DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards. [pdf]
The fact is that oil inside the intake manifold, in whatever amounts it may be present, is just a portion of what flows through it when the car is running. Most of these oily fumes will get into the engine, where th. [pdf]
