Kyoto, Japan - HORIBA, Ltd. (hereinafter referred to as "HORIBA"), the global leader of exhaust gas analysis technology, adds the FTX-ONE-CL and FTX-ONE-RS as two new products in the FTX-ONE exhaust gas analyzer series. Both use HORIBA's "polished-over-many-years" Fourier Transform Infrared Spectroscopy (FTIR)*1 to continuously and precisely measure the gas concentration of up to 28 components contained in exhaust gases.
These new FTIR exhaust gas analyzers contribute not only for research and development in the context of emissions regulations, but also for carbon neutrality.
“As demand for carbon neutrality and better air quality grows, initiatives are being taken to tackle everything from the adoption of new fuels and new power drives to the development of more advanced technology to control exhaust gases in not only the automotive industry, but also construction machinery, marine vessels, and other various sectors using internal combustion engines. We have developed exhaust gas analyzers based on a variety of analytical principles in an effort to satisfy the societal changes," said Kazuya Tsurumi, General Manager of the Mobility & Energy Business Division at HORIBA, Ltd., who led the development of the product. "Over the past 30 years we have developed our unique FTIR exhaust gas analyzers. The utility of this emissions analysis method has come into the spotlight due to the recent approval for use in certification testing under emissions regulations in the United States and Europe.”
1. FTX-ONE-CL for dilution measurement
By introducing our proprietary high-performance optical cell dedicated to long optical path lengths*2, low-concentration components of diluted exhaust gases can now become precisely measured.
- Target gas: non-methane organic gas (NMOG), nitrous oxide (N2O), formaldehyde (HCHO), and ethanol (C2H5OH)
- A compact design with a footprint and weight these are about 1/2 compared to our conventional models.
- The improved durability and portability make it possible to flexibly adapt to changes in the layout of analytical equipment in the laboratory.
2. FTX-ONE-RS for direct measurement
The adoption of the world’s smallest*3 high-performance optical cell as an FTIR exhaust gas analyzer reduced the gas displacement time 40% (compared to our conventional FTIR model) that enables a fast response time of roughly 1.5 seconds/output interval of 0.2 seconds.
- Target gas: Direct measurement of ammonia (NH3) and methane (CH4) concentration in exhaust gases.
- Can also be equipped with total hydrocarbon (THC) and oxygen (O2) analyzers so that a single unit of FTX-ONE-RS can analyze the emissions behavior of multiple components. Also, standalone EGR system can be integrated as an option.
- The versatility offers a broad range of applications from the monitoring of the air-to-gasoline ratio supplied by an engine to the evaluation of multiple new fuels and H2 engine development.
[Reference] Regulated components in motor exhaust gas:
- NMOG and N2O: Regulated by the United States Environmental Protection Agency (EPA) in its current exhaust gas standards (LDV Tier 3) *4
- N2O, HCHO and C2H5OH: Currently under review in the final EU standard (Euro 7) which will go into effect soon.
- NH3: Required in regulations such as the current EU heavy-duty vehicle emissions standards (Euro V).
The commitment of HORIBA Group to contribute to global environmental conservation is advocated in its corporate philosophy. In order to achieve carbon neutrality, the Group responds to a broad range of needs from the development of new fuels to compliance with ever-stricter exhaust gas regulations rolled out by each nation worldwide.
*1: A method for the determination of components from the absorption pattern produced by irradiating substance with infrared light in two different paths.
*2: Developed in-house for optimum gas displacement rate and sample flow.
*3: According to our research in May 2018.
*4: Emission limits for light duty vehicles and heavy-duty vehicles meeting certain conditions.
