          It is recognised around the world that road transport is still responsible for a large proportion of man-made CO2 emissions. Vehicle manufacturers have already reduced pollutant emissions to a tiny fraction of the levels in the 1970s through improvements in fuel combustion and by after-treatment devices, like catalytic converters. Now, increasingly, attention is turning to CO2 emissions. Because burning carbon-based fuel creates CO2, the only ways to reduce it are to use less fuel or to use alternative fuels, which either contain lower levels of carbon or are renewable. With renewable fuels like biofuels, the CO2 generated when driving is offset by absorption of atmospheric CO2, for example during growth of plants used to make biofuels. There is no after treatment, like a catalytic converter, that can be attached to a vehicle to filter out CO2. With global annual sales of new cars continuing to increase and a total of almost one billion cars produced over the past decade, it is clear this remains a growing problem for countries around the world. According to The International Organisation of Motor Vehicle Manufacturers (OICA), significant resources are expended annually developing different CO2-efficient vehicles that run on alternative fuels like bio-diesel, ethanol, hydrogen and natural gas or that use electric or hybrid vehicle technology. There is no one single technology that is the answer.Professor Hsiao-Kang Ma’s team at the National Taiwan University is hoping to develop an alternative to the internal combustion engine with higher thermal efficiency which is more environmentally friendly. Their project is a two-year research and development programme which aims to develop the Eccentric Blade Rotor Rotary Engine as the alternative. Ma explains that aside from renewable fuels, one option that is growing in importance is hybrid engines and that while electric cars have made substantial progress, the battery energy density has set its limits: ‘There is no sign in the near future that the challenges of providing sufficient charging stations and the time required for battery charging will be overcome. By switching to a higher thermal efficiency of the internal combustion engine with small size, light weight advantages, we can reduce the fuel consumption of the vehicle as a hybrid, plug-in high-power hybrid and even electric vehicles. We can also increase the range of support devices for the electrical powered car. All of these will have a positive effect on the environment.’
