The first such systems were introduced into racing engines such as those used for Formula One, but it was not long before these found their way into everyday cars.Ī hybrid digital design was popular in the mid-'80s. It was not until around 1987 that digital electronics and embedded microprocessor systems became fast enough to process engine parameters in real time. This is also referred to as an (electronic) Engine Management System (EMS).Įarlier ECU designs were based more on analogue computer circuitry, because analogue circuits are not limited by clock speed.

The software is stored in the microcontroller or other chips on the PCB, typically in EPROMs or flash memory so the CPU can be re-programmed by uploading updated code. The main component on this circuit board is a microcontroller chip (CPU). The hardware consists of electronic components on a printed circuit board (PCB). An electronic control unit contains the hardware and software ( firmware). Modern ECUs use a microprocessor which can process the inputs from the engine sensors in real time. In addition, to a large degree it is able to compensate for the gradual wearing of the engine as it ages, which in practice allows it to extend engine life to two or three times that of engines of twenty years ago. Because the ECU is dealing with actual measured engine performance from millisecond to millisecond, it can compensate for many variables that traditional systems cannot, such as ambient temperature, humidity, altitude (air density), fuel octane rating, as well as the demands made on it by the driver. This approach allows an engine's operation to be controlled in great detail, allowing greater fuel efficiency, better power and responsiveness, and much lower pollution levels than earlier generations of engines.
