Recently, high school classmates organized kicks and unified equipment to say that they would like to buy a nostalgic leap. Let the girls who saw the white leap shoes on the subway be more fresh and natural, and feel that this is a 'clear stream' in the city of paper fans. Leap in the status of shoes, like the status of Jiang Xiaobai's white liquor, not worshipping gold, not B, quite literary style. The position of the three-cylinder machine in the engine, like, leap to the shoes, Jiang Xiaobai Liquor, watching the greasy large displacement engine, wake up all night is a three-cylinder machine, the three-cylinder machine has a clear fresh feeling, a little meaning!
Small displacement is the future direction of the traditional power of the car. At present, the development of small displacement engines by mainstream enterprises is almost aimed at the three-cylinder machine.
In the 2018 International Engine Awards, three three-cylinder machines entered the top nine of the list. In the field of small displacement engines, all the best awards of the year were taken over by the three-cylinder machine.
In this trend, SAIC GM Buick brand launched its home mid-size sedan with a new generation of Ecotec dual-jet turbocharged engine with its unique vision, and seized the market opportunity with strength.
Three-cylinder machine leads the trend
In the past two years, under the trend of energy saving and emission reduction, many brands such as Honda, BMW and Ford have equipped their cars with three-cylinder engines. Speaking of the three-cylinder engine, Ford's 1.0-liter Ecoboost three-cylinder engine is a classic representative. Ford's Fox, Wings and other vehicles are equipped with this three-cylinder engine. It can be said that this engine began to change people's impression of the ordinary three-cylinder machine, but also opened the three-cylinder machine power.
In 2014, Volkswagen launched the 1.0T three-cylinder turbocharged engine. In 2016, BMW replaced the four-cylinder with a 1.5T three-cylinder turbocharged engine. The new BMW X1 also reloaded this power. The Buick brand is In October 2017, the new generation of three-cylinder small-displacement intelligent engines, Yinglang, Yuelang and GL6, were launched. The Volvo XC40 will also be equipped with a 1.5T three-cylinder engine.
When it comes to the three-cylinder engine, many people have a stereotype that it is weak in power, strong in jitter, loud in noise, and poor in smoothness. It is a three-day look at the three-cylinder machine, such as Buick’s three-cylinder machine, by SAIC General Motors. Integrate global superior resources and develop based on new architecture.
It has high intelligent electronic control, high efficiency integration, high-tech mute, high reliability and durability, performance indicators fully surpass the previous generation products, and break through the bottleneck, noise and other bottlenecks that restrict the development of three-cylinder machine; equipped with 6-speed manual transmission, 6-speed automatic transmission, 6-speed wet dual-clutch automatic transmission and other new generation gearboxes that support intelligent start-stop technology, combining high-efficiency power output with fuel-saving and environmental protection, combined with superior quietness, reliability, durability and low maintenance Cost, comprehensive display of 'more performance, more energy-efficient, more environmentally friendly, smarter' product leadership, bringing consumers a new driving and car experience.
Among them, the new generation 1.3TEcotec dual-jet turbocharged engine can output the maximum rated power of 120kW/5500rpm, the maximum torque is 230Nm/1800-4400rpm, and the power is up to 92.3kW/L. Compared with the previous generation 1.4T engine, 1.3T engine weight Reduced 25 kg, power increased by 15%, fuel consumption decreased by 5%, even on the Buick medium-sized MPVGL6, the acceleration of 100 km is only about 10 seconds.
The other 1.0T engine has a maximum power of 92kW, and can continuously output 90% peak torque at 1500rpm-5200rpm. It can stably output 170Nm maximum torque at 2000rpm, while the previous 1.5L engine needs 4000Hz to reach 141Nm maximum torque; and 1.0T The engine has a weight loss of 24 kg compared to the previous generation 1.5L engine, fuel economy has increased by 10%, and fuel consumption has decreased by 0.5L (6-speed manual) and 0.8L (6-speed DCG dual clutch).
Leading technology industry
In the domestic automotive industry, SAIC GM's manufacturing capabilities are second to none. The new generation of 1.3T/1.0TEcotec dual-jet turbocharged engine is located in the engine plant of SAIC-GM's Wuhan base and Dongyue base.
The two engine plants are also the display windows for SAIC GM's intelligent manufacturing. They not only have world-class, domestically leading facility configurations and processes, but also gain the essence of intelligent manufacturing in digital, automation and big data applications.
Relying on SAIC GM's benchmark-level intelligent manufacturing strength, the new-generation Ecotec dual-jet turbocharged engine is produced in a fully digitally designed factory, and adopts an innovative model of digital development simultaneously with products and processes. The first application of Siemens PLM/PDM platform products Comprehensive digital 3D design, digital virtual analysis and simulation, integrated management of product development and process development.
The intelligent manufacturing strength of SAIC GM's benchmarking industry has laid a solid foundation for the high quality and high standards of Buick's new generation of mid-level family cars. Based on strong system strength, Ecotec's small-displacement intelligent engine series will continue to enrich the spectrum. To meet the increasing demand for small displacement high performance engines in the Chinese market, leading the industry and market trends.
