This task evaluated engine performance using a Hydroprocessed Renewable Diesel HRD fuel that meets ASTM D975 No. 2 diesel specification, over both ambient-temperature and desert-temperature endurance cycles, to performance and engine emissions observed under similar conditions using a petroleum-based Reference Diesel Fuel RDF. The use of Hydroprocessed Renewable Diesel fuel in the Caterpillar C7 engine provides adequate performance without any significant negative impact on engine durability, emissions, performance, fuel consumption, lubricant degradation, or cleanliness. The use of the Hydroprocessed Renewable Diesel fuel for the C7 engine is sufficient for both the ambient operating condition and the desert operating condition.
