If you want to know how a gas generator works, where they are used and how to get the most out of them, then you have come to the right place!

Gas engines — a comprehensive insight

The origins of the gas engine

The gas engine, a technological achievement of the 19th century, was developed in response to the limited capabilities of steam engines at that time. In 1860, Étienne Lenoir, a Belgian engineer, patented the first functioning gas engine.

This engine, known as an Otto engine, used a mixture of air and illuminating gas, which was ignited by a spark plug. Although this initial design was less efficient compared to later models, it paved the way for a revolution in energy conversion and utilization.

Function and Structure Basics

The gas engine is a specialized form of internal combustion engine designed to operate using gaseous fuels. Its main function is to convert the chemical energy of the gas into mechanical energy. The core component of the engine is the combustion chamber, where the gas-air mixture is ignited. During the ignition process, the hot gases rapidly expand and drive the piston, which in turn sets the crankshaft in motion.

Key components of gas engines include cylinders, pistons, valves, and spark plugs. Through continuous advancements in design and material selection, modern gas engines are continually improving in terms of efficiency, longevity, and environmental friendliness.

Differences between gas engines and diesel engines

Gas engines and diesel engines differ primarily in their ignition method. While gas engines mostly utilize spark ignition through spark plugs, diesel engines rely on compression ignition resulting from high compression temperatures.

Diesel fuel is classified as a liquid fuel, in contrast to the gaseous fuels used in gas engines. These distinctions result in variations in efficiency, emission profile, and operational behaviour between the two types of engines.

Overview of some gas engine manufacturers

In this section, we will examine some of the top gas engine manufacturers and their groundbreaking innovations.


The Jenbacher® brand is a prominent player in the field of gas engine manufacturing and is part of Innio Jenbacher GmbH & Co OG. Originally from the Austrian town of Jenbach, the company has specialized in gas engines since the 1950s.
