With traditional fixed valve timing, an engine will have a period of "valve overlap" at the end of the exhaust stroke, when both the intake and exhaust valves are open. The intake valve is opened before the exhaust gases have completely left the cylinder, and their considerable velocity assists in drawing in the fresh charge. Engine designers ...
Corliss Orville Burandt is an American engineer who invented a system of variable valve timing in automobile engines. Working through a 1965 Chevrolet Corvair, he designed a system of putting a sensor into the cylinder to optimize the fuel-air mixture during combustion.
The HR16DE is a 1.6 L (1,598 cc) naturally aspirated gasoline straight-4 engine, 16 valve DOHC; EFI; with variable valve timing. This engine has two fuel injectors per cylinder to improve fuel economy and reduce emissions. Bore: 78 mm (3.07 in); Stroke 83.6 mm (3.29 in).
In order to improve the optimisation of the valve timing for differing engine speeds and loads, the system is able to vary the timing and duration of the inlet valve opening. It achieves this by using a complex and finely machined mechanism to drive the inlet camshafts.
A Corliss steam engine – the valve gear is on the right of the cylinder block, on the left of the picture. A Corliss steam engine (or Corliss engine) is a steam engine, fitted with rotary valves and with variable valve timing patented in 1849, invented by and named after the US engineer George Henry Corliss of Providence, Rhode Island ...
