Performance
In demanding oil and gas applications, dependability is everything. That’s where the superior uptime and productivity of the QSK23 makes the difference.

Dependability makes the QSK23 the right engine choice. Every time. Its Inline-6 configuration offers up to 950 hp (708 kW) to easily handle high load factors.

So whether you are spec’ing new equipment or repowering an existing unit, the QSK23 is the best way to improve performance, productivity and profits.

Designed for the well servicing market, the QSK23 delivers exceptional reliability and low cost of operation.

Its high-pressure injection (HPI) fuel system results in more complete combustion for superior engine response across the entire power curve and the lowest fuel consumption in its class. Its compact and balanced inline six-cylinder design and proven durability in the toughest well sites make it a great choice to repower vee engines of similar displacement.

The one-piece Ferrous Cast Ductile (FCD) iron pistons and robust cylinder head work to improve long-term durability and dependability. A one-piece cast-iron block, forged-steel crankshaft and a large-diameter camshaft ensure long, reliable performance between overhauls, with the capability of multiple rebuild cycles.

Rated from 760-950 hp (567-708 kW) in both emissions-certified and non-certified specifications, the QSK23 is the ideal choice for high power density applications. It has the proven technology you need to raise productivity and lower costs. Every Well.
