Mar 16, 2024 · An easy-to-understand explanation of how a diesel engine works and why it's more efficient than a gasoline engine.

So-called dual-fuel diesel engines or gas diesel engines burn two different types of fuel simultaneously, for instance, a gaseous fuel and diesel engine fuel. The diesel engine fuel …

In diesel engines, internal combustion results in expansion of high-temperature, high-pressure gases, which in turn move pistons, transforming chemical energy into mechanical energy.

Apr 1, 2021 · How does a diesel engine work? A diesel engine works by drawing air into a cylinder and compressing the air to significantly increase its temperature before injecting …

Jul 28, 2025 · Diesel engines work by compressing air inside the combustion chamber, which raises the temperature. As the air is compressed, fuel is injected into the chamber, ignites, and …

But how does a diesel engine work, exactly? In this guide, we’ll break it down step by step—from basic definitions to internal components, turbocharging, emissions systems, and maintenance.

This 2 minute video provides a high-level explanation of how diesel engine combustion principles work to power your vehicle compared to conventional gasoline engines.

Both diesel engines and gasoline engines convert fuel into energy through a series of small explosions — or combustions. The major difference between diesel and gasoline is the way …
