trb.org/View/480866</link>
      <description><![CDATA[The propulsion system represents a significant proportion of a high speed vessel's weight.  Engine manufacturers are using the latest technology to improve the output of propulsion systems while reducing the overall weight.  Competition between the various engine manufacturers to supply the very lucrative high-speed ferry market is fierce and is divided into three main sectors: medium speed diesels; high-speed diesels; and gas turbines.  This article discusses some of the latest developments.]]></description>

      <title>EXPERIMENTAL INVESTIGATION ON EMULSIONS IN HIGH POWER MEDIUM- SPEED AND HIGH-SPEED SINGLE CYLINDER DIESELS</title>
      <link>https://trid.trb.org/View/479468</link>
      <description><![CDATA[The fuel saving effects of emulsions in diesels is discussed. Test results of emulsions obtained in high power medium-speed and high-speed single cylinder diesels are given.  Many of the tests were carried out using emulsions in high power medium-speed and high- speed single cylinder diesels.  The fuel savings are proven.  The maximum average saving of 3.46% may be achieved by using emulsified fuels in a high power medium-speed single cylinder diesel of model 280.  The maximum decrement of exhaust gas temperature was 50oC.  The variation of explosive pressure is not distinct.  In a high power high-speed single cylinder diesel of model 200 the maximum average saving of 2.28% was recorded.  The exhaust temperature lowers 40OC.  Maximum increment of explosive pressure of the order of 1.5% was achieved.]]></description>
