The line on the graph demonstrates the flat torque output across the rev range, perfectly tuned to industrial applications. So whether you are designing a machine for construction, mining or agriculture you can be sure of a consistent output whether it's geared towards drive or ancillaries like a bucket or forks.
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.
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.
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.
※8 Figures calculated by comparing the tested value of Yanmar’s mixer-type gas engines with the new gas engines.
※9 Mixer system: The system uses air-gas mixer which is designed with the structure of venturi effect.
