Niftylift Engines - EPA Tier 4 Final Compliance
Everything you need to know about Niftylift's Diesel Engine compliance with the EPA Tier 4 Final emissions standards for Mobile Elevating Work Platforms.
Friday 23 October 2020
Background
In the United States, engine-exhaust emission regulations are governed by US legislation to aid the control of emissions and reduce pollution.
By setting more stringent future emissions targets, this legislation encourages engine manufacturers to develop and produce cleaner engines as technology develops.
The US emissions standards for engines used in Non-Road Diesel Engines (NRDE), which includes Mobile Elevating Work Platforms (MEWPs), have been structured into tiers and harmonized to a certain degree with European standards.
In order to set specific gaseous and particulate emission targets NRMM engines are categorised by engine power output, as shown below:

From EU Stage V, Regulation 2016/1628 specifies emission requirements for all categories of compression ignition (Diesel) engines and positive ignition non-road engines and replaces Directive 97/68/EC and its amendments.
All Original Equipment Manufacturers (OEMs) must comply with these requirements and fit engines that meet the regulations above by the dated deadline shown.
Transition periods beyond the deadlines have been granted giving OEM’s and engine manufacturers more time to comply and to use scheduled stocks of older models, higher-emission transition engines. For example, for engines below 56kW, EU Stage V compliance came into effect in January 2019 and there was a transition period granted up to the 30th of June 2020. Due to the COVID–19 pandemic, this transition period has been extended by the EU Parliament by a further 12 months.

Niftylift Stage V Compliance
Niftylift produces a wide range of MEWPs with power systems that include: Electric, Diesel and Hybrid variants.
All Niftylift Diesel-powered models are EU Stage V compliant and have been since the original EU deadline of January 2019. They are also all below the 19kW power rating, even Niftylift’s largest model the HR28 Hybrid, which uses a Kubota D1105 3-cylinder engine with a power output of 18.5 kW.
Through design optimisation, Niftylift has developed a range of compact, low-weight machines that are high-performing, efficient and environmentally conscious. Their efficient fluid-power and drivetrain systems enable the use of the smaller, simpler Diesel engines that offer significant advantages to owners and users, without any loss to their power-to-weight ratio.
Benefits of Niftylift Diesel Engines
When compared to the heavier, higher-powered MEWP’s from other manufacturers these benefits become even more apparent.
Larger engines are subject to tighter control and monitoring measures and need complex control systems to monitor and manage their emissions. If these emissions limits are not adhered to, alternative measures such as machine-usage restrictions can be enforced, greatly reducing their effectiveness.
Niftylift’s Diesel engines are all below 19kW and comply with EU Stage V regulations without the need for any post exhaust control measures such as Diesel particulate filters, exhaust gas recirculation, Diesel oxidation catalysts or Diesel additives. They are fuel-efficient with lower levels of exhaust gas emissions and don’t require the complex electronic emissions control systems.
This means that Niftylift engines emit lower levels of particulate and gaseous emissions to the environment and are also quieter to run than their larger competitors. They are less expensive, less complex and have simpler maintenance schedules resulting in lower replacement costs for consumables, reducing both their running and lifetime ownership costs.
