How To Reduce Diesel Smoke

Usually, as diesel engines age, they become less efficient and begin to emit black smoke. This has been observed in Singapore, where diesel taxis were clean when new, but as the mileage piled up, they have been noted to emit fumes upon acceleration. This was seen even for modern turbodiesels. Due to lesser power than required for the load, the driver may step excessively on the accelerator, which causes the diesel pump to deliver a lot of diesel into the engine instantly, but as the air intake may not be able to supply added air just as quickly, some diesel may not get burnt in the cylinders and will exit the engine as soot. Not only is this pollutive, it is also costly as fuel is lost, and there is also a warming effect on the environment, diesel smoke having a greenhouse effect similar to CO2.

One way to counter this is to add a Surbo to the air intake of the diesel engine, at the air filter section. The Surbo will raise the air intake power as it creates a deep-suction vortex which compresses air, and this raises the torque and power of the diesel engine immediately, even at idle, shown by a higher idling speed. The driver would be able to move the diesel vehicle with less pressure on the accelerator due to the added air compression. Note that improved engine compression (in this case through higher air compression from the Surbo) directly results in an increase in engine efficiency, which means the engine will put out more power for the same amount of diesel put in. The diesel engine will also be able to rev to a higher rpm for the same accelerator travel, so that it can latch on the the next gear at a higher rpm and thus avoid over-stepping on the accelerator and so cause black smoke emission. The torque spread on a Surbo-equipped diesel is also wider, meaning more torque even at a low rpm, so the driver can shift up earlier too, if desired. Downshifts can be made quickly and smoothly because the air supply from the Surbo is ready to meet sudden spikes in air requirement, and its air pressure holds the engine preventing it from losing too much rpm when the accelerator is released during a gearchange.

The Surbo can also be used on turbodiesels, helping the turbocharger to spool up earlier as the compressed air from the Surbo, even from a low rpm, is akin to having more air through the exhaust, and this increased exhaust gas turns the turbocharger up to speed earlier, and so it is able to provide boost from a lower rpm. In a sense, this reduces turbo lag.
