Efficient range extender system: engine thermal efficiency of 45%; The highest efficiency of the motor is 97.44%, and the average efficiency of each power point is 95%, leading internationally
Ultra lightweight design: Lightweight cylinder head cover, oil pan, turbocharger intake pipe, all aluminum flywheel housing
Modular design: Machine cooling module and modular intake of air through the crankshaft
NVH: The surface sound pressure levels of the steady - state range extender 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 as theoretical air - fuel ratio closed - loop control and multi - point fuel injection to optimize combustion, the engine has better fuel economy, low operating costs, and extremely high cost - effectiveness. Compared to
Diesel Engines, it can save 40.2% in economy
High reliability: Adhere to the concept of high - quality development, from a technical perspective CAE analysis and experimental verification are considered from multiple dimensions to ensure reliable product quality, B10 has a lifespan of ≥ 1.5 million kilometers
Ultra low emissions: Methanol is recognized as a
Clean energy source. Compared to conventional fuels such as gasoline and diesel,
methanol combustion is more complete and thorough, and its emissions include CO HC and NOx emissions have significantly decreased, with a reduction of ≥ 95%, achieving near zero emissions.
