Flowmeter keeps close check of engine inlets
Labcell has a new air intake flowmeter for internal combustion engines that the company believes is the lightest, most compact and the most accurate instrument of its type.
In-vehicle monitor checks air/fuel ratios
The ECM G100 is a system for in-vehicle monitoring of air/fuel ratios.
A highlight of the show will be the European launch of the AFM1540 air-fuel ratio monitor.
This is specifically designed to be compatible with the Bosch LSU4.9 lambda sensor that is so widely used, particularly in Germany.
Alternatively it can be used with the NTK sensor that is also popular in Europe.

Lambda meter helps keep engines in tune
One of the most important items of equipment for live mapping is the air-fuel ratio (or lambda) meter, and Motorsport Developments has chosen the ECM AFRecorder 1200.
Other air-fuel ratio modules to be shown include the AFM1500 and F/A1500, which output an AFR or FAR (fuel-air ratio) value, respectively, via a 0-5V linearised analogue signal, plus AFR, FAR, lambda and%age oxygen via an SMB (serial measurement bus) interface.
Using an SMB enables up to 16 modules to be interfaced to a single computer via an RS232 serial port.
Although otherwise similar to the AFM1500 and F/A1500, the cost-effective AFM1000 and F/A1000 modules being shown have only a 0-5V linearised output and no SMB interface.
Another recently launched module being shown in Europe for the first time is the OXY6200 that measures percentage oxygen in the engine exhaust or inlet.
It delivers its output in the form of a linearised voltage output signal.
All of the above modules use ECM's proven UEGO (universal exhaust gas oxygen) sensor that has a wide range, fast response and can be calibrated in the field using ambient air.
While the air-fuel ratio modules are suitable for integration with a data acquisition or control system, the ECM range of AFR analysers also incorporate a digital display.
Furthermore, the 4800R and 4800P AFRecorders are dual-channel instruments with a facility for recording data; the 4800P is a portable model ideal for in-vehicle testing.
If spark timing, engine speed and manifold pressure measurements are required, the AFR analyser 2400 model offers these additional features.
Other AFR analysers include the single-channel 2000 with built-in power supply that is suitable for dynamometer or in-vehicle testing, and the AFR analyser 1200 is a recently launched model that benefits from the full functionality of the other meters, yet it is housed in a lightweight package that makes it ideal for both dynamometer and in-vehicle applications where pace is at a premium.
Similarly, the Lambda Pro is a compact, lightweight AFR analyser.
Alongside the AFR analyser and module ranges, ECM and Labcell will also be exhibiting the Sensor Simulator.
This calibrated device is used to verify the accurate operation of any of the AFR analysers and modules.
