3.2. Engine Number

3.2.1. Engine number position

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

□□□ ○ ○○ □ □

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.

1.6. Example of engine type:

“SQR473F” means a 4-cylinders, 73 mm bore , line gasoline engine manufactured by the CHERY Automobile

Feature Code

Bore

Differentiation code

Enterprise Code

Number of Cylinders

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.

The position of QR513 series transmission number is as shown in the figure:

3.3.2. Meaning of QR513 series transmission number

The number of QR513 series transmission consists of transmission type and serial number.

1). Transmission type

The transmission type consists of code QR, number of transmission gears, max transmission torque, feature

code and structure differentiation code.

A complete transmission type is as follows:

□ □ ○ ○○ □ □ □

Structure Differentiation Code

Feature Code

Max Transmission Torque (kg·m)

Number of Transmission Gears

where, ○ represents an arabic numeral, and □ represents an alphabet.

2). Serial number

The serial number consists of the suffix of assy part code number (AA for the part code number without suffix),

manufacture year code, month code, the number sequentially assigned by the manufacturer of the transmission

in the production month of this type of transmission and the start/end symbol *. The year and month codes are

performed according to Tables 3 and 4 respectively.
