How Jake Breaks works aka "Frenno"

Science & Technology

hii kitu imenisumbua niaje, i ask even truck drivers wananiambia ati sijui inafunga exhaust ndio gari inaisha nguvu, bla bla. mwingine ati ni pressure ile iko kwa breaks hydraulic tank hua inatoka.
Well imekua kibarua kwangu since mr.google dosent recognize the word “Frenno”

and here is the correct definition

A Jake Brake modifies the timing on the exhaust valves so that, when braking is desired, the exhaust valves open right as the piston reaches the top of the compression stroke. The energy gathered in the compressed air is released, so the compression stroke actually provides braking power.
Thank me later @kabudaa

Nice info. Have always wondered.

4

Those truck drivers were correct.There are like four variants of ‘retarders’

Saw a military truck speeding like a fighter jet ikipiga hizo frenno but it still crashed

6

They are not brakes.They only reduce speed.

mufler na whistler

8

But even the driver who talked about compressed air in the exhaust system were right.

Freno ni whistler?

Try driving an NPR downhill on 2nd gear and apply the engine brake/Jake breaks without using the brake pedal and you’ll realise how effective the jake brakes are… I used to descend a hill that was 5 km long using jake brakes only, my NPR used to move at a snails pace.

Is it true that hufai kutumia both brakes at the same time?? Hapa driving school sikuelewa…

As far as we were told by the Isuzu Japan guys (I was amongst the team that test drove the new NQR Isuzus), Jake brakes are supposed to be used on steep declines so as not to make the brakes hot, matatu drivers misuse Jake brakes…

13

now i understand their purpose. Then matatu drivers are simply attention seekers

Show-offs is more like it. I’ve seen many that don’t know how to downshift properly plus misuse of “frenno” makes me want to pluck out my pubic hairs.

It gets really annoying when they make those loud exhausts sound like they are sneezing

Many I’ve seen don’t know that in a traffic jam, they don’t need to use the accelerator or brake pedals, the clutch only will suffice, no wonder mats chapa quickly.

…the same matatu guys also use frenno kimatharau…they release next to your open window of a small car…anakujazia moshi ndani ya gari

whistler ni modified freno, ni exhaust inatengenezwa shimo ivi ivi then exhaust ikitoka inatoa a whistling sound
