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. "Under the battle and the winner of the temple, it is worth more." In this context, as a listed company that developed small gasoline engines earlier in China, Dongan Power conforms to the development law of the automobile industry, looks forward to the development trend of automobile power, and concentrates on developing small displacement. The high-power, high-torque turbocharged gasoline engine is launched with the DAM12T supercharged engine. This series of models fully applies mainstream technologies such as intake and exhaust dual VVT, variable displacement oil pump, high-efficiency lean burn, electronic vacuum pump, etc., with (net) power and liter (net) torque of 75kW and 150N·m respectively (see DAM12T engine external characteristic curve), the engine power performance has reached the leading level in the same industry.

Applying cutting-edge technology, small displacement, big power
Through the abundant technical reserves and forward-looking layout of Dongan Power, DAM12T supercharged engine and supercharged direct injection series are developed and collinearly produced on the same platform. It has the characteristics of mute and precision design and light weight, with maturity and consistency. Durable features, based on a new and highly efficient modular design, with leading-edge technology such as continuously variable timing valve, cylinder head and exhaust manifold integration design, while maintaining high efficiency while achieving a wide torque range, also taking into account the high The balance between performance and low fuel consumption has reached a high degree of alignment with the current overall trend of the domestic automotive market and policies.
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 vibration-damping balance shaft arrangement solves the problem of the noise, vibration and smoothness (NVH) performance defects of the conventional three-cylinder machine. The application of all-aluminum cylinders and aluminum-spray cylinder sleeves reduces the weight of the whole machine while improving the bonding rate and thermal conductivity. The cylinder head is integrated with the exhaust manifold to shorten the warm-up time and effectively reduce fuel consumption and emissions. Wheel tension and NVH performance are enhanced with automatic tensioners and elastic V-ribbed belts. In addition, the selection of many technologies such as dual mass flywheel (DMF), idle start and stop technology (STT), hollow sodium-filled exhaust valve, honeycomb valve spring, mechanical vacuum pump and surface diamond-like (DLC) coating has greatly improved. The overall performance and competitiveness of the DAM12T engine. 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 development team has painstakingly studied “fuel savingâ€. The design and development engineers have 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 turbocharger is the result of various factors such as industry regulations, automobile enterprise development and consumer demand. At the regulatory level, the “Fourth Phase Standard for Passenger Vehicle Fuel Consumption†will be implemented from January 1, 2016. The average fuel consumption limit for passenger vehicles in 2020 is 5 liters/100 kilometers. The policy red line has been delineated, and auto companies must respond technically to reducing energy consumption. In the long run, the development of new energy vehicles is an important strategy for the development of the automotive industry. In the short to medium term, the application of more energy efficient turbocharging technology is the common choice of most automotive power companies. At the consumption level, from October 1, 2015, the state has implemented a policy of halving the purchase tax for passenger cars of 1.6L and below. Small-displacement models are highly regarded by the consumer market; after the implementation of the policy, small-displacement turbocharged models The sales ratio has been greatly improved. Better power performance and fuel economy under the same displacement are 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, the DAM12T series supercharged engine has received much attention. At present, some auto companies have shown strong interest in the DAM12T series engines. Several car engine matching projects have been officially established, and the initial confirmation of the car engine matching program has been completed.
In-depth market research to boost car power upgrades
In order to achieve the average fuel consumption limit for domestic passenger cars in 2020, the fourth-stage standard will further tighten the bicycle fuel consumption limit and the enterprise average target value, and simultaneously evaluate bicycles and enterprises. 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, in response to the national automobile industry laws and regulations, Dongan Power has fully popularized low-cost fuel-saving technologies such as VVT+EGR, dual VVT and three-cylinder layouts from the initial comprehensive intake. The development and application of exhaust gas turbocharging technology and extended-range engine technology, and nowadays in-cylinder direct injection and future hybrid long-term planning, while meeting the fuel consumption regulations of different stages, Dongan Power from the perspective of vehicle customers, Use relatively low-cost engine product solutions to improve vehicle competitiveness, respond to automotive industry policies, implement the concept of energy-saving, low-carbon and environmentally-friendly vehicles, and improve the competitiveness of engine products. This platform is the company's first supercharged/supercharged direct-injector-type public platform, which highlights the high-performance, low-cost and cost-effective advantages; it is the only one in China that is suitable for FF, FR and MR layouts. Fill the blank of the small-displacement supercharger model of the independent engine company. Obviously, the domestically developed DAM12T series models represented by Dongan Power have the “small displacement, high power and high torque†as the most distinctive label in the current turbocharged era, which deeply caters to consumers’ strong power and The dual demand for low energy consumption 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.
In the next five years, turbocharged engines will account for more than 35% of the market, and competition among auto companies will focus on small-displacement turbocharged engines; how to get more power with smaller displacements It will be a common problem faced by major auto companies.
