Unveiling Diesel Cetane: Your Key to Enhanced Engine Performance

Ever wondered why some diesel engines run smoother than others, despite similar designs? The secret often lies in the cetane rating of the diesel fuel used. Similar to the octane rating in gasoline, the cetane number in diesel is crucial in determining fuel performance once it’s fired up in your engine.

What exactly is cetane, you ask? Well, cetane numbers measure the combustion quality of diesel fuel. High cetane means the fuel ignites swiftly after being injected into the engine. This quick ignition leads to a more complete combustion, enhancing engine operation and efficiency. Generally, commercial diesel fuels sport cetane values between 40 and 45, which meet operational standards but might not be the best your engine can get.

Mark Nyholm, a seasoned mechanical engineer and AMSOIL Product Manager – Heavy Duty, sheds light on the economic side of cetane ratings. He suggests that cetane numbers are primarily set by economic factors from a refinery’s standpoint. Raising cetane values could hike up costs, a move the market might resist due to a lack of awareness about the benefits of higher cetane numbers.
