Compression ignition basically is the term that is used for describing the manner in which diesel engines function. It happens when intake air—which often is combined with recirculating exhaust gas—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 ...

Most pickup trucks sold today have internal combustion engines. Passenger vehicles are powered by two main types of engines: compression, aka diesel, and spark ignition, aka gasoline. Besides the type ...

Could diesel particulate filter (DPF) regenerations become a thing of the past? A Southern California startup that is gaining the attention of OEMs believes it’s possible. For the past few years in ...

Scientists have developed a new combustion strategy for ammonia-fueled engines, hitting a 99.1% ammonia energy substitution ...

In the race to field energy-efficient vehicles, don’t count out internal combustion technology just yet. GM recently debuted its homogeneous-charge-compression-ignition (HCCI) system in two drivable ...

Homogeneous charge compression ignition (HCCI) engines combine a diesel's torque and fuel efficiency with a gas engine's cleaner emissions. The HCCI technique has been a goal of automakers since the ...

There is no shortage of people around the world today who seem pretty certain that the days of the internal combustion engine (ICE) as the primary form of propulsion for transportation are effectively ...
