Gas engines have significantly gained importance in the last few decades due to their efficiency and environmentally friendly characteristics. As an alternative to traditional diesel engines, they offer a clean and effective solution for various industrial applications. That is why the gas engine service industry is booming.
In this context, several manufacturers have stood out due to their innovative technologies and high-quality products. This article provides a comprehensive overview of the leading gas engine manufacturers and their noteworthy contributions to the industry.
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.
