In a diesel engine, air and the fuel are infused into the engine at different stages, as opposed to a gas engine where a mixture of air and gas are introduced. Fuel is injected into the diesel engine using an injector whereas in a gasoline engine, a carburetor is used for this purpose. In a gasoline engine, fuel and air are sent into the engine together, and then compressed. The air and fuel mixture limits fuel compression, and hence the overall efficiency. http://www.xtengineparts.com/diesel-engine/

Homogeneous catalysis is an efficient alternative to its heterogeneous counterpart, and enables access to certain molecules that are not accessible through heterogeneous catalysis. Our high-performance phosphine ligands provide endless customization opportunities for catalytic processes. Phosphorus chemistry offers substantial diversity of structure, tunability and thermal stability, which leads to its use in many essential industries and an abundance of applications. http://www.runyvmat.com/organic-phosphorus-compounds/other-phosphine-ligands/

If you're looking for a toy that you can set your baby in and have a few moments to yourself, activity centers and freestanding jumpers will keep your baby occupied – and stationary, so you don't have to worry about them wandering off. Both offer your baby plenty of opportunities to safely explore and practice their fine motor skills like grasping, grabbing, and shaking, as well as gross motor skills like standing and bouncing. http://www.blmtoy.com/baby-walker/baby-walker-toy/

Gears with teeth on the internal side of the cylinder are known as "internal gears". An external gear can mesh with an external gear or an internal gear. When two external gears mesh together they rotate in the opposite directions. An internal gear can only mesh with an external gear and the gears rotate in the same direction. Due to the close positioning of shafts, internal gear assemblies are more compact than external gear assemblies. The spur gear slewing drive type is the more common one. http://www.ldb-slewdrive.com/spur-type-slewing-drive/

An air source heat pump (ASHP) is a type of heat pump that can absorb heat from outside a structure and release it inside using the same vapor-compression refrigeration process and much the same equipment as air conditioners but used in the opposite direction. Unlike an air conditioning unit, most ASHPs are reversible and are able to either warm or cool buildings and in some cases also provide domestic hot water. http://www.outesgroup.com/air-source-heat-pump/

This manufacturing process converts reinforced fibers and liquid resin into a fiber-reinforced plastic using a pulling method, as opposed to a pushing method used in an extrusion process. The first step in the pultrusion process is to saturate the fibers by pulling them through a resin impregnator containing a bath made of epoxy, polyurethane, polyester, and/or vinyl ester. Often, fillers and additives such as colorant, fire inhibitors, and UV retardants are blended into the bath to enhance the finished product. http://www.topskyfrp.com/frp-pultruded-square-tube/

Each mechanism can put either type of noise into some portion of an electronic system. Any pair of traces or wires on a PCB, IC, or cable assembly can experience two types of noise: common mode and differential mode noise. Common mode noise will have the same magnitude and polarity on each side of the interconnect, while differential mode noise has opposite polarity. Note that we haven’t considered intrinsic random noise sources like Johnson noise, which does not need an external source. http://www.softmagneticmaterials.com/

LED Tri-proof Lights are durable and eco-friendly alternative lighting systems to traditional fluorescent tubes. LED Tri-proof Lights are designed to withstand severe environments and will help you reduce your energy consumption by up to 80%. LED Tri-proof Lights are specifically built to withstand conditions susceptible to water, dust and corrosion impacts. Ningbo Qisen Lighting tri-proof Lights are Incredibly durable and long lasting, they are highly resistant to heavy impacts. http://www.toppoledlighting.com/led-tri-proof-light/

In other words, inductors resist or oppose changes of current but will easily pass a steady state DC current. This ability of an inductor to resist changes in current and which also relates current, i with its magnetic flux linkage, NΦ as a constant of proportionality is called Inductance which is given the symbol L with units of Henry, (H) after Joseph Henry.Because the Henry is a relatively large unit of inductance in its own right, for the smaller inductors sub-units of the Henry are used to denote its value. http://www.goldcoil.net/inductor/power-inductor/

Corrugated Box Digital Printing Machine he goes on to say, especially for corrugated, has been met with cautiousness. Also, it can be expensive and that must be weighed against the new opportunities that can be brought to the business. But, he continues, analog and digital are a great complement to each other and in the case of Swanline, “the analog processes have been strengthened by the addition of digital.” http://www.upg-corrugatedmachine.com/digital-machine/corrugated-box-digital-printing-machine/
