Understanding Port Swirl In Diesel Engines
What is port swirl? Actually this is a little contradictive. The port doesn’t actually swirl, it is the design of the port that causes air to swirl! Swirl is what is taking place when the intake charge exits the intake valve and enters the combustion chamber. As the air enters the combustion chamber and the
CNC?Head Porting & Machining Centers
The fact that CNC machines have come down in price over the years, coupled with less complicated interfacing systems means that today they can be used by nearly anyone.

Whether in a gasoline or diesel-powered engine, the crankshaft is a key component. With diesels, the crank is typically thought of as bigger, heavier and harder to get in the
A Closer Look at Today
The location of the wrist pins must match the stroke of the crankshaft, the length of the connecting rods and the deck height of the block.

Valve Spring Clarification There are many misconceptions on the visual inspection of valve spring free heights. There is a manufacturing tolerance on this dimension. The spring can change during the heat treat processes and squareness during the coiling process. Spring dampers can also influence the free length as they are installed before the spring is
Gaskets, Seals, Sealants and Fasteners
The factors that typically cause a gasket to fail include age, heat, thermal expansion, abrasion, pressure, vibration, corrosion, material breakdown or poor design. Some gaskets go the distance and others do not. With head gaskets, problems like detonation and engine overheating can damage the gasket very quickly, causing an otherwise good gasket to crack or
