Diesel Engine Electronic Control Technology also facing many issues that need to be resolved, especially when using high-voltage controlled fuel injection, diesel engine electronic control system costs accounted for almost half of the cost of the engine. Nevertheless, only in the automotive diesel engine electronic control technology widely used to the face of increasingly stringent emissions regulations challenges. Diesel electric control system in recent years the development momentum is remarkable. The use of diesel vehicles to a maximum of Europe, for example, the European road vehicles with multi-cylinder diesel engine from the beginning of 2000 emission standards for the implementation of the EU 3, the electronic control technology has been in Europe to meet the three standards on the widespread use of diesel engines, some research institutions and large the manufacturers have already begun to meet the EU-4 emission standard electronically controlled diesel engine, now electronically controlled common rail system and the electronic control unit pump system in the application of multi-cylinder diesel engine has been significantly increased.
