Piston compression height is the distance between the centerline of the pin to the flat part of the top of the piston. It's important to know this number when ordering pistons--especially custom ones- ...

“Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

As gearheads, we love to remember numbers. Many can probably rattle off all sorts of specs from various cars and engines. Cubic inches, rearend ratios, and camshaft lift specs are a lot of the common ...

The significantly poorer efficiency of a spark-ignition engine in the part load range compared to its efficiency at full load is the result on the one hand of the restriction losses and on the other ...

Improving engine efficiency and reducing the total cost of ownership demands engine friction loss reduction through optimal design, especially for large bore application considering the amount of fuel ...
