What is the compression ratio of the Geely Emgrand GS?
2 Answers
Geely Emgrand GS has a compression ratio of around 8. Introduction to compression ratio: To illustrate the technical parameters of an engine, one can roughly use the magnitude of power and torque as indicators. However, there are many factors that influence the output of power and torque, with one important factor being the engine's compression ratio. The compression ratio indicates the degree to which the gas in the cylinder is compressed when the piston moves from the bottom dead center to the top dead center. The importance of compression ratio: The compression ratio is a very important concept in engines, representing the degree of gas compression. It is the ratio of the volume of gas before compression to the volume after compression.
I drive a Geely Emgrand GS 1.4T version. As an ordinary car owner, I specifically researched the compression ratio when choosing a car, which is around 9.5:1. This value determines the engine's efficiency. A higher compression ratio allows for more complete fuel combustion, so my car has sufficient power and is fuel-efficient in urban driving, averaging around 7 liters per 100 kilometers. However, too high a compression ratio may cause knocking, so I insist on using 95-octane gasoline to avoid engine damage, and I feel that proper maintenance makes the drive smoother. During daily commuting, this design ensures quick acceleration response, making it effortless to start at traffic lights. Additionally, the compression ratio is linked to emissions, making it more environmentally friendly and saving on car taxes. I recommend new owners to regularly check the ignition system to maintain stable compression and extend the car's lifespan. Overall, the 9.5:1 ratio is quite suitable for daily family use, and buying the Emgrand GS was a wise choice.
