Talk:Toyota B engine

engine code

The recently introduced (14 Jan 2008) paragraphs about engine codes partially duplicates information at List_of_Toyota_engines and partially contradicts it (F and E codes). I have verfied that List_of_Toyota_engines has correct definitions for the E and F codes for petrol engines. Does this article need correcting or does List_of_Toyota_engines need more detail for diesel engine? Stepho-wrs (talk) 04:01, 15 January 2008 (UTC)[reply]

2B

It says the 2B has 93 HP at 2200 rpm, but that seems incorrect compared to the other B series engines, and should probably be around 3500 rpm. Vince (talk) 10:02, 27 August 2011 (UTC) And on closer inspection, the HP seems incorrect too, how can the smaller 2B be more powerful than the 3B? Vince (talk) 10:05, 27 August 2011 (UTC)[reply]

I don't know that true values for the 2B or 3B but the 2B has a higher compression ratio than the 3B. Since the 3B is only a little bigger than the 2B, it is quite possible that the 2B has a little more power. Size is not the only indicator of power - compression ration, valve timing, injection timing/pressure and many other factors determine the final HP figure. However, it does look like the 2200 rpm for max torque value was used for both torque and HP. The true rmp for max HP is probably in the 3000-3600 rpm range (ie similar to the rest of the range) but I don't know the exact value and I prefer no value rather than a guessed value.
