Alongside my energy saving work I've got problems with my car that's caused me to study in more detail how a modern car works. The problems I'm experiencing relate to the electronic management of the engine but it's occurred to me how the homes we live are years behind the technology used in most of the cars we drive every day and take for granted.
A modern car uses a wealth of sensors to gather data from many parts of the drive, chassis and engine components to make sure it is running safely and efficiently. For example, the engine management computer, in order to optimise efficiency, measures parameters such as the air flow entering the engine, the inlet manifold temperature and its pressure many times a second to control the fuel flow, turbo pressure and recycled exhaust gas . The electronics and components to achieve this are cheap and mass produced. So if this advanced energy saving technology can be applied to even the most standard of cars I'm sure similar systems would make a significant contribution to energy usage in homes.
