Carburetors used as intake runners A cutaway view of the intake of the original Fordson tractor (including the intake manifold, vaporizer, carburetor, and fuel lines). An inlet manifold or intake manifold (in American English) is the part of an internal combustion engine that supplies the fuel/air mixture to the cylinders. [1]
The Ford Modular V8 engines and the V6 Cologne use either the Intake Manifold Runner Control (IMRC) for four-valve engines, or the Charge Motion Control Valve (CMCV) for three-valve engines. The SVT edition (in North America) and ST170 edition (in Europe) of the Ford Focus added IMRC to the Ford Zetec engine .
In this design the cylinder wall contains several intake ports placed uniformly spaced along the circumference just above the position that the piston crown reaches when at BDC. An exhaust valve or several like that of 4-stroke engines is used. The final part of the intake manifold is an air sleeve that feeds the intake ports.
The engine's Variable-length Intake Manifold (VIM) switches between a long intake manifold at low engine speeds and a short intake manifold at higher engine speeds. Proton cars use a longer intake manifold to achieve slower air flow; as it was found that promotes better mixing with fuel. The short intake manifold allows more air in faster.
Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
The cylinder head intake and exhaust ports and intake and exhaust manifolds are shape optimized for better volumetric efficiency. Mitsubishi lowered the friction of the engine by including elastic grinding of the valve stems, adopting a high-efficiency shroud equipped plastic impeller in the water pump and using 0W-20 low-viscosity oil.
All M112 engines have silicon/aluminum (Alusil) engine blocks with a 90° vee angle. The aluminum SOHC cylinder heads have 3 valves per cylinder. All use sequential fuel injection with two spark plugs per cylinder. All have forged steel connecting rods, a one-piece cast camshaft, iron-coated aluminum pistons and a magnesium intake manifold.
The Mercedes-Benz M273 engine is a V8 automobile piston engine family used in the 2000s (decade). It was based on the similar M272 V6 introduced in 2004.. An evolution of the M113 V8, [1] all M273s have aluminium engine blocks, sequential port fuel injection, fracture-split forged steel connecting rods, a one-piece cast crankshaft, and a magnesium intake manifold.
