Product DesignationsEngine SeriesWaukesha manufactures five engine families — the ATGL, APG, VHP, VGF, and VSG.

Prefix DesignationsThe prefix attached to an engine model indicates the number of cylinders (except ATGL and

APG which states actual number): P = 16, L = 12, H = 8, F = 6.

• VHP L7042GL engine is a 12 cylinder engine

• VGF P48 GL is a 16 cylinder engine

• 16V-AT27GL is a 16 cylinder engine

Numeric DesignationsThe numeric designation in each engine model name indicates the displacement of the

engine model in either English units of cubic inches or metric units of liters.

• The ATGL series is designated by a numeric indicator of the bore size in millimeters.

For example: the “27” of the 16V-AT27GL indicates a 275 millimeter bore.

• The APG series is designated by a numeric indicator of the bore size in millimeters.

For example: the “150” of the 16V150LTD indicates a 152 millimeter bore.

• The VHP series show a displacement in cubic inches. For example: the VHP L7042GL

indicates a displacement of 7,040 in3.

• The VGF and VSG series show a displacement in liters. For example: the VGF P48GL

indicates a displacement of 48 liters.

• The VSG F11GSI indicates a displacement of 11 liters.

Suffix DesignationsG = Naturally aspirated

GSI = Turbocharged, intercooled

GSID = Turbocharged, intercooled, draw-through

LT = Lean combustion turbulence

LTD = Lean combustion turbulence, draw-through

GL = Turbocharged, intercooled, lean burn

GLD = Turbocharged, intercooled, lean burn, draw-through

Turbocharged, intercooled, rich burn
