It’s not just the engine design—it’s thermodynamics. LiquidPiston isn't just playing with engine shapes—in its own words, it's also trying to reinvent the thermodynamic cycle.

Diesel has a slower burn rate that allows ignition, controlled by injector timing, sooner during the piston's cycle, and it has a higher energy density, containing around 147,000 BTUs of energy ...

The First Generation. 2000 – GM debuts the LB7 Duramax diesel engine with 300 hp and 520 lb-ft torque in ’01 ¾- and 1-ton trucks. The 6.6L V-8 turbodiesel engine featured aluminum heads with ...

While the first Otto cycle patent was filed in 1887, Rudolf Diesel developed an alternate cycle for use in an internal combustion engine, with his first patent filed in 1898.

Over time diesel fuel can degrade, losing its effectiveness and potentially damaging your engine. Here’s how long it stays fresh while being stored.

The engine is based on the iconic Cummins B6.7 platform and can produce up to 300 horsepower and 660 pound-feet of torque. Lower-output versions, such as 200 horsepower but with the same amount of ...

According to Chevy truck marketing director Mike MacPhee, a majority of Silverado HD buyers choose the 6.6L V8 L5P turbodiesel Duramax engine over the naturally aspirated 6.6L V8 L8T gasoline engine.

The 2024 GMC Sierra 1500 AT4X now comes standard with GM's Duramax diesel 3.0-liter inline-six. While it has less horsepower, the diesel's 495 pound-feet of torque is 35 more than the optional 6.2 ...

LiquidPiston says that it achieved the feat by combining the best features of the Otto, Atkinson, and Diesel cycle combustion engines, then packaging them into a modified rotary structure.
