Just back from Autodrom Most in the Czech Republic where we spent two days testing with the Race Truck of Rennabteilung der Heinrich Hecker KG in the run-up to the European FIA Truck Race Championship.
In this MAN truck is 1 of the D26E6 engines that I build and like every year, there are some changes in the regulations, so you have to adjust the engine management accordingly.
Again this year has a lot to do with the way they measure speed with the FIA race management. It is therefore important to get as close to the speed as possible and then you talk about 0.2Kmh determines which we can regulate and you also hear in the video that the motor reacts to every bump on the tarmac and that we also much faster on speed governing then the other teams that only use the GPS speed measurement from the FIA organization that a lot slower in response something that you can see in the data logs where we compare data from both GPS speed inputs.
Smoke at FIA truck racing is a No Go but the FIA European Championship is the F1 of truck racing. If you do not manage it well you and up on the back of the feeld and this max 13L engine capacity you can easily go over the 5000Nm torque and 1000Hp which can be much more but just like in the Rally Sport there is an inlet restrictor for the turbo compressor that limits the amount air that enters the engine. when it comes to power and torque with a race truck, you have a triangle to handle things best as for trying to inject too much fuel at high revs to make power you I get smoke. I try to inject a lot of fuel at low speed and you also try to make a lot of torque / power still have oxygen left to burn fuel smokeless but then there is a chance that the fuel pump cannot deliver this fuel, and yes we already have a fuel pump that can pump more fuel which also requires less power to do this compared to what other teams use but we also have a driver who is gaining experience by making a lot of race kilometers and a load more power means that the power itself in the last gear itself above 100Kmh just breaks traction ending up with drifting and skating the rear is not a problem only you will drive slower and yes there are enough buttons that you can turned that stuck to the engine management system to control the power per corner just like in Formula 1 car, but believe if you are all racing you need all the concentration and attention and therefore not all race drivers are able to turn knobs to set engine power as needed and it requires experience to do all of this during a race or you have to have very good control over your accelerator peddle.
Was a successful weekend with a compliment from an FIA official that we can participate between the teams that are supported by the factory, with the remark if an engine supplier pulls the plug on support then there are options for the racing teams to continue. So yes they are aware that a truck manufactured can pull out.
