The heart of a diesel is the piston. It's design and ability to withstand intense heat and pressure is critical to your vessel's operation. Lugger 125, 140 and 170 series diesels from 400 to 1300 horse- power are the only engines in their class with one piece, nodular iron pistons. This metallurgical break- through gives you more power, longer engine life and lower fuel costs than engines with aluminum pistons. Here's how: • One piece design eliminates failures associated with two piece pistons. 1. Combustion chamber with centered fuel injection point thoroughly mixes fuel and air for more complete, clean combustion and fuel economy. 2. Iron is stronger and has a higher melting temperature than aluminum, allowing the top compression ring to be closer to the piston crown. The combustion dead zone is minimized and fuel economy is increased. • Equal thermal expansion of the piston and liner allows a closer fit, reducing piston slap. Engine noise is reduced. 3. Keystone shaped compression rings reduce carbon buildup and ring sticking during light load and idle speed operation. Fewer service calls. 4• Oil sprayed into the piston gallery cools the piston crown, allowing higher combustion temperatures for more power output per c.i.d., less exhaust smoke and more efficient use of fuel. • Tuftride nitrate surface treatment holds lube oil and prevents scuffing. 5. Massive wrist pin and wedge shaped connecting rod boss UUG3E* The Pro's Choice has a heart of iron. increases effective bearing area to carry higher firing load. More power output. • Strong but light. A 700 HP Lugger iron piston weighs only 8.7 lbs. A competitive aluminum piston is 7.6 and a two part steel/aluminum is 9.7. Iron pistons are just one of many technically advanced features making a Lugger the best marine engine value for your new vessel or repower project. Contact your regional factory branch or Lugger dealer for more information and engineering advice.
