While the sales volume of micro-customers has increased significantly, the powertrain has become the key to micro-subsequent technology upgrades. Major micro and micro-enterprise companies have gradually launched micro-customer products equipped with autonomous engines. The renewal of engine technology greatly satisfies the demand of consumers for the micro motive power, so as to realize high-speed and heavy-load products. It can be said that the technical upgrading of micro-cam products started from the engine. SAIC-GM-Wuling B-Series Engine SAIC-GM-Wuling B series engines are characterized by low cost, low fuel consumption and high power. The maximum power is 63kW/6000rpm and the maximum torque is 108N?m/4000rpm. This series of engines uses an in-line four-cylinder design with two intake valves and two exhaust valves per cylinder. A total of 16 valve design, so that the engine in the valve design to reach the level of advanced 4-cylinder cars. At the same time, DOHC (Dual Overhead Camshaft) type structure is adopted, and the valve is operated with a direct-drive DOHC structure, which not only reduces friction but also achieves high-speed power tracking performance. At the same time, it simplifies the structure, reduces the number of parts, and is effective. Compress the weight and volume of the engine. In addition, the B series engine has extended its service life by adopting a camshaft drive with excellent durability and chain drive. Each B-Series engine is equipped with a petrol nozzle on each cylinder, so as to achieve independent supply of oil to each cylinder, to avoid the disadvantages of single-point injection "one-size-fits-all". The injection volume of each cylinder is controlled and adjusted by the computer, so to each The amount and time of the injection of oil and gas by the cylinders should be more precise, thereby improving the combustion efficiency of the engine. It is understood that the SAIC-GM-Wuling B series engine integrates SAIC and GM's superior resources in engine R&D.

The C Series 1.0L engine is a high-performance, small-displacement engine developed and jointly developed by Changan Automobile and a famous German FEV company. It has 36 patented technologies and has a power of 51kW, which is currently 1.0L. One of the more powerful engines in the market, and Changan has its own intellectual property rights. Power output, durability, and fuel consumption are three important indicators of engine performance. As a new generation of high-performance engine of Chang'an, the C-series engine has excellent performance in all three aspects. Through independent innovation and integration of international technologies, Chang'an Automobile has achieved breakthroughs in engine technology in three areas through optimized design of combustion systems, exhaust systems, and parts and components systems. The first is the increase in power. Due to the constraints of many factors such as R&D technology and manufacturing processes, the current maximum power of most 1.0L small-displacement engines cannot reach 50kW. It can be said that the 50kW power is the watershed of the 1.0L engine. Breakthrough means that Beyond. The Changan C-Series engine adopts DOHC (Dual Overhead Camshaft) and 16-valve technology commonly used in most cars, together with electronic ignition system without distributor, high-performance air-combustion chamber and advanced lightweight piston design, intake and exhaust. Fuller, more complete combustion, greater power output, and less power loss. Based on the use of international advanced technology and sophisticated manufacturing processes, the output power is increased to 51kW, which is approximately 13kW higher than the engine power of the same displacement, and the power is increased by 30%, leading the domestic 1.0L small-displacement engine. In addition, its boost torque is up to 90.9N?m, which also ensures faster vehicle acceleration and stronger bearing capacity. The second is the extension of life. The service life reflects the quality and reliability of the engine. The Changan C series engine has undergone stringent bench test and road test in R&D. The test is conducted in accordance with the German FEV company's standard 800 hours variable condition durability standard. It is far higher than the 300-hour full-load durability standard specified by the national standard. All parts of the engine, such as balanced crankshafts and wavy water jackets, are more durable and reliable. They also meet the stringent FEV reliability and matching test standards. In addition, in field tests, the C-Series engine experienced five consecutive 30,000-kilometer continuous uninterrupted road tests and three high altitude tests at plateaus, high temperatures, and high temperatures. After continuous improvement on the basis of testing, the reliability and life of the C-Series engine have been increased by about 20%, and its long design life of 300,000 kilometers has also provided durability for durability. The third is the reduction of fuel consumption. The Changan C series engine has the characteristics of low speed and large torque. When the engine speed is 2000~3000rpm, the torque can reach 90% of the maximum torque, and the fuel consumption is the lowest in this common speed range. Tests and tests have shown that the constant-speed fuel consumption of the Changan Star II equipped with the C-Series engine is only 4.3L, which is 10% lower than the conventional engine. Excellent fuel economy performance For micro-customers who run more than 30,000 kilometers a year, they can save at least 1,500 yuan per year in fuel consumption. At the same time as the fuel consumption is reduced, the emission level is further increased. According to tests, the models equipped with C-Series engines can meet the national IV emission standards, but also have the potential to upgrade to the country V, which greatly adapts to the current trend of energy conservation and environmental protection.
