Santi S/shutterstock Heat is necessary for internal combustion, but too much heat can also wreak havoc on your diesel engine. Extreme temperatures change the shape of crucial components, causing them to crack or rub against each other, increasing tension and structural damage. It als …

Sergey Kohl/shutterstock.com You might first be asking yourself, what is diesel? Diesel engines are the backbone of the trucking industry, linking homes, businesses and warehouses to the global supply chain. They also power boats, generators and highly efficient cars that get 50 mpg …

Philip Lange/shutterstock.com Diesel engines run on highly compressed air and fuel. The turbocharger on a diesel engine increases airflow via compression so more can fit inside the combustion chamber. This produces more energy for faster acceleration, fewer emissions and better fuel …

Ensuper/shutterstock.com All motor vehicles need oil. It adds a protective coat to metal parts to reduce wear and tear and disperses heat to ease friction. Oil is more vital to diesel engines than gasoline engines because they operate under more pressure and produce soot. The excess …

Warut Wetsanarut/shutterstock Unlike gas-powered vehicles, diesel engines pressurize fuel using direct fuel injection systems. It’s then sprayed as a fine mist in the combustion chamber, making it easier to burn. This configuration makes diesel more efficient than gas, extracting mor …

coloritmail/shutterstock The fuel powering your engine needs air and heat to combust, which releases mechanical energy that spins the wheels forward. But where does the heat come from? In diesel engines, glow plugs heat the incoming air and fuel until it’s hot enough to burn, while g …
