How about Roewe rx5 engine? What kind of engine does Roewe rx5 use?

Sai C Roewe RX5 is equipped with its 1.5T and 2.0T engines. Both engines adopt mainstream engine technologies such as aluminum alloy cylinder block, direct injection technology in fuel cylinder and variable timing system of intake and exhaust. 2.0TGI turbocharged engine with maximum power 162 kW /5000-5300rpm and maximum torque of 350N middot；; M /2500-4000 rpm. 1.5T engine 169 horsepower, with a peak torque of 250n·middot· m.

1.5T engine

Roewe rx 5 1.5T engine, peak torque 169 horsepower, 250N middot meters, with the support of 7-speed dual-clutch gearbox, the cost performance is simply higher than the sky. In small displacement engines, there are not many direct injection technologies. Putting the spark plug and the fuel nozzle at the top of the combustion chamber and the center of the four valves at the same time puts forward higher requirements for the design of the cylinder head, which is more difficult than the manufacture of the side nozzle.

The intake valve and safety valve of the turbocharging system of 1.5T 15E4E engine are integrated on the turbocompressor and are electrically controlled. When the driver suddenly receives oil, the valve will open and communicate with the supercharged side and the non-supercharged side of the turbocharger compressor, thus reducing the impact of high-pressure intake air flow on the throttle valve with a sudden decrease in opening, and at the same time preventing the turbine speed from greatly decreasing, affecting the engine performance, and speeding up again.

Due to the background of cooperative development, the 1.5T 15E4E engine on Roewe R X5 is the same as the general 1.5T engine in hardware and power output parameters. This 1.5T 15E4E engine is equipped with many mainstream technologies, such as turbocharging, direct injection in cylinder, variable valve timing of intake and exhaust, etc. Compared with the side nozzle, the middle nozzle technology of this engine has better performance in gasoline atomization effect and emission level, and there is still more room for technical upgrading in the future.

2.0T engine

Unlike the 1.5T engine, the 2.0T engine was independently designed and developed by SAIC. The engine adopts some mainstream technologies at present, such as in-cylinder direct injection, turbocharging, dual variable timing technology of intake and exhaust, disconnectable water pump, all-aluminum material and so on.

Although this 2.0T engine is independently developed by SAIC, based on the technical cooperation background with General Motors, the technical reserve of this engine is not only in the leading position among its own brand models, but also the engine technology invested by some joint venture brand manufacturers is inferior, such as electronically controlled water pump, electronic thermostat, integrated design and overhead fuel rail.
