General Motors today revealed its new-generation Ecotec 1.0T and 1.3T dual-injection engines that are being launched in China. The turbocharged engines were developed as a global architecture with the support of GM’s worldwide manufacturing and supply chain networks. They will power Buick and Chevrolet models built and sold in the domestic market starting later this year.

“GM is integrating our unmatched global resources with our local capabilities to offer reliable, durable and efficient propulsion systems,” said Michael Carman, GM China vice-president of Global Propulsion Systems. “These new engines will offer a great ownership and driving experience to our customers across China.”

While the 1.0T engine generates maximum power of 92 kW/170 Nm, the 1.3T engine develops 120 kW/230 Nm. GM claims fuel economy has been improved by up to 10 percent. Representing a new architecture, the new-generation engines incorporate a series of cutting-edge driveline technologies. They are the first turbocharged engines to apply dual port injection, which optimises combustion.

The engines have a compact aluminium structure and redesigned combustion chamber, further enhancing efficiency. Twelve core technologies have been adopted to significantly reduce structural noise and vibration. The innovative application of intelligent mechatronics supports precise control, green operation and high power.

GM says its durability test saw 367 prototypes being put through nearly 6 million kilometres of testing in different conditions, including high altitude, high temperature, extreme cold, high humidity and corrosive environments, and on varying road surfaces.
