What is the compression ratio of the Teana?
2 Answers
The compression ratio of the Teana is 8:1. It is equipped with a brushless drive motor, and the new engine achieves continuous stepless variation of the compression ratio from 14:1 to 8:1. Moreover, it only takes 1.2 seconds for the compression ratio to drop from the maximum to the minimum. Introduction to compression ratio: To describe the technical parameters of an engine, it can generally be indicated by the size of power and torque. However, there are many factors that affect the output of power and torque, one of which is the compression ratio of the engine. Importance of compression ratio: Compression ratio is a very important concept in engines. It indicates the degree of gas compression and is the ratio of the volume before gas compression to the volume after gas compression.
I've been driving a Nissan Teana with a compression ratio around 11.2:1, a figure I've checked multiple times in the manual. The compression ratio refers to how much the piston compresses the air-fuel mixture in the engine, and 11.2 times indicates quite efficient design, resulting in responsive throttle and an average fuel consumption of just over 7 liters per 100 km, especially worry-free on highways. The high compression ratio also ensures cleaner combustion, reducing carbon deposit issues. For my daily commute, I find the engine quiet with smooth acceleration. This compression ratio requires at least 92-octane fuel—never skimp on quality fuel to avoid occasional knocking and reduced lifespan. Overall, the Teana is easy to maintain with a moderate compression ratio, so no need to worry about engine knocking.
