Fuel Injector Testing

In the ever increasing demand for fuel efficiency, greener emissions and enhanced engine performance ASNU Corporation Europe Limited has created a special purpose program of injector diagnostics. ASNU’s 26 year history is testimony that the Company are a World leader in this exacting commercial arena.

ASNU’s constant strive in research and development has led the Company into sectors of the major vehicle manufactures, specialist performance, mass transit, commercial vehicles, aviation and marine

ASNU have over 25 years of experience with injectors from all the various injector manufacturers from around the world. ASNU are represented in over 38 different countries, with thousands of injectors being tested and serviced in Aftermarket and Motorsport worldwide; a programme and experience unrivalled by anyone else in the world. This gives ASNU the greatest experience and understanding to develop a range of injectors that will do exactly what they are designed for – Correct Performance. ASNU Performance Injectors are a purpose designed and built injector with the ideal spray pattern to match the flow required. They are designed to meet the varied demands of the Racing & Performance markets.

Fuel Injector Testing

All ASNU Performance Injectors have a multi-hole orifice cap, cut using the latest laser technology for greater accuracy and repeatability. Using this technology allows us to produce injectors with specific spray patterns and flow rates to meet the customers’ exact requirements. The seven hole orifice cap that we use in most of our injectors in the lower end of the range (300-1000cc) and offer an ideal combination of Fuel Flow, Fuel Distribution and Fuel Atomisation. The seven holes produce smaller fuel droplets that will burn more efficiently, giving more performance and more laps for less fuel. This is a critical factor for fuel injector testing and should be considered when comparing ASNU injectors to any other Performance injectors.

A) ASNU Classic GDI

ASNU are manufactures of the world leading Gasoline Injector Diagnostic Testing & Servicing Systems & have distribution in over 60 countries worldwide

ASNU offer a range of systems to suit all markets;

Aftermarket Service & Repair Workshops, Fuel Injection Specialist Workshops, Racing Engine Builders, High Performance Tuning Shops, Motor Cycle Performance and Racing Specialists, Motor Cycle Service & Repair Workshops, Marine Racing Performance and Racing Specialist and Marine Service & Repair Workshops.

On a GDI system, the fuel is injected directly in to the combustion chamber at a much higher pressure than manifold systems, up to 200 bars.

These systems now require fuel pumps and injectors made of stainless steel and must be capable of performing at a much higher specification than ones seen on previous manifold injection systems. Both designed to deliver very precise quantities of fuel at extremely high pressures and in short periods of time, in some cases for fractions of a milli second.

To control these systems, the ECU is also of a higher specification and required to supply a higher current of up to 90v on some systems. There are many manufacturers of this type of system, but Robert Bosch is recognised as one of the leaders in the development of the GDI Technology.

B) ASNU PIEZO Adapter Box

Diagnosing Injector Performance

Piezo injection is the current system of choice of major executive vehicle manufacturers. Piezo injectors can respond so quickly that they can allow the vehicle to run at incredible air/fuel ratios of up to 60:1 in some engines. Compared to standard vehicles running at 14:1 air/fuel ratios, this means the minimum amount of fuel is used and the exhaust emissions are virtually non-existent, while still maintaining excellent drivability and performance.

As you can imagine, the performance of these injections is critical, maintenance should not be an option, it should be mandatory. How often do you check your Piezo injectors?

In conjunction with a world leading vehicle manufacturer, ASNU have created this purpose built adapter box.

C) ASNU PIEZO Adapter Box

The ASNU GDI Adapter Box has been designed to drive Gasoline Direct Injection (GDI) injectors with an approved supply of current and voltage to simulate injector electronic operation as on the engine. Correct Electronic Operation is critical when examining the injector’s response to changes in mS & RPM. Examination of the Fuel Injector Testing injectors Fuel Distribution and Atomisation is equally critical to the Engine’s Correct Running, Performance, Fuel Economy and Emission Outputs. Even the slightest irregularity in the Fuel Spray pattern would result in illumination of the Engine Check Light, but with no specific cause identified.

GDI injectors are difficult and time consuming to remove and re-fit, would you fit a new set of injectors without ensuring they are working correctly?
