to be able to run rcci, combustion pressure based control (cpbc) is a requirement. only with cpbc the combustion temperature can be controlled above the ch4 oxidation limit and under the nox formation limit. the working method of controlling the combustion process based on the combustion temperature is patented by arenared. the cpbc-technology is executed on the special chip designed by arenared. this chip controls cpbc and with that it also monitors and analyses every combustion cycle and gives the engine feedback to obtain the best possible combustion quality.
the feedback control ensures that the engine always runs within its limits over the entire life time of the engine. this optimal adjustment also extends the lifetime of the engine. cpbc is fundamental in arenared' s technology and uses uniquely designed electronic control units (ecu+chip) and in-cylinder fiber optical combustion pressure sensors (cps), both designed and produced under arenared supervision.
one of the greatest advantages of arenared's cpbc is the high grade of fuel flexibility. with help of the combustion pressure sensor (cps) the electronic control unit (ecu) detects the chemical properties of the used fuel. if the fuel properties are within the prescribed specs, the injection strategy will be adapted accordingly. this enables the use of a wide variety of fuels that are also allowed to mix in one tank.
arenared is the only company in the world that has developed a special chip for rcci. this chip replaces 224 computers required for rcci operation on 1 engine. arenared is 8 years ahead of the industry.
with arenared rcci you can meet all emission standards now and in the future, without scr and therefore without urea addition. emission standards such as stage-v (eu-nrmm), euro-6d and soon also euro-7. rcci is also promoted by the technical universities of wisconsin, eindhoven and lund.
the user has the option to run arenared rcci on lpg, propane, gasoline, methanol, ethanol and ammonia in random mix from 1 fuel tank that resembles a stainless steel lpg tank.
at rcci you need 1% diesel for ignition, other fuels used for this technology can be biodiesel or e-diesel. the combustion of diesel in a classic diesel engine takes place from the liquid phase, this gives soot and nox . the combustion at rcci takes place from the gas phase. arenared also controls the combustion based on the combustion temperature, which is derived from the pressure and volume above the piston. this means that no soot and nox is produced during the arenared rcci combustion. rcci is ultra-clean, ultra-efficient and ultra-quiet.
