The KAIST Engine laboratory is focused on researching the combustion and emissions for changing the FIE(Fuel Injection Equipment) and the engine component. For instance, we studied difference between the solenoid type and the piezo-actuated injectors. Also, we research the effect the combustion bowl shape on combustion and emission in diesel engine.
Background: The diesel engine has the advantage of the fuel economy and CO2 emission. The diesel engine only adopted at a heavy duty trucks. But, recently it applied to light duty truck and automobile. According to a report released by J.D. Power-LMC Automotive Services a couple months ago, the sale of dieselpowered light vehicles is expected to increase globally from 12.5 million this year to 27 million by 2015, “with 60% of the growth coming from outside Europe.” A good portion of that increase is expected from North America, which the report predicts will see light-duty trucks and automobiles comprising about 16% of sales within the next 12 years, quite a large jump from the 4.5% J.D. Power says North America saw last year. The dramatic rise in diesel-powered automobiles being bought in Europe has much to due with how the engineers employed have worked to make the engines perform to the advantage of both consumer and environment. The technologies with HSDI(High Speed Direct Injection) Diesel Engines will continue to evolve no matter where the diesel is being driven.
