Playing around with it might not be a very wise idea unless you really know your stuff. The wastegate is designed by the manufacturer for safe operation. At low engine speeds, you want the turbo to kick in early so as to reduce lag, and at high engine speeds, you want the turbine to not exceed its rpm capacity, which is achieved by closing and opening the wastegate (respectively). Without this mechanism, the turbo boost would keep on increasing and consequently blowing the engine. I'll not discuss more about the RD box as there's a separate thread dedicated to it.Īs for the turbo wastegate, it is there to limit the boost provided by the turbo. Adding more fuel will increase performance to an extent, and that power increase can be improved by adding more air as well (hence dual channel). The single channel box controls only rail pressure. The dual channel box IS designed for cars whose VGT turbo boost is controlled by the ECU. More fuel means more exhaust gases and that in turn means more boost. The bump in boost may be an indirect result of increased rail pressure. All the RD box does is to bump up the rail pressure to a more stoich/rich mixture based on the setting of the mode selector switch. Most stock common rail diesel engines run a little lean to meet emission standards. I'm not entirely sure how the RD box can manipulate turbo boost unless the turbo has an ECU controlled waste gate. Whenever the engine ( or boost pressure sensor) does not senses the expected boost among set limit tolerance based on operating conditions, you will have check engine lamp ON.

This is achieved through interpolation among the set defined limits.

The location shown is not boost pressure sensor.Ĭaution has to be taken while tweaking with turbocharger as engine software (maps) have a defined table of expected boost under any given condition of engine operation. Further to reduce the effect of the air getting hooter ( & thinner) due to compressing inter cooler is incorporated. So obvious option is to supply more air ( more oxygen) so that more fuel can be burned and hence more power. Power is directly proportional to amount of fuel burnt successfully.įor more power more fuel to be burned, but within limits of the stoichiometric air / fuel ratio (14.5 : 1 vol - slightly lean for diesel in practice for avoiding unburnt fuel or soot), the upper limit is by cubic capacity of the engine. (See Below) And, hence the turob charger keeps on developing boost as the rpm increases. So that no boost reaches the spring actuator, and hence the wastegate valve always remains closed. Maximum possible boost: The easiest way to achieve maximum boost is to, just pinch the boost sensor pipe (the black pipe). Increase the maximum boost: By reducing the length of the rod, you increase the preload, which means, more boost is required to open the wastegate valve and hence more maximum boost.īypass the turbo: For bypassing the turbo (no-turbo effect), just remove the pin, and uncouple the valve and spring mechanism. Now, y ou can turn the rod to increase and decrease its length.ĭecrease the maximum boost: By increasing the length of the rod, you can reduce the preload which means, lesser boost is required to open the wastegate valve. Loosen the nut shown in the figure below. Remove the pin or circlip which holds the rod to the valve. Hence, by this wastegate mechanism one can decide on what max boost one can run. When boost drops, the rod is pushed up by the spring which again closes the wastegate valve, and hence now, exhaust gases have to escape by doing work on the turbine wheel, which inturn builds up the boost. Hence, the compressor fins doesnt turn, and boost drops.

Opening the waste gate valve creates a bypass way for the exhaust gases to escape, without doing work on the turbine wheel. Pushing down the rod means opening the wastegate valve. The boost is built up in the compressor, and the black pipe, which can be called the boost sensor(?) conveys the boost pressures to the actuator, where there is a spring mechanism, which pushes down the rod. Usually what happens in a turbocharger is: Given below is an illustration of how you can adjust the preload setting of your turbocharger. Increase the max boost (at higher rpms).The best part is that, you can increase or decrease the boost, and hence increase or decrease the power of your turbocharged vehicle at home, with just a spanner and a plier. Most turbos in India (I guess.) come with an Internal wastegate which can be tweaked for different purposes.
