Hydrogen offers a compelling pathway to decarbonise compression-ignition (CI) engines by leveraging its high energy density, wide flammability limits and rapid flame propagation. In conventional ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...

You own a diesel-powered vehicle and are thinking of giving it a tuneup. But does your diesel even have spark plugs to change? The short answer is no, diesel engines do not have spark plugs. Instead, ...

In the current market, it is common to see new diesel trucks putting out over 1,000 lb-ft of torque from the factory. That's just in the consumer space. When it comes to heavy-duty industrial ...

A new study published in Engineering has explored a pilot-ignition reactivity-stratification (PIRS) combustion strategy for ammonia-fueled compression ignition engines, realizing a high ammonia energy ...

When comparing engine specs for nearly any combustion engine automobile, we see a number of variations available with differing outputs of horsepower and torque. We often have a choice of gasoline or ...
