The new FLEX system will help lower emissions from the latest Kohler engines
An improved range of diesel engines has been developed by 8648 Kohler and its Italian business, Lombardini. The new diesels utilise the KOHLER Flex package, an integrated suite of engine systems. The firm is offering a single engine platform for world market, while being able to meet the new Stage V requirements.


The new engine platform is designed to meet needs from customers for greater application flexibility, as well as compliance with the various emissions limits. Meanwhile the engines also offer high performance and productivity. According to Kohler the engines provide compact design, best-in-class performance, reduced fuel consumption, easy installation, and optimised solutions for every emissions regulation.

The firm says its engines provide clean combustion and advanced technology for aftertreatment. The novel DPF smart regeneration system has been developed through extensive use of advanced simulation tools and testing. Kohler’s exclusive regeneration strategy is completely transparent to the end users in every application and duty cycle.

KOHLER Flex is a range of solutions for emission control and at its heart is the clean combustion design that allows the use of a compact DPF to meet the Stage V emission standard. KOHLER Flex combines the clean in-cylinder combustion of KDI engines, made possible by high-pressure common rail, four valve head, turbocharger and cooled EGR, and the most compact aftertreatment devices (DOC, DPF and SCR) to comply with all emission requirements. The firm also says that the package also helps to minimise changes for engine installation into existing packages. These systems can be deployed in many combinations to achieve effective emissions solutions for the different markets.

    John Deere Power Systems used bauma to complete its engine line-up for Tier 4 Final/Stage IV emissions regulations. This included the arrival of the PowerTechTM PWL 4.5L engine, which meets emissions regulations without a diesel particulate filter (DPF). Spanning outputs from 63-104kW, this four-cylinder, 4.5litre engine offers reduced cost and improves engine packaging by eliminating the DPF, said Deere. However, the engine uses selective catalytic reduction (SCR), a diesel oxidation catalyst (DOC) and coo
