This code allows the study of EHD lubrication of four cylinder in line engines.
Under LSWR and Southern Railway ownership they had been successful suburban passenger engines, although with the increased availability of newer, standard designs, many of the class were diagrammed to take on a new role as reliable branch line engines, especially in Southern England.
The only hope for V-8 salvation was blowing up or wearing out that in-line engine.
Each connecting rod in an in-line engine or each pair of rods in a V-type engine is attached to a throw of the crankshaft.
The crankshaft for an eight-cylinder, in-line engise is designed with each of its eight throws a quarter turn away from another throw.
The in-line engine has a single row of cylinders extending vertically upward from the crankcase and aligned with the crankshaft main bearings.
Four to eight cylinders may be aligned one behind the other in an in-line engine; the cylinders may be upright or inverted, the inverted having the crankshaft above the cylinders.
A transversely mounted in-line engine frees up more "crush space" than a V, adding a safety margin in collisions, according to Volvo, which uses transverse in-line fives and sixes in its S80 sedan and XC90 sport utility.
For best lengthwise balance, the cylinders whose pistons are in phase are the first and last cylinders of an in-line engine, the second and next to the last, continuing in that order with crank throws that are in alignment equidistant from the centre of the engine.
In addition, cycle fuel injection quantity is tested online and off-line engine operation.
It is known that there will be several new Eights, one the product of a large maker who is entering this field for the first time, with an in-line engine; another, of the V-type, will be shown by another manufacturer, whose product up to now has been confined to the Six field.
