The job of the high-pressure pump is to consistently supplies fuel into the high-pressure accumulator (rail) for storage and use. The pressure are now more than 2,000 BAR (29,000 Psi). The pressure produced has no relevance to engine speed, meaning the pressure needed is already available at low engine speeds.
Common Rail Injectors must calibrate to the highest degree of accuracy. To achieve this we use a computerized test bench. Common rail injectors work under high-pressures, reaching up to 2,000 BAR (29,000 Psi) from the Common Rail. The frequency of injections varies from 3 to 7 injections each cycle, in comparison to a mechanical single injection. This allows diesel fuel to burn cleaner because of less exhaust emissions. Diesel is fast becoming an alternative for a cleaner, greener-loving population of drivers.
