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

Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the …

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.

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 …

Apr 1, 2021 · Diesel engines, like gas engines, are internal diesel combustion engines that convert chemical energy into mechanical energy. This process moves pistons up and down …

Nov 28, 2025 · Diesel engine, any internal-combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel (distillates of heavy hydrocarbons) injected …

In a compression-ignited system, the diesel fuel is injected into the combustion chamber of the engine and ignited by the high temperatures achieved when the gas is compressed by the …

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.

Sep 25, 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 …
