The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight ...
The death of the internal combustion engine has been greatly exaggerated. Ford's EcoBoost line generates efficiency and power ...
Fuel injection offers drivers increased efficiency and power. But there's a common problem, too: carbon buildup on the engine ...
Exhaust Gas Recirculation (EGR) valve is a critical part of modern diesel and gasoline engines since it regulates emissions and reduces nitrogen oxides (NOx).
In Part 1, I regaled you all with the brief history behind the discovery of photochemical smog, and then proceeded to dazzle ...
Everything is gaining a light update, from the bike many of us started on, the Yamaha PW50, to the top-spec YZ450F ...
Since the rocker arms are locked together, all the intake valves (and exhaust valves, depending on the engine type) open wider, allowing more air in and creating more power.
With dual camshafts, one operates the intake valves and the other the exhaust valves. On a V-type, or horizontally opposed engine, each cylinder bank will have two camshafts, so there's four total.
However, various valves have been adopted to deliver variable valve timing for better air intake at different RPMs. In its simplest form, a Wankel rotary engine has just two moving parts: the ...
In a car's intake manifold, air enters at atmospheric pressure, rushing toward the intake valves at tremendous speed. But when the intake valves close completely, that onrushing air reaches a dead ...
The F50 came a year after the F355 and its V-12, derived from Ferrari's Formula 1 engine, also had five-valve heads accounting for a wonderful 60 valves in total.
