We provide ageing services and testing to help OEMs meet emissions targets faster and with higher accuracy and flexibility. Our process delivers accurate and reproducible outcomes for Full Useful Life (FUL) and OBD Limits ageing.

We work with leading OEMS to develop future catalysts to meet emissions standards for new models.  CATAGEN can provide Catalyst Ageing Services for any size of non- road engine such as lawnmowers, leaf-blowers, chainsaws including: 

  • Accelerated Bench Ageing

  • Full Useful Life Test
    Custom OEM Cycles 



    US – The US Environmental Protection Agency (EPA) has adopted emission standards to control both exhaust and evaporative emissions from small spark-ignition engines. They state that nonroad engines contribute significantly to air pollution. The emission standards address oxides of nitrogen (NOx), hydrocarbons (HC), particulate matter (PM), and carbon monoxide (CO). 

    EU – All engines are rated on emissions of Total Hydrocarbon (NOx), Non-Methane Hydrocarbons (NMHC), Carbon monoxide (CO) and Particulate Matter (PM).  Manufacturers have a responsibility to ensure any new models conform to the new specification and therefore are compliant for sale in the EU.


      According to the U.S. Environmental Protection Agency (EPA), a new gas powered lawnmower produces volatile organic compounds and nitrogen oxides emissions air pollution in one hour of operation as 11 new cars each being driven for one hour.

      • Battery equipment would have limited charge during blackout periods.
      • Ageing cycle not defined.
      • Zero-emission commercial-grade equipment tends to cost more than parallel gas-powered equipment.
      • The battery equipment may not have the efficiency scales of the existing gas-powered lawn mowers, leaf blowers, and other small machinery.
      • Batteries present an uncertain expense, and a crew may have to carry multiple batteries to complete a day’s agenda.


      Not all machines can easily move to electrification but will require more efficient catalysts.  CATAGEN can work in partnership with you to develop your newest model of machine to meet emissions standards globally.


      According to the U.S. Environmental Protection Agency (EPA), LPG-burning forklift trucks account for more than 60 percent of all material handling vehicles and more than 80 percent of all internal combustion forklifts used worldwide.

      Since 2018 some of the world’s toughest emission standards have been phased-in for Forklifts including EU Stage V with full enforcement from 2021.  All IC engine trucks, both diesel and LPG, will have to comply regardless of engine size.

      • Limits on emissions of particulate matter are to be reduced by a further 40% – taking the current Stage IV A limit of 0.025 g/kWh of soot down to 0.015g/kWh – and this will apply across all engine sizes.
      • Carbon Monoxide emissions will be set at 5.0 g/kWh for all engines up to 128kW and emissions for NOx and HC will remain as currently specified.
      • To eliminate nitrous oxides a three-way catalytic converter will be necessary.
      • The biggest impact of these new standards will fall on diesel models, most of which already require diesel particulate filters (DPFs) to comply with current standards.
