Ways to Meet Future Emission Regulations for Agricultural Tractor Engines 2001-26-0007

After a review of current and future emission legislation for non-road engines (India, Europe, USA), the various options available to reduce the emissions of diesel tractor engines are discussed. Special emphasis is put on naturally aspirated engines in the 37 - 50 kW power range.
AVL has recently designed and developed several naturally aspirated heavy-duty diesel tractor engines to comply with current exhaust emissions standards for the Indian domestic and the US markets (EPA Tier 2). In doing so, different levels of technologies were applied. Their impact on mean effective pressure, specific fuel consumption and emissions will be shown. The future non-road engine exhaust emissions legislation in different markets will be addressed (India, Europe and USA). Compliance with the new emission standards will require the introduction of more advanced technology. Based on in-house research work, an outline will be given on the measures needed to be taken, and their implications with respect to engine performance and cost discussed.
