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 ...

Dropping spark plugs in favour of compression ignition technology could be key to the rotary engine’s comeback. Mazda surprised everyone at last week's Tokyo motor show by confirming the return of the ...

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 ...

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 ...

COMPRESSION IGNITION is, by convention, strictly the domain of diesels. The sparkplug-less ignition of a fuel-air mixture does however hold some promise when applied to petrol engines, and General ...

Billed as the Next Big Thing for the gasoline engine, Homogeneous Charge Compression Ignition (HCCI) allows for diesel-like operation wherein compression, not spark, combusts lean air/gasoline ...

Mazda had a simple explanation for why we had flown to Germany to drive its made-in-Japan next-generation Mazda 3 hatchback in prototype guise: Such early prototypes are allowed to roam German roads, ...
