IDENTIFICATION
Engine Information Plate
The E-Tech™ engine information plate is located
on the top of the front cylinder head cover (back
cover for LE and MR chassis). This plate includes
information concerning:
r
Engine model, serial number and 11GBA
part number.
r
Advertised horsepower at rated speed rpm.
r
Emissions regulations to which the engine
conforms and other pertinent information
required by emissions regulations.
r
Inlet and exhaust valve lash settings and
engine brake slave piston lash setting.
The following explanations are provided to aid in
interpreting some of the key information found on
the engine information plate.
Block 1 — U.S. EPA Regulations
r
An “X” in block one means the engine meets
United States EPA regulations for the year
stamped in block four.
r
Two dashes in block one indicate the engine
does not meet United States EPA
regulations for the year stamped in block
four. This is only permissible with certain
export engines. All domestic engines will
have an “X” in block one.
Block 2 — California Regulations
r
An “X” in block two indicates the engine
meets California emissions regulations for
the year stamped in block four. This engine
is referred to as a “50-state” engine and can
be sold in any state throughout the U.S.
r
Two dashes stamped in block two mean the
engine does not meet California emissions
regulations. If an engine has an “X” in block
one and two dashes in block two, it is
referred to as a “49-state” engine, meaning it
is not certified for sale in California.
Block 3 — ADR Regulations
r
An “X” in block three means the engine has
been certified to meet Australian emissions
regulations.
r
Two dashes in block three mean the engine
does not meet Australian emissions
regulations.
Block 4 — Model Year
r
The four-digit number stamped in block four
represents the year in which the engine was
certified.
Block 5 — Federal Family
r
A 12-digit number stamped in block five
denotes the Federal Family to which the
engine belongs for emissions certification
purposes.
r
All domestic engines will have a 12-digit
Federal Family number in block five.
Block 6 — California Family
r
If the engine meets California emissions
regulations, the same 12-digit number
stamped in the Federal Family block is
stamped in block six.
r
If the engine does not meet California
emissions regulations, there will be two
dashes in block six.
Block 7 — Initial Injection Timing
r
E-Tech™ engines do not have an initial
injection timing, as this is controlled
electronically.
r
E-Tech™ engines will have “NA” stamped in
block seven.
Block 8 — Engine Brake
r
This block is only used when the engine is
equipped with an engine brake. The
stamping in this block indicates the engine
brake slave-piston lash setting.
