wankel engine or normal engine
Discussion
wot are the advantages of a wankel engine, i heard they suffered from poor low end torque, i cant seem to find much info on them, the problem is, i can only find teh rx7 to get get any decent info on, and they have a turbo, and are already tuned, can rotary engines be designed for good mpg too,
the problem as i c it, with the rotary engine, when the combustion takes place, there is a large surface area, to get rid of heat ( conduct) so lots of energy is lost in heat, if u can coat , or make the rotor out of a material with a low thermal conductivity, and the rotor's case( not sur eowt it is called) out of a similar material but with low friction, then more of teh energy can be turned into kinetic energy, and therefore more torque, and there more power
i no the new rx 7 has a compression ratio of 9:1 but how could this be increased, assuming, that no detonation or pinking would occour, wot physically could be done to increase the ratio , could a ratio of 15:1 be achieved, could this be done by creating a cavity at the top of the cylinder just after th einlet port, and just before the closing point when it sparks, so that a bigger compression be acheived,
ceramics are good, but they dont really posses the streghts of metal, a good marsenite metal, with a coated properties of low thermal conductivity would be best, for instannce the strongest ceramic zirconia, has nearly same strength as un forged steel, so for performance the coating would be best, but zirconia isnt as good at thermal conductivity as silicon carbide or double bonded silicon, also double bonded silicon has a very low friction co efficent,
