The global market for sensors used in internal combustion engines (ICEs) is on the road of steady growth for the next few years, propelled by increasing utilization in engine management and exhaust aftertreatment, according to IHS. Sensor shipments for ICEs will top 1.34 billion units in 2019, up from about 1.08 billion in 2013. Overall, the projected six-year compound annual growth rate (CAGR) from 2013 to 2019 will equate to 3.6 percent. "Shipments of ICE sensors are growing slightly faster than car shipments," said Richard Dixon, Ph.D., principal analyst for MEMS and sensors at IHS. "The main reason is that new concepts in emissions mitigation in the engine and in exhaust aftertreatment systems require advanced sensors for their operation. Added to that, emission legislation in some major markets of the world, such as China, is beginning to catch up with that of mature markets like the US, Europe and Japan, at least in the larger cities."
