in some first world countries naman, like Canada, use of engine brake is restricted. when we were there, we were discussing about why it has to be so. it was mainly for the compression type of engine brakes pala, though it wasn't clearly indicated in the road signs.
i mean exhaust not engine braking. maingay kasi makina kapag nage-engine brake. sabagay yung exhaust brake eh usually sa trucks with big engines ang application. siguro yung mga Fuso, giga, similar sized trucks meron na ito dito sa pinas lalo na yung mga surplus trucks.

actually dito sa pinas given 3rd world technology, hindi naman talaga engine brake ang technical term kung titignan mo yung valve train lalo na kung diesel kasi hindi naman throttled ang diesel engine. yung gear ratios ng transmission kumbaga ang nagcocontrol ng speed (somehow making an effect similar to engine brakes). sa gas engine, pwede dahil throttled ang intake manifold nito.
