[img]http://www.nopistons.com/forums/uploads/post-77-1053195111.gif[/img] [/quote] Do they have low torque because of the way this piston transfers its power to the crankshaft ? [/quote] It's part of it, the way the rotor moves means the force it exerts on the shaft is similar to a piston engine with short rods. The 16X has a new shaped housing with longer "stroke", which will lead to better torque figures. Having said that, mine's a shade under 300lb/ft at 3500rpm IIRC, so they're not so low. There's just more of a gap between the peak BHP and torque figures. [quote][i]Originally posted by Kerry[/i] [quote][i]Originally posted by CorsAsh[/i] equivalent 3.2l capacity as opposed to the 2.6l [/quote] What are the rules with wankel engines and when the owners can refer to them as a 1.3 or a 2.6? is it whenever it suits them :| [/quote] [quote][i]Originally posted by ed[/i] I think you refer to it as a 1.3 whenever you are showing off how powerful your engine is, buying a tax disk or getting an insurance quote. You refer to it as a 2.6 when you want to show people that you're knowledgable about them on internet forums. :P xx [/quote] They were all classed as a 1.3 when first built. I still believe that they are a 1.3, it's just that insurance companies and the DVLA prefer to get more money by saying they're a 2.6 and making up some rubbish about swept faces. Any that were registered as 1.3 before the DVLA decided to change its stance remain as such until the V5 is amended, say a respray or something, when it will usually come back with 2.6. Any new cars, i.e. RX8s, are registered 2.6 from the get-go, despite still using 13B engines, [quote][i]Originally posted by sand-eel[/i] its very strange how they don't seize up as the "bores" aren't oil'd. [/quote] That's because the engines have oil metering pumps, with injectors mounted inside the rotors, these spray oil onto the chamber walls to keep them lubricated. It's also why they burn more oil than a piston engine. Some people prefer to remove this system and "premix" instead, where you remove the OMP, and treat the engine the same way you'd treat a 2-stroke, by adding oil hen you fill the car up. [quote][i]Originally posted by ed[/i] But the modes of failure are much more well known on a piston engine as everyone who's everyone is making them and researching how to make them better. Perhaps if more people worked on rotars then they would be a lot better. [/quote] Exactly, see my comment earlier to jr. :thumbs: The thing with rotaries is there are only three vital moving components, so when something goes wrong with one of these, it's usually catastrophic.
