In this 100-page book we turn our expert attention to the world of vehicle emissions – those devices that carmakers have added to our engines/exhausts to help reduce tailpipe emissions. From the early days of the Lambda sensor controlling the catalytic converter, to the introduction of diesel particulate filters and exhaust gas recirculation valves, to Stop-Start systems and ‘on-demand’ water pumps. Learn how they work and what you can do to cure a faulty unit.
