Three’s Company: Understanding Rod Length, Piston Compression Height and Crankshaft Stroke
The relationship between connecting rod length, piston compression height and compression ratio is often misunderstood, largely due to the misuse of the term “compression”. In all honesty it probably shouldn’t be applied to piston terminology at all except as it relates to the shape of the piston crown surface. Compression is a volume related term

Infiniti’s VC-T is the World’s First Production-Ready Variable Compression Ratio Engine
Infiniti will present VC-T (Variable Compression-Turbocharged), the world’s first production-ready variable compression ratio engine and one of the most advanced internal combustion engines ever created, on September 29 at the 2016 Paris Motor Show.
PERA’s First Webinar of 2016 to Feature New Coatings for Steel Compression Rings
Bill McKnight will present an all new webinar on OEM ring production designs and new coatings that have been developed and the processes used to apply them to the steel compression rings to reduce wear and resist heat. He’ll also cover materials in aftermarket replacement sets for late-model engines.
Checking Compression Ring Gaps
Minimum gap tolerances must be observed in order to prevent the ring ends from butting together as the ring expands when the engine approaches operating temperature. It is recommended that you use a minimum gap of .0035? per inch of cylinder diameter. Example: 4? (bore) x .0035 = .014 minimum gap. Maximum ring gap is
Steel Compression Rings with Reduced Radial Wall Thickness
MAHLE Clevite Inc. is in the process of transitioning its ring sets from a grey cast iron top rings to a carbon steel top rings. They say the advantages include 35% more strength, 30% less weight and double the resistance to side wear which is a common problem on late-model engines. The net result is
The Importance of Compression Ratios and How To Measure Them
NHRA Top Fuel and Funny car teams replace them after every race pass and every second qualifying pass. Pro Stock teams replace them after every 40 passes approximately, and weekend warriors replace them every 12 to 18 months, sooner if their engines are nitrous-assisted. At piston replacement time questions of spec changes usually arise –
Manganese Phosphate Coating on Compression Rings
This black coating is on the ring for two important reasons. The coatingis manganese phosphate. The reason rings are coated is twofold (1) rustprevention and (2) oil retention for protection against scuffing in early engine operation. Rust prevention is necessary for the period of time the ring is in the set box sitting on a
Magnum Cautions Gasket Installers About Compression Set
Of particular concern to engine builders and installers is that the appearance of good quality and poor quality molded gaskets can be nearly identical, yet they will have vastly different levels of sealing ability. The invisible difference between premium quality gaskets and those of lesser quality is the compression set of the synthetic rubber. Compression
Cold Weather Caution: Crank No Start, Rough Idle or Misfire due to Compression Loss
Models affected: 2000-2009 All GM Passenger Cars with Gasoline Engines 2000-2009 All GM Light Duty Trucks with Gasoline Engines Condition/Concern: Crank no start when cold. The engine may crank over very fast, as if there is low/no compression. It may also run rough for up to 5 minutes after starting the engine and may exhibit
Compression Ring Seating: When is a Piston Ring Seated?
So when is a piston ring actually seated? For a compression ring to seal against the cylinder wall it is important that line contact be established. The sketches below Illustrate cross sections of two popular types used in many ring sets. As can be seen in the illustrations, both the barrel face and the taper
How To Test Compression Drop in Hot or Cold Engine
This procedure could be a course of action taken inresponse to a customer complaint of engine miss, either hot or cold. Tofind out what cylinder is affected, complete the steps below. First, check the compression using standard procedures (remove all sparkplugs, open throttle valve, etc.). Write down the compression readings.Now, install all but one of
Diesel Drag Racing, Compression Ignition Engines Smoke The Strip
It is one of the purest forms of American motorsports. One guy pulls up next to another guy at the starting line and revs the engine. A simple glance over, a nod and a green light. In a fury of sound and smoke, the two racers take off down the straight stretch of pavement. If
Cylinder liner adjustment and compression ring gasket thickness for Detroit Diesel Corporation (DDC) 71 Series diesel engines
Engine Builders: The following information regards cylinder liner adjustment and compression ring gasket thickness for Detroit Diesel Corporation (DDC) 71 Series diesel engines. This information should be considered any time liners are replaced. AERA previously published TB 206 concerning compression ring gaskets. This supplements that information. The correct position of the liner top flange is
