The lightweight powertrain ( Engine + Transmission + Axle ) focuses on the concept of lightweight, while launching a 9L engine to replace the D10 engine and forming a MAN power supply chain.
China National Heavy Duty Truck Man Technology MC09 Engine
MC09 engine, 8.8 L displacement; 340/360/380 hp; 1600/1700/1800 Nm. Compared to the 340- and 380-horsepower models of the Steyr D10, the MC09 torque is increased by 200 Nm, and the rated power of 380 hp can be achieved from 1600 rpm. This is in full compliance with the mid-to-heavy engine low-speed and high-torque product trends. The MC09 high-efficiency diesel engine adopts a modular lightweight and highly integrated design scheme. The engine's crank linkage mechanism, valve cam mechanism, gear transmission mechanism, dual-stage balancing mechanism, and accessory wheel train mechanism are fully satisfied with the Mantech engine. Verification of release conditions, through the high reliability assessment standards of the core components of Mantech; MC09 and MC11/13 share the Manco production line, with the exception of cylinders, cylinder heads, crankshafts, balancing mechanisms, cylinder head covers and oil pans, etc. Parts and assemblies are completely interchangeable, and the MC09 and MC11 engine parts are 95% common.
MC09 machine manufactures the casting, forging, technology, materials and assembly of Synchronous engine technology. It adopts the high assembly precision, cleanliness and factory inspection procedures of German Mann quality. The dynamics, economy, reliability, comfort and other qualities are at rest. Leading domestic and international advanced level.
B10 life of 1.5 million kilometers; MC09 high-strength vermicular graphite cast iron cylinder head, non-quenched and tempered steel crankshaft connecting rod; main bearing cap and connecting rod large head cover disintegration process; split cooling water jacket and high sealing structure; The peak burst pressure of the carrier exceeds 220 bar. The rigidity of the whole machine is greatly improved, and the torsional vibration natural frequency is not generated in the speed range of the moving mechanism. The original parts are supplied by Mantech.
MC09 adopts a modular, lightweight and integrated solution. The number of parts and components of the entire machine is reduced by 30% compared with the same model of the market, and the weight of the whole machine is about 100 kilograms. Thanks to the integrated application of the reduced-cylinder technology and energy-saving accessories, the loss of friction work is reduced by 15%, which significantly increases the mechanical efficiency of the engine. It is reflected in the fuel economy and brings a fuel consumption reduction of no less than 3%.
The first insurance is not needed during the use of the aircraft, and the longest oil change period for road vehicles is up to 100,000 kilometers.
For long-distance transport commercial vehicles, such as tractors and trucks, it is necessary to reduce the engine speed and operate in a low-speed economic zone. In order to ensure the climbing and maneuverability of the entire vehicle, the low-speed torque curve needs to be adapted, and the MC09 engine exhibits a significant advantage of low speed and high torque.
The MC09 has a maximum power of 380 hp (1600rpm-1900rpm), a maximum torque of 1800Nm (1100-1400rpm), an increase in power of 32kW and a rise in torque of more than 200Nm. In the domestic engine with the same displacement, the peak torque is the highest, and the torque reserve rate is the highest. More than 30%; MC09 has the lowest fuel consumption of 187g/kWh in external features, and the lowest fuel consumption of all features is less than 185g/kWh, leading the domestic competition models, achieving low speed, high torque, and ultra-low fuel consumption. Effective combination; MC09 uses ecb mode of exhaust valve in the cylinder, the maximum power is 220Kw, which reaches 80% of the output power; the two-speed output torque (650Nm and 870Nm) after PTO is the same as that of MC11/13; in plateau capacity, MC09 has an altitude adaptation capability of 5000 meters above sea level. The maximum power loss of the main type of plateau is less than 20%. High-pressure injection, four-valve overhead cam and high-efficiency turbocharger are used to precisely control the combustion process in the cylinder. The highest thermal efficiency of the external characteristic is 45.7%, and the highest characteristic combustion thermal efficiency reaches 47%. MC09/11/13 is the current domestic heavy-duty The typical representative of the highest thermal efficiency engine.
MC09 In-cylinder High-Efficiency Combustion and Calibration Control Considering both fuel consumption and bare-metal emission, urea and fuel consumption ratio is less than 5% (National Five); the third-generation electronically controlled air-assisted SCR post-processing system is used to achieve stable implementation of China Five and Beijing Five Emission standards, and can reach the Euro 6 emission level through an upgraded post-processing system.
MC09 adopts double-stage high-efficiency balancing mechanism. The unbalanced moment elimination rate of the moving mechanism reaches 100%. The vibration test results of the whole machine reach the same level as MC11/13. The high-precision modified helical gear transmission system balances the quality of the assembly. Reduced by more than 50% compared to competing products. With the optimized suspension scheme, the vibration isolation rate of the front and rear mounting suspensions of the MC09 on the T6 vehicle is more than 85%. The vibration test and subjective evaluation of typical positions such as the steering wheel, seat, and instrument panel in the cab are all the same as in the 7-platform vehicle. Level. Adopt low-intensity high-rigidity and low-inertia crank connecting rod movement mechanism, rear-mounted timing gear transmission, overhead camshaft, reduced cylinder technology, energy-saving auxiliary system, the whole machine friction power consumption is greatly reduced by 15%; surface cover A large number of heat-resistant composite materials and lightweight materials are used. The average sound pressure level of one meter is about 96 decibels. The vehicle equipped with six platforms meets the second phase of vehicle acceleration noise regulations in the EU and China.
The aircraft will be used for China National Heavy Duty Truck 6-platform road tractors, trucks, dump trucks, urban special vehicles, cement mixers, 12-meter passenger cars; construction machinery off-road engines.
The main reducer of MCY11 Bridge is of reasonable structure and good support rigidity. The main reducer bevel gear adopts Oricon tooth system and long gear life. The reinforced stamped and welded axle housing has reasonable structure, and the high-performance axle housing material developed independently is of high strength. Matching Drum Brake, good brake safety, high comfort, easy maintenance; wheel bearing selection without adjustment bearing unit, simple assembly, high service life, easy maintenance; increase oil filter, ensure the cleanliness of gear oil, improve gear, The bearing life is mainly applicable to road vehicles.
Precipitated Calcium Carbonate

It can also be used as a medium seeding agent for industrial waste water, a antacid for stomach and duodenal ulcers, a detoxifying agent for acidosis, a SOâ‚‚ eliminating agent in SOâ‚‚-containing exhaust gas, a dairy cattle feed additive and an anti-sticking agent for oil felt . It can also be used as a raw material for tooth powder, toothpaste and other cosmetics.
Usually used as a filler, widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc., as a filler to increase products The volume is reduced, and the production cost is reduced.
Light Calcium Carbonate is made of limestone, and can be used in daily chemical products such as tooth powder, toothpaste, cosmetics, etc. It can also be used in organic synthesis, metallurgy, glass and asbestos production.
The particle size of light calcium is smaller than that of Heavy Calcium Carbonate, the oil absorption is larger than that of heavy calcium carbonate, and the price is higher than that of heavy calcium carbonate. They are all commonly used fillers in latex paint, and they are best used together. Light calcium is better in terms of sedimentation, but its oil absorption is greater than that of heavy calcium, and the price is generally more expensive than heavy calcium. Although it is not as stable as heavy calcium, it is stable. Even for exterior wall paint, its application amount is also very large. of.
