The emergence of turbocharging technology has a history of over 100 years now, while mechanical turbocharging is even earlier. Early mechanical turbocharging technology was mainly used for mine ventilation and industrial boiler intake. Turbocharging was a technology used in airplanes during World War I, and it was later that these two technologies slowly entered the automotive industry.
The earliest turbocharging technology was first used in airplanes, and engineers discovered the charm of turbocharging. After continuous experimentation, in 1962, General Motors incorporated an Oldsmobile Jetfire into a turbocharging system, becoming the world’s first car to adopt turbocharging technology.
In the era when turbocharging was first used, technological development was not yet mature. In cars equipped with turbocharging, intermittent power often appeared, which is now known as “turbo lag” because the engine speed drops relatively quickly when the accelerator pedal is released. When fuel is continued, the turbine rotates again to drive the turbocharger impeller, completing this series of actions will take some time, Of course, this time is very short, so in order to solve this problem, in the 1980s and 1990s racing competitions, a biased ignition device was used to solve the problem of turbine lag.
By the late 1990s, China had introduced a batch of Volkswagen Pass at 1.8T. In 2002, with the Audi A6 1.8T, turbocharging technology officially entered the Chinese market and was favored by consumers. At the same time, the problem of turbine lag has also become the primary challenge for engineers in major automotive companies. Unlike naturally aspirated engines, turbocharged engines require a reduction in compression ratio and an increase in turbocharging value to reduce turbo lag, which is also a measure taken by major automakers today. Moreover, current technology is relatively mature and turbo lag is not significant.
