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 chamber during 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 these explosions …

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 inside cylinders, …

Nov 28, 2025 · diesel engine, any internal-combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder, where combustion and expansion …

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 creates an …

May 28, 2025 · Diesel engines are integral to many industries, powering everything from vehicles to heavy machinery. If you're looking to understand the basics of how diesel engines operate, you're in …
