YTO have developed a new family of diesel, water-cooled engines, comprising a 4.6 L 4-cylinder and a 6.9 L 6-cylinder engine. These engines, to be launched in 2023, will meet the future needs and demands for engine performance, emissions and operating costs, supporting YTO products in the off-highway machinery sectors around the globe.

    The engines meet Euro Stage V and US Tier 4f emissions requirements, whilst delivering class leading performance. This paper will describe the key features of the 4-cylinder engine and the robust technology selection process. The 4-cylinder engine delivers best-in-class power and torque density (>30 kW/L and >175N m/L) for single stage, wastegate turbocharged for off-road engines. This performance is delivered with excellent fuel consumption (<196 g/kWh minimum full load BSFC).

    A digital first approach has been used throughout the design and development, with simulation used to lead design selection and confirm attributes. Working closely with the supply base, cost effective technologies have been utilised throughout. As a result, a high level of maturity was reached through the virtual engine, allowing production tooling to be used for the core components of the first design prototype, and reducing the time from first prototype to Start of Production.
