When I went to school for engine repair in the 1980s, we studied the differences between two- and four-stroke engine cycles extensively. If you're not familiar with engine strokes, understanding the ...

As we begin the last article in this series on the basics of the internal combustion engine, let's stop to review what we've covered during the last five articles. We began last May by detailIing the ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has ...

The piston ends its downstroke and begins moving upward, compressing the air/fuel mix until combustion happens and the whole cycle begins anew. This means that the high torque efficiency of the ...

Porsche patented a 6-stroke engine Outside of early Saabs, most gas-powered car engines are a 4-stroke Porsche's 6-stroke patent seems to indicate it could eke more power out of an engine Unless you ...

It's been a long time since the automotive world has bothered with the mixing of oil and gas of the two-stroke combustion cycle — but soon, it may come time to rid ourselves of four-stroke engines, if ...

Unit shown in the bottom of the photograph has been removed to show operation of the V-drive which is base of V-four engine.Ring gear shown on lower shaft of top unit is driven by a pinion mounted to ...

Even as EVs begin to encroach on ICE cars, the development of fuel-burning engines hasn't stopped. With almost 150 years of development in the Otto cycle internal combustion engine, you may think ...

With all the recent emphasis on electric vehicles, we often overlook the technology that still powers most cars on the road today. The internal combustion engine (ICE) has been at the heart of the ...
