YC6M 10L heavy-duty engine is Yuchai's leading products. YC6K, is more than 12 liters of heavy Yuchai engines. YC6MK, by definition, it is Yuchai introduced this year a range between 6M and 6K of new products. The main performance development platform based on YC6M, but was higher than the YC6M platform. Compared YC6M, YC6MK displacement from 9.8L to upgrade 10.3L, power range covering 300-420 hp (YC6M cover the 280-375 hp engine power), have greatly enriched in the heavy-duty engine market Yuchai strains.

    Configuration more robust performance across the board upgrade

    According Yuchai technical personnel, YC6MK displacement of 9.8L from YC6M to 10.3L, but in appearance, YC6MK YC6M basically the same size and weight of the engine is also lighter than 11 liters; YC6MK PTO output torque of the engine by the 500N.m to 800N.m, increased by 60%.

    The engine cylinder head, water pump, pulley system and a series of performance upgrades. YC6MK engine water pump improvements, energy-saving version of the heavy machinery and YC6M same as the ordinary high water pumps water pump upgrade, reduce weight, reduce the shaft power. YC6MK the engine cylinder head from the previous "one cylinder a cover" to "whole head", so the design, make the waterway more smooth cycle, the engine cooling capacity; and its rigid, high strength, vibration, reduce noise , which will help control emissions and improve reliability. In order to better promote energy between the components of the engine transmission, YC6MK the pulley system also made a corresponding improvement. It replaced the original water pump fan pump fan coaxial separation, this way, increase the fan shaft, pumps, motors and other components of reliability.

    User-friendly design of energy saving and safer

    Evaluation of engine performance is an important indicator of quality energy saving and operational safety, it is reported, YC6MK heavy machinery, four-valve technology, a substantial increase in the engine's intake and exhaust flow area, improve the efficiency of the engine's intake and exhaust while reducing the intake and exhaust noise. The injector in the home technology, making more uniform atomization of fuel, burning more fully to achieve the purpose of energy saving engine.

    "In order to improve active safety, YC6MK heavy machine using an improved cylinder braking system (VVEB)." Yuchai technician said that the use of the braking system YC6MK to 55% of the vehicle braking force (the coefficient than similar products in Europe and 10% higher low-speed braking force). "This improvement will allow the driver is driving under the long slope of the time, less or even no foot brakes, effective braking force to prevent decay, brake failure, the direction of deviation and so on rainy days."

    In addition, YC6MK for in the desert, mines and other dusty work site vehicles, in particular, the configuration of the desert air filter. The air filter by a cyclone pre-filter, two crude oil bath type filter and fine filter paper three filters, can increase to 99.94% filtration effect.

    In order to improve fuel efficiency, Yuchai YC6MK heavy machine also worry with a smart filter. The province heart can intelligently filter fuel filter in the water and impurities, improved startup performance, while improving the starter, fuel pump, fuel injector reliability. YC6MK Yuchai Heavy Machinery and technical personnel through specially designed, even in the northern provinces of the ultra-low temperature environment under normal operation.
