Efficient range extender system: engine thermal efficiency of4596;The highest eficiency of the motor is 97.44%,and the averageeficiency of each powerpoint is 95%,leading intemationaly;
Ultra lightweight design:Lightweight cylinder head cover,oilpan,turbocharger intake pipe,allaluminum fiywheel housing
Modular design:Machinecooingmodule and modularintake of airthrough the crankshaft;
NVH:The surface sound pressure levels of the steady-state rangeextender at 20kW and 150kW power points are 70.5dBA and 90.2dBA,which are better than industry competitors;
Ultra low fuel cost:adopting advanced technologies such astheoretical air-fuel ratio closed-loop control and multi-point fuelinjection to optimize combustion,the engine has better fuel economy,lowoperating costs,and extremely high cost-effectiveness.Compared todieselengines,it can save 40.2%ineconomy;
High reliabilty:Adhere to the concept of high-qualitydevelopment,from a technical perspective CAE analysis andexperimental verification are considered from multiple dimensions toensure reliable product quality,B10 has a lifespan of≥1.5 millionkilometers;
Ultra low emissions:Methanol is recognized as a clean energysource.Compared to conventional fuels such as gasoline and diesel,methanol combustion is more complete and thorough,and itsemissionsinclude CO HC and NOx emissions have significantly decreased,with areduction of≥95%,achieving near zero emissions.
