Understanding The Differences And Applications Of ISX And QSX Turbo Engines

ISX and QSX diesel engines were both developed by a particular company when the EPA (Environmental Protection Agency) ruled that the N114 engines produced too much air pollution. The new EPA regulations made the N114 engine obsolete and made it illegal to continue operating that engine model. It became necessary to develop diesel engines that met the EPA's requirements for for stricter emissions testing. Unfortunately, a lot of people know very little about these engines, and what they do know often gets the two engines confused. Here is more on the ISX turbo and QSX quantum diesel engines.

The ISX Turbo (Inline Straight-Six or Interact System Exchange)

This type of engine is known by all three of the names above. The names are used interchangeably as well. The biggest difference between this type of engine and the QSX is that the ISX is used in heavy duty trucks, transport trucks, and diesel-fueled cars, while the QSX is used for other types of vehicles. As such, the ISX may need more frequent ISX turbo repair as the engine wears down from regular and more frequent use than the QSX engine.

The QSX (Quantum System Exchange)

The QSX diesel engine is meant for boats, RVs, industrial machines, gas and oil companies, and off-highway machines. It never goes into cars or trucks, as it A) would not fit, and B) is too much power for standard vehicles. On the up side, the only time that QSX engines need to be repaired is when they are in constant use. That is usually when they are installed in industrial machines. If you own a boat, use a company freighter, etc., these transports are not used as often, and therefore the QSX engine lasts longer than the ISX turbochargers.

General Wear and Tear

In general terms, these engines usually last from the moment of installation until about a decade or so later. If the machine in which the engine is installed is operated intermittently, and/or is well-maintained, the lifespan is even longer. However, being diesel engines, you will need a specialist to address repairs and replacement parts. 

For the most part, the ISX and QSX are reasonably durable. When compared to standard engines, the ISX and QSX are superior in emissions testing, length of life, fuel efficiency, and energy conservation. Those features are valuable and important if they are installed in machines or vehicles that run or operate daily. Contact a company, like CTI Turbo, for more help.
