A) Direct injection gives better fuel economy AND more horsepower. Its the best of both worlds. Most German car companies are using it now because the EU is mandating better CO2 emissions and its an effective method of reducing them. The extra power is just a side benefit of being able to run higher compression.If they can manage at least 25 mpg with tighter control of the ECU and direct injection, it will be viable.
I still can't believe after adding direct injection, variable valve timing on the intake and exhaust, and turbocharging...the new Cobalt SS still gets 30 mpg with 260 hp and 260 ft*lb torque...let us not regret going with the rotary Mazda...or else this fcuking thing will beat you off the line:
That's rotary though.yup a 1.3L engine making more horsepower than a typical 3.0L V6 while weighing 90 lbs less with a lower center of gravity and mounted further back is just horrible.
Lets see what Toyota can do with 1.3L . . . .
http://en.wikipedia.org/wiki/Toyota_NZ_engine . . . . oh . . 85 hp. Sweet.
They DO make 2-stroke piston engines, granted you won't find them under the hood of any car.Piston engines on the other hand, has 1 power stroke every other revolution of the crank.
they burn gas and oil, which is a small price to pay for a motor that is so physically small and light (allowing it to be mounted lower and further back for better weight distribution and rotation characteristics).AFAIK, though the 13B engine has a small displacement, it's how the rotary engine works that makes the difference.
It BURNS gas like no tomorrow, because it's a 2-stroke in that all 4 cycles that happen on 1 revolution of the combustion chamber, meaning it has 1 power stroke for every revolution of the crank.
Piston engines on the other hand, has 1 power stroke every other revolution of the crank.
I forgot the site I read it from, but a 1.3L rotary was getting the same MPG as a 2.6L V6 piston with the same power output.
:laugh:I can no longer hold this back any longer, nor can I try to explain it away in my head any more, so here goes:
I am fully convinced you are mentally retarded.
Sources close to Mazda told Inside Line today that the next Mazda RX-7 is still in the works. Inside Line has also learned that a new Mazda RX-8 is also in the works and is expected to be called the Mazda RX-9.
Mazda will not let the rotary engine die with the current RX-8, sources tell IL. The company is well along in development of its next-generation RX-7, fitted with a front midship-mounted 16X rotary engine. The engine will generate upward of 270 horsepower from a normally aspirated power unit, they say.
Engineers are also reportedly working on weight issues. By developing a new chassis, they have been able to shed some 220 pounds, reducing the RX-7's curb weight to the 2,640-pound range, according to one source.
