Mazda is claiming the biggest breakthrough in combustion engine technology in decades with its new Spark Controlled Compression Ignition (SpCCI) engine. Why the fuss? Because it combines spark ...

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 ...

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 ...

BAD HOMBURG, Germany – Ever since Nikolaus Otto (1876) and Rudolf Diesel (1892) invented their respective “cycles” — the four-stroke internal combustion engine (ICE) and diesel compression ignition ...

ABSTRACT This study investigated neat n-butanol combustion, emissions and thermal efficiency characteristics in a compression ignition (CI) engine by using two fuelling techniques - port fuel ...

For more than a decade, automotive engineers and researchers have been struggling to come to grips with a way to build an engine that runs on gasoline while harnessing the efficiency and torque ...

Let's discuss something that is well known by diesel mechanics and hard-core enthusiasts but may not be fully understood by new diesel owners or people who may have heard the term "compression ...
