However, whenever you notice thick bursts of white smoke coming from exhaust, it is a sign that something is wrong with various components of your engine, whether it’s white smoke from the exhaust on startup or white smoke from the exhaust when accelerating....
Energy, or accelerating pressure, required to accelerate the air to the duct velocity. • Resistance of the exhaust ducting, which is determined by the total length of straight ducting plus the number and type of elbows. The exhaust fan and the motor shall be sized to the amount of effluen...
I’m perhaps in a minority here but I’m perfectly happy that my 650 isn’t outrageously loud when accelerating hard. I love that it’s very quiet when driving around normally with a nice deep but restrained V8 burble. However it’s alter ego can be induced when accelerating hard and ...
A broken manifold gasket can sound really noisy, particularly on cold starts or when you are accelerating. If your engine starts to make an unusual tapping sound which becomes louder on cold starts or on acceleration, you need it fixed because it won’t get any better on its own. Burning ...

The valve is opened widely when accelerating so that the exhaust noise is louder. Moreover, since the exhaust gas is exhausted to the sub-duct having lower air resistance than that of the inside of the muffler, the introduced air meets resistance so that it is difficult to put the exhaust...
Noise I think is more governed by mufflers and silencers and not pipe diameter. In any case I don’t believe that, in turbo cars, bigger is universally better, regardless of what someone trying to sell bigger pipes tells me. The laws of physics don’t change when a turbo is introduced....
A separate muffler may be coupled to the exhaust outlet to control noise, while a catalytic converter assembly may be placed in the exhaust fluid path to reduce the concentration of non-particulate pollutants. Although particulates may not generally be a concern in the small gasoline engine, some...
When the concentration measurements are deconvoluted, the noise is enhanced, as is typical during deconvolution [76], but when fitted to Equation (4), it takes the expected form as most of the value will not be affected after deconvolution. Deconvolution tends to overemphasise the peak values,...
when heated in the middle of the catalyst [64]. Moreover, when the concentration of CO in the exhaust is high, electric heating can promote the rapid release of heat from the catalytic reaction, thereby accelerating the catalyst ignition process. When the CO content in the exhaust is below ...
