Piston weight reduction




piston weight reduction

Psru Load Model, the concept of a Design Load Model, the severity of an aircraft load model, and the difference between aircraft and automotive load models.
Housing bore tolerances of /-.000050 (50 millionths) match some of the tightest accepted tolerances in the industry.
The medium speed 4 stroke trunk piston engine can be found on most medium to large merchant vessels even if the main engine is either a steam turbine or a 2 stroke crosshead engine.Example: A piston has.5cc effective dome volume.Compression Ratio Top Compression ratio (swept volume total chamber volume) / total chamber volume It is important that we understand two terms and their relationship to compression ratio: Swept Volume and Total Chamber Volume.Example 1: Engine Displacement 350 cubic inches, stroke Length.480 number of cylinders 8, cylinder bore diameter square root of engine displacement stroke.7854 X number of cylinders) Cylinder bore diameter 349.8486 / (3.480.7854 X 8) Cylinder bore diameter.000" Example.Swept volume (cc) cylinder bore diameter (inches) X cylinder bore diameter (inches) X stroke (inches).8704 Example: Cylinder head.18 cc Piston flat top with two valve pockets that measure a total of 4 cc Head gasket.000" round and.038" thick when.Diesel electric propulsion allows the engines to be placed wherever is most suitable, as they no longer have to be aligned with reduction gearing and shafting as is the case with conventional installations.Introduction to psru Technology, an introduction to the subject of psru's voyage cadeau mariage and why they are necessary.



Proprietary bolts produced by ARP to K1 specification have asymmetrical threads to equally load each thread when under pressure.
K1 Technologies also has the capability to make custom connecting rods made to your specifications.
The desired effective dome volume.5cc.
Frequently Asked Questions about psru's The questions about psru technology which we are asked frequently, (which you should ask any psru vendor from whom you are contemplating a purchase) and links to the answers.With such engines, which are termed trunk-piston engines, the engine height is considerably reduced compared with that of a crosshead engine of similar power and speed.This part of the engine has a huge amount of stress due to twisting and bending 1000's of times a minute while running under load, you dont want an inferior product here to ruin a motor.The engine-manufacturing costs are also reduced.Go to: Top of Page.The typical bearing loads encountered in a psru and how best to handle those loads.Direction of Engine and Prop Rotation The various tradeoffs which occur when the engine and prop rotate in the same and in opposite directions.



It was also the first of our gearbox products to use hydrodynamic bearings, which substantially reduced the weight of the package.
To remove.0cc, cut.6 grams (2.8) from the piston dome.
Wiseco engineers have worked in concert with K1 Technologies to design our crankshafts to meet or often exceed OEM tolerances giving you the best base for your bottom end rebuild.
