 Fuel Efficiency and Prevention of Global Warming |
|
|
 |
Overview |
|
|
|
Higher mass consumption of fossil fuels leads to more CO2 emissions, and this is considered to be the main factor contributing to global warming. This laboratory conducts research on establishing appropriate chassis-dynamometer fuel economy test methods and on fuel consumption assessment methods for heavy-duty vehicles using simulations in order to promote the use of vehicles with good fuel efficiency and low CO2 emissions. Research is also being carried out on methods for estimating the effect of various energy conservation measures, methods to estimate the total amount of greenhouse gases and environmental assessments to evaluate vehicles that have little impact on the environment under a wide range of conditions. |
