1 and hongqi 1.5T engines

The third-generation series engine independently developed by China FAW integrates intelligent thermal management, Miller cycle, electronically controlled piston cooling nozzle and other technologies. The official gives a high compression ratio of 1 1.5: 1. With the high compression ratio of 1 1.5: 1 and the support of other engine technologies, the combustion thermal efficiency of this engine has reached 39.06%, which is close to the number one Toyota engine in the industry, with an average fuel consumption of 8.0L/ 100km and good economy.

2. Changan 1.5T NE engine

This 1.5T engine also features an integrated exhaust manifold, twin-turbine electronically controlled turbocharging, high-pressure direct injection, fully variable displacement oil pump, independently controllable PCJ, parallel cooling and external water-cooled intercooler. Under the joint action of these technologies, its maximum output power and torque reach 132kW and 300Nm respectively. This engine is mainly used in changan uni-t.

3. BYD Xiaoyun 1.5Ti engine

This Xiaoyun 1.5Ti high-power engine integrates many technologies, such as rolling intake system, dual-channel turbocharger, 350 bar precise fuel injection, friction reduction and all-aluminum lightweight. The maximum output power of this engine is 136kW, and the peak torque is 288n m. At present, this car is mainly used in BYD Song PLUS, with a 7-speed dual-clutch gearbox and a comprehensive fuel consumption of about 7.0L/ 100km.

4. Dongfang 1.5T engine

This engine combines many technologies such as electronically controlled exhaust gas turbocharging, 350 bar in-cylinder direct injection, high-pressure EGR, central intake and exhaust VVT, integrated exhaust manifold and so on. Through this series of technical blessings, high thermal efficiency, high power, high responsiveness and ultra-low emissions can be achieved. The maximum output power of the power version is 150kW, and the peak torque is 320n·m；; ; The thermal efficiency of the high-efficiency version reaches 4 1.07%.

5. Buick Ecotec 2.0T engine

Buick's eighth generation Ecotec 2.0T variable-cylinder turbocharged engine is developed based on the "single-cylinder optimal concept" and a brand-new modular architecture. It has three modes of four-cylinder high performance, economy and two-cylinder economy, which meet the national six emission standards.

In addition to the mainstream variable valve timing system, it also provides an intake and exhaust valve lift control system, which can control the intake and exhaust valves in sections to further protect the vehicle's power performance and fuel economy.
