Generators for Sale – What’s New?

 When looking at generators for sale, one needs to be aware that diesel engines in general are constantly being improved. Rudolf Diesel, the inventor of the diesel engine, would possibly recognise a modern diesel engine as the product of the multi-generational refinement of his original concept because the principle remains exactly the same. All diesel engines produce power by burning a mixture of air and fuel to produce energy. In diesel engines, air is sucked into the combustion chamber where it is highly compressed. The extremely high temperatures generated by the high level of compression ignite the fuel, which is injected into the combustion chamber. The extreme heat vaporizes the fuel, which then ignites. The resulting explosive combustion drives the pistons down, rotating the crankshaft.

The efficiency of a diesel engine is tied to how efficiently the droplets of fuel are injected into a combustion chamber. The smaller and more widely distributed these droplets are, the better the efficiency of the diesel engine. The use of turbo chargers dramatically improves diesel engine performance and turbo chargers are found on most modern high-performance diesel engines. In pursuit of optimising fuel combustion, the level of sophistication the modern diesel engine has reached is staggering. Innovations that made significant gains include the introduction of common rail direct injection systems in the early 1930s. Even early diesel engines had attributes that made them superior to steam-powered engines and this inevitably led to the end of the steam era. Although materials technology and manufacturing tolerances have improved dramatically, the largest gains have come from improvements in fuel economy. The drive for ever better fuel economy has come largely from the commercial and industrial market segment. Power for utility scale backup, heavy load transportation, large scale agricultural businesses, and remote mining operations, to name a few, has driven constant innovation.

Generators for sale in the small capacity end of the market have tended towards petrol power, especially when units below 10 kVa are required. Engineers claim that there is still room for improvement with respect to fuel economy, power output, and emissions. Although petrol engines have become increasingly popular for powering generators for sale in the sub 10kVa capacity range, ongoing advances in diesel engine technology and fuelling systems will continue to make the diesel engine the choice of industry and commerce for the foreseeable future. Volvo, Cummins, Caterpillar, and the other leading diesel engine manufacturers allocate substantial resource to research and development annually and are continuously developing new, innovative technologies to improve and refine the diesel engine component in generators for sale.

Innovative Generators for Sale

As commercial and industrial entities replace outdated power systems, demand for generators for sale with higher power densities has further driven development. Manufacturers are developing generators that deliver more power from smaller and smaller physical footprints. Advances in engine technology allow for gensets that deliver up to 60% more power from the equivalent floor space than was previously possible. This reduces the costs of the site preparation, transportation, and installation of the unit. Modifications to the pre-chamber and combustion chamber allow maximum combustion efficiency, which extracts the most possible energy from the fuel. Digital controls are employed to allow more precision and more sophisticated control of fuel injection with respect to both injection rate and timing. Advancements in digitally controlled fuel injection have introduced the ability to produce as many as five injections of fuel for each combustion cycle, further increasing fuel efficiency. This results in more power and also reduces emissions.

Not only are the generators getting more powerful, but emissions are being reduced using innovations such as exhaust gas recirculation and catalytic conversion. Development has also been aimed at making the diesel engine quieter. Sound attenuation modifications have been introduced to reduce genset noise levels. Innovations include ceramic sound wave absorbing materials to strategic areas in the pre-chamber. Some manufacturers have clever technologies to squeeze the last gram of energy out of their units. Some state-of-the-art gensets offer combined heat and power (CHP) enclosures, which provide electricity for electrical loads and heat energy for any thermal requirements by using the excess heat produced by the engine.

Not Only the Engine Has Changed

 Historically, diesel fuel has had a relatively high sulphur content. This resulted in Diesel engines producing high particulate matter in their emissions on combustion. This is what produces the familiar clouds of black exhaust smoke that older diesel-powered gensets are known for. High sulphur diesel fuel clogs emission control devices and hampers combustion, leading to poor engine performance. Newer versions of diesel engines have been developed by fuel companies specifically formulated to contain very low sulphur levels. Diesel fuel is now available with sulphur content as low as 15 parts per million (ppm). This, ultra-low sulphur diesel burns extremely efficiently, produces good power, and has very low exhaust gas emissions. The latest generation generators for sale have typically been optimised to run on ultra-low sulphur diesel and are superbly efficient machines.

Market forces continuously demand more stringent genset requirements and manufacturers who wish to remain competitive need to innovate and improve their offerings. Continuing improvements in engine efficiency, fuel system efficiencies, and digital control can be expected going forward. Diesel-powered gensets will continue to be the go-to solution for commercial and industrial entities looking at generators for sale for the foreseeable future.

What are the Implications for Buyers?

It is clear that a new genset that employs leading-edge technology is going to be more powerful, take up less space, run more quietly, use less fuel, and produce less harmful emissions than older generation gensets do. If you have an older machine that has been on duty for a decade or more, it may be time to replace it. This is also a strong argument not to plumb for an older, used unit, if at all affordable, when looking at generators for sale in general.
