ABSTRACT High-load HCCI combustion has recently been demonstrated with conventional gasoline using intake pressure boosting. The key is to control the high combustion heat release rates (HRR) by using ...

Fuel effects on combustion characteristics, including combustion robustness/stability, for partially premixed compression ignition (PPCI) combustion was investigated using Delphi’s second-generation ...

Like most things automotive, it depends. No two engines have exactly the same octane requirement, due to differing amounts of combustion chamber deposits and overall engine condition. Bore diameter ...

Everyone from Nostradamus to the Department of Energy predicts that internal combustion engines will provide primary propulsion for the majority of the vehicle fleet for a few more decades. But it's ...

Does your street-driven car ping now when it didn't use to? It may be suffering from octane creep caused by deposit buildup inside the combustion chambers. New engines on the dyno and regularly ...

From the 1920s until the 1970s, most gasoline cars in the USA were using fuel that had lead mixed into it. The reason for this was to reduce the engine knocking effect from abnormal combustion in ...

Anyone that’s ever topped off their tank or filled up a jerry can knows gasoline comes in different grades, from regular unleaded to pricey premium. Each “flavor” has a number that corresponds to its ...

Many passenger vehicles, including three-wheelers and motorcycles are fueled by octane 95 gasoline when octane 92 gasoline (petrol) is available at a lower price. Otto engine (petrol engine) is an ...

With a price difference of 24.4 cents between regular and premium gasoline on national average, many people are left wondering if they can save at the pump by filling up their gas tank with ...

Many passenger vehicles, including three-wheelers and motorcycles, are fueled by octane 95 gasoline when octane 92 gasoline is available at a lower price. Otto Engines (Gasoline Engine) can burn most ...

In mid-December we showed you the second custom build based on the new liquid-cooled engine Victory introduced a month ago at EICMA 2015, and we can now confirm that Victory Octane will be equipped ...
