Mazda has detailed the next-generation of its SkyActiv engine family, which will feature innovative compression ignition technology. While the new SkyActiv engine is still under development, Mazda ...
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 ...
General Motors will display an advanced technology compression ignition engine at its Milford Proving Grounds in Michigan today. The engine is a peek at new internal combustion engine developments at ...
Car manufacturers are delving deep into their boxes of tricks to make internal combustion engines more efficient. Infiniti unveiled a variable compression ratio engine last year, and hybrid technology ...
Mazda has revealed that it will introduce a new gas engine that uses compression ignition as part of its long-term tech development dubbed "Sustainable Zoom-Zoom 2030." Called Skyactiv-X, the new mill ...
However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...
What many consider the Holy Grail of combustion technology is one step closer to prime time. In the race to field energy-efficient vehicles, don’t count out internal combustion technology just yet. GM ...

Why diesel engines need higher compression than gas engines
Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...
SAE Transactions, Vol. 96, Section 4: RECIPROCATING ENGINES–SPARK IGNITION AND DIESEL (1987), pp. 614-623 (10 pages) A single-cylinder, variable–compression ratio, direct–injection diesel engine was ...
Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...
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 ...
