High emissions
My Volvo 440 1.7si auto 1993 failed on emissions. The mechanic said this can be adjusted using the c.o. potentiometer. But he couldnt find it. He looked through the Haynes manual and it's not where it says it should be. He then said he thinks my engine has been replaced with a 2lt version. I looked for the engine number; when I got home; where it says to look in my owners manual. On my ownership papers my engine number has 1 letter then 12 numbers. Where I looked it had 1 letter and 6 numbers. Is this right? Is the Mechanic right?

Have a look on the front of the engine block, next to where the dipstick tube goes into the block, there may be a small metal plate about 1 inch x 2 inch with the engine series code stamped on it,
mine says B20F, if yours does it is the 2.0i engine. Last edited by andy100; Feb 13th, 2011 at 17:15. |

If yours has a cat converter and Lambda sensor then yours doesn't have the pot. meter on top of the air filter (or around there). If it's a 1.7i then the engine code for the catless version is B18EP while the cat. Lambda version is B18FP (basically same engines, just the latter has a cat converter and lambda sensor fitted, power is 102hp instead of 106hp.)
Why did it fail on emissions? Too high CO/HC (running rich) or high NOx (running lean)? Was it good on idle or was it bad in the whole rev range? |

Emissions results
Thanx for your replies. Fast Idle Test. CO failed. Max Limit 0.300, mine 0.552. HC passed. Lambda passed. Second Fast Idle Test. CO failed. mine 0.624. Passed the other two. Natural Idle Test. CO failed. Max limit 0.500, mine 0.585.
Looked by the dipstick, which is where i looked last time. The number began with what looked like a P then had 598441 after it. Not quite the B18! |

Hello B20F,
I'm trying to find the engine type in my 440. The 6th and 7th digit are 16. This is not covered in your list and the 480 Club site with the VIN reader gets all my vehicle details right, but says "unknown" for engine. It's a 1.8L so i'm guessing it's a B18(something). Do you know any other ways I can find out? Thanks. |
