Piezo injector

The Continental injector has hundreds of little piezo slices stacked on top of each other so that the combined expansion increases the total motion. The Bosch Piezoelectric (crystal) injector operates using a crystal stack, usually Quartz, that changes size when energized. The piezoelectric effect states that when a crystal such a Quarts is.

When the switching voltage is applied the plates expand opening the needle and allowing pressurised fuel into the cylinder. The pressure to reduce emissions of diesel engines is growing. One way to achieve this is to make the combustion of the fuel within the cylinder more efficient. Find great deals on eBay for piezo injectors. When you apply current to quartz, it.

Rival diesel fuel- injector suppliers are fighting a technology duel to win new business as tougher EU emissions rules take effect before the end of the decade. General description Common Rail injectors make possible fine electronic control over the fuel injection time and quantity, and the higher pressure that the common. Due to high working pressure, operating conditions.

Injectors are electrically operated valves which accurately control the quantity of fuel delivered. By adding the fuel to the air sucked in by. The purpose of this test is to check a PD injector current draw under different operating conditions non intrusively.

A failed injector will give a reading of 4– 5Ohms or less. The common-rail system with piezo injectors by Bosch enables the flexible injection of fuel at pressures up to 7bar. This feature is not available right now. The ASNU equipment is a highly advanced injector solution offering diagnostic, test and service function across a wide range of petrol vehicles, for standard injectors and piezo injectors. We are able to clean, test and refurbish the majority of petrol fuel injectors , including piezo and standar old and new, for the vast majority of makes and models.

Traditional fuel injection systems are solenoid based. Now a growing number of automotive companies are backing piezoelectric systems to deliver fuel more accurately. TDI Common Rail CR Engines. All injectors supplied are all brand new Bosch units and Digitally Calibrated to the most extreme.

A full surcharge refund of £will be made on condition your old diesel fuel injector is returned to us. The Piezoelectric Injectors fuel pressures 0bar or 40psi. Piezo Injector Upgrade for Earlier 3. The Fuel Injection Pump supplies pressurised fuel. Even so, the total expansion of. While ago I began to take an interest regarding cleaning and diagnostics of piezoelectric injectors.

Unfortunately, then there were no options available – but now. Diagnosing Injector Performance. The piezo actuator develops some ten times more power than a solenoid valve, and is thus less sensitive to minor fuel impurities. For precisely metering the tiniest amounts for advance and post- injection , as well as for consistent quality over its service life, the inline piezo injector satisfies the highest standards.

Thanks to its modular design, this system can be adapted to the. The piezo injectors which are highly accurate and precise is what has enabled such low fuel consumption and cleaner combustion. I recently test drove the c2cdi be and was very impressed with.
