A diesel engine is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is …

Jan 9, 2026 · 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 into the cylinder, …

Rudolf Diesel built his first well-known prototype of the high-compression engine in 1897. Since that time, the diesel engine has evolved into one of the world’s most capable and reliable forms of power …

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

What is a Diesel Engine? A diesel engine is a type of internal combustion engine that uses compression ignition to convert chemical energy into mechanical power.

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.

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, …

How does it work? Diesel engines, like gasoline engines, work by continuously repeating a four-stroke cycle: intake, compression, explosion and exhaust. This is what happens in each of the times: Intake: …

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 …

While gasoline engines rely on spark plugs to ignite a compressed mixture of fuel and air, diesel engines use the heat of compression alone to ignite the fuel. This process, known as compression ignition, is …
