Engine Frames Bearings Shafts
Engine Frames. Bearings. Shafts. Flywheels. Engine The Matter Of Frame Design, Each Engine Builder Has Followed His Own Ideas. Unlike Steam Engine Manu Facturers, Hardly Any Two Low-pressure-engine Builders Use The Same Design Of Frame. However, All May Be Separated Into Two Types—the Open Frame, Where The Scavenging Air Is ...
Exhaust Pipe And Pit
Exhaust Pipe And Pit. Water Cooling Systems Exhaust Planning The Installation Of A Low-pressure Oil Engine, The Exhaust Piping Should Be Made As Short And Direct As Possible. All Elbows That Are Not Absolutely Necessary Should Be Eliminated. In A Horizontal Engine Plant The Best Pipe Layout Has The Exhaust ...
Fuel Nozzles Water Injection
Fuel Nozzles. Water Injection Fuel Fuel Nozzles Used On Low-compression En Gines Show Much Similarity Of Design. Unlike The Diesel Nozzle, There Is But Little Attempt To Thoroughly Atomize The Fuel Charge As It Leaves The Nozzle Tip. The Chief Use, Apparently, For The Nozzle Is Its Service As A ...
Fuel Oil Specifications
Fuel Oil Specifications Heat Value.—not Less Than 18,500 B.t.u. Per Pound. Contractor Must Give Low Heating Value Of The Fuel Supplied. Gravity At 60° F.—with Engines Having Closed Fuel Nozzles The Oil Shall Not Be Heavier Than 20° Baum& For Engines Having Open Nozzles The Oil Should Not Be Heavier ...
Fuel Pumps And Injection
Governors, Fuel Pumps And Injection Nozzles, Types, Adjustments And Repairs A Smooth-running, Efficient Engine Is To Be Pro Duced, The Designs Of The Governor And The Fuel Pump Must Be Co-ordinated. Indeed, Many Engine Builders Have United These Two Mechanisms Into One Design. For This Reason It Is Advisable That ...
Installation Of An Oil
Installation Of An Oil Engine General.—the Average Engineer Takes Up The Problem Of Installing An Oil Engine With A Feeling Of Foreboding And Dread. This Is Due To His Inexperience In This Character Of Work. It Is Not An Impossible Task; Indeed, It Can Hardly Be Termed Difficult If The ...
Installations
Installations Considerable Misapprehension Exists Among Oper Ating Engineers As To The Oils That Are Suitable As Fuel In A Low Pressure Oil Engine. It Is Unfortunate That Many Extravagant Statements Have Been Made Concerning The Results Obtained With Low-gravity Oils. An Operator Should Understand That An En Gine's Adaptability To ...
Low Pressure Engine Cylinders
Low-pressure Engine Cylinders Cylinder Cylinders Used On Two-cycle Low-pres Sure Engines May Well Be Separated Into Two Classes—those Having The Crankcase Enclosed To Act As A Scavenging Air Compressor, And Those. Which Make Use Of The Front End Of The Cylinder For The Same Purpose. However, The General Designs Of ...

Because Of Defects Of Operation In The Internal Combustion Engine ...
Operating Difficulties
Operating Difficulties Problem Of Lubrication Is One Of The Most Im Portant That Confronts The Diesel Engineer. Many Individual Engines Have Achieved A Sorry Reputation Due To Poor Lubrication Facilities Or To Mediocre Grades Of Lubricating Oils. The Engineer Does Well To Insist On A High Quality Of Oil, And ...
Piston Pins And Connecting Rods
Pistons, Piston Pins And Connecting-rods Types Of Pistons.—while The Majority Of The Two-stroke-cycle Engines Of The Low-pressure Type Use Pistons Having Deflector Lips, Similar To Fig. 259, There Are Several Other Designs Coming Into Vogue. Quite A Number Adopt The Double Piston, Fig. 260. This Piston, As Shown, Has Part ...
Pistons And Piston Pins
Pistons And Piston Pins Pistons Of All Engines Properly Fall Into Two General Classes—crosshead And Trunk Pistons. The Crosshead Piston Is Usually Shorter Than The Trunk Piston And Is Provided With A Crosshead Which Receives The Side Thrust Due To The An Gularity Of The Connecting-rod. Figure 49 Illustrates This ...
