Spark plugs can only ignite the fuel at one end of the chamber. A laser ignites the fuel in the middle of the chamber instead, burning more of the fuel and improving combustion efficiency by 27 per ...

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 ...

The Advance CurveAll engines require an ignition curve based both on the requirements of engine rpm and cylinder filling (volumetric efficiency). This means that at 3,000 rpm with the throttle open ...

For hundreds of years of human history, the invention that has defined our ability to travel, explore, and expand our boundaries has been the combustion engine. This hallmark of mechanical development ...

In response to stricter global emissions standards, automakers are looking for new ways to wring every last bit of efficiency out of the internal-combustion engine. In this Engineering Explained video ...

The pollutant emissions and high-energy consumption of combustion engines using conventional spark plugs have long been serious environmental problems. Now, it has been demonstrated that lasers can ...
