1).
Number of SQR473F series engine is printed on the boss of cylinder body near the engine exhaust side oil
cleaner (as shown in the figure below).
2). Number of SQR472F series engine is printed on the boss of cylinder body over the engine exhaust side oil
cleaner (as shown in the figure below).
3.2.2. Meaning of Engine Number
As shown in the figure above, the engine number located at the engine block consists of engine type and serial
sumber.
1. Engine type
The engine type conforms to the requirements of GB725, which consists of enterprise code, number of engine
cylinders, bore, feature code and differentiation code.
A complete engine type is structured as follows:
Engine No
Engine No
□□□ ○ ○○ □ □
where, ○ represents an arabic numeral, and □ represents an alphabetic character.
1.1 The enterprise code is fixed as SQR;
1.2 The number of engine cylinders is a 1 to 2-digit integer;
1.3 The bore is the diameter of cylinder barrel, expressed by a 2 to 3-digit integer, and its decimal is rounded to
ainteger with the unit of mm according to the rounding principle.
1.4 Feature code: Represent the basic feature of an engine, expressed with a capital English alphabet, and its
meaning is shown in Table 1. If multiple features in Table 1 appear at the same time, a feature code is choosed in turn
according to the sequence specified in Table 2. In case that the line engine’s basic feature code L is omitted, the other
feature codes in Table 2 can be choosed in turn according to the sequence of these codes.

1.5 Differentiation code: Expressed with a capital English alphabet, used as a complementary code to differentiate
the type of engine when all the number of engine cylinders, bore and feature code are the same while the structure,
main parameter(s) or fuel supply method and etc change (e.g., the change of engine stroke, bifuel engine, etc). For
the change of engine’s peripheral parts (such as intake and exhaust manifolds), the engine type is invaried but
differeniated by changing the number of engine assy.

Co., Ltd., which is a four-valve multipoint injection engine (the line gasoline engine feature code “L” is omitted
and then is occupied by the “four-valve multipoint injection, and the first structure differentiation code A is also
omitted).
2. Serial number
The serial number of an engine consists of engine feature code, EFI system manufacturer code, manufacture
year code, month code, the number sequentially assigned by the manufacturer of the engine in the production
month of this type of engines and the start/end symbol *. A complete serial number for an engine is as follows:
* □ □ □ ○○○○○ *
Month Code
where ○ represents an arabic numeral, □ represents an alphabet, represents an arabic numeral or alphabet.
2.1. The engine feature code is performed according to the provisions in paragraph 2.1.4.
2.2. EFI system manufacturer:
C – Motorola; D – Marelli; E – Delphi; F – United Automotive Electronic Systems (UAES) Co., Ltd.;
G – Siemens; H – TROITEC Automotive Electronics Co., Ltd.; B – Bosch
2.3. The year and month codes are performed in accordance with Tables 3 and 4 respectively.
