How Common Rail Diesel Injection Works

How Accepted Lambaste Diesel Injection Works


The Clean Car of Tomorow


Most Americans consider of diesels as the noisy, sooty, smelly engines introduce by Detroit automakers in the 1980s, on the other hand the technology has been usual in Europe for decades. With late Disinfected diesel technology, diesel cars are poised to build the leap across the Atlantic and incline a credible Election for consumers who demand cleaner, aggrandized fuel-efficient vehicles.


Common Rail Diesel Technology and Development


Common Rail Diesel engines are most common in Europe where diesel cars already have a large share of the market due to high gas prices. Auto companies that have used CRD include Alpha Romeo, Mercedes-Benz, Renault, Volvo and BMW. The American automaker Chrysler has also adapted the technology for some of its light trucks. Early CRD systems relied on magnetic solenoids to control the fuel metering process, but later systems have turned to Piezo crystal wafers, which have the notable characteristic of expanding rapidly when an electric current is applied.


Advantages


Modern Common Rail Diesel engines have many advantages over their earlier diesel counterparts. The precise metering and increased atomization of fuel results in better fuel efficiency and fewer emissions. CRD engines also run quieter and are more powerful.


Applications


The Familiar Castigate Injection Action (CRIS), bounteous commonly avowed as Common Rail Diesel (CRD), was developed by the Italian automaker Fiat and filtered by Bosch, a German manufacturer. The development uses a colloquial castigate to preserve altitudinous fuel vigour regardless of engine RPM. This way that the diesel fuel injectors can also exactly metre outside minor amounts of fuel at a more precise time in the combustion process. A high pressure fuel pump governed by the engine control unit generates pressures of up to 1,600 bar. Fuel is pushed through ridged tubes to the injectors, which then spray the fuel into the combustion chamber.
