New low maintenance engines from Yanmar

Engine manufacturer Yanmar is unveiling three additional engines, to fill gaps in its existing line-up. The 1.6, 2.1 and 3.1litre engines will all be built to comply with the upcoming EU Stage V emissions standards. The smaller engine is a three-cylinder motor offering 33.3kW of power. The smaller of the two four-cylinder engines delivers 48.5kW, while the largest engine is offered with 69.8kW, 77.2kW or 88.4kW ratings. This largest engine will utilise both DPF and SCR, while the lower powered motors will

Yanmar is developing new compact diesel engines
Engine manufacturer 7139 Yanmar is unveiling three additional engines, to fill gaps in its existing line-up. The 1.6, 2.1 and 3.1litre engines will all be built to comply with the upcoming EU Stage V emissions standards. The smaller engine is a three-cylinder motor offering 33.3kW of power. The smaller of the two four-cylinder engines delivers 48.5kW, while the largest engine is offered with 69.8kW, 77.2kW or 88.4kW ratings.

This largest engine will utilise both DPF and SCR, while the lower powered motors will come with just a DPF. Yanmar has designed the engine to run for 6,000 hours with no DPF maintenance, thanks to a two-stage regeneration system. Assist regeneration throttles the engine intake to raise exhaust temperatures to 350 degrees C for partial regeneration. Reset regeneration is carried out by a service engineer and lifts exhaust temperatures to the full 600 degrees C using post injection into the engine.
