Yanmar Develops New Industrial Gas Engines

Yanmar has developed gas-powered industrial engines that utilize LPG (liquid petroleum gas) and meet both U.S. EPA※1 Tier2, CARB※2 Tier4 and EU Stage V emissions regulations. Adding the two clean burning and quiet industrial engine models, 4TN88G: maximum output 45.0kW※3 and 4TN98G: maximum output 63.0kW※3 to its lineup, Yanmar is ready to better meet the diverse needs of its customers. Furthermore, Yanmar has plans to introduce bi-fuel※4 specification models that can run on both LPG and gasoline.

Gas engines produce very little PM (particulate matter)※5, and are comparatively quieter than diesels. This makes them ideal for work indoors and in enclosed areas, where environmental concerns are a major consideration.

Yanmar has more than 30 years of experience working with gas engines. This long-earned experience together with our deep knowledge of industrial diesel engine technology has allowed us to develop a proprietary gas combustion system for high output, fuel efficient and compact engines that display the durability and reliability required of industrial applications and deliver new value to our customers.

Yanmar can now provide customers with a “One-Stop Solution”, whereby Yanmar can offer either a diesel or gas power source in one-stop sales contact, with maximum compatibility to the customer’s equipment.

With the addition of these new gas engines to Yanmar’s existing industrial engine lineup, Yanmar is well placed to meet customers’ demands with a versatile range of power solutions.

Main advantages

Higher specific power, Yanmar’s proprietary engine control system optimizes the air intake to achieve even greater power and torque than our diesel engines. The result is uncompromising performance for our customers’ machinery with the benefits of using gas as a fuel.   

(1)   Class leading fuel efficiency With long experience in the development of gas engines, a combustion system optimized for LPG has been realized by implementing a high compression ratio and reducing intake pump loss. This has yielded fuel consumption reductions of 10%※8 compared to current mixer systems※9 resulting in longer operational hours for a same sized LPG tank, and reducing the lifecycle cost for the customer.  

(2)   Endurance and reliability of a diesel engine block Basing the engine on the superior endurance of Yanmar’s industrial diesel engine crankcase, together with optimized cooling systems and materials for heat resistance in high-temperature components such as cylinder head, intake and exhaust valves, and pistons, means that the endurance and reliability required of industrial engines is realized, even at the high combustion temperatures characteristic of stoichiometric combustion.  

(3)   Compact engine configuration Yanmar’s proprietary compact air-fuel mixing system results in a smaller engine (by approximately 9%) by eliminating the conventional gas engines with mixer system. Furthermore, our experience in installing industrial diesel engines to a variety of industrial machinery means that the engine layout is optimized to enable easy installation to forklifts, construction equipment, agricultural equipment and more.  

(4)   Compatibility with diesel engines By using the same application components and application software interfaces as those used with the machines and service tools on the market for use with Yanmar’s diesel engines, a high degree of compatibility has been secured between the diesel and gas engine installations.

Industrial diesels with a maximum output of 155 kW: 4TN101, 4TN107 

The two new high-output, industrial diesels that made their world debut at Intermat in Paris in April, 2018: the 4TN101 (maximum output: 105kW) and the 4TN107 (90-155kW) with two-stage turbocharger, will be shown once again at BAUMA. This time, the 4TN107 with single-stage turbocharger will, for the first time, feature its DOC※6+DPF※7+SCR※8 emissions after-treatment system.

The after-treatment system utilizes Yanmar’s proprietary DPF regeneration technology already successfully fitted to the common rail TNV series and renowned for its reliability. Yanmar has also developed a mixer-less SCR solution which results in lower back pressure than the mixer configuration and consequently allows more freedom in the designing of the exhaust tail pipe on the vehicle.

The standard after-treatment units are a compact design to match the width of the engine which allows Yanmar to offer a range of optimum layout options for different construction equipment, agricultural equipment and materials handling applications. The configuration of the device simplifies customers’ design requirements for the engine’s installation to equipment, while improving external accessibility, and the fact that no special service tools are required results in reduced maintenance time and increased uptime for customers.

European StageV Emissions Regulations Compliant L-V Series Of Air-Cooled Industrial Diesel Engines 

From the first sales of the L Series in 1983, the world’s smallest and lightest air-cooled industrial diesel engine has been praised for its outstanding performance in compact construction equipment, agricultural equipment and for power generation.

Now, the L48V (maximum output: 3.4 kW) has been redeveloped to achieve European StageV emissions certification.

To meet the new strict regulation limits for below 19kW range in a bore of only 70mm, the L48V utilizes a proprietary fuel injection technology based on Yanmar’s direct injection system, together with a diesel oxidation catalyst (DOC), while maintaining the reliability and fuel efficiency the engine is well known for.

Not only the new L48V, but also the L70V (maximum output: 4.8kW) and L100V (maximum output 6.8kW) are certified to EU StageV by the adaption of an exhaust gas recirculation (EGR)※9 system from the current L-N series. The L-V series will be presented at BAUMA.

EUROPEAN STAGE V OFF-ROAD EMISSION STANDARDS (EU STAGE V)

▪ The new European emissions standards, commonly referred to as "EU Stage V", will apply to engines installed in off-road mobile equipment, as stipulated according to engine output. The standards come into effect over 2019 to 2020. These EU Stage V standards will also be applicable to diesel engines with an output range of less than 19 kW which were previously not targeted by the existing standards.  
▪ For models with an output of 19 kW and more, the permitted values for NOx and PM emissions are one level stricter than existing standards. In addition, new PN standards have also been set making the new 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. 

*1 NOx: Nitrogen oxides such as Nitrogen oxide (NO) and Nitrogen dioxide (NO2). 
*2 PM: Particulate Matter. Airborne particles such as soot. 
PN: Particulate Number. A standard that regulates the number of particulates contained within a mass unit of emissions; separate from the existing PM standards that regulate the mass of particulate matter contained within a mass unit of emissions.
