Yanmar is releasing its first Stage V-ready engines, having received certification for complying with the European off-road emission legislation.
The 24 diesel models cover not only the stricter NOX and particulate matter standards imposed on the 19kW-and-over range, but also the more recently imposed regulations for engines introduced for the under-19kW range.
The Japan-headquartered company is making three air-cooled engines available for the under-19kW units: the L48V, L70V and L100V. The other 21 models will be vertical, cylinder-type, water-cooled versions available across the power ranges, including the 4TNV94FHT unit for the 56kW-and-over market.
The EU Stage V standards will come into force during 2019 and 2020. Yanmar’s offering of diesel engines sold in Europe will be suitable for a variety of industrial vehicles such as construction and agricultural equipment.
For models with an output of 19kW or more, the permitted values for NOx and PM emissions are one level stricter than existing standards. New PN standards have also been set, making the new European emissions standards generally the strictest in the world.
Some diesel engine models operating in the European market now require engine management systems to limit operation in the event of a malfunction in emission control systems or if the engine has been illegally modified.
