Diesel smoke results from pressing too much on the accelerator, often a result of operating at too low an engine speed. It could be due to a lack of engine power, or overloading. Some drivers change up to the next gear around 2000 rpm, which may be too soon because the next gear starts at a lower rpm, where the engine may not have developed its full torque. Others may start off in 2nd gear, because they feel that first gear is too short. The result is that the accelerator is pressed too much, and with the low rpm, little air is induced, and it is not able to combine fully with the excessive diesel. Therefore, lots of smoke may be produced.
Our method of reducing diesel smoke is to increase the power of the air intake. We apply the Surbo, which induces more air at 1/2 half accelerator pressure, generating air jets which pressurizes the air. This effectively gives higher air compression, and yet moderates the diesel input, leading to improved combustion and reduced emission.
Surbo fitted in the pipe after the air filter of 2008 Peugeot Expert 2.0 turbodiesel, and testimonial from the owner.
We recommend that first gear be used, instead of second gear, for initial acceleration. The shorter gearing means it is easier for the engine to turn, and the Surbo's added air pressure means higher rpm is possible, so making this gear a useful gear for the open road. The diesel engine can reach 5000 rpm with just half accelerator pressure, due to the Surbo pre-compressing the air. As there is higher rpm, there is more air to mop up the diesel, so reducing diesel smoke. The higher revs means that subsequent gears start from a higher, stronger rpm, so that less of the accelerator needs to be pressed, keeping the smoke at bay.
So, if you have a diesel vehicle, and you need to get more power, save some diesel, reduce smoke, or all of the above, the Surbo is ideal for your vehicle. Contact us for a try.
