A crossflow T-head sidevalve engine The usual L-head arrangement Pop-up pistons may be used to increase compression ratio Flathead with Ricardo's turbulent head. A flathead engine, also known as a sidevalve engine [1] [2] or valve-in-block engine, is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve ...
Desmodromic poppet valve in a Ducati engine. A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases ...
The White Company engine was a mono block design. The Pierce-Arrow company introduced a production four-valve per cylinder T-head motor (Dual Valve Six) in 1918, one of the few, perhaps the only, multi-valve valve-in-block type engines produced. American LaFrance produced T-head engines for their fire engines until the 1950s.
A long block is an engine sub-assembly that consists of the assembled short block with crankshaft, cylinder head, camshaft (usually), and valve train. [5] A long block does not include the fuel system, electrical, intake, and exhaust components, as well as other components. A long block may include the balancer/damper, timing cover, oil pan and ...
It has smaller valves and stiffer valve springs than n/a 16V. Crank torque is 290 N⋅m (214 lb⋅ft) at 2950 rpm for the GT, and 280 N⋅m (207 lb⋅ft) for the FT. Other differences from the normal 16V redblock engine are that it uses a remote mounted oil filter (Away from block on exhaust side engine mount) and a windage tray.
1919 Napier Lion II aircraft engine with three cylinder banks. Any design of motor/engine,be it a V or a boxer can be called an "in-line" if it's mounted in-line with the frame/chassis and in-line with the direction of travel of the vehicle.When the motor/engine is across the frame/chassis this is called a TRANSVERSE motor.Cylinder arrangement is not in the description of how the motor/engine ...
A problem with high-speed engines that use poppet valves is that as engine speed increases, the speed at which the valve moves also has to increase. This in turn increases the loads involved due to the inertia of the valve, which has to be opened quickly, brought to a stop, then reversed in direction and closed and brought to a stop again.
The 4.8L and the 5.3L are smaller truck versions of the LS1 and were designed to replace the 305 and the 350 in trucks. The 4.8L and 5.3L engines share the same Gen III LS-series engine block and heads (upper end) and therefore, most parts interchange freely between these engines and other variants in the LS family.
