[ 1] Valve's first game was Half-Life, a first-person shooter released in 1998. [ 2] It sold over nine million retail copies. [ 3][ 4] Alongside Half-Life ' s launch, Valve released ...
A spark-ignition engine ( SI engine) is an internal combustion engine, generally a petrol engine, where the combustion process of the air-fuel mixture is ignited by a spark from a spark plug. This is in contrast to compression-ignition engines, typically diesel engines, where the heat generated from compression together with the injection of ...
Ford Vulcan engine. 2 overhead valves per cylinder, pushrods, rocker arms. The Ford Vulcan is a 3.0 L V6 engine designed and built by the Ford Motor Company. It debuted in 1986 in the newly launched Ford Taurus. Ford went on to install the Vulcan V6 in a variety of car, van, and pickup truck models until the 2008 model year, after which ...
Capacitor discharge ignition ( CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, turbine -powered aircraft, and some cars. It was originally developed to overcome the long charging times associated with high inductance coils ...
An overhead valve (OHV) engine, sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead ...
Ignition timing. Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of ...
The 16-valve 1.8-liter straight-4 produced 139 PS (102 kW; 137 bhp) or 56.7 kW/liter, almost 25% up from the 45.6 kW/liter for the previous 8-valve Golf GTI engine. The GM Quad 4 multi-valve engine family debuted early 1987. The Quad 4 was the first mainstream multi-valve engine to be produced by GM after the Chevrolet Cosworth Vega. The NA ...
