CTOnews.com February 7 news, Dongfeng Motor announced this morning. With the highest effective thermal efficiency of 45.18%, Dongfeng's new Mach 1.5T hybrid engine has been certified as the "Energy efficiency Star" certified by Sinochem Huacheng, and has become the first hybrid gasoline engine in China's automobile industry with a thermal efficiency certification of more than 45%.

Dongfeng Motor said that the new Mach 1.5T hybrid engine, which has the characteristics of high thermal efficiency, high power and high responsiveness, will be carried in Dongfeng's new models in 2023, bringing users a more cost-effective car experience.

CTOnews.com query found that, in general, the higher the engine thermal efficiency, the lower the carbon emissions and user fuel consumption under the same power output. In general, every 4% increase in engine thermal efficiency reduces user fuel consumption by at least 10%. In other words, the same hybrid could have traveled more than 1200 km with a full tank and more than 1300 km after a 4 per cent increase in thermal efficiency.

The new Mach 1.5T hybrid engine boasts eight technical advantages:

The efficient anti-knock fast combustion system greatly increases the combustion speed and significantly reduces the knock tendency of the engine.

Hybrid special VGT (variable cross-section turbocharging) technology can effectively meet the efficiency needs of users in economic zone and power zone.

Low voltage EGR (exhaust gas recirculation) global coupling control technology realizes ultra-high EGR rate control of physical limit and self-correction of EGR rate in different environments.

350bar in-cylinder direct injection system greatly improves fuel spray atomization and particulate matter emissions, makes it more energy-saving and environmentally friendly, and has the emission potential of country 7.

Intelligent thermal management system independently develops the interactive strategy of engine thermal management and air conditioning thermal management to achieve the lowest pump power consumption to meet the daily needs of users.

Comprehensive electric intelligent solution, integrated more than 30 intelligent friction technologies, higher efficiency

The leading noise reduction technology in the same level makes the engine idle noise only 57.5dB (A), which is quieter and more comfortable.

The bottom layer and application layer software are developed independently, and the software strategies and functions are tailored to fully activate the hardware potential to meet the needs of users in the full scene.
