[edit] Oldsmobile-based Diesel engines
The first sentence of the second paragraph is a bit of cause for some concern. It used to read as follows:
- Due to the fact that they were based off of standard gasoline engine designs...
but now reads:
- These Diesel engines were designed to fit into the engine bays of gaoline powered automobiles, but despite popular belief, they were not "converted" gasoline engines...
Is it accurate to say this? The reason I ask is that they're essentially beefed-up versions of standard Olds V6/V8 gasoline engine blocks, albeit with big-block sized main journals. While there are some differences, they're basically modified versions of their gasoline counterparts, aren't they? I'm inclined to change it back, but looking for arguments against doing so.--King V 18:41, 23 May 2006 (UTC)
[edit] SKU codes
GM six-letter engine coding system explained (courtesy http://www.topbuzz.co.uk/info/engine_codes/engine_codes.htm)
|
What are 'engine codes'? Every engine in the GM range (i.e. includes Vauxhall, Opel etc.) has a engine code which represents the type of engine, its fueling type and its cubic capacity (cc in litres). So what is the code system? Each engine code usually begins with a letter, followed by 2 numbers and then either 2 or 3 letters after that. Lets take the following example: C20XE This is the engine code for the 2L 16v, DOHC, fuel injection engine as found in the Calibra, Astra and Cavalier cars. Lets split the engine code up. The letter 'C' is the type of exhaust or emission level standard. In this case C = EEC R 83. The next 2 numbers is the engine cc, which is 2000cc (i.e. 2L). The next letter (X) is the engine compression ratio, in this case X = 10.0 to 11.5. The letter E is the fueling system, which E = multi-point fuel injection (petrol). Where do I find the engine code? The engine code shall be stamped below the cylinder head (up to 1993), usually on a small flat surface. But after 1993 the location moved to the edge of the cylinder block, transmission side. |
| Engine Code System: | |||
|
The engine code system takes the following standard (Petrol engines): ABBCDE ie C20LET is a 2L Turbo injection engine with a CAT and a compression ratio of 8.5 to 9.0. |
The engine code system takes the following standard (Diesel engines): BBDEE ie 23DTR is a 2.3L Turbo diesel engine with increased output. |
| Code A |
Exhaust Emission Unit
|
Code B |
Engine Size (cc)
|
|
| C | Catalytic converter (EC 91/441/EEC, US ' 83) | Two digit number represents the litre of the engine size, i.e. 20 is 2.0L and 35 is 3.5L. So engine size in litres x 10. | ||
| E | Euro I | |||
| T | Euro III | |||
| X | Euro II (EC 91/441/EEC, stage 2 #, US '93-94) | |||
| none | ECE R 83 A (as R 15.04) | |||
Note: * = any character, # = Stricter limits for ca.1996
| Code C |
Compression Ratio
|
Code D |
Mixture system
|
||
| G | <= 8.5 | E | Multi-point Fuel Injection | ||
| L | > 8.5 to 9.0 | Z | Central Injection/Throttle Body Injection (TBI) | ||
| N | > 9.0 to 9.5 | D | Diesel | ||
| S | > 9.5 to 10.0 | L | Liquified Petroleum Gas (LPG) | ||
| X | > 10.0 to 11.5 | V | Carburettor | ||
