Engine That

What determines the sound of the engine made using the engine brake Motorcycle?

When accelerating the engine makes sound, but using the engine Brake is another sound. What determines that sound? I'm talking about something like this: yes came to say 4000rpm and then released throtle without pulling clunch. It is not listed? It does not work as a car engine?

Very complex issue to discuss exactly & Full details here. Accel and Deccel are 2 different modes of practice, "Deputy universes "At Accel,,, taking speed is very and high volume. combustion chamber Pressure are high, and rising Ob / min Exhaust under pressure to the point that it represents flow limitation,,,, in the same way Side'sVaccum accept is limited by the mass volume demand. Gulp dose rate was reported in all the way to altmosphere On DECCEL,, Air intake is almost zero,,,, Carb & Down dose tract is under extreme vacuum until Carb intake near any quantity / atmospheric pressure condition. It is almost isolated from the atmosphere combustion is almost zero, therefore, pressure is limited to physical movement engine. And although hunger is Closed of the throttle. engine is pumping "No Air", to compress,,, No, to maintain combustion. PSI enter the exhaust fell over floor. What is "restrictive" Exhaust in acceleration, immediately becomes relatively caves in comparison with the mass of air conditioner must pass under Deccel. Or I should I say, lack of Reduced Air Mass Airflow,,, drops The speed of the exhaust outlet. In practical no back pressure exhaust,,, the "pop" the engine is transmitted through pumping exhaust with additional resonance due to the rapid Rise / Fall system pressure. Not reffering to lean misfire pop,,,, but popgun / type bottle cork dilution of the "pop" much more complex and complex than that,, but it all comes down the effect of air mass and pressure, speed and other terms of engine / Air dose / exhaust. All that behave quite differently during Accel / deccel
