At present, turbocharging technology has been deeply rooted in people's minds, and more and more passenger cars have begun to significantly reduce engine displacement in order to meet increasingly stringent fuel consumption and emission regulations. If you don’t fight and the temple wins, you have to count more. Under this background, as a listed company that developed small gasoline engines earlier in China, Dongan Power Co., Ltd. follows the development law of the automobile industry, and looks forward to the development trend of automobile power, and concentrates on the development of small displacement, high power and high torque turbocharged gasoline engines. Introduced the DAM12T supercharged series engine, which is fully applied to mainstream technologies such as intake and exhaust dual VVT, variable displacement oil pump, high-efficiency lean burn, electronic Vacuum Pump, etc., and the lift (net) power and the lift (net) torque are respectively achieved. 75kW and 150N·m (see DAM12T engine external characteristic curve), the engine power performance has reached the same industry leading level. Applying cutting-edge technology, small displacement, big power From the perspective of technology research and development, through the technical reserves and forward-looking layout of Dongan Power, the DAM12T supercharged engine and the supercharged direct injection series are developed on the same platform and produced in line, with mute and precision design and lightweight features. With its maturity, consistency and durability, it is based on a new and highly efficient modular design with leading-edge technologies such as continuously variable timing Valve, cylinder head and exhaust manifold integration design, while maintaining high efficiency while achieving a wide range of The torque range also balances the balance between high performance and low fuel consumption, and has reached a high level of alignment with the current domestic automotive market and policy trends. In addition to the application of exhaust gas turbocharging technology (Turbo), the DAM12T series engines also use a number of cutting-edge technologies. The combination of the three-cylinder structure and the rubber shock-absorbing balance shaft arrangement solves the problem of the noise, vibration and unevenness (NVH) performance defects of the traditional three-cylinder machine, and the aluminum cylinder and the aluminum spray cylinder sleeve reduce the weight of the whole machine and improve at the same time. Combination rate and thermal conductivity; cylinder head integrated exhaust manifold to shorten warm-up time, effectively reduce fuel consumption and emissions; use automatic tensioner and elastic multi-ribbed belt to enhance wheel reliability and NVH performance; (DMF), Idle Start and Stop Technology (STT), hollow sodium-filled exhaust valves, honeycomb valve springs, mechanical vacuum pumps and surface diamond-like (DLC) coatings have greatly improved the overall performance of the DAM12T engine. And competitive. The project team painstakingly studied "fuel-saving", whether it is a lightweight aluminum cylinder design, a variable displacement electronically controlled oil pump that greatly reduces friction, or a DLC coating that reduces frictional resistance. The design and development engineer has achieved the most competitive power and fuel consumption performance for each of the detailed processes involving power and fuel consumption. Automotive regulations drive low fuel consumption and practice energy saving The formation of the trend of domestic automobile engine turbocharging is the result of various factors such as industry regulations, car enterprise development and consumer demand. At the regulatory level, according to the “Fourth Stage Standard for Passenger Vehicle Fuel Consumption†implemented on January 1, 2016, the average fuel consumption limit for passenger vehicles by 2020 is 5 liters/100 kilometers. The policy red line has been delineated, and the car factory must respond technically to reduce energy consumption. In the long run, the development of new energy vehicles is a strategic deployment for the development of the automotive industry; in the medium and long term, the application of more energy efficient turbocharging technology It has become the common choice for the development of most automotive power companies. At the consumption level, since October 1, 2015, the state has implemented a policy of halving the purchase tax of passenger cars of 1.6L and below. The small-displacement models have been highly praised by the consumer market, and the small-displacement turbines have increased since the implementation of the policy. The proportion of sales of pressure models has been greatly improved. Better power performance and fuel economy under the same displacement are of course more favored by users, which is also a technical feature of turbocharged models. It is the long-term technological development and accumulation that enables small-displacement turbocharged models to have a broad market base. With superior power performance and good fuel economy, DAM12T series supercharged engines have attracted much attention from the market. At present, some car companies have shown strong interest in DAM12T series engines. Several car matching projects have been officially established and completed. Initial confirmation of the vehicle matching program. In-depth market research and planning automotive power upgrades In order to achieve the goal of “Planning†for the average fuel consumption of domestic passenger vehicles to fall to 5.0L/100km in 2020, the fourth-stage standard will further tighten the bicycle fuel consumption limit and the enterprise average target value, simultaneously for bicycles and enterprises. Assessment. In the face of the most stringent fuel consumption regulations in history, the lightweight, compact design of the engine and the application of energy-efficient and advanced technology have become the preferred solution to solve the fuel consumption problem of the whole vehicle. In order to meet the needs of domestic economic passenger car powertrain products, the national automobile industry laws and regulations should be met. Dongan Power has comprehensive low-cost fuel-saving technologies such as comprehensive friction reduction, intake VVT+EGR, double VVT ​​and three-cylinder arrangement. Popularization, from the development and application of exhaust gas turbocharging technology, extended-range engine technology, to today's in-cylinder direct injection and future hybrid long-term planning, while meeting the fuel consumption regulations of different stages, Dongan Power from the entire vehicle customer From the perspective of the use of relatively low cost engine product solutions to improve vehicle competitiveness, in response to automotive industry policies, the implementation of energy-saving low-carbon environmentally friendly car concept, improve the competitiveness of engine products market. The development of the supercharged project is the first. It is the company's first supercharged/supercharged direct-injector-type public platform, which highlights the high-performance, low-cost and cost-effective advantages. The uniqueness of the excavation is the only one in China that is suitable for both FF and FR. The MR-arranged engine fills the blank of the small-displacement supercharger type of the engine company that exists independently. Obviously, the domestically developed DAM12T series models represented by Dongan Power, "small displacement, high power, high torque" as the most distinctive label of the current turbocharged era, deeply cater to consumers' strong power and low The dual demand for energy efficiency is harmonized with the country's increasingly stringent fuel consumption standards for passenger cars. The forward-looking development of the Dongan Power DAM12T series engine took the lead and took the lead in the turbocharged market. It is predicted that the market share of turbocharged engines will exceed 35% in the next five years. The competition between car companies will be concentrated on small-displacement turbocharged engines. How to use smaller displacements to get more power, less energy consumption and emissions will be the common needs of major car companies. Right question.
