Here Are The 10 Most Reliable Diesel Engines To Ever Be Made
By JEFF HARPER
6.6L Duramax LB7
General Motors’ 6.6-liter Duramax LB7 was a state-of-the-art V8 diesel engine with four-valves-per-cylinder producing 235 to 300 hp and 500 to 520 lb-ft of torque.
In addition to a turbocharger and intercooler, the LB7 Duramax was equipped with the Bosch Common Rail Injector and used lightweight aluminum alloy cylinder heads.
BMW M57 Engine
Perhaps the automaker’s best diesel engine, the BMW M57 is a six-cylinder engine with three different displacements: 2.5, 2.9, and 3.0-liters.
The Common Rail injection system feature produced more efficient and cleaner combustion that pushed the engine to the top of the diesel ranking.
6.7L Power Stroke
Developed by Ford in 2011, the 6.7-liter Power Stroke diesel engine replaced the 6.4-liter Power Stroke and has proven highly durable and reliable.
While there have been a few reported problems, improvements to its design have kept it a top-of-the-class diesel engine that’s perfect for hauling and is still in use today.
Mercedes 2.1 OM611
The Mercedes 2.1 OM611 engine is the four-cylinder version of the diesel engine series that includes the OM 612 and OM 613 with five or six cylinders, respectively.
The OM series engines share many features, including the rail injection with Bosch injectors and aluminum cylinder heads with four valves per cylinder.
Chrysler 3.0L EcoDiesel
First introduced to European markets in 2011 by Fiat Chrysler Automobiles, later versions of the 3.0-liter EcoDiesel engines would make their way to North America in 2014.
Features like a graphite iron engine block and a high-pressure direct injection fuel system known as MultiJet II helped earn the 3.0-liter EcoDiesel its acclaim.
