How Diesel Engines Have Become Cleaner Than Ever
Diesel engines are durable, fuel-efficient and provide the necessary power and torque for moving big loads. As these engines have become more powerful, they have become cleaner! Recent improvements in technology have reduced emissions, made exhaust cleaner, and improved the fuel efficiency of trucks, even as the loads have become larger.
Now, commercial semi-trucks no longer expel black smoke, leave a lingering diesel stench as they pass, or sound loud and aggressive. Pound for pound, they are some of the cleanest vehicles available. Two major advancements went into making diesel engines cleaner than they have ever been before: better fuel and exhaust after-treatment technologies.
