Launch of Simple and Selectable Multi-gas Measurement System (NCEM)

Nagoya, April 2, 2018―NGK SPARK PLUG CO., LTD. (Chairman, President, and CEO: Shinichi Odo, Headquarters: Nagoya, hereafter NTK) is pleased to announce that the company released simple and selectable multi-gas measurement system (NCEM).

In recent years it is required to measure exhaust gas during on road drive as the exhaust gas regulation becomes more and more strict all over the world. Especially in European region the RDE (Real Driving Emissions) regulation (*1) was introduced in September 2017, and there is a growing need for such devices that are able to measure particles in exhaust gas during actual driving. We have developed this compact multi-gas measurement system (NCEM) making maximum use of our exhaust gas sensor for OEM, while anticipating this need, aiming to develop and evaluate vehicles and to investigate exhaust gas in the market.
NCEM is a compact and light exhaust gas measurement system that is able to be used for multiple purposes. It can measure not only NOx (nitrogen oxides) and O2 (oxygen) proven for our OEM sensors, but also PM (mass concentration of soot) and PN (number of particles of soot) by combining diffusion charging type principle method and the latest sensing technique. Because sensors are installed directly in the exhaust gas flow, measurements can be performed with excellent responsiveness and in real time.
We will continuously update measurement parameters and data analysis functions in response to customer's needs.

We will keep working on product development integrating our technologies and ideas so that we can contribute to the environmental society through our various types of sensor products.

(*1) RDE (Real Driving Emissions) regulations
A common name for actual driving exhaust gas evaluations to investigate exhaust gas while actually driving on public roads using vehicle equipped with a vehicle-mounted exhaust gas measuring device
(*2) Diffusion charger method
A calculation method of measuring the number of PM and total volume by charging each PM in the sensor and measuring its electric charging amount

■ Appearance


■ Product features


1. Lightweight and compact

-Weigh only approximately 1/3 of existing PEMS (Portable Emissions Measurement System: exhaust gas measurement system for automobile)

*With standard specifications: 12.5kg (Main unit +PM/PN module +NOx module +AFR module)

-Can be loaded into compact cars and no influence on emission

-Can be carried by a single person


2 . Easy operation

-Easy operation by using a touch panel

-Easy put on and take off cables


3. Lower power consumption

-Maximum power is 300VA, approximately 1/10 of that of PEMS

-Can be powered by most of vehicle batteries


4. Many potential application methods to match your testing needs

-Can be used in engine bench, chassis dynamometer, and real world testing

-Modules of 8 slots can be chosen, you can customize it depending on your needs

-More various measurements will be realized by increasing the number of sensors and modules applicable for this system



Directly inserting the sensor into the exhaust pipe makes it possible to measure changes in the concentration of the target substance without delay









Used for the actual vehicle driving test by placing the driving wheel on the roller connected with the dynamometer instead of on the road









Can be installed on the back seat for the measurement because it is compact and easy for setting










5. After-sales-care

-Established global service structure to take care of customer's various troubles and to supply replacement parts after sale
