What engine is used in the Mazda3 Xingcheng?
1 Answers
The Mazda3 Xingcheng adopts the world-advanced all-aluminum MZR engine. Below are extended details about the all-aluminum MZR engine: Lightweight aluminum alloy pistons: The lightweight aluminum alloy material can adapt to the temperature conditions of lean mixture combustion. The piston section undergoes acid-resistant aluminum treatment to enhance wear resistance. Additionally, a graphite coating is applied to the piston friction areas to improve abrasion resistance and reduce operational noise. Box-type balancer shaft: This achieves precise transmission coordination through meshing with the engine crankshaft, optimally reducing engine vibration during transmission, ensuring smooth operation and noise reduction. Integrated crankshaft main bearing cap: The integrated crankshaft installation bearing shells ideally ensure the coaxiality of the engine crankshaft and installation precision, reducing engine operational noise and extending the service life of the crankshaft and bearing shells, thereby prolonging the engine overhaul cycle. The lightweight aluminum alloy engine significantly reduces weight, enhancing vehicle acceleration performance and markedly improving fuel economy.
