Micro power makes sense

摘要

'Mega' solutions are not necessarily the best approach to large-scale environmental problems. In fact, as our story on page 4 demonstrates, the solution to one of South-East Asia's, and the world's, biggest vehicle pollution problems - the millions of two-stroke motorcycle and tricycle engines belching fumes into the atmosphere - can be as simple as a low-cost engine retrofit.rnUS non-profit company Envirofit adapted the engine retrofit kit from a similar one developed to reduce emissions from snowmobiles. The kit works by eliminating the carburettor and introducing fuel directly into the engine. This reduces fuel and oil consumption by 35-50 per cent and cuts engine emissions by as much as 90 per cent.
