Why use diesel?
In today’s world, where fuel prices are increasing as a consequence of spiraling demand and diminishing supply, you need to choose a cost effective fuel to meet your needs. ETKPOWER recommends diesel engines due to their longevity and lower operating costs. Diesel fuel is less expensive compared with gasoline because it goes through a shorter refining process. And, diesel has a higher energy density, i.e. more energy can be extracted from diesel as compared with the same volume of gasoline. Today’s modern diesel engines are so quiet and require much less maintenance than comparably sized gasoline or gas generators (natural gas or propane). Diesel fuel cost per KW of electricity produced is normally (30%-50%) less than gas propane or natural gas generators. Water cooled diesel engines operate on average 20,000-30,000 hours before major engine maintenance is required. Water cooled gas models normally operate 6,000-10,000 hours because they are built on a lighter duty gasoline engine block. Air-cooled gas electric generators are normally replaced – not overhauled at 500 to 1500 hours. Gas generators burn hotter (higher B.T.U of the fuel), and hence they have a significantly shorter lives. ETKPOWER diesel GENSETS are powered by the world’s best engines to bring better power for high-end residential generators customers with larger homes to industrial, institutional, construction, healthcare, marine and military customers seeking prime power or critical emergency backup

Types of Diesel Engines

There are two classes of diesel engines: two-stroke and four-stroke. Most diesel engines generally use the four-stroke cycle, with some larger engines operating on the two-stroke cycle. Normally, banks of cylinders are used in multiples of two, though any number of cylinders can be used as long as the load on the crankshaft is counterbalanced to prevent excessive vibration. Generator sets produce either single or three phase power. Most homeowners require single phase whereas industrial or commercial applications usually require three phase power
